Do you have PCOS? I googled the main ingredient and I guess it's a new thing for PCOS. I've never heard of it before now.
It's not new. Someone is cashing in on those that don't realize you can buy folic acid and myo-inositiol separately for far cheaper than what they offer. And if you don't take them with the rest of the B vitamins (which is all they are) you will have pretty much zero effect. B vitamins work best with taken together and in the proper ratio.
Myo-inositol is found in fruits, nuts, and beans. A deficiency can contribute to insult resistance. There are allegedly other benefits, but all supplements make lots of claims. There is really no reason to spend $35 on something you can get for $10 without the stupid name.
