Thorne Iron Bisglycinate Capsules - Gentle & Highly Absorbable

Superior Absorption & Bioavailability: Iron bisglycinate is a chelated form where iron is bound to two glycine molecules, creating a stable structure that passes intact through the stomach and is absorbed efficiently in the small intestine. This molecular design bypasses the competitive absorption pathways that reduce uptake of non-chelated iron forms, resulting in significantly higher bioavailability while minimizing oxidative stress in the gastrointestinal tract.

Gentle on Digestion: Unlike ferrous sulfate and other conventional iron salts that commonly cause nausea, constipation, and stomach upset, bisglycinate chelation protects the iron from reacting with other dietary components. This prevents the formation of free radicals in the gut that trigger inflammation and discomfort, making Thorne's formula exceptionally well-tolerated even for those with sensitive digestive systems or inflammatory bowel conditions.

Energy Production & Oxygen Transport: Iron serves as the central component of hemoglobin in red blood cells, enabling efficient oxygen delivery from lungs to tissues throughout the body. Adequate iron status supports mitochondrial function and ATP synthesis, directly combating fatigue and supporting physical performance, cognitive function, and metabolic efficiency during periods of increased demand or deficiency.

Clean Formula & Optimal Dosing: Thorne's 25mg elemental iron provides therapeutic support without excessive dosing that can cause oxidative damage. The formulation contains no gluten, dairy, soy, or artificial additives, and the bisglycinate form won't interfere with the absorption of calcium, zinc, or other essential minerals when taken as directed, making it compatible with comprehensive supplementation protocols.
