PMOS supplements: what the evidence actually says
In May 2026, a global consensus published in The Lancet renamed polycystic ovary syndrome (PCOS) to polyendocrine metabolic ovarian syndrome (PMOS) — a more accurate name for a condition that is hormonal and metabolic, not a problem of ovarian cysts. The condition is the same. Below is an evidence-based directory of the supplements studied for it, organized by symptom, with safety notes and review attribution on each linked page.
You may still see it called PCOS everywhere — that term will be in use for years. We use both.
From “cysts” to the metabolic reality
The old name implied the core problem was cysts on the ovaries. For most people it isn’t — insulin resistance and androgen excess sit upstream of the symptoms. After years of global consensus work, clinicians and patient organizations adopted polyendocrine metabolic ovarian syndrome to reflect that. It affects roughly 1 in 8 women (about 10–13% of reproductive age), and the WHO estimates up to 70% of cases may be undiagnosed.

Trying to conceive, pregnant, or breastfeeding? Read this first.
Many people with PMOS are also trying to conceive, and some supplements commonly discussed for the condition are not recommended in pregnancy. Berberine in particular should be avoided when pregnant or nursing. Do not start, stop, or combine supplements based on this page — confirm everything with the clinician managing your care, especially if you take metformin, thyroid medication, or anything that affects blood sugar.

PMOS supplements by symptom
PMOS shows up differently in different people. Start with what you’re actually trying to manage — each link opens a full HAA evidence page with dosing, safety, and product comparisons.
Insulin resistance & metabolic
Insulin resistance is common in PMOS / PCOS and can overlap with androgen and ovulation patterns. Start here if your clinician has flagged glucose, insulin, A1c, or metabolic markers.
Cycle regularity & ovulation
Irregular or absent ovulation is a defining feature. These are the supplements most often discussed for menstrual regularity and the LH/FSH ratio.
Acne & excess androgens
Elevated androgens drive the sebum and skin symptoms many people notice first. These target the anti-androgen pathway.
Androgenic hair thinning
Scalp hair loss linked to DHT and androgen excess — distinct from the metabolic picture and worth its own evidence review.
Weight management
Weight is harder to shift with insulin resistance in the background. Evidence here is more limited — set expectations accordingly.
Inflammation & lipids
Low-grade inflammation and unfavourable lipids are common metabolic features of the syndrome.
Foundational deficiencies
Correcting a genuine deficiency is different from supplementing on top of adequate status. These two are frequently low and worth testing first.
