Forms Comparison

FormBioavailabilityBest For
Micronized DHEAHighStandard oral supplementation — micronization improves absorption and provides more consistent blood levels
7-Keto DHEAModerateNon-hormonal metabolite — does not convert to testosterone or estrogen; primarily studied for metabolic rate and body composition
DHEA Cream (transdermal)Moderate-HighTopical application — avoids first-pass liver metabolism; may provide more favorable DHEA-to-androgen conversion ratios

Micronized DHEA

Bioavailability: High. Best for: Standard oral supplementation — micronization improves absorption and provides more consistent blood levels.

7-Keto DHEA

Bioavailability: Moderate. Best for: Non-hormonal metabolite — does not convert to testosterone or estrogen; primarily studied for metabolic rate and body composition.

DHEA Cream (transdermal)

Bioavailability: Moderate-High. Best for: Topical application — avoids first-pass liver metabolism; may provide more favorable DHEA-to-androgen conversion ratios.
