Daily supplementation is recommended if your ferritin is below 35 ng/mL. Athletes need 1.5x more iron than non-athletes due to training-induced losses. Get your ferritin tested every 8-12 weeks to monitor levels and adjust supplementation accordingly.

Iron bisglycinate is elemental iron bonded to the amino acid glycine. This chelated form is absorbed 4-5x more efficiently than ferrous sulfate (drugstore iron) and doesn't cause the constipation, nausea, or stomach upset common with traditional iron supplements. Your gut recognizes the glycine carrier and absorbs it readily.

Absolutely. Vegetarian and vegan athletes have iron needs up to 1.8x higher than omnivores because plant-based iron (non-heme) is absorbed less efficiently. This chelated iron bisglycinate provides the bioavailable elemental iron your body needs without relying on dietary heme iron from meat.
