Many people living with HIV take vitamin and mineral supplements, hoping to boost their immune system and improve general health.

Taking high doses of individual vitamins and minerals is not recommended as they might become toxic, especially Vitamins A, C, E, B6, Zinc and Selenium. Herbal remedies are also widely used by people with HIV. However, large doses of herbal supplements such as garlic, African potatoes (Hypoxis), Sutherlandia and St. John's wort, might interact with some antiretroviral drugs and hence reduce the effectiveness of those drugs. Although dietary supplements might be beneficial in some instances, it is best to consult your GP or dietitian before you start taking them.
