"40:1 inositol ratio supports menstrual and metabolic health in PCOS"
An umbrella meta-analysis of 18,000 participants found inositol cut gestational diabetes risk by 58% and improved PCOS metabolic markers.

"NSF certified — independently tested and verified"
NSF International certification confirms label accuracy and screens for contaminants. This is a legitimate, rigorous third-party standard.

"Chromium picolinate supports healthy blood sugar and insulin"
Clinical trials at 200-500mcg/day show modest but real improvements in insulin sensitivity and lipids in metabolic syndrome and PCOS patients.

"Alpha-lactalbumin increases myo-inositol absorption"
The absorption-enhancement claim is based on limited research. No large human RCT confirms this specific benefit for inositol uptake.

Consumer advice
If you have PCOS or insulin resistance and haven't tried inositol yet, start with the original Ovasitol (cheaper) before upgrading to Plus. If you've tried plain inositol without results, the Plus version's added chromium picolinate and vitamin D3 are legitimate additions with real metabolic evidence. The NSF certification is a genuine quality signal — this is not a fly-by-night brand. Stop taking it once pregnant (as the label correctly advises) and switch to the original Ovasitol. If you're on blood sugar medication, consult your doctor before use as chromium picolinate can have additive effects.

Why the chain breaks for this product
Most ingredients below have real research behind them. The problem isn't the ingredients — it's the doses. 2 of 5 are dosed below what the studies actually used, so the product can claim the benefits without delivering the chain that gets you there.
Natural compound that supports insulin sensitivity and hormone balance, especially in PCOS and pregnancy.
Research-backed dose: 2-4 g daily based on study doses
In this product: 2000 mg
Effective at 1 serving/day, as the label directs.
Insulin-sensitizing compound studied for PCOS. Best used in combo with myo-inositol. High doses may backfire.
Research-backed dose: 150-600 mg daily (typically combined with myo-inositol at 40:1 ratio); high doses (2400 mg) associated with adverse hormonal effects
In this product: 50 mg
Underdosed: even at the label's max 2 servings/day, it falls short of the research-backed dose.
Whey protein fraction found in breast milk. Limited evidence for immune or sleep benefits in adults.
In this product: 50 mg
Trace mineral shown to modestly improve blood sugar control and insulin sensitivity in metabolic conditions.
Research-backed dose: 400 mcg daily based on study doses
In this product: 100 mcg
Underdosed: even at the label's max 2 servings/day, it falls short of the research-backed dose.
Vitamin D3
Essential fat-soluble vitamin. Supports bone health, immune function, and may improve exercise tolerance in deficient individuals.
Research-backed dose: 400–80,000 IU daily depending on condition and deficiency status
In this product: 12.5 mcg (500 IU)
Safety & side effects
What NIH says about the ingredients in this product. This describes the ingredients, not tests of this product, and it is not medical advice. Ask a doctor or pharmacist first if you take medication, are pregnant or nursing, or have a health condition.
Chromium
The FNB found no adverse effects linked to high chromium intakes from food or supplements, so it set no UL. It still said caution may be warranted because the data are limited.
Serious risks
- Isolated case reports link chromium supplements to several problems, including liver dysfunction and renal failure.
- The FNB said caution may be warranted because data are limited, and high intakes could have adverse effects.
Avoid or ask a doctor first if
- People with renal or liver disease might be susceptible to adverse effects from high chromium intakes.
Medication interactions
- Several types of medications have the potential to interact with chromium supplements.
- People taking medications regularly should talk with their health care providers about their chromium intakes.

Vitamin D
Vitamin D toxicity is almost always caused by excessive supplement intake. It can raise blood calcium and, in extreme cases, lead to kidney failure and death. The adult upper limit is 100 mcg (4,000 IU) a day.
Possible side effects
- High blood calcium from vitamin D toxicity can lead to nausea, vomiting, muscle weakness, and other symptoms.
Serious risks
- Toxicity can cause high blood and urine calcium. In extreme cases it may lead to kidney failure, soft tissue calcification, heart rhythm problems, and death.
- Toxicity is almost always caused by taking too much vitamin D through supplements.
Avoid or ask a doctor first if
- The source says people on regular medications should talk with their health care providers about vitamin D intake and status.
Medication interactions
- Vitamin D supplements may interact with orlistat, statins, steroids, and thiazide diuretics.
- Taking calcium supplements with vitamin D supplements may raise the risk of certain adverse effects.
Upper limit: 100 mcg a day for adults 19+. This label lists 12.5 mcg (500 IU).
