Dehydroepiandrosterone (DHEA) is a steroid hormone produced primarily by the adrenal glands, which are located on top of your kidneys. It’s also produced in small amounts by the testes in men and the ovaries in women. DHEA serves as a precursor to male and female sex hormones, including testosterone and estrogen.
Key Points about DHEA:
- Hormone Precursor: DHEA is often referred to as a prohormone because it is a precursor to other important hormones. This means that the body converts DHEA into hormones like testosterone and estrogen, which play vital roles in many bodily functions.
- Production and Levels: DHEA production peaks in early adulthood and then gradually declines with age. By the time individuals reach their 70s or 80s, DHEA levels are typically only about 10-20% of their peak levels.
- Functions in the Body:
- Hormonal Balance: As a precursor to sex hormones, DHEA helps maintain hormonal balance, which is crucial for reproductive health and overall well-being.
- Immune System: DHEA has been shown to have a role in modulating the immune system, potentially enhancing immune response.
- Bone Density: It helps maintain bone density, which is important for preventing conditions like osteoporosis.
- Muscle Mass and Strength: DHEA is involved in maintaining muscle mass and strength, especially as people age.
- Cognitive Function and Mood: Research indicates that DHEA may have positive effects on mood and cognitive function, potentially reducing symptoms of depression and improving memory.
- Supplementation: Due to its decline with age, DHEA is often taken as a supplement, especially by older adults seeking to restore their hormone levels. It is available over-the-counter in many countries, but its use should be guided by a healthcare provider due to potential side effects and interactions with other medications.
- Research and Benefits:
- Hormonal Replacement: Some studies suggest that DHEA supplementation can help improve hormonal balance, muscle strength, immune function, bone density, libido, and mood (Nair et al., 2006).
- Safety: While generally considered safe, the long-term effects of DHEA supplementation are still under investigation, and it can have side effects, particularly if used improperly.
DHEA is a crucial hormone with various functions in the body, particularly as a precursor to sex hormones. It plays a role in maintaining several aspects of health, especially as we age, and is available as a supplement for those seeking to mitigate the effects of its natural decline. However, its use should always be discussed with a healthcare professional to ensure safety and effectiveness.
