Vitex… Fertility Super Herb?

Vitex… Fertility Super Herb?

Article Overview

Vitex is a beautiful shrub native to Greece and Italy whose berries have been used in herbal medicine for centuries. It is considered one of the most popular herbs in Europe and other Western nations for the support of gynecological imbalances.

Modern clinical research and traditional use of Vitex have shown its amazing ability to help balance fertility hormones. Since Vitex does not contain hormones, it has a supportive, gentle and non direct action on the body. Vitex is one of the most useful fertility herbs available to us.

How Vitex Works

Our current understanding of Vitex is that it has a supporting and regulating effect upon the pituitary gland. The pituitary is known as the “master gland” because it controls many vital bodily functions such as sending chemical signals to the ovaries, telling them how much hormones to make. This communication is known as the hormonal feedback loop.

Vitex has been shown in studies to:

Vitex is one of the best fertility herbs available to us when it comes to balancing hormones and regulating the menstrual cycle.

Inhibit follicle-stimulating hormone (FSH): Vitex increases the secretion of luteinizing hormone (LH), which in turn increases progesterone.

Lengthens a short luteal phase: Studies have shown Vitex to be effective at lengthening the luteal phase. While it does not contain any hormones itself, it does help the body to increase its own production of luteinizing hormone (promoting ovulation to occur), which in turns boosts progesterone levels during the luteal phase of the cycle.

Increased progesterone levels: Vitex has been shown to stimulate the formation of the corpus luteum. The corpus luteum is responsible for the secretion of progesterone. In a study of 45 women, 86% responded positively with normalized or significantly improved progesterone levels.

Reduces advancement of mild endometriosis: Vitex is used in Germany by gynecologists to treat mild endometriosis and prevent it from advancing.

May help prevent miscarriage: Vitex has a beneficial impact on progesterone levels. If miscarriages are due to low progesterone, Vitex may help to normalize or increase progesterone levels. Vitex may be considered safe to use during pregnancy, but make sure to consult with a healthcare practitioner when using this herb during pregnancy. Also make sure to read our ‘Use During Pregnancy’ section below.

Relieves PMS: Clinical research has shown that Vitex may be very beneficial for PMS symptoms, especially depression, headaches, rashes, acne, allergies and sensitivity of the breasts. In one study improvement of PMS by the first month was experienced by 32% of the women. By the third month 84% of the women experienced improvement of their PMS.

Lack of menstruation (amenorrhea): In a study of 15 women with amenorrhea, 65% had resumed a menstrual cycle by the sixth month of use. Progesterone levels also increased.

Irregular menstruation: Vitex has been shown to help balance both an absent menstrual cycle as well as aid a menstrual cycle that is heavy or too frequent.

Uterine cysts: Vitex has been found to be helpful at reducing cysts that are growing within the smooth muscle layer of the uterus.

Stabilization of menstruation after stopping birth-control pills: After discontinuing estrogen-containing birth control pills, Vitex taken for several months has been shown to help stabilize the cycle and induce ovulation more quickly.

Helps stimulate milk production in new mothers: For over 2,000 years Vitex has been used to help stimulate mother’s milk. Begin using Vitex right after birth and continue for 10 days or more as needed.

Acne: Several studies have shown an improvement in the skin with the use of Vitex. Along with appropriate diet changes Vitex may help acne.

Most hormone related issues that disappear once pregnancy begins and then return after breastfeeding ends can be supported by the use of Vitex.

How to Use Vitex

For optimal results Vitex should be taken long-term. Clinical research shows that Vitex may start working within 10 days, but full benefits may not be experienced until 6 months or longer. For PMS, results are normally seen by the second menstrual cycle, but for lasting changes it may need to be taken for up to a year or more depending on how long the imbalance has been present.

Vitex is making fundamental changes in the delicate chemistry of the body, this is why it takes some time to have an effect. Since Vitex is a harmonizing and nourishing herb, it works behind the scenes to restore balance in a gentle way. Unlike a refined synthetic drug which forces the body to change, Vitex works to nourish and support the system bringing about long term balance.

Vitex Use & Dosage
Vitex is generally suggested to be taken once a day in the morning on an empty stomach (half an hour before breakfast). If Vitex is being used as part of an herbal blend containing other herbs, use as directed on the bottle. Vitex should be used all month long without a break.

  • Capsules: 900-1,000mg a day
  • Tincture: 60-90 drops a day

Which is the best Vitex to take?
Vitex comes in many forms, loose herbs, capsules, tea, tincture and powder. We find that capsules and tincture offer the most consistent results since it is easier to control the dosage. Many of the compounds needed from Vitex are easily extracted in alcohol (tincture) versus water (tea). Vitex is very strong tasting, almost bitter, so I would not suggest making a tea unless you blend other herbs with it, that is one reason capsules are so convenient.

Does Vitex Work for Everyone?

Vitex generally works for most adult women in their childbearing years (from age 18-perimenopause), but there are some cases where it may have no effect.

Women who have less than ideal lifestyle habits will probably not experience the full effects of Vitex. For those who have low energy reserves, weak immune systems, eat mostly processed foods, have been on antibiotics or steroids for a while – changes in diet and lifestyle are necessary prior to beginning the use of Vitex. Without making these changes in addition to using Vitex, you may not experience results.

Perimenopause is the time leading up to menopause. Perimenopause typically begins at the age of 40. As perimenopause progresses toward menopause, it is normal for menstrual cycles to become irregular and for hormone levels to fluctuate. As ovarian reserve diminishes and egg health declines, FSH levels may rise. For some women Vitex may be helpful in maintaining regular cycles and lowering higher FSH levels, but Vitex cannot reverse the aging process. It may or may not be effective for women in perimenopause, each woman is different. Vitex cannot bring back the menstrual cycle in women who have gone through menopause.

Safety & Side Effects

Vitex has been used for over 2,000 years with no significant side-effects reported. Some minor and infrequent side-effects (1-2% of users may experience) have been nausea, gastrointestinal upset, skin reactions, and headache. Women with a history of depression taking Vitex for menstrual irregularity may experience an exacerbation of depressive symptoms.

Even though it has been shown to have no interference with oral contraceptives (birth control), due to limited research, Vitex should not be used in conjunction with prescription medications that contain hormones in case it may interfere with their activity.

Some women do experience a shift in their cycle when they first begin using Vitex. The length of the menstrual cycle may shorten or lengthen temporarily before it finally stabilizes. This is just the body balancing itself out and is completely normal.

Safety ratings

  • German Commission E has approved the use of Vitex for menstrual cycle irregularities, premenstrual disturbances, and mastodynia.
  • The Botanical Safety Handbook has categorized Vitex as a class 1 herb. Class 1 herbs are herbs that can be safely consumed when used appropriately.

Vitex use During Pregnancy

It is believed that Vitex’s ability to increase progesterone levels has explained the positive results seen by herbalists and midwives who used it to help prevent recurrent miscarriages in women. No studies on humans have been done yet supporting this, only traditional use. There have been reproductive toxicology studies with female rats where they were given up to 80 times the concentrated used clinically in humans, showing no difference in offspring compared with the rats given none.

German research shows Vitex can be taken safely through the end of the third month of pregnancy and may help prevent miscarriage. Vitex is still considered safe to take after the third month, but it is thought that it may stimulate lactation too early, so for this reason it is suggested to not continue after the third month of pregnancy. Also, during the third month of pregnancy the placenta takes over progesterone production, so Vitex most likely won’t be needed.

If you are deciding to use Vitex during pregnancy, we suggest you consult with an herbalist or midwife for guidance and supervision.


Vitex is a fantastic herb for fertility, helping with a range of issues such as PMS, low progesterone, lack of ovulation, irregular menstrual cycles, lack of a menstrual cycle, acne and so much more. Vitex offers many benefits but requires patience and consistency of use. I find that it works best when used all month long and taken as one dose in the morning on an empty stomach.

  1. Hi, I’m 28yrs and I’m trying to get pregnant for 10months. After a conversation with my Naturopathy doctor, I started using this week a several supplements as Vitex (400mg – 2 per day), EPO (1000mg just the days 15 to 28 during cycle), Indole 3-carbinol (2 per day), multi-vitamins, and other immune support capsules. I have a history of a Leep few months ago and a cysts on my ovaries, but in general my health is ok. I just a little worried about what can cause a delay in to get pregnant. Do you think is correct the way I taking the supplements? I appreciate all your help.

  2. Hello,
    I was diagnosed with PCOS as a young teen with abnormal periods. I started taking Vitex 400mg since last June 2016. In the beginning I was taking one capsule three times a day. After the first three months I started taking it twice a day. I took it everyday and had a normal period this past August and September but not in October. They were normal periods but my September period was a week late. What dosage do you suggest? I want to conceive in a few years so I need some desperate advice.


    • Dear Raven,

      Can you share what “normal” was like and then how it differed in October? General suggested use of Vitex is 900-1,000mg daily each day of the menstrual cycle. That said, we know there are other herbs that work synergistically with Vitex to support the body trying to achieve hormonal balance with PCOS. Diet is key as well. In fact many healthcare providers believe that many women reverse PCOS by making dietary and lifestyle changes. So, that said, consider learning about a PCOS Fertility Diet and those other herbs here…

      I hope this is helpful!

  3. Thank you very much for your support Elizabeth! It was very helpful.
    All the best to you too.

  4. Hi. I need advice on how to wean off Vitex. I am 7 weeks pregnant and have been taking 15 drops of Chastree berry tincture every morning since one month before I conceived. I have had two miscarriages before. And now, I am worried about stopping it and also worried about continuing taking it. My miscarriages were both around my 5th week. So I”m finally the furthest I’ve been. How do I wean it off? Should I get tested before doing so? I would aprpreciate some advice, Thank you very much. Bruna.

    • Congratulations Bruna! What wonderful news!

      Now is the time to find a natural healthcare practitioner, herbalist or midwife near you to work with (if you have not already). They are best able to help you know if testing is appropriate. If past miscarriages were due to low progesterone, then certainly do talk about testing progesterone levels before weaning off of Vitex

      If using herbs to try to prevent miscarriage, the general approach is to continue your program until at least 2 weeks past the last weeks’ gestation of the previous miscarriage. Then at that point the daily dose can be decreased over a week’s time. One way could be to take decrease the dose by two drops daily for 7 days. German research shows Vitex can be taken safely through the end of the third month of pregnancy and may help prevent miscarriage, so do seek an herbal practitioner,or someone to work with who can monitor your herbal program.

      My best!

    • Hello Mrs. Kahn!

      At 40 menstrual cycles can naturally begin to change/shift. This is very normal actually. Vitex can support the body in maintaining this “new normal” and may help the length of the cycle balance out, but is not likely to cause the cycle to return to what it was in your 30s. General suggested use of Vitex is 900-1,000mg daily. So, increasing the dose you take may show you better results. Vitex is also able to have the greatest impact on hormonal balance when diet and lifestyle are optimal (when eating a whole food diet like the Fertility Diet, exercising daily, managing weight and stress levels, etc.).

      All that said, along with Vitex, an omega-3 supplement and multivitamin, consider learning the tips and about the supplements suggested in our guide to How to Increase Your Egg Health in 90 Days. There are also helpful tips in our guide to Preparing for Conception Over 40.

      I hope this is helpful!
