Micronutrients can be found in many foods. Healthy people might be able to get enough vitamins and minerals from their food. People with HIV or another illness need more micronutrients to help repair and heal cells. Also, many medications can create shortages of different nutrients.
What Are Antioxidants?
Some molecules in the body are in a form called oxidized. These molecules are also called free radicals. They react very easily with other molecules, and can damage cells. High levels of free radicals seem to cause a lot of the damage associated with aging.
Free radicals are produced as part of normal body chemistry. Antioxidants are molecules that can stop free radicals from reacting with other molecules. This limits the damage they do. Several nutrients are antioxidants.
Antioxidants are important for people with HIV, because HIV infection leads to higher levels of free radicals. Also, free radicals can increase the activity of HIV. Higher levels of antioxidants can slow down the virus and help repair some of the damage it does.
How Much Do I Need?
You might think that all you have to do to get enough vitamins and minerals is to take a "one-a-day" multivitamin pill. Unfortunately, it's not that easy. The amounts of micronutrients in many of these pills are based on the Recommended Dietary Allowances (RDAs) set by the U.S. government.
The problem with the RDAs is that they are not the amounts of micronutrients that are needed by people with HIV. Instead, they are the minimum amounts needed to prevent shortages in healthy people. HIV disease and many AIDS medications can use up some nutrients.
One study of people with HIV showed that they needed between 6 and 25 times the RDA of some nutrients! Still, a high potency multivitamin is a good way to get basic micronutrients.
