Formulation Notes

Solgar Food Fermented Koji Iron is different…delivering Ultimine, a unique, patent pending form of slower-release iron.

Koji Fermented iron is made by a natural process where iron is introduced into the Koji material and the iron is actually absorbed and stored by the Koji culture. Through this food-based fermentation, Solgar Koji provides a slower released form of iron that is gentle to the stomach.
