Although a standard dosage for DHEA has not been established yet, general dosing recommendations are available based on clinical studies. Various studies have used doses ranging from 25 mg to 2.5 grams. However, these doses are probably much too high for use without your healthcare provider's supervision. It is reasonable to follow the directions on the label of your particular DHEA product.
The best dose for DHEA (dehydroepiandrosterone) for any use has not yet been determined. Because DHEA is a dietary supplement (not a drug) there is little information available to provide guidance about safe and effective DHEA dosages.
Studies have used a wide range of DHEA dosages, ranging from 25 mg up to 2.5 grams (2500 mg) daily. Keep in mind that these dosages were used in a controlled, clinical environment with close supervision and careful selection of the individuals in the studies. These dosages (even 25 mg a day) are probably much too high for use without your healthcare provider's supervision. After all, DHEA is a hormone and could potentially severely disrupt the delicate balances of your hormones. In fact, it is advisable that you use DHEA only with your healthcare provider's approval and supervision, no matter what dosage.
The best DHEA dosage has not been clearly established for any use. It is reasonable to follow the directions on the label of your particular DHEA product. Do not exceed these recommendations unless your healthcare provider specifically instructs you to do so.
Lastly, it should be noted that there is some concern that high DHEA dosages, especially when used long-term, may be quite dangerous and might increase the risk of various cancers.
