DHEA has long been purported to increase testosterone and muscle mass in bodybuilders but studies show that’s not the case. DHEA doesn’t have any effect on testosterone and will not increase gains from a resistance training program. A few studies do show mild cognitive benefits in older individuals while many other studies show no benefit, so the evidence for older adults is inconclusive.
The Study: Brown, G. A., Vukovich, M. D., Sharp, R. L., Reifenrath, T. A., Parsons, K. A., & King, D. S. (1999). Effect of oral DHEA on serum testosterone and adaptations to resistance training in young men. Journal of Applied Physiology, 87(6), 2274-2283.
