1, taking too much VC supplement in a short time will produce side effects such as polyuria, diarrhea and rash;

2. Taking excessive VC supplements for a long time may lead to oxalic acid and uric acid stones;

3, children take too much during their growth period, which is prone to bone diseases.

4, a one-time intake of VC2500-5000 mg or more, may lead to a large number of red blood cells rupture, hemolysis and other critical phenomena.

(The above question refers to the traditional acidic vitamin C. If it was acid-free vitamin C, such a thing would not have happened. )

Recently, Austrian scientists have warned that the abuse of vitamin C will weaken human immunity.

Professor Goldberg of the Institute of Medicinal Chemistry of the University of Vienna recently told the press that studies have proved that vitamin C plays an important role in the composition of neurotransmitters such as protein and adrenaline in human connective tissue. When people are infected or have other inflammations, the demand for vitamin C also increases, but we must be very cautious when using large doses of vitamins.

Professor Goldberg warned that increasing the dose of vitamins to more than once a day is not only meaningless, but also likely to backfire. Because there is too much vitamin C around white blood cells, it can not only prevent white blood cells from destroying germs, but also protect germs and cancer cells. Excessive vitamin C can not only enhance human immunity, but also weaken it. Professor Goldberg specially reminded us not to take vitamin C casually like eating jelly beans.

But if you eat more vegetables and fruits rich in vitamins, such as oranges, peppers, tomatoes or potatoes, you don't have to worry about taking too much vitamin C.

Normal adult supplement: vitamin E 30IU.

60% ~ 70% of daily intake will be excreted with excrement. Different from other fat-soluble vitamins, vitamin E has a short storage time in human body, which is the same as vitamins B and C; Medical experts believe that the common oral dose of vitamin E should be 10 to 100 mg each time, 1 3 times a day. Large dose means more than 400 mg per day, and long-term use means continuous use for more than 6 months. Vitamin E contained in the general diet can fully meet the needs of the human body. Therefore, it is not only unnecessary for the elderly to take vitamin E for a long time, but also unsafe and has side effects.

Too much

Is taking a large dose of vitamin E really beneficial and harmless? Robert, an American medical expert, suggested that taking large doses of vitamin E for a long time would cause various diseases. Among them, thrombophlebitis or pulmonary embolism, or both occur at the same time, because large doses of vitamin E can cause platelet aggregation and formation; When blood pressure rises, blood pressure can be reduced or returned to normal after drug withdrawal; Breast hypertrophy can occur in both men and women; Headache, dizziness, dizziness, blurred vision, muscle weakness;

Chapped skin, cheilitis, angular stomatitis, urticaria; Symptoms of diabetes or angina pectoris are obviously aggravated; Hormone metabolism disorder, prothrombin reduction; Blood cholesterol and triglyceride levels increased; Platelets increase, vitality increases, and immune function decreases.

Vitamin e poisoning

Adults take relatively large doses of vitamin E(D-α- tocopherol 400~800mg/d) for several years without obvious damage. Those who take 800~3200mg/d occasionally have muscle weakness, fatigue, vomiting and diarrhea. The most obvious toxic effect of vitamin E > 1000 mg/d is to antagonize and enhance the effect of vitamin K.
