How this protocol works
In plain language
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.
