Application:
Nutritional Supplement: Calcium citrate is a popular source of calcium for dietary supplements. It is easily absorbed by the human body compared to some other forms of calcium. For example, in the production of calcium - fortified cereals, calcium citrate is added to increase the calcium content. When people consume these cereals, they can obtain a significant amount of calcium to meet their daily nutritional requirements.
Food Additive: It can be used as a food additive to provide a tart flavor. In the preparation of some beverages like lemon - flavored drinks, a small amount of calcium citrate can be added to enhance the sour taste. It also helps to stabilize the pH of the food products. In the case of some dairy products such as cheese, it can help to control the acidity level during the production process, which is important for the texture and flavor development of the cheese.
Skin Care Products: Calcium citrate can be found in some skin care products. It is believed to have benefits for the skin. For example, in some anti - aging creams, it may help to improve the skin's elasticity. Calcium is an essential mineral for maintaining healthy skin cells. It is involved in the process of cell division and renewal. When applied topically in the form of calcium citrate - containing products, it can potentially promote the growth of new skin cells and help to reduce the appearance of fine lines and wrinkles.
Hair Care Products: In hair care products like shampoos and conditioners, calcium citrate can be used to provide calcium to the hair and scalp. It is thought to help strengthen hair follicles. For example, in a shampoo specifically designed for hair growth, calcium citrate may be one of the ingredients that contribute to a healthier scalp environment, which in turn can support stronger and possibly faster - growing hair.
