L-alanyl-L-cystine is a dipeptide composed of alanine and cystine, and it is widely used in some functional beverages that emphasize functions such as enhancing immunity, relieving fatigue, and promoting beauty. The following are some specific types of functional beverages:
· Sports functional beverages: During intense exercise, the human body consumes a large amount of energy and nutrients, leading to a feeling of fatigue. L-alanyl-L-cystine can participate in the metabolic processes of the human body, helping to restore physical strength and relieve fatigue. In addition to common electrolytes and carbohydrates, some sports beverages also add L-alanyl-L-cystine. This helps athletes quickly replenish energy and nutrients, improve their athletic performance, and accelerate post-exercise recovery.
· Immunity-enhancing functional beverages: Cystine in L-alanyl-L-cystine can participate in the synthesis of glutathione, which is an important antioxidant and plays a crucial role in maintaining the normal function of cells and the stability of the immune system. Therefore, in some functional beverages designed to enhance immunity, such as a certain brand of protein powder beverage, L-alanyl-L-cystine is added to help enhance the body's immune defense capabilities and improve the body's resistance to diseases.
· Beauty and skincare functional beverages: Cystine is one of the important components of tissues such as the skin, hair, and nails. It helps maintain the elasticity and luster of the skin and promotes the healthy growth of hair. Some functional beverages that focus on beauty and skincare effects, such as a certain brand of collagen oral liquid, will add L-alanyl-L-cystine. It works synergistically with ingredients like collagen to help improve skin conditions, reduce wrinkles, make the skin smoother and more delicate, and also contribute to the smoothness and luster of the hair.
· Liver-protecting functional beverages: L-alanyl-L-cystine can help the liver detoxify, reduce the burden on the liver, and provide a certain degree of protection for the liver. In some functional beverages aimed at liver health, such as a certain brand of liver-protecting beverage, L-alanyl-L-cystine is added. These beverages are suitable for people who often drink alcohol, stay up late, or have relatively weak liver function, and they help maintain the normal function of the liver.
