Dual-soluble antioxidant with RCT support for sperm motility

Why it may be relevant

If you want antioxidant protection for sperm, ALA is both water- and fat-soluble, so it works throughout the cell — including the mitochondria that power sperm movement.

Why try it

Alpha-lipoic acid neutralizes free radicals and helps regenerate other antioxidants like vitamins C and E. Pooled randomized trials in infertile men link it to better sperm motility and fewer abnormally shaped sperm.

Dose or use

600 mg daily is a commonly studied range; follow product labeling and consult a practitioner.

Time to results

Typically 8–12 weeks (trials ran about 3 months)

Key study

Systematic review and meta-analysis (2025, PMID 40327515): across five randomized trials (250 infertile men), alpha-lipoic acid improved total and progressive sperm motility and reduced abnormal sperm morphology versus placebo.

Caution

Generally well tolerated; alpha-lipoic acid may lower blood sugar, so use caution if you have diabetes or take glucose-lowering medication, and check with your doctor first.
