THORNE Iron Bisglycinate delivers 25 mg of elemental iron in a highly absorbable bisglycinate form, specifically designed to minimize common gastrointestinal discomfort often associated with iron supplements. The chelated structure allows iron to pass through the digestive system without causing irritation, making it suitable for individuals with sensitive stomachs or those new to iron supplementation. This formulation does not require stomach acid for absorption, enhancing bioavailability and reducing the likelihood of nausea or constipation. Each serving provides a consistent dose that supports healthy red blood cell production, oxygen transport, and overall energy metabolism. The product is certified NSF Certified for Sport, indicating it has been rigorously tested for banned substances and meets strict quality and purity standards. This certification is especially valuable for athletes or anyone concerned about supplement integrity.

Additionally, THORNE Iron Bisglycinate is gluten-free, dairy-free, and made without artificial additives or common allergens. The 60-serving bottle offers a 60-day supply at the recommended dosage, providing a convenient and long-lasting option for maintaining optimal iron levels. Iron bisglycinate itself is recognized for its gentle nature on the digestive tract while still delivering effective results. Unlike traditional iron salts such as ferrous sulfate, the bisglycinate form is bound to the amino acid glycine, which enhances absorption and reduces the risk of oxidative stress. This makes it an excellent choice for individuals with mild to moderate iron deficiency, as well as those with increased iron needs due to diet, activity level, or lifecycle stages such as menstruation or pregnancy. The formula is designed to work synergistically with the body’s natural processes, offering a non-constipating alternative to standard iron supplements. The supplement is manufactured in a facility that adheres to strict quality control measures, ensuring consistent potency and purity. THORNE’s commitment to evidence-based ingredients and third-party testing adds an extra layer of reliability. Each batch undergoes thorough analysis to confirm that the product meets label claims and is free from contaminants. This attention to detail makes the supplement a trusted option for healthcare professionals and consumers seeking a high-quality iron source. With a price point that reflects excellent value for a premium NSF-certified product, THORNE Iron Bisglycinate combines efficacy, safety, and affordability. The compact bottle is easy to store and travel with, and the capsules are simple to swallow. Whether used to address a deficiency, support athletic performance, or maintain general wellness, this supplement offers a practical solution for meeting daily iron requirements without the typical side effects.
