Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Amino acid chelates are mineral supplements in which minerals (such as iron, zinc, magnesium, and calcium) are bound to amino acids to enhance absorption in the body. Their use in bodybuilding is primarily justified by scientific rationale rather than tradition, although the direct evidence supporting significant benefits specifically for bodybuilding is limited and mixed. The main scientific basis is that minerals are essential for muscle function, energy production, and recovery. For example, magnesium is crucial for muscle contraction and recovery, and zinc plays a role in testosterone synthesis and immune function. Chelation is thought to improve the bioavailability of these minerals compared to inorganic salts, potentially leading to better outcomes for athletes with increased mineral requirements. However, robust clinical trials directly linking amino acid chelate supplementation to enhanced muscle growth, strength, or athletic performance in healthy, well-nourished individuals are lacking. Most studies focus on correcting deficiencies rather than providing additional benefits to those who already meet their mineral needs through diet. Consequently, while it is scientifically plausible that amino acid chelates can support bodybuilding by preventing deficiencies and optimizing mineral status, the evidence for performance enhancement is currently modest (rated 2 out of 5). Supplementation may benefit those with documented deficiencies or increased needs due to intense exercise, but routine use in all bodybuilders is not strongly supported by current research.
