Amino acids are scientifically validated as important contributors to the health and maintenance of the skeletal system. Collagen, the most abundant protein in bone, is composed of amino acids—mainly glycine, proline, and hydroxyproline—and provides the structural matrix for bone mineralization. Several studies have shown that adequate dietary intake of essential amino acids supports bone formation and maintenance. For example, research published in journals such as "Osteoporosis International" and "The Journal of Nutrition" demonstrates that protein malnutrition is associated with decreased bone mass and increased fracture risk, especially in the elderly.

Specific amino acids, such as lysine and arginine, have been shown to enhance calcium absorption and stimulate the production of bone growth factors. Furthermore, amino acids are required for the synthesis of non-collagenous proteins involved in bone structure and function. Clinical trials have indicated that supplementation with amino acids or collagen hydrolysates may improve bone mineral density and reduce bone loss, although the effect size varies and is often more pronounced in populations at risk for osteoporosis.

In summary, there is substantial scientific evidence supporting the role of amino acids in bone health, not only as building blocks for bone proteins but also as modulators of bone metabolism and calcium utilization. Nevertheless, they should be viewed as part of an overall balanced diet, as protein excess or deficiency can both negatively impact skeletal health.
