Vitamin E encompasses different chemical compounds which are fat-soluble antioxidants. Some of these compounds also possess anti-cancer properties. It has two forms: tocopherols and tocotrienols. The most commonly found form of Vitamin E is alpha-tocopherol. It offers many benefits including neutralizing free radicals, protecting cells, reducing the blood’s ability to clot, and reducing the risk of some types of cancer
Vitamin E is naturally found in the following foods
Vitamin E is also available in the supplement form.
Vitamin E and Cancer
There are no studies that have reported successful use of Vitamin E as a standalone cancer treatment. It is usually used in combination with other drugs or with chemotherapy or radiotherapy. Here are some benefits:
- It inhibits protein kinase c activity. This, in turn, affects cell proliferation or growth and differentiation.
- Some forms of tocotrienol may also be effective against cancers like breast, pancreatic, prostate, and skin.
- In some animal studies, it was found that vitamin E supplements increased the growth of lung cancer.
- In a study, it was found that alpha-tocopherol along with beta-carotene reduced the incidence of prostate cancer in male smokers by a substantial amount. On the other hand, another study found no decrease of vitamin E on the incidence of lung cancer in male smokers
- Cisplatin neuropathy has severe peripheral neurotoxicity in patients. Vitamin E has a neuroprotective effect against it.
- It may help reduce hot flashes in breast cancer survivors
- Vitamin E is a generic term for multiple natural and synthetic compounds, all of which are antioxidants.
- Vitamin E may reduce side effects of some conventional cancer therapies.
- Vitamin E is included in a number of integrative care cancer protocols.
- No published clinical trials to date describe using vitamin E alone as an anticancer therapy.
- Vitamin E has low toxicity and is usually well tolerated in low doses.
- Vitamin E can cause side effects as well as react with some prescription drugs. Vitamin E is contraindicated in some medical conditions. Caution and medical supervision are advised.
According to many studies, natural foods are the best sources for Vitamin E. If you want to take a supplement instead, then we advise that you consult a physician.
