The ratio is the whole point
40:1 myo to D-chiro is the ratio measured in healthy human plasma and used in the trials. A supplement giving myo-inositol alone, or a flat 1:1, is not the same intervention.

Why we made it
Most inositol supplements sold in India give you myo-inositol alone, or a ratio picked for cost rather than for the body. Firtilo-f is dosed at 1100 mg myo-inositol to 27.8 mg D-chiro-inositol — almost exactly 40:1, the ratio found in healthy human plasma and the one used in the trials people cite when they recommend inositol at all.
Around it sits the rest of what the same literature keeps pointing at: chromium picolinate 200 mcg for glucose handling, a standardised fenugreek extract, and vitamin D3 400 IU, because insufficiency is close to universal among Indian women and it is measured alongside almost every one of these outcomes.
Every quantity is printed on the pack. There is no proprietary blend and nothing hidden behind the word "complex".
Uses
The difference
Four things you can check on any competing label before you decide.
40:1 myo to D-chiro is the ratio measured in healthy human plasma and used in the trials. A supplement giving myo-inositol alone, or a flat 1:1, is not the same intervention.
1100 mg of myo-inositol per tablet is printed on the pack. Check it against any competing label before you decide.
200 mcg of chromium picolinate is 100% RDA, not a token sprinkle added for the ingredient list.
No proprietary blend. Five actives, five printed quantities.

The evidence
Claims we make about this product, with the source alongside each one.
Myo-inositol and D-chiro-inositol in a 40:1 ratio reflects the proportion found in healthy human plasma, and is the ratio used in the clinical work on ovarian function.
Inositol supplementation has been studied for its effect on menstrual regularity and markers of insulin sensitivity in women with PCOS.
Chromium is an essential trace element with an established role in normal macronutrient metabolism; 200 mcg meets 100% of the Indian RDA.
Questions
It is the proportion of myo- to D-chiro-inositol measured in healthy human plasma, and it is the ratio used in the studies that made inositol interesting in the first place. A product giving myo-inositol alone is a different intervention, whatever the total milligrams say.
The published work generally looks at outcomes over three to six months of consistent use. Treat anything faster than that with suspicion, and review it with your doctor.
That is a question for your doctor, who knows your prescription and your bloodwork. Do not add or stop anything on the basis of a product page.
It is formulated around that literature, but the actives are general-purpose. Your doctor is the right person to say whether it fits your situation.
