Start your day with confidence—Thorne’s Iron Bisglycinate is crafted to help you feel your best. Iron contributes to normal cognitive function and energy-yielding metabolism, so you can stay sharp and keep up with life’s demands. It also supports the normal formation of red blood cells and haemoglobin, helping your body transport oxygen efficiently. With a chelated form for optimal absorption and fewer digestive side effects, this NSF Certified for Sport® supplement is trusted by athletes and anyone seeking reliable, everyday support. Iron also contributes to the reduction of tiredness and fatigue, so you can feel ready for whatever comes next.

Thorne’s Iron Bisglycinate is a smarter choice for iron supplementation because it tackles the common issues of poor absorption and digestive discomfort head-on. Traditional iron supplements, like ferrous sulphate, can cause unpleasant side effects—nausea, constipation, and more—due to their difficulty being absorbed by the body. Thorne’s formula combines iron with glycine to enhance absorption and drastically reduce these side effects. Plus, with NSF Certified for Sport® certification, Thorne’s Iron Bisglycinate guarantees top-tier quality, purity, and safety, making it a reliable option for athletes and anyone needing effective, gentle iron support.

Thorne sets the standard for excellence in the supplement industry. Recommended by over 100 professional sports teams and U.S. National Teams, Thorne offers a curated bundle of clean, science-backed supplements and treats designed to fuel your body naturally and effectively. With more than 30 years of dedication to quality, Thorne's commitment to purity and potency begins with sustainably sourced ingredients and rigorous testing.
