How to Take DHEA & 5-HTP

Updated April 07, 2017

DHEA (dehydroepiandrosterone) is an adrenal hormone that can be converted in the human body into both testosterone and oestrogen. 5-HTP (5-Hydroxytryptophan) is a metabolite of an amino acid (a kind of protein) called tryptophan. DHEA deficiency has been associated with some late-life conditions and diseases, including loss of lean muscle mass and diminished libido. 5-HTP is associated with the production of a neurotransmitter called serotonin. Neither DHEA nor 5-HTP is regulated. DHEA, which is banned as a performance-enhancing drug by the World Anti-Doping Agency, may encourage muscle development. 5-HTP may be useful in treating depression, insomnia and Parkinson's disease.

Buy both DHEA and 5-HTP in capsule form made by manufacturers you trust.

Buy 25-mg capsules of DHEA and 50-mg capsules of 5-HTP. Store both substances in a cool, dry place.

Take 25 mg of DHEA two to four times a day with food and water as a food supplement. Stop taking DHEA if you experience heart palpitations.

Take 50 mg of 5-HTP twice a day with food and water as a food supplement. 5-HTP is often recommended as an untested alternative to serotonin reuptake inhibitors like Prozac. Stop taking 5-HTP if you begin to experience unexplained muscle soreness.


An apparent contaminant in some batches of 5-HTP has been associated with a rare muscle disease called eosinophilia-myalgia syndrome. Some sources classify DHEA as an anabolic steroid that may contribute to prostrate enlargement, gynaecomastia, hair loss and may exacerbate certain cancers such as prostrate cancer.
