Does D-Aspartic Acid Help With In a small RCT of infertile males, D-aspartic acid combin...?

Evidence Summary

In a small RCT of infertile males, D-aspartic acid combined with ubiquinol and zinc (2660 mg/day for 3 months) significantly improved progressive sperm motility and increased total testosterone levels (PMID: 40248985). Animal and metabolic research suggests D-aspartic acid accumulates in tissues in a dose-dependent manner and may influence lipid metabolism and neurotransmission pathways (PMID: 41086472). However, short-term supplementation at 3 g/day for 2 weeks in trained male climbers showed no significant effect on testosterone, free testosterone, or luteinizing hormone (PMID: 29893592).
