You're getting 25 mg of **iron** in the bisglycinate form, where the iron is bonded to the amino acid glycine. Bisglycinate is absorbed through a different intestinal pathway than standard iron salts like ferrous sulfate or fumarate, which means significantly less stomach upset, nausea, and constipation. At 25 mg, the dose falls squarely in the clinical maintenance range (15-25 mg) used in studies for preventing and correcting deficiency, while staying well below the 45 mg tolerable upper limit.

Your body needs iron to carry oxygen through the bloodstream, produce cellular energy, and support cognitive function. If you are at higher risk of deficiency -- premenopausal, pregnant, following a plant-based diet, or training heavily in endurance sports -- a dedicated iron supplement at this dose can make a real difference in fatigue and physical performance. The evidence for iron supplementation in deficient individuals is strong across multiple well-designed clinical trials.

This product does not contain vitamin C, which is worth noting because vitamin C meaningfully increases iron absorption by converting it into a more readily absorbed form. Taking your tablet alongside a vitamin C source -- an orange, bell pepper, or a separate supplement -- can help you absorb more from each dose. The tablet is suitable for vegans and vegetarians, and the excipient list is straightforward with no unnecessary additions.
