Another type of alternative therapy for treating HIV is micronutrient supplementation. Micronutrients are vitamins and minerals, so these supplements would be in the form of a general daily multivitamin. These supplements have been proven to help treat HIV because HIV can cause micronutrient deficiencies, so the supplements can help replenish these needed vitamins and minerals. Although the supplements may not help ease all negative symptoms, they offer some benefits and are safe for HIV-infected patients. Supplements are also safe for HIV-infected pregnant women and their children. Specifically, vitamin A and zinc have shown positive health effects. There are no major negative side effects of vitamin and mineral supplements.
