PCOS — insulin, androgens & ovulation
One of 5 mechanistic pathways to 🌸 Female hormonal balance · 14 options
PCOS is most usefully understood as a metabolic condition with reproductive consequences. Insulin resistance raises ovarian androgen production and lowers SHBG, so more free androgen circulates, follicles stall and ovulation stops. Fix the insulin and much of the rest follows — which is why this pathway leads with metabolism.
The most complete workup on this page, and it earns it. Raised AMH with an LH:FSH ratio above 2 and low SHBG is the classic picture; 17-OH-progesterone is there to rule out congenital adrenal hyperplasia, which mimics PCOS and is treated completely differently.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
🧬 Myo-Inositol
Acts as a second messenger for insulin and specifically for FSH signalling in the ovary. Multiple RCTs show restored ovulation, improved insulin sensitivity and lower androgens — comparable to metformin with far better tolerability. The 40:1 myo-to-D-chiro ratio matters and most products get it wrong.
💉 Metformin
The pharmaceutical standard. Improves ovulation rates and metabolic parameters; the GI tolerance is the limiting factor for many.
🧬 Berberine
Head-to-head trials against metformin in PCOS show comparable metabolic improvement, with a better lipid effect in some.
🧬 Dihydroberberine
The reduced form. Same proposed mechanism as berberine with roughly five-fold better absorption, so a lower dose should reach the same plasma exposure — an entirely pharmacokinetic argument, and the outcome trials were run on berberine rather than on this.
🧬 NAC
Improves insulin sensitivity and ovulation rates in PCOS trials, and has been compared favourably to metformin. Antioxidant effects on oocyte quality are a separate proposed benefit.
🧬 Alpha Lipoic Acid
Insulin sensitisation; often combined with myo-inositol in trials.
🧬 Vitamin D
Deficiency is very common in PCOS and correlates with insulin resistance and worse ovulation. Correction improves menstrual regularity in trials.
🧬 Saw Palmetto
Weak 5-AR inhibition — relevant to the hirsutism and acne, not the metabolic driver.
🧬 DIM
Shifts estrogen metabolism; relevant where estrogen dominance accompanies the androgen picture.
🧬 Chromium
Modest improvement in insulin sensitivity in PCOS trials.
🧬 Omega-3 (Fish Oil)
Reduces androgens and improves insulin sensitivity in PCOS-specific trials.
🧬 Magnesium
Insulin signalling cofactor; deficiency is common in insulin resistance.
🧬 Zinc
Trials show improved hirsutism and acne scores in PCOS, plus its role in insulin signalling.
🧬 GLP-1 Support Stack
GLP-1 agonists are increasingly used in PCOS; this covers the nutritional gaps that come with them.

Frequently asked questions
PCOS is most usefully understood as a metabolic condition with reproductive consequences. Insulin resistance raises ovarian androgen production and lowers SHBG, so more free androgen circulates, follicles stall and ovulation stops. Fix the insulin and much of the rest follows — which is why this pathway leads with metabolism.
14 options are mapped to this pathway in the Vault, including Myo-Inositol, Metformin, Berberine, Dihydroberberine. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 10 carry clinical validation and 4 are mechanistic predictions.
The most complete workup on this page, and it earns it. Raised AMH with an LH:FSH ratio above 2 and low SHBG is the classic picture; 17-OH-progesterone is there to rule out congenital adrenal hyperplasia, which mimics PCOS and is treated completely differently. The markers worth checking are Fasting Insulin, HbA1c (Hemoglobin A1c), Total Testosterone, Free Testosterone.
Unproven is not the same as ineffective. Of the 14 options on this pathway, 10 have clinical validation and 4 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
