Taking vitamins after exercise may offset the benefits of exercise. German medical scientists have discovered that after exercise, the body produces free radicals. The right amount of free radicals can help fight and prevent diabetes. Vitamin C, E and other supplements have antioxidant effects, which can inhibit free radicals. If you take vitamin C and E supplements after exercise, the exercise effect will be greatly reduced, especially in patients with type second diabetes.
Some vitamins are antioxidants. Many people believe that antioxidant vitamins can reduce free radicals in the body. Taking antioxidant vitamins can protect body tissues from “oxidative stress”, and free radicals may cause some diseases, such as cancer, heart disease, or aging. However, according to a recent study by the University of Jena in Germany, taking too many antioxidants may do more harm than good.
Dr Mike reisti’s research team at Jena university has found that free radicals can provide positive benefits to the body. Free radicals can increase insulin sensitivity. Insulin sensitivity in type second diabetes is relatively weak, but antioxidant vitamins counteract the benefits of free radicals.
The results showed that there was no immediate change in the number of free radicals in men after taking vitamins C and E. On the other hand, those who did not take antioxidants had higher free radical oxidation pressure. After 4 weeks of intensive exercise training, the researchers found that the insulin sensitivity of the group without antioxidants quickly returned to normal. The group taking antioxidant vitamins had worse metabolism.
Sarah Aldred, a lecturer in sports science at the University of Birmingham in the UK, pointed out that this does not mean that vitamins C and E are harmful to the human body. The focus is on the timing of taking them. Elisabeth weichselbaum, an expert at the British Nutrition Foundation, said antioxidants can indeed protect body cells and help reduce the risk of cancer.
