Do "testosterone boosters" really increase serum total testosterone? A systematic review
Morgado A, Tsampoukas G, Sokolakis I, Schoentgen N, Urkmez A
Published in International Journal of Impotence Research
Methodology
Systematic review of 52 studies covering 27 marketed testosterone boosters, including D-aspartic acid, assessing total testosterone versus placebo across athletes, hypogonadal, infertile and healthy men
Key Findings
Most marketed testosterone boosters, including D-aspartic acid, lacked convincing evidence of raising total testosterone versus placebo.
Conclusions
Claims made for D-aspartic acid as a testosterone booster are not supported by the pooled published evidence.
Limitations
Narrative synthesis across heterogeneous products; only two D-aspartic acid studies included.
Supplements Studied
Our primary objective was to systematically review all data published in the last two decades on testosterone boosters and determine their efficacy.
