What DHEA is and why it is different
DHEA is a hormone your adrenal glands make, and supplements raise hormone levels rather than fill a nutrient gap. That is why it is prescription-only in several countries and why a clinician should be involved.
What the evidence supports
The strongest findings are in specific clinical situations such as adrenal insufficiency. Evidence for general anti-ageing, energy or body composition claims in healthy adults is weak and inconsistent.
Questions to raise with a clinician
Your current hormone levels, anything you already take, and any hormone-sensitive condition in your history. These are the questions that decide whether DHEA is appropriate at all.
Questions people ask about DHEA
- What does DHEA do?
- It is a precursor your body converts into other hormones including testosterone and oestrogen. Supplementing raises those downstream levels, which is the reason for the caution.
- Is DHEA available over the counter?
- It is sold as a supplement in the United States, and it is prescription-only or restricted in the UK, Canada, Australia and much of Europe.
- What dose of DHEA is typical?
- Retail products commonly range from 25 to 100 milligrams. Dose is a clinical decision rather than a shelf one, particularly given the hormonal effect.
- Who should not take DHEA?
- Anyone with a hormone-sensitive condition, anyone pregnant or breastfeeding, and anyone on hormone therapy, without a clinician saying otherwise.
- Does DHEA show up on a drug test?
- It is banned by WADA and prohibited in most tested sport. If you compete under anti-doping rules, treat it as prohibited.
This is a hormone, not a vitamin
