DHEA production peaks in your mid-20s and then declines approximately 2-3% per year. By age 70, most people have only 10-20% of the DHEA they had at their peak. This progressive decline parallels many of the changes we associate with aging: loss of muscle mass, decreased bone density, reduced energy, lower libido, and mood changes.
As a precursor hormone, DHEA sits at the top of the hormonal cascade that produces testosterone, estrogen, and other sex hormones. Supplementation may support the body's ability to maintain healthy levels of these downstream hormones as it ages. Clinical studies have shown benefits for bone density, body composition, skin health, and reported wellbeing in older adults.
DHEA also supports adrenal function. It's produced primarily by the adrenal glands, and chronically elevated cortisol (from prolonged stress) can suppress DHEA production, creating an unfavorable cortisol-to-DHEA ratio. Supplementation may help restore this balance, particularly for those dealing with chronic stress or adrenal fatigue.
