Rating (out of 5): 4

Protein is scientifically validated as an essential nutrient for supporting the skin body system. The skin is primarily composed of structural proteins such as collagen and elastin, which provide strength, elasticity, and resilience. Dietary protein supplies the amino acids necessary for the synthesis and repair of these proteins. Several studies have demonstrated that adequate protein intake is crucial for maintaining skin integrity, wound healing, and recovery from injuries. Protein deficiency can lead to symptoms such as dry, flaky skin, delayed wound healing, and increased susceptibility to skin infections. Specific amino acids, such as proline and glycine, are directly involved in collagen synthesis, while others contribute to the formation of enzymes and other molecules important for skin health. Clinical research also supports the use of protein supplementation in populations at risk of malnutrition to improve skin outcomes. Overall, the role of protein in skin health is well-established and supported by a substantial body of scientific literature.
