What is Inositol?

Inositol is a molecule that is very similar to glucose in terms of structure. It has some potential health benefits that have not been widely studied.

Things to Look for in a Good Inositol Supplement

The amount of inositol per capsule is something to look out for when shopping for an inositol supplement. Another thing to be mindful of is the fact that there are nine isomers of inositol, and which one you choose will depend on why you want the inositol.

The most common one is myo-inositol, and most supplements just labeled “inositol” contain this isomer. Another fairly common isomer is d-chiro inositol. Another consideration when purchasing your supplement is what form you want. Bulk powders tend to be cheaper, while capsules are more convenient. Occasionally, a manufacturer will offer an unusual form, like a chew, soft gel tablets, or a drink mix.

How to Take Inositol

Most experts recommend taking a single dose before breakfast. This dose is generally between 200 and 4000mg.

It is important to note that if you take softgels, the mho-inositol in these formulations is more bioavailable, and you will only need to take 30% of the recommended dosage to get the same effect.
