HIV: What to Know About Taking Vitamins and Supplements

Medically Reviewed by Brunilda Nazario, MD on April 28, 2021

Your body needs vitamins and other essential nutrients in order to work properly. Eating a variety of foods can help you get the nutrients you need. This also has the added benefit of adding fiber and antioxidants to your diet.

There’s evidence that some supplements may be beneficial for people with HIV. But some may be especially risky if you have the disease. And too much of almost anything can be dangerous.

Here’s what you need to know.


Some research has found that women with HIV who take a daily multivitamin are about half as likely to go on to develop AIDS as those who don’t take one. The multivitamin that researchers looked at included vitamins A, B, C, and E.

On the other hand, most of the multivitamin research comes from the time before antiretroviral therapy (ART). ART is now the standard drug treatment for HIV. And newer research has shown that, while safe, multivitamins don’t have the same benefits among people taking ART or other similar drugs.

Vitamin D

Some people call vitamin D “the sunshine vitamin.” That’s because your body can make it using sunlight absorbed into your skin.

Some foods naturally contain vitamin D. Those include fatty fish like salmon as well as eggs and some dairy products. Some foods also include added vitamin D. Examples are milk, alternative milks, orange juice, and breakfast cereals.

If you eat a lot of these foods, or if you spend time outdoors in the sun, you may get all the vitamin D your body needs.

But many people with HIV have low vitamin D levels. There’s also some evidence that ART therapy may lower vitamin D levels. This is a problem because vitamin D is important for bone health, and it also supports the immune system.

Some research has found that adults and kids who take vitamin D supplements improve their body’s levels of the vitamin. But whether this provides health benefits for people with HIV is not clear.

Vitamin D supplements may turn out to be helpful for people with HIV. But right now, everything is still up in the air.


DHEA helps support healthy hormone levels in the body. There’s some evidence it can boost mood, energy levels, and quality of life among people with HIV.

But some research shows there’s no reason for people with HIV to take it. And taking too much DHEA may also raise hormones to unhealthy levels.

Other Supplements That May Help

Other vitamins and nutrients also play a role in immune health. Some also help repair damaged cells. Supplements that contain these nutrients may be helpful for those who have HIV.

These include:

But again, the benefits are uncertain. It’s also not clear how much someone with HIV needs to take in order to see these benefits. In some cases, these vitamins or supplements may interfere with medications for HIV.

Be sure you talk to your doctor before you start on any supplement.

Supplements to Avoid

Certain supplements may be risky for people with HIV. Some of these supplements can interfere with HIV medications. Research has linked others to risks that have nothing to do with HIV.

Be sure to talk with your doctor before taking a supplement that contains vitamin A or iron. Vitamin A can be toxic in high doses. Iron may increase the activity of certain types of bacteria in your body. Both can be problematic for people with HIV.

There are also countless supplement products that claim to strengthen or boost the immune system. Many contain complex combinations of ingredients that could be risky.

While it’s possible that some of these could help people with HIV, the evidence is shaky even when it comes to very well-researched and common vitamins.

Try to Get Your Nutrients From a Healthy Diet

Some vitamin or nutrient supplements may be helpful. But medical professionals usually recommend people try to get all the vitamins and nutrients they need from food.

Try to eat a range of foods, especially a variety of colored vegetables. If you decide to also take a supplement, be sure to discuss it with your doctor first.
