Sperm health and male fertility and Natural Supplements: What the Latest Research Says About Nanocurcumin and Alpha Lipoic Acid
I, Dr. Conor Kerley, am a fertility nutrition expert. I am a member of the European Fertility Society (EFS) and have written expert articles about nutrition Sperm health and male fertility for EFS.
So I keep up with the research around which ALL aspects of lifestyle, especially nutrition and nutrients which have benefits or harms for sperm health and male fertility.
Recent clinical research in men with sperm issues suggests that two supplements 1) Nanocurcumin + 2) Alpha lipoic acid
- Increased total sperm count
- Increased sperm concentration
- Increased sperm motility
- Increased antioxidant capacity
- Decreased oxidative stress
- Decreased inflammation
in men with sperm issues
At Phytaphix, we know the science!
That’s why we’ve built the 90 day Sperm health bundle
3 month supply of both nanocurcumin as gold standard curcumin and R Alpha lipoic Acid as Lipoic Acid Phix with ginger extract and 13 essential micronutrients, including methylfolate, vitamins B12, D3 as well as selenium & zinc
While they are not a cure and should not replace medical treatment, human studies in men with sperm issues have shown encouraging benefits and safety, particularly when highly bioavailable forms are used.
Why Are Scientists Interested in Nutrition and specific nutrients for sperm issues?
Issues with sperm health are associated with:
- oxidative stress
- inflammation
- immune dysfunction
Certain nutritional strategies, including food supplements can target and improve all 3 of these areas and hence may provide significant benefit to men with sperm issues.

alpha lipoic acid reduce sperm DNA damage and lipid damage while enhancing sperm total
motility and genetic quality in the male partner of couples with recurrent Pregnancy Loss
Lipoic Acid study 4 conclusions
alpha lipoic acid leads to improvements in reproductive hormones (including testosterone) in blood, and significantly reduces the generation of oxidative stress increases the gene expression and activity of antioxidants in seminal fluid.

Lipoic Acid study 6 conclusions
alpha lipoic acid supplementation in patients with asthenozoospermic
enhanced sperm quality and viability

Curcumin and sperm health and male fertility
Laboratory and animal studies have consistently shown that curcumin influences many of the biological processes involved in sperm health and male fertility
Research suggests curcumin may help:
- Increase sperm count
- Increase sperm motility
- Increase sperm morphology
- Increase sperm viability
- Reduce inflammation
- Reduce oxidative damage
These findings are encouraging because sperm health is influenced by altered immune function, chronic inflammation and oxidative stress.
However, laboratory research alone does not prove that a supplement will work in people. So what does the human research show?
Curcumin supplementation in men with sperm issues
As of writing, there are NO studies examining turmeric or curcumin supplementation in men with sperm issues. So taking turmeric or even curcumin supplements is unlikely to help improve sperm quality.
Nanocurcumin: A Better Form of Curcumin
Nanocurcumin is designed to overcome one of the biggest limitations of conventional curcumin by dramatically improving its absorption, by up to 285%!
Because the curcumin particles are much smaller, more of the active compound can reach the bloodstream and the tissues where it is needed and can have benefit.
This improved bioavailability has led researchers to investigate whether nanocurcumin may produce better clinical outcomes than standard curcumin.
Nanocurcumin and Female Fertility Health
Nanocurcumin and endometriosis
Nanocurcumin and PCOS
But what about nanocurcumin regarding sperm health and male fertility?
Clinical Research on Nanocurcumin and sperm health and male fertility
Study Snapshot

Best Vitamins and Supplements for Sperm Health and Male Fertility: Alpha Lipoic Acid
Laboratory and animal studies have consistently shown that alpha lipoic acid influences many of the biological processes involved in sperm health and male fertility:
Research suggests alpha lipoic acid:
- Increased total sperm count,
- Increased sperm concentration
- Increased sperm motility
- Increased antioxidant levels
- Decreased inflammation
- Decreased oxidative stress
- Decreased total oxidative stress

The Problem with Standard Alpha Lipoic Acid
Most food supplements use artificially produced lipoic acid as it’s easier to manufacture with but standard alpha lipoic acid
- Artificially manufactured
- Not naturally occurring
- Suboptimal absorption and biological activity
- Can cause heart burn and stomach issues
R-alpha Lipoic Acid: A Better Form of Lipoic Acid
The R form of Alpha Lipoic Acid has multiple benefits:
- The naturally occurring form
- Better absorption
- More biologically active
- Better health effects
- Better tolerance i.e. less side effects
Lipoic Acid and female fertility

- Alpha lipoic acid and Female fertility
But what about alpha lipoic acid and sperm health and male fertility?
Clinical Research on Alpha Lipoic Acid supplementation on sperm health and male fertility
There are 7 human studies regarding Alpha Lipoic Acid supplementation in men with sperm issues. Across these seven published human studies to date, alpha lipoic acid supplementation has consistently been associated with improvements in sperm quality!
The earliest study of lipoic acid in men comes from 2015 and reported increased sperm count, increased sperm concentration, increased sperm motility, increased levels of antioxidants in the semen and decreased levels of harmful oxidative stress.
The next study came in 2020 and examined the effect of lipoic acid in men with varicocele who had surgery (varicocelectomy). Lipoic acid supplementation increased sperm motility and decreased sperm DNA damage and oxidative damage.
A 2021 study reported improvements in reproductive hormones like testosterone and decreases in oxidative stress as well as increased antioxidant in semen.
A 2022 study reported improvements in reproductive hormones like testosterone and decreases in sperm DNA fragmentation and oxidative stress as well as increased antioxidant in semen. Remarkably, this study reported increased pregnancy rates in the partner even though lipoic acid was only taken by the male.
A 2023 study examined the effect of lipoic acid supplement in men who were in a couple that had experienced multiple pregnancy losses (RPL) or miscarriages. Alpha lipoic acid supplementation led to decreased sperm DNA damage and oxidative stress while increasing both sperm movement (motility) as well as pregnancy rate! A 2023 study reported that lipoic acid supplementation increased sperm volume, sperm concentration, sperm motility and sperm viability.
The most recent study of alpha lipoic and sperm health comes from this year, 2026. This study examined the effect of lipoic acid in men who were in a couple that had experienced multiple pregnancy losses (RPL) or miscarriages and reported that lipoic acid improved sperm concentration, motility and morphology while decreasing sperm DNA fragmentation.
In addition to direct studies assessing the direct effect of lipoic acid supplementation of sperm health, there is an expert review from World Journal of Men’s Health in 2025 titled: ‘Role of Lipoic Acid in Testosterone Production in Males which concluded: ‘lipoic acid consistently restores testosterone levels, offering promise as an intervention in testicular health, especially in cases of testicular toxicity caused by various harmful agents’
As you can see, alpha lipoic acid is backed by research and worth considering for all men with sperm issues and all men a couple that had experienced multiple pregnancy losses (RPL) or miscarriages.
What Does the Current Evidence Tell Us?
Human studies in men with sperm issues have shown encouraging improvements in multiple aspects of sperm health as well as even increasing pregnancy rates!
Why Choose Lipoic Acid Phix?
✓2 capsules daily
✓Superior form of alpha lipoic acid (R Alpha Lipoic Acid)
✓Research based dose
✓ Formulated by fertility nutrition expert, Dr. Conor Kerley
✓ Enriched with ginger extract

Current evidence suggests that nanocurcumin and alpha lipoic acid are both safe AND beneficial in men with sperm issues. However, supplements should complement, not replace, the treatment plan recommended by your healthcare professional.
