**Ferrochel Iron Bisglycinate** at 25mg per capsule puts you right at the top of the maintenance range (15–25mg) used in clinical research for preventing deficiency and supporting energy levels. This is the bisglycinate chelate form, which absorbs 2–4x better than standard iron salts and is significantly easier on your stomach — meaning you're getting more usable iron per milligram.

At 25mg, you're well-dosed for maintaining healthy iron stores, supporting oxygen transport to muscles and brain, and sustaining energy production. If you're addressing a diagnosed deficiency, your practitioner may recommend a higher dose in the 25–45mg range.

One important note: iron is one of the few supplements you should test before taking. Get your ferritin levels checked first — supplementing when you're not deficient can lead to iron overload, which causes its own health problems. Pairing with vitamin C at meals will boost absorption further.
