Indeed, vitamins are very important to the human body, as they are involved in the composition of various functional enzymes in the body and are indispensable for maintaining normal physiological functions of the body, and are also very meaningful for improving certain skin conditions. For example, vitamins C and E mentioned by Xiao Li are very important antioxidants that can help fight against oxygen free radical damage to the skin and slow down the aging process, and they, along with beta-carotene and vitamin B3, are very important substances that protect the skin from UV damage. In addition, vitamin A can maintain the normal structure and function of the epidermis, and its deficiency can lead to rough skin, hair follicle keratinization, nail dystrophy and other conditions; vitamin B2 deficiency can cause lip inflammation and keratitis; vitamin D deficiency can cause osteoporosis, etc. Therefore, we need to ensure adequate intake of all kinds of vitamins in our daily life. Vitamin E is abundant in milk, eggs, meat and vegetable oils; vitamin C is abundant in fresh vegetables and fruits; vitamin A is present in animal liver, milk, eggs and fish eggs; vitamin B is abundant in cereals and beans, and so on. Therefore, normal people should still get vitamins mainly from food, as long as a balanced diet, eating a variety of food, generally can get the amount of vitamins physiological needs. For special groups of people, such as pregnant women, growing children, and elderly people with reduced gastrointestinal absorption, due to the increased demand for vitamins, some supplemental vitamin tablets designed specifically for them can be used according to the situation. In medical work, we use some vitamins to treat certain skin diseases, such as the application of vitamins C and E for skin melanosis; beta-carotene, vitamin B3 for photosensitive skin diseases; and vitamin A for hyperkeratotic skin diseases such as ichthyosis, etc. However, all treatments must be under the observation and guidance of a doctor, as vitamin overdose can also be harmful accordingly. Vitamin C overdose, besides being irritating to the gastrointestinal tract, also tends to cause urinary tract stones. As vitamin C has a strong inhibitory effect on melanin synthesis, vitiligo patients need to consume less. The actual fact is that you will be able to get a lot more than just a few of the most effective and most effective products. The actual fact is that you will find a lot of people who are not able to get a good deal on this kind of things. Therefore, vitamin taking is definitely not more than good, “CE complex” is not as Xiao Li think has a “big tonic special” role.
