Inositol as powder or capsules – which is better?

In terms of content, there's no difference – it's the same substance. The difference lies in the amount you're supposed to take every day.

The math

The usual daily amount is around 4 grams of myo-inositol plus 100 mg of D-chiro-inositol. A large capsule holds about 500 to 600 mg depending on the fill. That works out to six to eight capsules a day. As a powder, the same amount is one level scoop, once a day.

Why this matters in practice

Inositol is taken over months. What seems doable at the start decides, eight weeks in, whether you're still taking it at all. There's a reason the FAQ of some capsule brands includes the question of whether you can open the capsules and stir the powder into water.

When capsules make sense

On the go or when traveling, capsules are more convenient because there's nothing to measure or mix. If you take your daily dose at home, powder is usually the easier option.

What to look for in both forms

What matters is the actual amount per serving and the ratio of the two inositol forms. Some products list a total amount without showing the split between myo and D-chiro.
