Functions and Mechanism of Action
Iron is an important component of hemoglobin in red blood cells and myoglobin in muscle cells where it is required for oxygen and carbon dioxide transport. Optimal iron levels of at least 20-25 ng/mL have been associated with athletic performance, muscle strength and mitochondrial function.
In a clinical trial involving iron-depleted (serum ferritin <20 μg/L) individuals, six weeks of supplementation with 20 mg of iron per iron day improved iron status by enhancing serum iron. Iron supplementation also improved muscle fatigue of the quadriceps femoris muscle group, which may support physical performance.

Klean Athlete’s Iron provides 27mg of elemental iron per tablet in the form of iron carbonyl, which has properties to allow for high absorption in the gastrointestinal tract, thus helping to decrease the typical gastrointestinal side effects.
