Maca for Fertility Q&A

Maca for Fertility Q&A

maca1. Q: Can I take too much Maca?

A: As with anything we consume, there is limit to how much we should consume. We would not want to eat too much of any one kind of food because it may not make us feel well. It is really about balance, and it is best to only take the recommended usage stated on the product.

According to the Maca experts of The Maca Team, “…some people report increased heart rate and nervous energy when they take too much. That’s why you should start with a conservative amount and work your way up slowly.”

Exceeding the recommended amount will not make it work faster or more effectively. It can be stressful for the body to exceed the suggested usage; it is best to start off at the lowest recommended amount and work up to a higher amount if necessary. Because each company is different, it is best to follow the directions for use of that individual product.

General suggested usage for maca is 1000-3000 mg a day.

2. Q: Can I take Maca with other herbs for fertility like Dong Quai and Vitex?

A: Yes. It is important to remember that maca is a food. In Peru it is a staple food much like our potato or yam, but has a much higher nutritional value. Its actions are based on its high nutritional value, which nourishes the entire endocrine system. Dong Quai and Vitex have different actions. Because other herbs for fertility have different actions and because Maca is considered a food, it is safe to combine with other herbs like Vitex and Dong Quai.

3. Q: At what point in my menstrual cycle should I start and stop taking Maca?

A: Maca is a nourishing food and may be consumed everyday throughout the menstrual cycle, even during menstruation.

4. Q: Is Maca safe to take during pregnancy? Does it have toxic effects on my baby?

A: Most nutritional supplements as well as herbal supplements are not suggested for use during pregnancy. Many herbs and supplements should not be used in pregnancy, but this is not true for all of them. This caution statement protects manufacturers from liability in case something adverse happens to the mother or baby during pregnancy while using the product. This caution also alerts the user to the potential for adverse effects. In some cases, this caution is a generalization and the risk is relatively low. Manufacturers cannot know the potential risks for each individual consumer, so putting a caution on the product makes it safer for consumers in general, minimizing risk to the mother and baby by having them not use the product at all.

Maca has been used for thousands of years by the peoples of Peru, and they eat it daily, even during pregnancy. Acute toxicity and cytotoxicity studies have shown no potential toxicity for Maca. Hundreds of thousands of people have used maca with no reported side effects. Foods like processed soy have shown to have adverse effects on the developing fetus as well as the mothers hormonal balance due to phyto-estrogens. Maca does not contain hormone-like substances like soy or other plants containing phytoestrogens.

We really have to think about other foods we consume daily like soda with aspartame, preservatives or food dye, all of these affect our bodies adversely, but they are deemed “safe” for regular use. Maca is a superior food as far as nutritional value goes, so why would this plant be a poor choice for pregnancy? Most maca is also organic. Because it is considered a nutritional supplement, and herbal supplement it is still advised that you get permission or talk to your health care provider about using Maca into pregnancy. It is always best to be on the safe side and let your healthcare provider know all herbs and supplements you are taking, especially if you are pregnant.

5. Q: I heard Maca is bad for you if you have thyroid problems? Is this true?

A: The maca we use is Lepidium Meyenii which is golden in color. There are other varieties of maca that have a variety of other colors including red, purple, and black. The darker varieties such as red, purple and black do contain higher amounts of iodine, which may not be good for some thyroid problems; this has not been linked to the golden variety that we use in our Fertilica Maca. On the flip side, some thyroid problems are linked to low iodine levels in the diet, so those other varieties may be helpful in those situations. As always, it would be best to talk to your health care provider about looking into using the darker varieties of maca for thyroid health. The darker varieties have also been linked, when consumed in very high amounts, to potentially causing goiters.

Maca has a balancing effect on the hypothalamus, which controls, stimulates, and balances the other endocrine glands: pituitary, adrenals, ovaries, testes, thyroid, and pancreas; therefore, Maca may actually help thyroid issues by nourishing the hypothalamus which controls the thyroid’s function.

Beth M. Ley (Knotts), Ph.D., nutritionist and author shares in her book MACA: Adaptogen and Hormonal Regulator (Native Food & Medicine of Peru) that under section 6 of the DSHEA (Dietary Supplement Health and Education Act) the following statement is listed for Maca: Supports the thyroid.

6. Q: Is it ok to bake with Maca or put in hot food?

A: Yes. Maca is a great way to add additional nutritional value to other foods, as well as boosting our fertility. It is easy to add to muffin mixes, bread recipes, porridge, oatmeal or pancakes.

7. Q: I have heard Maca has other benefits besides boosting fertility, what are they?

A: Studies have shown that Maca may help:

* Balance iron levels
* Decrease stress and anxiety
* Increase energy levels
* Help the body to utilize glucose for energy rather than process it for fat storage
* Lower high blood pressure, raise low blood pressure
* May help to normalize all of the bodies systems
* Increase stamina
* Increase mental clarity

8. Q: Why is Fertilica Maca powder suggested usage amount less than the typical “general” Maca dosage of 1500-3000 mg a day?

A: Our Fertilica Maca powder is a more concentrated form of maca, therefore less is needed to meet suggested daily amount. The fiber has been removed from the maca, leaving a more concentrated powder.

9. Q: I keep reading that Maca is an adaptogen, what does that mean?

A: Adaptogen is one of the many definitions for the therapeutic action a plant has. This term is well known by herbalists, naturopathic doctors, and other alternative medicine practitioners. This term may not be as well-know by medical doctors, so don’t be worried if your doctor does not know what adaptogen means.

Pioneer in Functional Medicine Frank Lipman, M.D. shares, “Adaptogens are a unique group of herbal ingredients used to improve the health of your adrenal system — the system in charge of managing the body’s hormonal response to stress. They enhance the body’s ability to cope with anxiety slowly and gently, without jolts or crashes. They’re called adaptogens because of their unique ability to “adapt” their function according to your body’s specific needs. Though their effects may initially be subtle, they’re real and undeniable.”

Adaptogens increase resistance to mind-body stress and enhance overall vitality and health through non-specific adrenal (known as stress glands) support. Plants recognized as adaptogens help to normalize the body’s functions even during diseased states, are non-toxic, nutritive, and have been deemed safe for long-term use. If a plant is an adaptogen, it may also have other action classifications such as anti-viral, immunostimulant or tonic. In general, a medicinal herb has many classifications as plants often have many actions.

    Hi Elizabeth,
    I have taken maca for the two failed IVF cycles that I have been through. I felt good on it but had bad acne outbreaks, mainly on my chest, back and arms. I am preparing for a third cycle and I would value your opinion as to whether I should use maca again. It seems to be an important supplement to help egg quality among other things, and I am 41, and need to increase my chances if I can, of course. Should I leave it, cycle with maca, or take the proper dose again regardless of the acne?
    Thank you!

    Hi Elisabeth,

    I have been taking maca together with vitex to hopefully heal my heavy and long period after D&C due to embroy stopping. Things did not get much better until I stop taking maca, continued with vitex only. I wonder why it is like this? could it be with hormone?

    While I am preparing for next conception, I am wondering if I can take maca with vitex again? my period is still as long as 10 days yet it gets normal with the bleeding amount. I am 44 now. Many thanks!

    • Dear Minna,

      I am sorry for your loss! I can only speculate about Maca, but perhaps it’s not needed quite, not the right herb for you, or wasn’t used long enough. Maca is incredibly nourishing… Both Maca and Vitex need to time to be effective and help the body return to balance. I am not clear on when the D&C and loss was. Allow the body time to recover and rebalance, and follow a natural fertility program for a minimum of three months time. If you continue to see positive changes with Vitex and feel you can benefit from Maca, it could be considered gain given what I know. Do start with the lowest general suggested dose of 500mg daily for a few weeks before increasing it if you feel the need to.

    Hi Elizabeth,
    Can my mom age 69 take Maca? She is going through grieving now, lost her husband(my dad) he died in her arms, unexpectedly major shock and stress, would you suggest this to her? i have mixture of three maca roots-black red and yellow. Thank you

    • Dear EliB,

      I am so very sorry! Maca doesn’t necessarily have an age limit, but I guess I can’t be sure it’s the best herb for your mom. Is going through grief counseling or does she have emotional support? I feel like it would be in her best interest to seek this out and then work with an herbalist that she can sit with one on one.

      Take care!

    I’ve been taking maca for a few months to help with poor egg health. I’m just below the “low” line. Still having issues conceiving, however the Maca root I am taking on the side of the bottle states “consult a health care practitioner for use beyond 3 months”, then it also says “also if you surffer from any psychological disorder and /or condtion such as frequent anxiety or depression”. I thought Maca root was to help with anxiety and depression (my reason for taking it also). I’m not on any medication for it, so would it mention that in regards to interference with medication? I’m taking the Vega Maca 750mg vegicaps. I live in canada, it was what was available.

    • Dear Jacey,

      I can’t be sure why these warnings are on the Maca product you chose. Is the only ingredient Maca? Have you contacted the manufacturer for their explanation. It’s my best advice to do so.

      Fertilica Maca can be used long term. Maca is a root vegetable and fertility superfood, used my the body like a food. It is not contraindicated in most cases, although it may not be for everyone.

      I think it’s best to pay attention to how you feel. If you feel good and see benefit or changes from using Maca, then perhaps there’s no need to worry.

    • Avatar

      Thank you Elizabeth!

      I will be contacting the manufacturer. There is three ingredients that are non – medicinal. I googled them and they may potentially be the reason there is that warning. However I plan to get in touch with them.

      I would love to purchase the Fertilica Maca, however I am in canada and the shipping is just too much. It also is in US dollars and much more expensive then the bottles I can get at my local Fiddleheads. I may switch back to the brand I was purchasing before. It all depends on the feedback from Vega.

      Thank you again, for your response 🙂 Have a great day.

    • Great idea Jacey! You are welcome and take care!

    Can it be taken in tea form and be as effective as the capsule? My husband and I have been drinking Maca root in tea form for a few weeks and I’m wondering if we should switch to capsules…

    • Dear Tami B.,

      Great question! The constituents one gets from tea often differ from those one gets from consuming the whole powdered herb. Tea will only allow you to consume water-soluble constituents. Both could be considered though. General suggested use of Maca is 500-3,000mg daily. If you enjoy the tea, consider it with the capsule or a Maca powder like Fertilica Maca Powder.

    What are the effects of going off maca? Would going off of it cause irregular periods?

    • Dear Cassie,

      Most consider weaning off of Maca over a week’s time when they are ready to stop using it. I do not know of any negative affects of stopping Maca or that the menstrual cycle will become irregular. It should not if hormonal balance support is not longer needed.

    I just purchased Magic Maca root powder as I’m TTC. As i was drinking it with my morning tea, I happened to notice a warning label about birth defects due to an unnamed chemical in the powder. Then I looked on forums and it appears that this warning is on many other brands. Do you know what chemical this is? and, is there a brand without this chemical?, b/c now I’m nervous about even using Maca.

    Should I take a break from Maca? I’m loving the benefits from it, but different website seem to have different suggestions on this. Since it takes awhile to build up in your system, it just seems like a few days off would be useless.

    • Dear Tim,

      We know Maca has been eaten as a staple in many diets across the World. I have not read evidence that it should be stopped after a certain amount of time. I think this is up to you! That said, we do also generally suggest weaning off of an herb (that can be taken long term) at about one year’s time to see how the body maintains any changes on its own.

    Hey, I am having my first blood test for hormone levels. I have been taking Maca for approximately 2 months. My Dr recommended that I stop taking Maca for now. How long will it take to for the Maca to be out of my system?

    • Dear Brandy,

      While Maca does not contain hormones itself, by nourishing the endocrine system it can influence hormonal balance. We feel it is best to not take any herbs that have an influence on hormones in the same cycle hormone testing is performed. That said, the body should properly metabolize Maca within a few days to a weeks time.

    • Dear Josephine,

      It is best to consult your healthcare provider about combining herbs that have potential to impact hormonal balance with herbs that do the same, like Maca. It is best not to combine the two on one’s own.

    Are there certain brands of Maca that you recommend during pregnancy? Gaia Maca sells two products: one that has just “Maca”, and one that has “Maca” and “Maca Root Powder gelatinized.” Also, it made me a little nervous because on the bottle it says ” Warning: this product contains a chemical known to the state of California to cause birth defects.” Pretty scary to read! You mentioned manufactures say this to protect themselves. Is this true or should I stay away from this brand? Please advise! I’m 5 week along. Ive had 2 miscarriages at 6 weeks and my instincts tell me maca could help balance my hormones so I can make it to 12 when the placenta takes over. You’re advise would be tremendous!

    • Dear Nelly,

      I am sorry to hear of your losses, but Congratulations on your pregnancy!!!

      Gaia is an amazing reputable brand. Our brand is Fertilica. We can’t suggest either brand of Maca be used in pregnancy without guidance from your herbalist, midwife or healthcare provider.

      Studies have yet to prove any potential toxicity for Maca. We know that many people have used maca with no reported side effects for thousands of years. It’s a staple food in Peru.

      There are however no studies that I know of to show if Maca is potentially harmful during pregnancy and this is why we can not suggest it be used in pregnancy without guidance. If you would like to take Maca into pregnancy, it would be best to do so under the care of your doctor, herbalist or midwife.

      If progesterone levels are a concern, this is the hormone the placenta takes over production of around week 20, do talk to your doctor about testing to see if there is concern (or hopefully not). It would be better to have support and guidance during this time that to do it alone!

      All my best!

    Is it safe to take Macca once you’ve ovulated? Is it safe to take Macca when you’ve confirmed you’re pregnant?


    • Dear Jenny,

      Fertilica Maca can be taken all cycle long and should be discontinued if you think you may be pregnant, or upon first determination of pregnancy. Maca is not to be used in pregnancy or while breastfeeding.

    Hello! How long does it take Maca to get out of your system? I stop taking it two weeks before my cycle and only took it for two weeks prior to cycle, so on two weeks off two weeks. I’m asking because I’m trying to conceive and I’m 4 days late. I wanted to know if I stopped two weeks before my cycle could the delay be because of the Maca? Or did the Maca do its job? I have not tested because I’m trying to hold off a little longer.

    • Dear Taylor,

      Hello! How exciting for you!

      Stopping Maca two weeks prior to the start of your last cycle means that Maca was not taken for 3-4 weeks before ovulation. It is highly likely that Maca was out of your system well before ovulation. Fertilica Maca can be taken while actively trying to conceive and is not known to build up in the system or delay menstruation. So, there shouldn’t be concern that Maca did anything other than offer its benefits.

      I wish you all the best!

    I’m 62, use your web for some info for my pregnant niece and found it very helpful. Thank you! Can you say if MACA is good for menopause? Thank you.

    Also, is it OK if my pregnant niece’s multi has a small (30-50 mg) amount of the red clover, schizandra, chaste tree in it? Thank you.

    • Dear Nadia,

      Thank you for supporting your niece and we wish for her a happy and healthy pregnancy, birth and baby!

      Regarding her multivitamin, be sure she is taking a prenatal multivitamin. If she is taking herbs in pregnancy, it is best that she be guided in doing so by her herbalist, midwife or healthcare provider. What I can share is that research has shown Vitex (Chastetree berry) safe for use into pregnancy. Learn more about the use of Vitex in pregnancy here... Schisandra has been used in pregnancy historically, but is not to be used during pregnancy unless otherwise directed by a qualified midwife, herbalist or healthcare provider. Red Clover may be supportive in pregnancy, but again only if she is being guided in using it.

      We are not specialists in supporting women beyond their fertile years, but I have read that Maca is a superfood used by Peruvians to treat symptoms of menopause. It would be best to continue your research of Maca and/or seek the guidance of a natural healthcare practitioner, or herbalist who works with menopausal women.

      All my best to you and your niece!

    • Dear Dave,

      In general, herbs have a 2-year shelf life. Many begin to quickly lose potency beyond that point, which can also be effected by how they are stored.

      It is ultimately up to you if you use the Maca, but we do not suggest using 5-year-old Fertilica Maca Powder.

    Hi, we are ttc baby # 2. I have a regular cycle, and ovulate just fine I think because I use ovulation kits and always get a smiley. We’ve been trying for just over 6 months and we conceived much quicker with our son. I bought maca root and chasteberry capsules. Can I take them both together in hopes to conceive quicker? Even though my fertility seems to be healthy, we just want to conceive asap. I’m getting more worried each month it doesn’t happen. Thank you!!

    • Dear Stacy,

      While Fertilica Vitex and Fertilica Maca can be taken together, there is no evidence, scientific or otherwise, that they will help you conceive “quicker”. Herbs and fertility superfoods that have the potential to impact hormone balance can cause temporary menstrual cycle shifts. I want you to know this before using both of these supplements. Cycle shifts for women with a seemingly normal menstrual cycle for many women are concerning. We see shifts a) a positive sign that the body is responding to the actions of the herbs and b) work themselves out within 1-3 cycles of use.

      All of this being said, it may be most helpful to consider making dietary and lifestyle changes to support relaxation and stress-reduction rather than take something you’re not certain you need. The article Top 10 Natural Fertility Boosters will teach you. Or consider working one on one with a natural healthcare provider who can help determine the best natural fertility program for your needs. We offer this through a Fertility Consultation.

    I purchased your liquid maca extract about 2 years ago but never oppened the bottle. I want to know it is expired but all it says is lot#2903. No expiration date. How can I find out if its still good?

    • Dear Patty,

      In general most tinctures (aka herbal liquid extracts) have a shelf life of around 2 years. We cannot determine the safety of use after this amount of time. If your liquid herbal extract has been stored in a cool dark place – a dry cupboard, away from the stove, microwave or refrigerator (this helps maintain their quality) – then it may be fine to use, but be sure to shake it vigorously for some time prior to use.

    • Elizabeth Willett, MA, CH

      Hello Natasha!

      Fertilica Maca can be started at any time during the menstrual cycle and taken all cycle long without a break. It is rare that menstrual cycle shifts occur from taking Fertilica Maca, but due to it’s ability to balance hormones, it may cause slight menstrual cycle shifts that often work themselves out. Should this happen, we feel it a sign of your body responding to Fertilica Maca.

      Take care!

    • Elizabeth Willett, MA, CH

      Dear Anna,

      Maca and Royal Jelly can be discontinued upon confirming pregnancy. Since there have been no studies on the use of Maca and Royal Jelly during pregnancy we can not state that it is proven safe to use during pregnancy, therefore they should be discontinued unless being guided in taking them by your healthcare provider or midwife.

    We are trying to conceive baby number two. We are on our 11th cycle and I temp so I do confirm ovulation. I still breast feed my son twice daily who is two. I am in the process of weaning him. I honestly think breast feeding is causing an issue with my fertility. My cycles are very very regular. I just ingested 1 tsp of maca powder for the first time. Do you think it will be beneficial regarding my situation? I’m worried maca may cause my regular cycles to become irregular. Any insight is appreciated.

    • Hi Andrea,

      Since your son is two and you are down to only two breast feedings a day, it may be time to wean and then consider maca. There is limited research on taking maca while breastfeeding, so we can’t recommend you take it while breastfeeding. Maca has been known to slightly shift some women’s cycles in length and ovulation timing, when first introducing it, but this typically regulates after the first cycle of use. A shift in your cycle could happen just from weaning your son, as well. In my experience, it is very common for many breastfeeding mamas to experience difficulties conceiving while breastfeeding, even at just 2 feedings a day.

      I am not sure of your age, but if you are over 35, remember, it is normal for it to take a year to conceive while not breastfeeding. Give it some time. I know you are probably feeling like you want to get this going, so click here to learn some tips on what you can do naturally to help you conceive while breastfeeding…

      Best of luck and a big high five for breastfeeding for 2 years, you go mama!

    Is macca good for women having fibroids?

    • Hi Reema,

      Because uterine fibroids are considered an estrogen dominant condition, which shows there is hormonal balance present, maca may be a good option for women with uterine fibroids as a hormonal support supplement. Maca is a nourishing food for the endocrine system, aiding both the pituitary, adrenal, and thyroid glands (all involved in hormonal balance.) Maca has the ability to affect key hormones in both women and men without containing hormones itself.

      Maca helps to stimulate and nourish the pituitary gland, acting as a tonic for the hormone system. When the pituitary gland functions optimally, the entire endocrine system becomes balanced, because the pituitary gland controls the hormone output of the other three glands.

      In women, maca works by controlling estrogen in the body. Estrogen levels that are high or low at the wrong time can keep a woman from becoming pregnant or keep her from carrying to term. Excess estrogen levels also cause progesterone levels to become too low. Taking maca may help to increase the progesterone levels which are essential to carrying a healthy pregnancy.

    Can you continue to take the “improve Egg Health Kit” after ovulation? Or do you need to take a break from TTC while doing this program? Thanks!

    • Hi Emma,

      It is fine to continue the Improve Egg Health Kit products after ovulation, discontinue use of them once you find out you are pregnant. If you are concerned about not knowing you are pregnant and continuing these products you would stop L-Arginine after ovulation. If you find out your are pregnant slowly use less and less of the Maca over a weeks time.

    Is it normal to experience nausea & upset stomach with Maca?

    I’ve been using about 1/2 teaspoon for 10 days in smoothies.

    I have an underactive thyroid and PCOS and am using diet & acupuncture to boost my energy levels. (I have felt lousy for about 3 weeks though so it might be something else.)

    • Hi Heather,

      Maca may cause upset stomach in some people, be sure to take it with food (if you are prone to upset stomach) which it sounds like you are. You could try to do 1/4 teaspoon, 2 x’s a day and then see how you feel.

      The change in diet and lifestyle may also be taking a toll on digestion as your body is adjusting to all the changes, give it some time and see how you feel. After eating you could try some peppermint, fennel or ginger tea.

    Hi Dalene,

    Thank you for your reply to my earlier query. I have been using the Fertilica Omega and love the product. I just have a concern in regards to the flax oil. Is it safe to continue using it.


    • Hi Candni,

      I just replied to another similar question about flax oil. There seems to be a rumor about that flax oil may increase estrogen. Here is my reply to her which should answer your question as well:

      There has been one main study that has been circulating in which it was found that flax seeds may increase excess estrogen in the body because of the high levels of estrogen found in the urine of the test subjects. Please keep in mind that in order to receive any nutritional benefits from flax seeds they must be ground or pressed for their oil content because otherwise they are not digested by our bodies. The results of this testing on flax showing higher levels of estrogen present in the urine may be due to the fact that the high fiber content of the flax seeds removes excess estrogens from the body which is excreted in urine.

      It has also been found that flax seeds are one of the greatest plant sources for lignans. Lignans act as plant hormones. When bacteria in the digestive tract acts on the lignans they are converted into phytoestrogens. Lignans have been found to be anti-estrogenic on estrogen receptor–positive breast cancer.** It is thought that lignans boost production of a substance that fastens on to human estrogen and then it is carried out of our bodies via urination. We do know that the high fiber and lignan content of flax helps to remove excess bad estrogens from the body. Lignans also help prevent healthy cells from free radicals.

      While flax is phytoestrogenic ,which means that it has the propensity to mimic estrogen, there may need to be more research to claims that phytoestrogens actually increase excess estrogen. Excess estrogen has been linked to fueling the growth of uterine fibroids, endometriosis, ovarian cysts and some cancers. But it appears in recent studies that the high fiber and lignan content in flax actually helps to remove excess estrogens which may actually help estrogen fueled fertilty issues.

      So from what I have read flax oil consumption promotes healthy estrogen activity in the body which is important for a healthy menstrual cycle and should not affect the menstrual cycle negatively. The high content of omega-3 fatty acids present in flax seed has been found to reduce breast pain and dysmenorrhea (painful menstruation). While taking omega-3 supplemtents may promote healthy estrogen function, it may also be best to also supplement with other omegas as well. A high quality fish oil helps to receive other esstential fatty acids rather than just one for a more balanced approach to supplementing with omegas.**
      -Christiane Northrup, MD, Women’s Bodies, Women’s Wisdom, Bantam Books, 2010

      For pregnancy as well it may be best to supplement with a balanced fish oil supplement that contains a wide variety of omegas. Our Fertillica Omega contains Borage oil which is not recommended for pregnancy due to its ability to cause mild uterine contractions.

      I hope this helps you understand flax more!

    Could you clarify if it is safe to take maca, spirulina and bee pollen after an embryo transfer in a smoothie everyday.

    • Dear Chandni,

      If you are still taking medicaitons for fertility after your transfer we advise against using Maca. If you would like to continue these supplements into pregnancy and you are not taking any fertility meds please get the approval of your doctor. We have not found any research that shows these supplements are unsafe for the baby or mother during pregnancy. If you or your husband (sperm) have a history of bee allergy in the family it is not recommended that you use bee products during pregnancy.

    Hi, is Maca safe to use AFTER you find out you are pregnant?..or during pregnancy?

    • Hi Anthea,

      Women in Peru have been consuming Maca for thousands of years during pregnancy and breastfeeding, but it is part of their daily diet. It would be best to consume Maca with other foods, for example: in a smoothie rather than take capsules if you are pregnant. It may also be best to start off at the lowest dosage if you choose to consume it during pregnancy. As always let your doctor know you are interested in taking this supplement.

      Best wishes,

    Hi ,

    How long does it take for Maca to start working on you ? Is there a time frame based on statistics for example. Also how would one know how many bottles they need?

    Also I would like to buy Maca through paying by western union is it possible? What is the procedure?
    Thanks for answering


    • Hi Sirine,

      Every person is different, though it may take 3-6 months of consistent use to achieve full benefits of maca. Our Fertilica Maca powder has 73 servings. 1 serving a day, lasts around 2 and a half months. The Fertilica Maca caps last 50 days.

    Is the liquid form of Maca more potent than the Fertilica Maca powder?

    • Hi Krystal,

      With liquid extracts in most cases you get a more efficient way to receive the benefits of the plant, that is because the alcohol extracts the medicinal and nutritional qualities from the plant and the alcohol also makes it easier to absorb into the blood stream. Our Fertilica Maca is a concentrated form of maca and is more potent than some of the others on the market.
      So it is comparable to the liquid extract. It really depends on how you like to take it. The powdered form make it easy to use in other foods. The liquid extract is quick and easy. The capsules are great for when you are in a hurry and you don’t like alcohol. Maca is first and foremost a food that has a super nutritional value and mixes well with other foods such as breads, oatmeal and smoothies, I even read it is good to put in homemade salad dressing.

      Hope this helps,

    I’m nursing my 6 month old that I conceived after doing the cleanse and taking maca and vitex. Both really helped with pms symptoms. Can I take Maca while nursing?

    • Hi NursingMommy,

      Maca is a food that is consumed daily in South America, of the thousands of people that have used it for thousands of years, there have been no reports of toxic side effects. Native Peruvians have used Maca during pregnancy to help maintain nutritional levels and a healthy full term weigth of the baby even at over 12,000 ft. above sea level. Most babies born at that altitude are born with a lower birth weight, not those babies, and this is attributed to eating maca daily. Those mothers also exclusively breastfed their babies while continuing to consume maca.

      I am happy to hear of your success with the cleanse, vitex and maca prior to conception. I am also so glad to hear you are breastfeeding!

    Can you take Maca when you are nursing? Thank you

    • Hi Sandi,

      Because maca is a food it is fine to use while nursing, as always because it is also considered a nutritional supplement let your doctor know you are taking it if they ask.

    will Maca help improve my fertility if I have PCOS? I have one to two cycles a year is this a good start to start rebalancing my body?

    • Hi Kristen,

      Yes, in women, maca works by controlling estrogen in the body. Estrogen levels that are high or low at the wrong time can keep a woman from becoming pregnant or keep her from carrying to term. Excess estrogen levels also cause progesterone levels to become too low. Taking maca may help to increase the progesterone levels which are essential to carrying a healthy pregnancy.

      PCOS is considered an estrogen dominant condition. Maca alone cannot reverse the effect of PCOS on your body, it really would be best to read over our entire PCOS Fertility Guide at this link:

    Is maca safe to take while on fertility medication such as follistim?

    • Hi Joanna,

      Maca is a food supplement and is safe in most instances, here at NFI we do not recommend taking any herbs for fertility while on fertility medications. You could provide your doctor with information on Maca, and then you would need to get their approval for you to take it with your medications.

      All the best,

    Is it safe to take maca and pregnacare supplement together?

    • Hi Peace,

      I am not familiar with Pregnacare, but from the looks of the website it is a vitamin supplement. If it is just a prenatal vitamin it would be fine to take with Maca.
