DHEA hormone levels usually go down with age. Advocates believe that bringing the levels back to youthful proportions can have dramatic beneficial effects on the mind and body. The notion of restoring DHEA to a youthful level is like a "tonic" to prevent the ravages of aging. DHEA enhances brain function and memory, improves sexual performance, soothes stress and promotes real being, assists in weight loss, provides energy, and promotes youthful appearance and prolong life expectancy.
