Hyperprolactinemia
Hyperprolactinemia is simply an elevated level of prolactin in the blood. Prolactin is the hormone responsible for stimulating milk production during pregnancy and breastfeeding (and levels are naturally high during these times), but when it is inappropriately elevated, it affects reproductive hormones and can lead to infertility.

ℹ️ Quick Facts
Quick Facts: Hyperprolactinemia
- Supplements Studied:0
Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
May enhance dopamine synthesis, which inhibits prolactin release
Has dopaminergic effects that may lower prolactin levels
Supporting Stack (Tier 2)
Involved in dopamine synthesis; deficiency may contribute to elevated prolactin
May help normalize prolactin levels; studied for hyperprolactinemic conditions
Adaptogen that may support hormonal balance; limited evidence for prolactin
Deficiency associated with higher prolactin; may help with bone health (often affected in hyperprolactinemia)
Adaptogen that may help with stress-induced prolactin elevation
How It Works
Hyperprolactinemia is elevated levels of prolactin, a hormone produced by the pituitary gland. Prolactin's main function is to stimulate breast milk production, but it also affects reproductive function in both men and women. Symptoms include irregular periods or no periods (amenorrhea), infertility, breast discharge (galactorrhea), low libido, erectile dysfunction in men, and osteoporosis from long-term elevation. Causes include pituitary tumors (prolactinomas), medications (antipsychotics, metoclopramide), hypothyroidism, and sometimes no identifiable cause.
CRITICAL: Hyperprolactinemia requires medical evaluation to determine the cause. An MRI of the pituitary is often needed to check for tumors. If caused by a medication, the doctor may adjust or change it. Prolactinomas are usually treated with dopamine agonists (cabergoline, bromocriptine) which are highly effective at lowering prolactin and shrinking tumors. Surgery is rarely needed. These supplements may provide modest support but cannot treat significant hyperprolactinemia or pituitary tumors. Always work with an endocrinologist for proper diagnosis and treatment.
* Vitamin B6 is a cofactor in dopamine synthesis. Since dopamine inhibits prolactin release, enhancing dopamine production may help lower prolactin. Evidence is limited but B6 is sometimes tried for mild elevations.
* Vitex (Chasteberry) has the most evidence among herbal supplements. It contains compounds that have dopaminergic effects and has been shown to lower prolactin levels in some studies. It's been used traditionally for menstrual irregularities.
* Zinc is involved in dopamine synthesis, and deficiency may contribute to elevated prolactin.
* Vitamin E has been studied with some positive results for prolactin reduction.
* Maca is an adaptogen that may support overall hormonal balance.
* Vitamin D deficiency has been associated with higher prolactin levels, and supplementation is important for bone health, which can be compromised by hyperprolactinemia.
* Ashwagandha may help with stress-induced prolactin elevation.
Expected timeline: Supplements may take 2-3 months to show effects on prolactin levels. Medical treatments (dopamine agonists) work much faster and more effectively.
