Vitamins That Support Immune Function
Vitamins D, C, and E, plus zinc and selenium, and how they support immune function in autoimmune conditions.
There are no easy or quick fixes, but many vitamins play a role in overall immune function. In autoimmune disease, some vitamins can have an especially meaningful effect.
Vitamin D. Studies show an association between vitamin D deficiency and both lupus and rheumatoid arthritis. Vitamin D is fat-soluble and helps regulate the immune system, including the T cells (or 'killer cells') that fight infection, while lowering inflammation.
Vitamin C. Foods like tangerines, bell peppers, lemons, limes, spinach, kale, Brussels sprouts, and strawberries are excellent sources.
Vitamin E. A powerful antioxidant found in spinach, broccoli, almonds, sunflower seeds, and peanuts.
Other important nutrients: iron, zinc, folate, and selenium all contribute to healthy immune function and may help control inflammation. Since evidence does not yet support broad vitamin supplementation for preventing or treating autoimmune disease, incorporating these vitamins and minerals through diet is a great starting point. Don't forget sleep and exercise too.
