Introduction

The 2023 CRN Consumer Survey on Dietary Supplements shows that supplements have become a mainstream part of Americans’ lives, with 74 percent of U.S. adults using dietary supplements and 55 percent identified as “regular users.”
Further analysis highlights that people use supplements not just to address nutritional gaps—such as not consistently eating enough fruits and vegetables—but also to support active, healthier lifestyles and to achieve overall wellness. Although immunity remains a leading reason for supplement use, it has slightly decreased compared to previous years.
Interestingly, 92 percent of supplement users agree that dietary supplements are important for maintaining their health, according to a new question added to this year’s survey.
For men looking to boost fertility, the following five vitamins and minerals are considered most beneficial.

The Best Vitamins for Male Fertility

Below are the 5 best vitamins or minerals that can help improve male fertility.

1. Zinc
Zinc is a crucial nutrient for both male and female fertility. It supports the proper function of reproductive organs and is a vital part of genetic material like DNA and chromosomes. A deficiency in zinc, whether in the male or female partner, may cause chromosomal changes in egg or sperm cells, potentially leading to fertility issues or miscarriage. In men, zinc is essential for sperm production, forming both the outer layer and the tail of sperm. Studies from University Hospital Nijmegen in The Netherlands, including one published in Fertility and Sterility in 2000, found that low zinc intake is associated with reduced testosterone and sperm counts. Daily supplementation with 30 to 60 mg of zinc may help raise sperm counts.

2. CoEnzyme Q10 – CoQ10
CoQ10 is a generally safe dietary supplement that requires a practical and low dose for preserving male fertility. Also known as "ubiquinone," CoQ10 supplements show a strong safety record and some evidence that they may lower blood pressure in people with hypertension, as well as reduce statin-related muscle pain. Seminal fluid naturally contains CoQ10, and levels appear to correlate with sperm count and motility. Men with idiopathic asthenozoospermia may see improved sperm motility by taking 200 mg daily for six months. Another study involving 212 infertile men taking 300 mg for 26 weeks showed notable improvements in sperm density, motility, and acrosome reaction.

3. L-Carnitine
L-carnitine, an amino acid, is vital for the normal function of sperm cells. According to the National Institutes of Health’s Office of Dietary Supplements, higher levels of L-carnitine in sperm cells are linked to better sperm count and quality. L-carnitine is naturally most abundant in red meat and dairy products, meaning vegetarians aiming to maintain fertility might particularly benefit from supplementation.

4. Vitamin C
Vitamin C has enough indirect data and long-term safety evidence to suggest a possible small role in improving male subfertility. Some preliminary findings indicate that men taking between 200 to 1,000 mg of vitamin C daily, often along with other antioxidants, may see fertility benefits. Supplementation can increase vitamin C levels in seminal plasma for both smokers and non-smokers, which may be associated with improved sperm morphology. Notably, seminal plasma holds vitamin C concentrations much higher than those found in the bloodstream.

5. Selenium
Selenium plays a critical role in fertility for both men and women. Acting as an antioxidant, selenium helps prevent chromosome breakage—a factor associated with birth defects and miscarriages. In men, maintaining adequate selenium levels is important for maximizing sperm production. Low sperm counts are often found in men who also show lower selenium levels in their blood.

Conclusion

When it comes to boosting reproductive health, making the right choices with supplementation can make a real difference. As highlighted, nutrients like zinc, CoQ10, L-carnitine, vitamin C, and selenium play important roles in supporting sperm quality, motility, and overall fertility potential. Whether you are looking to correct nutritional gaps or simply optimize your health for conception, incorporating these key vitamins and minerals into your daily routine can be a powerful step forward.
Remember, while supplements can offer great support, they work best alongside a healthy diet and lifestyle. Before starting any new supplement regimen, it’s always wise to consult with a healthcare provider, especially when fertility is the focus.
