Vitamins are essential nutrients for our body, and its role is very extensive, and it has many benefits to the human body. However, many people have some misunderstandings about vitamins, of which the following are the most common ones. 1. Prevent colds Foreign experts believe that if there is a lack of vitamin C, it may protect the occurrence of bleeding gums, decreased resistance and so on. Vitamin C can promote the synthesis of immune proteins, increase the activity of the body's functional enzymes, and increase the number of lymphocytes and increase the phagocytic activity of neutrophils. Therefore, there are so many people propose that as soon as possible to take large doses of vitamin c to prevent cold theory. However, a recent study found that vitamin C does not actually cause vitamin C. Those who take 2 grams of vitamin C per day have the same chance of developing a cold as those who only take placebo. In fact, for ordinary people, taking vitamin C to prevent colds has no effect. It is completely unnecessary to take large amounts of vitamin c in order to prevent colds. 2. Long-term consumption For the prevention of colds, it was also pointed out that adults take 1 gram of vitamin C daily to prevent colds. If the daily dose of vitamin C is less than one gram, it will not have a preventive effect. This is not the case. If long-term excessive use of vitamin C can cause nausea, vomiting, diarrhea, abdominal pain, skin rashes and other symptoms, if serious, it can lead to urinary stones, deep vein thrombosis, intravascular hemolysis or coagulation and other symptoms. Experts suggest that vitamin c supplementation should not exceed 3 grams per day, which can lead to hemolysis and can be fatal in severe cases. 3. Same as eating fruits and vegetables Most of the vitamin C we take is a synthetic product. Although the vitamins in the vitamin tablets are structurally the same as those in fruits, the effects are completely different. Natural vitamins are more effective and more stable and reliable because of their compatibility and protection with other natural ingredients. However, vitamin tablets are not necessarily. If they are not properly preserved, they may even produce harmful degradation products. Although vitamin c is a nutritional supplement, it can cause great harm to the body if it is not taken scientifically.
