We tested 5 top-rated PCOS supplements for 4 months. Which one is currently #1?

Unexplained weight gain and fat accumulation around the belly.

That’s the #1 complaint women suffering from PCOS reported in our recent survey.

Second place?

“Feeling dismissed, misunderstood and underserved by the healthcare system.”

And it actually makes sense because PCOS just recently started getting the attention it deserves.

In fact, it’s now being recognized as PMOS (Polyendocrine Metabolic Ovarian Syndrome) because we now know that it comes down to three interconnected causes.

Insulin resistance, hormonal imbalance, and chronic inflammation.

But the problem is that typical remedies like contraceptives don’t treat these underlying drivers of PCOS and cause side effects on top of that.

So we ran a 4-month test with 60 women.

The goal: find a supplement to tackle the most frustrating PCOS symptoms at their actual root cause.

We tested:

• Bioma Probiotics

• Peach Perfect Inositol Multivitamin

• Daily Nouri Hormone Balance Probiotic

• Vita-PCOS Androgen Blocker

• Theralogix Ovasitol Plus

These 60 women were separated into 5 groups and took each supplement for 4 months.

We tracked results using weekly weigh-ins and self-reports on:

• Total weight loss

• Waistline reduction

• Cycle regularity

• Overall symptom improvement

#1 — Bioma Probiotics

The only supplement that tackled all three root causes of PCOS and delivered the most significant improvements across all metrics

What it is

A sophisticated supplement that delivers a unique combination of XOS, Tributyrin, and three Bifidobacterium strains to tackle insulin resistance, hormonal imbalance, and chronic inflammation simultaneously.

How it worked

This was the only supplement that made women who took it for 4 months say, “I’ll 100% keep using it after this test ends.” Bioma started working quickly, with most testers noticing weight loss and visible changes in belly fat within the first few weeks. For many, cycles became more regular along with significant improvements in hirsutism, hair thinning, and acne.

Price: $26.14 (currently 35% off, normally $40.21)

Data from weigh-ins and self-reports:

• Average weight loss: 31 lbs

• Average waistline reduction: 5.2 inches

• Cycle regularity: Significantly improved

• Overall symptom improvement: 9.2 / 10

Pros

• XOS lowers fasting glucose and reduces insulin resistance ¹

• Tributyrin lowers testosterone and LH and helps restore regular cycles ²

• B. lactis lowers LH and corrects the elevated LH/FSH ratio linked to anovulation ³

• B. longum boosts estradiol and FSH to support healthy ovarian function ⁴

• B. longum reduces IL-6 and TNF-α to fight chronic inflammation at its root ⁴

• Delayed-release capsules protect all ingredients from stomach acid

• Costs less than $1/day with the current discount

Cons

• Sells out often because of the high demand (especially during sale events)

#2 — Peach Perfect Inositol Multivitamin

The second most comprehensive supplement, but it leaves two of the three PCOS drivers unaddressed

What it is

An all-in-one PCOS multivitamin combining D-chiro inositol with omega-3, magnesium glycinate, zinc, and vitamin D3.

How it worked

The second best supplement of our 4-month test delivered meaningful improvements in weight, cycle regularity, and overall PCOS symptoms. But without anything to tackle hormonal imbalances and chronic inflammations, results plateaued noticeably from month 3 onward.

Price: $39.99

Data from weigh-ins and self-reports:

• Average weight loss: 24 lbs

• Average waistline reduction: 3.8 inches

• Cycle regularity: Significantly improved

• Overall symptom improvement: 7.1 / 10

Pros

• 40:1 inositol ratio addresses insulin resistance and supports cycle regularity ⁵

• Magnesium and zinc address common PCOS micronutrient deficiencies ⁶

• Vitamin D3 supports metabolic and reproductive health ⁷

Cons

• Lacks ingredients for hormonal balance and chronic inflammation support

• Improvements of PCOS symptoms plateaued from month 3 onward

#3 — Daily Nouri Hormone Balance Probiotic

Great for hormonal balance, but extremely one-dimensional

What it is

A synbiotic supplement combining a 7-strain Lactobacillus and Pediococcus probiotic blend with Ahiflower omega oil.

How it worked

Daily Nouri brought an interesting dimension to this test because it’s designed to support hormone balance through the gut microbiome. Women who took this supplement reported improvements in mood, digestion, and cycle regularity along with some weight loss.

Price: $32.69

Data from weigh-ins and self-reports:

• Average weight loss: 16 lbs

• Average waistline reduction: 2.7 inches

• Cycle regularity: Moderately improved

• Overall symptom improvement: 6.2 / 10

Pros

• 7-strain probiotic blend tackles hormonal imbalance through the gut microbiome ⁸

• Omega oil adds a minor anti-inflammatory support ⁹

Cons

• No ingredients to address insulin resistance and androgens

---

#4 — Vita-PCOS Androgen Blocker

Best choice if excess hair, acne, and other androgen-driven symptoms are the main concern

What it is

A targeted anti-androgen supplement combining saw palmetto, zinc, stinging nettle, pine bark extract, and L-amino acids.

How it worked

Testers with the most prominent androgen symptoms noticed significant improvements in excess hair growth, acne, and scalp hair thinning. But with only 25mg of inositol, which is far below a clinically effective dose, and no gut-microbiome or anti-inflammatory mechanism, the formula addressed only one PCOS pillar.

Price: $45.99

Data from weigh-ins and self-reports:

• Average weight loss: 10 lbs

• Average waistline reduction: 1.5 inches

• Cycle regularity: Slightly improved

• Overall symptom improvement: 8.7 / 10

Pros

• Saw palmetto and zinc directly target androgen-driven symptoms ^10,11

• Highly effective for excess hair, acne, and hair thinning

Cons

• Addresses only the androgen pillar of the three PCOS root causes

---

#5 — Theralogix Ovasitol Plus

The gold standard for insulin support, but delivered the weakest overall results

What it is

A targeted supplement that contains a pure 40:1 myo-inositol and D-chiro-inositol.

How it worked

Testers of Ovasitol Plus showed significant improvement in cycle regularity, which was consistent with what the 40:1 inositol ratio delivered in clinical studies. But without other ingredients, weight loss, belly fat reduction, and overall symptom improvements were the weakest of any supplement in this test.

Price: $86.68

Data from weigh-ins and self-reports:

• Average weight loss: 6 lbs

• Average waistline reduction: 0.7 inches

• Cycle regularity: Significantly improved

• Overall symptom improvement: 4.7 / 10

Pros

• Clinically studied 40:1 myo:D-chiro inositol ratio

• NSF certified and physician-recommended

• Significant improvement in cycle regularity

Cons

• Relies solely on inositol

• The most expensive supplement in this test

Final word

Every supplement helped these 60 women manage their PCOS symptoms to some degree — but one of them clearly stood out from the rest during this 4-month test.

Bioma Probiotics delivered an average of 31 lbs lost and 5.2 inches trimmed from the waist, with significant improvements in cycle regularity, acne, hair thinning, and hirsutism.

If you’ve tried contraceptives, metformin, inositol, or even other supplements from this list with no success, Bioma Probiotics is the supplement we’d recommend.
