Buying guide and FAQs
What to compare
Check the type, the ratio between the two forms and the amount per daily serving. Blends often use a 40:1 ratio. Powders are usually dissolved in a drink and can deliver larger amounts, while capsules and gummies are simple to take.
What does 40:1 mean?
It means 40 parts myo-inositol to one part D-chiro inositol. For example, 2,000mg and 50mg per serving.
I have PCOS. Should I ask a doctor?
Yes. Speak to your GP before use, particularly if you take medicines, are trying to conceive or are pregnant.
