Insufficient

evidence for d-aspartic acid

Our honest take

D-aspartic acid in capsules, sold as a testosterone booster for men. It became popular after one small study, but later trials in men who train found no meaningful rise in testosterone or strength, and one found a fall at 6 g a day; there are no authorised claims. It is very cheap, but cheap does not make it worthwhile; sleep, training and diet matter far more, and your GP can check your testosterone if you are concerned.

You are an adult man who wants to try DAA despite the weak evidence, at minimal cost
You want a single-ingredient product rather than a blend of herbs and stimulants
You are under 18, a woman who is pregnant or breastfeeding, or have a hormone-related condition
You take regular medication and have not checked with your pharmacist
You are worried about low testosterone: ask your GP for a blood test instead

The science

D-aspartic acid· evidence: Insufficient

D-aspartic acid (DAA) is an amino acid involved in hormone signalling. It became popular as a testosterone booster after one small study, but later trials in men who train found no meaningful rise in testosterone or gains in strength, and one found a drop at 6 g a day.

There are no authorised health claims for D-aspartic acid, so we make no claims about what it does. If you are worried about low testosterone, a simple blood test through your GP is the way to find out.

Typical dose: Products typically give 2 to 3 g a day.

Safety: Not for under-18s, or in pregnancy or breastfeeding. Long-term safety data are limited. Speak to your GP first if you take regular medication or have a hormone-related condition.
