Women deal with A LOT every month while riding the never-ending hormone roller coaster. Unlike men (who function on a 24-hour cycle), our bodies work according to a monthly cycle.
If you’re like me, you’ll do anything (legal) to reduce the nightmare of PMS, cramps, breakouts, and exhaustion.
In this article, we’ll explore a promising herbal supplement called chasteberry (or vitex).
It’s one of the most acclaimed herbal remedies for women’s health. You’ll also find our list of the top 7 chasteberry supplements on the market.
Chasteberry is an herbal extract made from a small, brown berry from the chaste tree – a flowering shrub native to the Mediterranean, Asia, and North America.
It’s also known by its botanical name vitex agnus-castus – or vitex for short.
Funnily enough, the chaste tree berry was first used as a herbal tincture to suppress libido in men (monks, to be specific). Although, we don’t know if there is any truth to the claim.
Now, women predominantly use chasteberry extract to treat PMS, mastalgia, irregular periods, hormonal migraines, premenstrual dysphoric disorder (PMDD), polycystic ovarian syndrome (PCOS), and infertility.
There are dozens of studies examining chasteberry’s benefits for female reproductive system health.
Chasteberry contains an active compound called agnuside, which may influence hormones like prolactin, progesterone, estrogen, luteinizing hormone (LH), and follicle-stimulating hormone (FSH).
Let’s dig into some of the research.
If PMS is the bane of your existence, chasteberry may offer some relief.
This placebo-controlled study looked at taking chasteberry extract for 6 days before menstruation. Women who took chasteberry for 6 consecutive cycles saw significant improvements in headaches, irritability, depression, breast fullness, and bloating.
Chasteberry also reduces cyclical mastalgia (breast pain). Researchers think it may work by stimulating the release of dopamine – a “feel-good” neurotransmitter.
Lastly, just 40 mg/day may reduce the frequency of premenstrual migraines.
TLDR; chasteberry is a great natural supplement for reducing PMS symptoms.
If you have irregular periods, chasteberry may regulate your cycle by lowering the hormone prolactin. If prolactin is too high in the second half of the menstrual cycle, it interferes with ovulation.
This clinical study found 20 mg of chasteberry daily for 3 months normalized cycle length in women with hyperprolactinemia.
Plus, chasteberry may improve your chances of falling pregnant (if that’s your goal). Research on women struggling with infertility found taking a proprietary blend containing chasteberry increased pregnancy rates by 33%.
Disclaimer: Consult your doctor before taking chasteberry if you’re undergoing fertility treatment.
The drop in estrogen and progesterone levels during menopause creates annoying symptoms like insomnia, hot flashes, dry skin, and mood swings.
Chasteberry may naturally alleviate some menopausal symptoms. However, it works best with other herbs like dong quai, black cohosh, and red clover.

We want you to decide on the best product for your needs. To do that, you need to understand how we ranked.
Here are some factors we considered when researching the best chasteberry supplement.

We also boosted vitex supplements that are FDA-registered and audited (like Morphogen Nutrition).
We looked for quality products containing standardized chasteberry extract with at least 0.5% of active agnuside.
The products on the list offer doses ranging from 200 – 500 mg per capsule. These levels are therapeutic and safe.

We’ve listed the best chasteberry products to suit a range of budgets while never overriding quality.
Endometriosis is a painful disorder where uterine tissue develops outside the uterus.
Theoretically, chasteberry may help women with endometriosis by regulating hormone levels. However, there are currently no clinical trials to confirm it helps endometriosis.
Chasteberry may help new moms increase their milk production naturally. However, the evidence supporting chasteberry for lactation comes from old, low-quality studies.
Chasteberry is almost exclusively studied and sold as a supplement for women. However, it may be helpful for men in specific circumstances.
This study found that chasteberry extract may inhibit the growth of human prostate cancer cell lines. This is promising, but more clinical research is needed.
There is no standard recommended dose for chasteberry extract. Clinical studies have used 20 – 400 mg/day.
Always read the supplement facts on the label to see the suggested dosage. And speak to your healthcare provider if you’re unsure about your dose.
Chasteberry is safe to take every day. However, some women prefer to take it only during the follicular phase of the menstrual cycle (from day 14-28) and stop for 2 weeks.
You don’t need to take chasteberry indefinitely. If you’re using it to promote hormonal balance, a 6-month course should be sufficient. For women struggling to fall pregnant, chasteberry may be necessary for 12-18 months (or until a pregnancy occurs).
Chasteberry supplements are generally safe when taken at the recommended doses. Side effects are rare and may include digestive discomfort, headaches, itchy skin, and acne.
Chasteberry is an herbal medicine primarily for balancing hormones, so speak to your doctor if you have a hormone-sensitive condition or are pregnant or breastfeeding. Furthermore, chasteberry may reduce the effectiveness of oral contraceptives. We don’t want to be responsible for any unwanted pregnancies – please use an additional form of contraception if you’re on the pill.
