When people exercise, 4% to 10% of the body’s calories are provided by the destruction of protein. Therefore, muscles will become fatigued due to “negative nitrogen balance” during exercise, and the effect of exercise will decrease. Soy protein peptides have a small molecular weight and do not need to be digested by the gastrointestinal tract. They can provide nitrogen sources for muscles in a timely manner, thereby reducing or delaying muscle fatigue caused by exercise and improving exercise status. According to SGS testing, the soybean protein peptides produced by Hainan Huayan Collagen contain selenium and are ideal raw materials for sports health nutrition products.
