Is it really useful to supplement vitamin C and E to prevent prostate cancer?

As a kind of organic substance necessary for maintaining life, the role of vitamins has long been discovered and used by medicine, and it has become a consensus in the medical community that excessive intake of vitamins A and D is toxic. However, several other vitamins with antioxidant effects, including vitamins B, C, E, carotene-convertible vitamin A, etc., are generally considered to have very low toxicity, and large doses of vitamins C and E have been used clinically for many years.

The latest research shows that vitamin C has a counter-effect on cancer treatment, while vitamin E can cause prostate cancer!

Vitamin C not only has no significant effect on inhibiting the spread of cancer cells, but also accelerates the spread of cancer cells. A clinical trial on vitamin C showed that the spread of cancer cells in 15,000 cancer patients was not inhibited. The New York Cancer Research Center also came to the same conclusion that vitamin C can repair cancer cells that are about to die during radiotherapy. The center's laboratory research found that mice with tumors in their bodies, the mice injected with vitamin C, had tumors that spread much faster than mice that were not injected.

The use of vitamin E can cause prostate cancer in men and increase the possibility of recurrence of cancer in other parts of the body. Johns Hopkins School of Medicine in the United States conducted a survey of 135,000 healthy people and found that taking large doses of vitamin E increased the probability of sudden death by 4%. Taking vitamin E with other types of vitamins or mineral elements will increase the mortality rate by 6%. Long-term use of vitamin E increases the probability of heart failure by 13%. A study of 540 people with brain cancer and neck cancer published in the American Journal of Clinical Oncology showed that after radiotherapy for these cancers, although vitamin E reduced the side effects of radiotherapy, the recurrence rate of cancer was higher.

In fact, for most people, the vitamins they take in through food every day can basically meet the needs of the human body, and there is no need for additional supplements. Especially for cancer patients, the rational use of vitamins is even more important.
