This product delivers 36 mg of elemental **iron** using **Ferrochel** (ferrous bisglycinate), a chelated form that binds iron to the amino acid glycine. Bisglycinate is absorbed through a different pathway than standard iron salts, which means it causes significantly fewer GI side effects like nausea and constipation. At 36 mg, the dose sits in the upper therapeutic range used in clinical studies for addressing deficiency, while staying below the 45 mg tolerable upper limit.

Iron is essential for oxygen transport in your blood, energy metabolism, and cognitive function. If you are deficient or at risk of deficiency -- particularly if you are premenopausal, pregnant, vegan, or a regular endurance athlete -- a dedicated iron supplement at this dose can meaningfully improve fatigue and physical performance. The evidence base for iron supplementation in deficient individuals is strong, backed by numerous RCTs.

One thing to keep in mind: iron absorption improves substantially when taken alongside vitamin C, which converts iron into a more absorbable form. This product does not include vitamin C, so pairing it with a food or supplement source of vitamin C at the same meal can help you get more out of each capsule. The capsule itself is vegan-friendly and the inactive ingredient list is minimal.
