Vitamins

Vitamins are a class of organic compounds that cannot be synthesized by the human body, but are important for maintaining normal physiological functions. Vitamins play a role in regulating metabolism, promoting growth and development, and enhancing immunity in the human body. According to their solubility, vitamins can be divided into water-soluble vitamins and fat-soluble vitamins.

Water-soluble vitamins include vitamin C and vitamin B group (such as vitamin B1, B2, B3, B5, B6, B7, B9, B12, etc.). Water-soluble vitamins are not easy to store in the body, and most of them need to be supplemented through diet every day.

Fat-soluble vitamins include vitamin A, vitamin D, vitamin E, and vitamin K. Fat-soluble vitamins can be stored in adipose tissue, so compared with water-soluble vitamins, the body stores a larger amount and does not need to be taken every day. However, excessive intake of fat-soluble vitamins can lead to toxicity.

Different vitamins have different functions in the human body. For example, vitamin C is involved in collagen synthesis, vitamin A is involved in visual processes, and vitamin D is involved in calcium absorption and bone health. Therefore, maintaining a balanced diet and taking in various vitamins is one of the important factors for maintaining health.
