Inositol

Whole-food / Other -- also: myo-inositol, D-chiro-inositol, inositol hexaphosphate

One ingredient, seen the whole way through: what it is, how it works, the honest evidence, the form that matters, the systems it touches, and the studies behind it.

How it works

  • Sense -- inositol phosphoglycans act as second messengers downstream of the insulin receptor, the mechanism behind inositol's study in insulin signalling

  • Build -- myo-inositol is a structural precursor to phosphatidylinositol, a membrane phospholipid and the substrate for the PI3K signalling pathway

  • Exchange -- myo-inositol and D-chiro-inositol interconvert via an epimerase, and the ratio between them differs by tissue, which is why studies specify the form

  • Regulate -- studied in ovarian function, where the largest body of randomized evidence sits, typically at gram-level doses over months

Form matters

The same nutrient can be made in very different forms -- and a study done on one form does not automatically apply to another. Methylcobalamin is not cyanocobalamin; magnesium glycinate is not magnesium oxide; a whole-food extract is not the synthetic isolate that was studied. Two things decide whether what is in the bottle behaves like the research: the exact form, and independent lab verification (a Certificate of Analysis) that the form and dose on the label are truly what is inside. Without a COA, you are trusting a label, not the science.
