Hormones
The adrenal hormone that declines sharply with age
Dehydroepiandrosterone (DHEA) is a steroid hormone produced by the adrenal cortex, gonads, and brain. It is the most abundant circulating steroid hormone in the body and a precursor to both testosterone and oestrogen. DHEA levels peak at age 25 and decline 80–90% by age 70. Interest centres on replacing this decline to support energy, libido, cognitive function, and body composition. Evidence is mixed — most benefits seen in people with low DHEA-S levels.
Micronised DHEA (better absorption); 7-keto DHEA (non-androgenic; does not convert to sex hormones)
25–50 mg/day (always under medical guidance)
Do NOT take without a DHEA-S blood test and medical supervision. DHEA is a hormone and can cause androgenic side effects (acne, facial hair in women, hair loss) and may worsen hormone-sensitive cancers. Not appropriate for anyone under 40.
