Why It Scores 7.0 — And The Label Line Behind Each Number
Active-ingredient transparency & dose
35% of scoreEvery ingredient and amount is on the panel: 2,000 mg myo-inositol, 50 mg D-chiro-inositol, 200 mg berberine HCl (97%), 400 mcg DFE methylfolate, 800 IU D3, 90 mcg K2 per three capsules. The inositol is half the 4 g a day used in Nordio 2019; the berberine is roughly a seventh of the usual 1,500 mg a day.

Evidence for the actives
30% of scoreMyo-inositol lowered fasting insulin and insulin resistance in a meta-analysis of nine PCOS trials (Unfer 2017; two authors work for an inositol maker), and the 40:1 ratio restored ovulation best among the ratios tested (Nordio 2019, small groups). Berberine improved insulin resistance and lipids in PCOS (Wei 2012), at doses far above this one.
Value vs buying standalone

Marketing Claims Vs. Reality
40:1 ideal ratio.
The panel gives 2,000 mg myo- and 50 mg D-chiro-inositol, a 40:1 ratio, the ratio that restored ovulation best in Nordio 2019.
May help promote a healthy menstrual cycle and support ovarian function.
Inositol at the 40:1 ratio supported ovulation in a small trial (Nordio 2019) at twice the daily amount in one serving here.
Supports metabolic balance.
Myo-inositol lowered fasting insulin in PCOS trials (Unfer 2017). The berberine in this product is too little to add much.
What Our Test Actually Found
The inositol carries this product
2,000 mg of myo-inositol is a real dose, and the 40:1 ratio matches the best result in Nordio 2019. Two servings a day would match the trial's 4 g; one serving is half.
Berberine is on the label more than in the effect
PCOS and blood sugar studies use around 1,500 mg of berberine a day. 200 mg is not that. If berberine is what you want, take a plain berberine HCl product alongside, after checking with your doctor.
Sensible extras
Methylfolate at 400 mcg and vitamin D3 at 800 IU are reasonable amounts for women of reproductive age; K2 adds little but does no harm at 90 mcg.
Full analysis: all pros & cons (7), buy if / skip if
- Every amount printed, no blend
- Myo- and D-chiro-inositol at 40:1
- Folate and D3 included
- Clean capsule, nothing else added
- Berberine 200 mg, far below trial doses
- Half the 40:1 trial dose per serving
- Testing lab not named
- You have PCOS and want myo- and D-chiro-inositol at the 40:1 ratio
- You want folate and vitamin D in the same capsules
- You prefer a label with every amount printed
- You want berberine at a studied dose: a 500 mg berberine HCl capsule three times a day is the usual protocol
- You are pregnant or trying to conceive: ask your doctor before taking berberine
- You take diabetes medication: berberine and inositol can both lower blood sugar
If you want inositol for PCOS with folate and D3 in one jar, this is a clean, transparent choice. For a real berberine dose you would still need a separate berberine product, and for the full 40:1 trial dose you would need two servings a day.
Women with PCOS often look at two supplements: inositol and berberine. This jar combines them, and the label is fully disclosed. Three capsules give 2,000 mg of myo-inositol and 50 mg of D-chiro-inositol, the 40:1 ratio that did best for ovulation in Nordio 2019, plus 200 mg of berberine, 400 mcg of methylfolate, 800 IU of vitamin D3 and 90 mcg of K2. The catch is dose. The 40:1 trial gave 2 g of inositols twice a day, so one serving is half of it. Berberine studies in PCOS and blood sugar use around 1,500 mg a day, so 200 mg is mostly a label ingredient.
Buy it for the inositol, not the berberine
Take three capsules a day with food; two servings a day would match the 40:1 trial dose. If you want berberine itself, pair it with a plain berberine HCl product, and talk to your doctor first if you are trying to conceive, are pregnant, or take medication for blood sugar.
If This Doesn’t Fit — Try These
01Nutricost Berberine HCl
Nutricost is our top pick and the right PCOS entry point — it keeps cost from becoming a barrier to running a full 12-week trial.
03Thorne Berberine
For PCOS this is the pick when NSF certification matters most, with one honest caveat: the current Thorne listing is the Dual Action formula — HCl and phytosome berberine in the same capsule — not plain HCl, so it does not replicate the exact 500 mg × 3 protocol the cornerstone PCOS trial used (that is Toniiq #2's job).
06Integrative Therapeutics Berberine
Integrative Therapeutics is the right pick if your practitioner specifically recommended it or you're already in the clinician-channel supplement ecosystem.
Quick Answers
Is Herbpy inositol with berberine good for PCOS?
The inositol part is well supported: myo- and D-chiro-inositol at 40:1, the ratio that worked best in Nordio 2019. The berberine dose is too low to add much.
How much inositol is in a serving?
2,000 mg myo-inositol and 50 mg D-chiro-inositol per three capsules. The 40:1 trial used that amount twice a day.
Can I take berberine if I am trying to get pregnant?
Ask your doctor first. Berberine is not recommended in pregnancy, and inositol use around conception should also be agreed with your clinician.
Does it contain the full berberine dose?
No. It has 200 mg; studies typically used about 1,500 mg a day.

The 40:1 ratio restored ovulation and improved hormone and insulin measures best.

Berberine lowered waist-to-hip ratio, fasting glucose, insulin, insulin resistance and LDL versus placebo.
