Iron Bisglycinate

Gentler iron for people who actually need iron.

Iron fixes iron-deficiency anemia. It does not fix “feeling tired” in people with high ferritin. Bisglycinate is often easier on the stomach than sulfate. Get a ferritin and CBC before you play pharmacist.

How to use

Only if labs say so. Often 18–25 mg elemental, every other day, away from coffee and calcium.
