Thorne - Iron Bisglycinate

Why We Love It

Iron levels matter, especially when training volume climbs or fatigue starts to linger longer than it should. Thorne Iron Bisglycinate is a reliable option for endurance athletes who need to support oxygen delivery and maintain consistent energy without upsetting their gut. It is well suited to runners, cyclists, and triathletes managing heavy loads, dietary restrictions, or known low iron status, helping you train and race with confidence when iron demands are higher.

 

Talk Nerdy To Me

Thorne Iron Bisglycinate provides 25mg of elemental iron per capsule in the form of Ferrochel® iron bisglycinate, a chelated compound designed for improved absorption and tolerance. By binding iron to the amino acid glycine, this form is gentler on the gastrointestinal tract compared to traditional iron salts like ferrous sulfate. Iron plays a key role in red blood cell formation and oxygen transport, which is critical for endurance performance. This formula is NSF Certified for Sport®, with every batch tested to verify label accuracy and absence of banned substances.
