Boost muscle mass

Collagen is an important component of skeletal muscle because it is the most abundant protein in the body. Collagen supplements may help people with sarcopenia, or the loss of muscle mass that occurs with age, according to research.

In a 12-week study, 27 men with this condition were given 15 grams of collagen while engaging in daily exercise. They gained significantly more muscle mass and strength than men who exercised but did not take collagen. Supplemental collagen, according to researchers, may promote the synthesis of muscle proteins such as creatine, as well as stimulate muscle growth after exercise.

However, collagen protein is not more effective than whey protein in terms of muscle or strength building. This is because, unlike whey protein, collagen is deficient in essential amino acids, particularly leucine, which is essential for muscle growth. More research is needed to investigate collagen's ability to increase muscle mass.
