What it is

Ergosterol (Mushroom Sterol) is a sterol & vitamin d supplement. Ergosterol is the principal sterol of fungal membranes and the provitamin from which mushroom vitamin D2 is made on UV exposure. Used in adult dosing protocols in India and internationally, it is sold as a single-ingredient supplement.

How it works

UV-exposed ergosterol converts to vitamin D2 (ergocalciferol), supporting calcium and immune function, while ergosterol and its peroxides have immune-modulating activity. Effects are dose-dependent and typically measurable within 4-8 weeks.

Who should take it

Adults seeking a mushroom-derived vitamin-D precursor and immune support.

Avoid / careful

Vitamin D2 is less potent than D3 for raising blood levels — D3 is preferred if correcting deficiency. Generally well tolerated.

FAQs

Frequently asked

Is ergosterol the same as vitamin D2?
No, ergosterol is the precursor to vitamin D2. It converts into vitamin D2 (ergocalciferol) when exposed to UV light.
Can ergosterol be obtained from food?
Ergosterol is found in mushrooms and yeasts. However, dietary intake alone is usually insufficient for optimal vitamin D status.
How long does it take for ergosterol to convert to vitamin D2?
The conversion process requires UV light exposure. Once converted, the resulting vitamin D2 takes approximately 4-8 weeks to measurably impact blood levels and immune markers.
