I’VE HEARD THAT TAKING THE AMINO ACID glutamine with creatine can have positive effects in people who are HIV-positive. But there doesn’t seem to be much information about these sports supplements and any potential interactions with HAART therapy. Can you shed some light on this? —John, West Hollywood

You’re right. Studies on the role of micronutrient supplementation in people with HIV are ripe for further research, according to Dr. Alice Tang, associate professor at Tufts University School of Medicine, and an expert in the area of supplementation and HIV. A few of these studies have examined glutamine, primarily for its muscle-building effects. To my knowledge, there are no published studies on creatine in people with HIV.
