In the process of exercise, the human body needs more energy, and the intake and consumption of oxygen increase, which leads to an increase in the proportion of free radicals in the body, sometimes even reaching four times of the normal state. At this time, the body can only destroy excess free radicals by consuming a lot of antioxidant VE.
After high-intensity exercise, add VE appropriately. VE can also relieve muscle soreness, prevent chronic diseases and prevent aging of body organs.

The following people are not suitable for vitamin supplementation.
1, psoriasis: Avoid vitamin A. Retinol, a conventional drug for psoriasis, is a derivative of vitamin A and will be stored in the liver after entering the body. Excessive use (more than 0.7 mg per day for men and 0.6 mg per day for women) will produce toxins in the body, leading to conjunctivitis, alopecia and skin diseases.
2, heart disease: do not supplement vitamin E and potassium. A 7-year large-scale study involving 65,438+0,000 heart patients at McMaster University in Canada found that a large dose of vitamin E supplementation (400 international units per day, equivalent to 363 mg) would increase the risk of heart failure and hospitalization after onset by 65,438+03% and 20% respectively. Excessive potassium supplementation (more than 3500 mg per day) will increase the risk of palpitation and arrhythmia.
3. Diabetes: Avoid vitamin B3. A large amount of vitamin B3 supplementation (more than 17 mg for men and more than 13 mg for women) will lead to an increase in blood sugar. The larger the supplementary dose, the more serious the blood sugar problem will be.
4. Osteoporosis: Avoid vitamin A and phosphorus. Excessive blood phosphorus level (the supplement amount exceeds 1000mg/ day) will lead to bone calcium loss and aggravate the risk of osteoporosis. British health guidelines suggest that phosphorus supplementation should not exceed 250 mg per day. High-dose vitamin A supplementation is closely related to the decrease of bone mineral density.
Vitamin A supplementation exceeding 1.5 mg per day increases the risk of bone mineral density reduction by 6%- 14%. At present, the recommended daily intake of vitamin A for men and women is 0.7 mg and 0.6 mg respectively.
5, gastric ulcer: avoid vitamin A research found that taking drugs for gastric ulcer while supplementing vitamin A will seriously weaken the curative effect of the latter.
In addition to vitamins, patients with kidney disease and prostate cancer had better not supplement calcium. Two common causes of kidney disease are hypertension and diabetes. Supplementing calcium more than 700 mg per day (recommended daily amount) will lead to calcium accumulation in kidneys, and long-term calcium supplementation will lead to kidney calculi.
At the same time, Wake Forest Baptist Medical Research Center found that the loss of bone minerals was more serious in patients with prostate cancer who supplemented 500- 1000 mg of calcium every day. Exercise is an effective way to strengthen bone strength.
