Free radicals can cause unwanted damage to cells in your body if their levels are too high. This can negatively affect your immune system, leaving you prone to illnesses such as heart disease, diabetes and cancer, all of which can increase your risk of contracting COVID-19. One way to reduce free radical presence in your body is by taking various antioxidants. Antioxidants help prevent or slow down cell damage caused by free radicals while indirectly aiding in immune function.

One of these antioxidants is vitamin E, a vitamin that dissolves in fat. This means that it can be stored in your body and used when needed. Like other antioxidants, it is found in many foods such as fruits, vegetables and meat, and is also available as a supplement. Without further ado, here are the best vitamin E supplements to boost your immune system during the coronavirus pandemic:
