The Impact of Dehydroepiandrosterone on Athletic Performance
Dehydroepiandrosterone (DHEA) is a naturally occurring hormone in the body that has been the subject of numerous scientific studies in recent years. While it has been primarily studied for its potential anti-aging effects, there is also growing interest in its impact on athletic performance. In this article, we will explore the current research on DHEA and its potential benefits for athletes.
What is DHEA?
DHEA is a steroid hormone produced by the adrenal glands, gonads, and brain. It is a precursor to other hormones, including testosterone and estrogen, and plays a role in various bodily functions such as metabolism, immune response, and brain function.
As we age, our DHEA levels naturally decline, leading to potential health issues. This has led to the use of DHEA supplements as a potential anti-aging therapy. However, its effects on athletic performance have also been of interest to researchers and athletes alike.
Effects on Athletic Performance
Several studies have investigated the potential impact of DHEA on athletic performance, with mixed results. One study found that DHEA supplementation in older men increased muscle strength and lean body mass, while another study in young men showed no significant changes in muscle strength or body composition.
However, a more recent study published in the Journal of the American Medical Association (JAMA) found that DHEA supplementation in older men and women did not improve muscle strength or physical performance. This study also noted potential adverse effects, such as an increase in LDL cholesterol levels.
On the other hand, a study published in the Journal of Applied Physiology found that DHEA supplementation in young men and women improved muscle strength and power, as well as aerobic capacity. These findings suggest that DHEA may have a more significant impact on athletic performance in younger individuals.
Pharmacokinetics and Pharmacodynamics
The pharmacokinetics of DHEA have been well-studied, with a half-life of approximately 15-30 minutes. This means that it is quickly metabolized and excreted from the body. As a result, DHEA supplements need to be taken multiple times throughout the day to maintain consistent levels in the body.
The pharmacodynamics of DHEA are not as well understood, but it is believed to exert its effects through conversion to other hormones, such as testosterone and estrogen. This conversion is dependent on various factors, including age, gender, and overall health.
Real-World Examples
While the research on DHEA and athletic performance is still ongoing, there are some real-world examples of its use in the sports world. In 2018, the World Anti-Doping Agency (WADA) removed DHEA from its list of prohibited substances, citing insufficient evidence of its performance-enhancing effects.
However, some athletes have reported using DHEA as part of their supplement regimen, claiming it helps with muscle recovery and overall performance. One example is former NFL player and current MMA fighter, Herschel Walker, who has openly discussed his use of DHEA and its benefits for his athletic career.
Expert Opinion
While the current research on DHEA and athletic performance is still inconclusive, there is growing interest in its potential benefits. Some experts believe that DHEA may have a more significant impact on younger individuals, as seen in the study published in the Journal of Applied Physiology.
However, it is essential to note that DHEA supplementation is not without potential risks and side effects. As with any supplement, it is crucial to consult with a healthcare professional before use, especially for athletes subject to drug testing.

Overall, while the current research on DHEA and its impact on athletic performance is still inconclusive, there is growing interest in its potential benefits. As with any supplement, it is essential to consult with a healthcare professional before use and be aware of potential risks and side effects. As the research continues, we may gain a better understanding of DHEA’s role in athletic performance and its potential benefits for athletes.
