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.
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.
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.
EvidenceSupported by controlled trialsTime to resultsTypically 8–12 weeks (trials ran about 3 months)
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.
Dietary antioxidant with meta-analysis support for sperm count
Why it may be relevant
If you want to guard sperm quality, lycopene is the red carotenoid antioxidant found in tomatoes, studied for reducing the oxidative stress that can affect sperm.
A meta-analysis of clinical trials found lycopene modestly improved sperm concentration in men; the benefit is real but limited to certain parameters, so treat it as a supportive option.
Dose or use Follow product labeling; consult a healthcare practitioner.
Key study Systematic review and meta-analysis (2025, PMID 40806357): Association of Lycopene and Male Reproductive Health. Pooling four clinical studies (151 men), lycopene supplementation significantly improved sperm concentration and non-progressive motility versus control, with no clear effect on other parameters.
EvidenceSupported by controlled trialsTime to resultsTypically 8-12 weeks
Caution: Generally well tolerated at dietary supplement doses; if you take blood-pressure or blood-thinning medication, check with your doctor first.

Deficiency may impact sperm health — worth checking
Why it may be relevant
If you suspect nutritional gaps are involved, vitamin D deficiency is common and correcting it may support male reproductive health.
If your vitamin D is low, correcting it may modestly support sperm concentration, motility, and testosterone. Pooled trials show small but real improvements, strongest in men who start out deficient — so it's worth testing your level first.
Dose or use 1,000–2,000 IU daily is commonly used; get your levels tested and follow your practitioner's guidance.
Key study Systematic review and meta-analysis (2026, PMID 42004696): across eight RCTs and three observational studies (1,168 infertile men), vitamin D supplementation was associated with small but statistically significant improvements in semen volume, sperm concentration, progressive motility, and testosterone, with the clearest signal in men who were deficient.
