Studies have also shown DHEA’s effect on reducing cortisol levels – a stress hormone that may have negative effects on strength – and preserving muscle mass (reducing muscle damage) during high intensity endurance, strength, and HIIT training (high intensity interval training). One study even found that the muscle preserving effects of DHEA supplementation during intense exercise resulted in 300% less creatine kinase (muscle damage). Without this additional damage, recover and growth are thought to happen at a much faster rate.*
Along with reduced cortisol levels, DHEA also promotes the production of beta-endorphin, one of the brain’s natural feel-good substances that can result in greater happiness and a more positive attitude. Studies also support DHEA’s ability to lessen the buildup of the beta-amyloid (a protein) in the brain, which may reduce cognition loss that comes from aging and a major contributor to Alzheimer’s disease.*
Finally, DHEA acts as an antioxidant – especially in the hippocampus area of the brain – which may also contribute to memory and learning ability.
