Environmental factors, such as UV exposure, air pollutants, tobacco smoke and industrial chemicals like pesticides , are also sources of free radicals 2. Over time, this contributes to aging and the development of diseases, including cancer 3. The main antioxidants that help regulate free radicals in your body are the vitamins A, C, and E and the mineral selenium.

The health detriments associated with taking antioxidant supplements outnumber its potential benefits. Your body naturally produces free radicals as a byproduct of energy metabolism during exercise.

The harder and longer you exercise , the more free radicals your body produces 6. However, several studies have shown that taking antioxidant supplements — specifically vitamins C and E — can interfere with how your body adapts to exercise and even eliminate some of the health benefits associated with exercise 8 , 9 , 10 , Since antioxidants neutralize free radicals, taking antioxidant supplements have been speculated to decrease the risk of developing or dying from cancer Several meta-analyses, however, have shown that taking antioxidant supplements does neither reduce the risk of many types of cancers nor reduce the risk of dying from them once diagnosed, In fact, they may even increase the risk of certain cancers 14 , 15 , 16 , In addition, several meta-analyses have found that beta-carotene supplements, a precursor of vitamin A, increases the risk of bladder cancer, and, in people who smoke, the risk of lung cancer as well 18 , 19 , 20 , The exception is selenium , which may help prevent cancer in people with low levels of the mineral or in people with an elevated risk of cancer.

However, more research is needed before selenium can be recommended for this purpose 16 , 22 , 23 , Vitamin A is important for fetal growth and development, but at high doses, vitamin A supplements can increase the risk of birth defects 25 , Therefore, women who might be or are pregnant should not take high doses of vitamin A supplements These supplements are only recommended for pregnant women in areas where vitamin A deficiency is prevalent, such as in Africa and Southeast Asia 28 , Beta-carotene, the precursor of vitamin A, is not shown to lead to birth defects.

But since taking the supplement long-term is associated with cancer, pregnant women should consult with their physician before taking beta-carotene supplements 30 , Though antioxidant supplements are generally not recommended for a variety of reasons, the antioxidant vitamin C may benefit people with the common cold or those who smoke.

Vitamin C has not been shown to prevent the common cold , but it may reduce its severity and duration. In addition, higher doses may cause stomach upset Similarly, exposure to secondhand smoke also increases vitamin C needs Yet, this additional need for vitamin C can be easily met through diet and without taking antioxidant supplements.

For the most part, the use of antioxidant supplements is discouraged, though the antioxidant vitamin C can benefit people with the common cold or those who smoke. Still, needs can often be met through diet instead of supplements. Getting antioxidants from food rather than supplements is much safer and healthier.

UV radiation itself suppresses the immune system, nicotinamide has been shown to inhibit UV induced immunosuppression, which may also play a role in skin cancer development.

Nicotinamide does not increase the threshold for UV induced sunburn. In a key trial published in the New England Journal of Medicine N Engl J Med ; , patients with a history of non-melanoma skin cancer were treated with nicotinamide at the same dose as found in SpectrumRx for one year or a placebo.

Polypodium leucotomos PL is a tropical fern plant native to Central America and parts of South America. The Mayans even drank it as a tea. Historically, ferns have been used for medicinal purposes since ancient Europe.

Polypodium leucotomos has both antioxidant and anti-inflammatory properties, which may explain its ability to prevent damage caused by excessive sun exposure and its helpfulness in ameliorating certain skin conditions. Extracts have been shown in numerous studies to prevent both UVA- and UVB-induced toxicity and DNA damage through reduction of free radicals.

It is important to note that photoprotection does not imply chemoprevention prevention of skin cancers as no studies on the reduction of skin cancers have been published.

It should also be noted that nothing takes the place of topical sunscreens in protecting you from skin cancer. Milk thistle is a flowering plant that comes from the same family of plants as the daisy. It grows in Mediterranean countries and is used to make natural remedies.

The silymarin in milk thistle can also protect the skin from UV ray damage, particularly when applied topically. Silymarin has been shown to have chemopreventive effects against chemical and photocarcinogenesis in various animal tumor models.

A wide range of in vivo studies support that silymarin possesses antioxidant, anti-inflammatory and immunomodulatory properties which may lead to the prevention of skin cancer in in vivo animal models.

Nat Prod Res. Biochem Pharmacol. The importance of vitamin D has received much press over the last few years. Vitamin D is made in our skin in response to UV radiation. No matter what roles Vitamin D may play in our health, it better obtained through supplements and is no excuse for unhealthy behavior in the sun.
