Written by Andrew Le, MD

UpdatedFebruary 22, 2024

As men age, it’s common for them to experience a decline in sexual vigor, which can manifest as a lower libido, reduced erectile strength, or diminished semen volume and orgasm activity. However, there's no shame in experiencing these symptoms, as they are more common than you might think. Some nutritional supplements claim to remedy the situation, including Semenax, a branded combination of botanicals, vitamins, minerals, and amino acids sold by Leading Edge Health.

In this article, we'll take a close look at Semenax's ingredients and customer experience to help you understand its potential value. We'll provide a neutral and knowledgeable assessment of the product, so you can make an informed decision about whether Semenax is right for you.

What is Semenax?

Semenax is a male enhancement pill produced by Leading Edge Health. Its primary goal is to increase semen volume, with improvements in erectile performance and orgasm intensity as secondary goals. Semenax belongs to a subcategory of male enhancement products known as volume pills.

The idea behind Semenax is that men might experience a decrease in semen volume due to nutritional deficiencies. Semenax aims to close the gap in some deficiencies, specifically zinc deficiency, which is prevalent globally. However, men who eat healthily, exercise regularly, and have no underlying conditions might not see much change in their sex lives with Semenax.

Compared to prescription PDE-5 inhibitors like Viagra or Cialis, Semenax is not as effective in improving erectile performance. However, the company's small-scale clinical study showed that Semenax significantly improved ejaculate volume, which is its primary goal.

Semenax has a lengthy ingredient list and dedicated research, which sets it apart from other volume pills. However, the doses of those ingredients are not particularly high, and the length of the list is not enough for it to rise far above its competition.

Other ingredients include cellulose, gelatin, vegetable stearate, and silicon dioxide. It's worth noting that the presence of gelatin makes Semenax unsuitable for vegans and vegetarians.

Who Should Take Semenax?

Semenax is a supplement designed for men who produce less than 3ml of semen, have low libido, are unable to achieve a firm erection, or are suffering from low testosterone. However, it is important to note that there are many potential causes for these issues, and taking a supplement alone may not be sufficient. We recommend consulting with a doctor, undergoing a testosterone test, and developing a plan to address your specific needs. This plan may include Semenax as a supplement, but it should be part of a comprehensive approach to improving your sexual health.

Does Semenax work?

When it comes to Semenax, there is no real evidence that it will work for most men. However, based on the ingredients it contains, it may help men with low testosterone levels work toward normalcy, and men with sexual performance issues related to blood flow issues or a vitamin E deficiency might see a small difference. But without credible research looking at how these ingredients might work together, we can’t guarantee the effectiveness of Semenax.

Semenax sponsored a randomized, double-blind, and placebo-controlled clinical study to investigate its effectiveness. The results showed that a double dose of Semenax significantly boosted semen volume by just under 20%. Other results were mixed.

Is Semenax legitimate?

Semenax is a legitimate company. Its parent company, Leading Edge Health, provides good customer support, making it easy to reach someone if you have a question, need to return the product, or have an issue with your order. The 67-day money-back guarantee offered by Semenax provides decent protection in the event that you experience no positive results.

In conclusion, while Semenax may work better than some of its competitors for specific subsets of men, there is no guarantee that it will work for most. The results of Semenax's clinical trials are mixed, and without credible research looking at how the ingredients might work together, we cannot confidently recommend Semenax as an effective solution.

Is Semenax Safe?

Semenax is generally safe and well-tolerated by most men when used as directed. However, individuals with pre-existing medical conditions such as blood pressure issues, heart problems, or diabetes should consult their doctors before using Semenax. This is to ensure that the supplement does not interfere with any medications or exacerbate any existing health conditions.

One of the ingredients in Semenax, horny goat weed, may cause breathing difficulties in some individuals. Additionally, it may increase the risk of bruising and bleeding in people who are taking blood thinners.

To ensure your safety, we recommend that you always share your plans to use Semenax with your doctor. It's always a good idea to communicate any new supplement you're adding to your routine with your healthcare provider.

How Does Semenax Work?

Semenax is a supplement that claims to improve ejaculate volume, orgasm intensity, fertility, and erectile performance. It does this by employing a formula containing botanical ingredients, zinc, and vitamin E. Each ingredient in Semenax is intended to work together to achieve these goals.

Vitamin E

Vitamin E is an ingredient in Semenax that has shown promise in studies looking at semen parameters in geese. However, a study in humans showed no meaningful difference in IVF outcomes among patients taking a vitamin E supplement over twice the size of the serving in Semenax compared to those not taking it.

Zinc Aspartate

Zinc aspartate is an ingredient in Semenax that has the most potential. A link between zinc and testosterone levels has been well established, and healthy testosterone levels lead to healthy sperm. In and of itself, zinc has an important role to play in fertility. However, if you already have healthy testosterone levels or take a multivitamin with a good dose of zinc in it, Semenax might not make a difference.


L-carnitine is an ingredient in Semenax that has been shown to improve motility in mice semen. However, studies into the potential for carnitine supplementation to improve semen parameters are lacking.

Maca Root

Maca root is an ingredient in Semenax that has been found to improve men’s sexual health in studies. However, the studies included typically used maca doses ranging from 1,200mg-3,500mg per day, which is far more than the 400mg used in Semenax.

Pine Bark Extract and L-arginine HCl

Pine bark extract and L-arginine HCl are ingredients in Semenax that have been shown to improve erectile function. A small-scale study included 21 participants who saw improvements in ED score on the IIEF after three months of treatment with 120mg of a pine bark extract. Another study looking at Prelox, a branded combination of the two ingredients, found a steady increase in IIEF scores at two and three months compared to placebo.


L-lysine is an ingredient in Semenax that has a role in healthy sperm, but studies into the potential for lysine supplementation to improve semen parameters are lacking.

Catuaba Bark

Catuaba bark is an ingredient in Semenax that offers potential antioxidant activity. However, human studies into the substance are all but non-existent.

Epimedium Sagittatum Leaf

Epimedium sagittatum leaf is an ingredient in Semenax that has the potential to improve sexual health. However, the doses Semenax uses are far lower than the doses that studies indicate would be predictably influential.

While the individual ingredients in Semenax have some scientific research suggesting efficacy in this realm, the doses Semenax uses are often lower than the doses that studies indicate would be predictably influential. Taken together, they might be sufficient to make a difference for some men, especially combined with some of the better ingredients included at higher doses. With additional research into the ingredients themselves and into the supplement as a whole, we can hopefully make a more comprehensive recommendation in the future.

Semenax Price

At Semenax, the more you buy, the more you save. The company offers discounts for bulk purchases, but there is currently no subscription option available for added savings or convenience.

Semenax lists retail prices for its products, but the company typically has some kind of promotion going on that reduces those prices. In our experience, these promotions are always active, and they bring the product’s prices down to an average level among its competitors.

To help our readers save even more, Leading Edge Health has provided us with coupon codes that can be used to get extra discounts on Semenax products. These coupon codes can be applied during checkout on the Semenax website. Here are the details:

While Semenax may not be the most affordable supplement in its class, our coupon codes can help bring the price down to a more reasonable level.

Alternatives to Semenax

If Semenax is not the right choice for you, there are several other options to consider. Here are some alternatives to Semenax that you might want to explore:

Other Nutritional Supplements

Similar to Semenax, there are other nutritional supplements that aim to improve male sexual health. Here are some types of nutritional supplements that might interest you:

Male Enhancement Pills

Male enhancement pills contain various ingredients that aim to improve blood flow to the penis. They are also known as volume pills or testosterone boosters. You can learn more about male enhancement pills in our guide to the best male enhancement pills.

Volume Pills

Volume pills are supplements that aim to improve semen quantity and quality. They contain fewer ingredients related to blood flow and more related to semen quality. You can learn more about volume pills in our Volume Pills guide, which provides helpful comparisons between these supplements and male fertility supplements.

Testosterone Boosters

Low testosterone levels can cause several issues in the bedroom, including poor erectile performance, low libido, and infertility. Testosterone boosters aim to address this issue. However, they may not be helpful if your testosterone levels are normal. You can learn more about testosterone boosters in our testosterone booster guide.

Fertility Supplements

Fertility supplements may contain similar ingredients to testosterone boosters and volume pills, often in higher doses for similar prices. They are marketed toward men with less aggressive salesmanship than other product categories. However, you can explore them further in our dedicated guide to volume pills and male fertility supplements to see if they are right for you.

Prescription Medication

If you are looking to improve erectile performance, prescription medications like Viagra or Cialis and their generic equivalents may be more effective than Semenax or other male enhancement products. These treatments have undergone more scientific scrutiny than many of the ingredients found in male enhancement supplements.

Here are some highlights from our comprehensive guide to the best prescription ED medications and their available telemedicine providers:

Generic Tadalafil

Generic tadalafil (Cialis) is our preferred treatment overall due to its low cost and dosage flexibility. You can take it daily or as needed, and it will last in your system for up to 36 hours. We recommend men interested in generic tadalafil on an as-needed basis to look into BlueChew, a company that provides its medications in convenient chewable tablets. Men interested in daily tadalafil should check out Hims.

Generic Sildenafil

Generic sildenafil is a popular option, as it is therapeutically identical to Viagra but costs less. Unlike tadalafil, sildenafil can only be taken as needed, and it does not last in the system as long (6-8 hours). If you have never tried a prescription ED medication, BlueChew allows you to try sildenafil for free. Meanwhile, Hims offers sildenafil in a wider range of dose options.

There are a few other options that work in the same way as these two drugs (most prescription ED meds are PDE-5 inhibitors). These options are often newer and more precise in targeting PDE-5 and not other similar enzymes like PDE-6 or 11. That can reduce the risk of what are already rare side effects, but they might be better options if you experience issues with sildenafil or tadalafil.

In conclusion, there are several alternatives to Semenax that you can consider, including other nutritional supplements and prescription medication. We recommend exploring these options further to find the right treatment for you.
