Which of the following is an effect of DHEA?

Dehydroepiandrosterone (DHEA) is a hormone produced by the adrenal glands and is often supplemented for its potential benefits. One recognized effect of DHEA supplementation is its influence on immune function. Studies have suggested that DHEA can enhance immune response, particularly in older adults, by potentially increasing the number and activity of immune cells, such as T cells and natural killer cells. This can lead to improved immune surveillance and a better capacity to fight off infections.

The other options reflect misconceptions or unsubstantiated claims regarding DHEA’s effects. While some may discuss the potential for DHEA to influence body fat or recovery time, evidence supporting these claims isn't robust. Additionally, concerns about serious cardiovascular damage are contrary to many studies, which typically note that DHEA is safely used when monitored and for appropriate individuals, particularly in specific therapeutic contexts. Hence, the assertion regarding increased immune function aligns well with existing research on DHEA’s role in enhancing the immune response.
