A stroll through any supplement aisle makes sexual health look like something you can fix with a single pill. Bright labels promise “peak performance,” “natural virility,” and “testosterone support.” It is tempting to toss a bottle into your cart and hope for the best.
Sexual health supplements for men are a huge business, but the science behind them is often thin or completely missing. If you are considering trying one, it helps to understand what these products can and cannot do, what the risks are, and what actually does improve sexual function.
Understand what sexual health supplements claim to do
Most sexual health supplements for men are marketed around a few common promises. Labels often suggest that they can:
- Improve erections
- Increase libido
- Boost testosterone
- Enhance stamina or endurance
The problem is not just that these claims are bold. It is that they are rarely backed by solid research.
A review of top selling sexual health supplements found little or no evidence that they actually improve sexual performance in men (Harvard Health Publishing). In other words, much of what you are paying for may be packaging, not proven results.
Why scientific evidence matters
When you hear that a supplement is “natural” or “herbal,” it is easy to assume it is automatically safe and effective. In reality, many products marketed for erections and performance have never gone through rigorous testing.
Researchers have found that most over the counter sexual health supplements for men have not been scientifically studied at all, and many appear to work no better than a placebo (Harvard Health Publishing).
Prescription medications for erectile dysfunction, like sildenafil (Viagra), tadalafil (Cialis), vardenafil, and avanafil, have gone through extensive trials as PDE5 inhibitors. Their benefits and side effects are well documented. By contrast, many herbs and blends that make similar promises have not been studied with the same care (Mayo Clinic).
That does not mean every supplement is useless. It does mean you should be skeptical of big claims based on tiny or nonexistent studies.
Common ingredients and what they actually do
Many men’s sexual health supplements use similar ingredient lists, often bundling several herbs, vitamins, and amino acids into one capsule. Here is what you are most likely to see and what is known so far.
Important: None of the ingredients below should be started without speaking to a healthcare professional, especially if you have heart disease, high blood pressure, or take prescription medications.
L‑arginine
L‑arginine is an amino acid your body uses to make nitric oxide, which helps relax blood vessels. In theory, this could support better blood flow to the penis.
In practice, evidence that L‑arginine meaningfully improves erections on its own is limited. Harvard experts note that while it has a real biological role in blood vessel relaxation, benefits for erectile function are unproven, and it may be risky if you have heart disease or low blood pressure (Harvard Health Publishing).
Yohimbe or yohimbine
Yohimbe is an African tree bark, and yohimbine is its active chemical. Some supplements include it as a “natural” way to increase blood flow to the penis.
Yohimbine can stimulate the nervous system and promote blood flow, but it is far from gentle. It is linked to side effects like high blood pressure, headaches, fast heart rate, anxiety, and insomnia (Harvard Health Publishing; Mayo Clinic). You are often warned to use it only with close medical supervision, if at all.
“Testosterone boosters”
You will also see plenty of “T booster” or “testosterone support” formulas. These often contain a long list of herbs, vitamins, and minerals. The marketing implies that more testosterone will fix low sex drive, energy, and erectile issues.
A 2020 study looked at 50 popular testosterone booster supplements. It found:
- 90 percent claimed to increase testosterone
- Only 24.8 percent of the individual ingredients had any published data showing they might raise testosterone with supplementation
- 10.1 percent of ingredients actually had data suggesting they could lower testosterone
- 61.5 percent had no published scientific data on testosterone effects at all (World Journal of Men’s Health)
On top of this, many of these products contained huge doses of vitamins and minerals. The median amounts were over 1,200 percent of the Recommended Daily Allowance for vitamin B12, over 800 percent for vitamin B6, and 272 percent for zinc, and some products exceeded upper tolerable intake levels for zinc, vitamin B3, and magnesium (World Journal of Men’s Health).
So not only are the claims shaky, some formulas may actually push you into unsafe territory.
Other herbs and blends
You might also see:
- Horny goat weed
- Ginseng
- Maca root
These herbs are often included based on traditional use or small early studies. Scripps Health notes that while they are common in sexual health supplements, their safety and effectiveness remain unclear without medical supervision (Scripps Health).
Natural does not mean risk free. Herbal ingredients can interact with medications, affect blood pressure or blood sugar, and trigger allergic reactions.
Hidden risks and safety concerns
One of the biggest issues with sexual enhancement supplements is not on the label at all.
Regulators have repeatedly found undisclosed prescription drugs in products sold as “herbal Viagra.” Some supplements contained hidden PDE5 inhibitors, the same type of drug used in Viagra, Cialis, and similar medications. These unlisted ingredients can trigger dangerous side effects, especially if you also take nitrates or certain heart medications (Harvard Health Publishing; Mayo Clinic).
The FDA has banned many of these products, but some still make it to store shelves and websites. Because supplements do not have to go through the same premarket testing as prescription drugs, regulators often only step in after harm is reported (Mayo Clinic; Scripps Health).
Scripps Health warns that men’s sexual health supplements can also contain dangerous impurities, cause allergic reactions, and interact with medications, and that they are much less regulated than prescription options (Scripps Health).
What actually helps sexual function
While many supplements fall short, you are not stuck with “nothing works.” A number of strategies and treatments have better evidence behind them.
Address lifestyle factors
Lifestyle has a direct effect on sexual health. Changes that improve your heart and metabolic health also support better erections and libido.
Harvard experts point out that the following habits can improve sexual function, often more reliably than supplements (Harvard Health Publishing):
- Losing excess weight
- Exercising regularly
- Quitting smoking
- Limiting alcohol intake
- Eating a nutrient dense, balanced diet
Erections depend on healthy blood vessels and nerves. Anything that protects your cardiovascular system, such as brisk walking, strength training, or cutting back on ultra processed foods, also protects your ability to maintain an erection.
Treat underlying medical conditions
Erectile dysfunction and low libido are often symptoms, not stand alone problems. They can be linked to:
- Heart disease
- High blood pressure
- Diabetes or prediabetes
- Hormonal imbalances
- Depression or anxiety
- Medication side effects
Doctors at Scripps Health strongly encourage men with sexual health concerns to see a healthcare provider instead of self diagnosing and self treating with supplements. Adjusting medications, treating heart risk factors, or managing mood and stress can significantly improve sexual function more safely and effectively than unproven pills (Scripps Health).
Consider proven medical treatments
If you are dealing with erectile dysfunction, there are well tested medical options. Prescription PDE5 inhibitors such as sildenafil, tadalafil, vardenafil, and avanafil have robust evidence behind them and are recommended by major medical organizations (Mayo Clinic).
For some men, additional treatments like hormone therapy, vacuum devices, injections, or counseling focused on sexual function and relationships may be appropriate. A healthcare professional can help match you with the safest and most effective option for your situation.
Mayo Clinic experts specifically advise against using ED supplements that lack proven benefits and may cause harm, particularly if you have conditions like heart disease or diabetes (Mayo Clinic).
How to evaluate a supplement before you try it
If you are still considering a sexual health supplement, slowing down and asking a few questions can protect your wallet and your health.
-
What does the evidence say?
Look for credible sources that discuss the ingredient, not just marketing claims. If most of the support comes from animal studies, very small trials, or anecdotes, the effect in real life is probably uncertain. -
Is the dose reasonable?
Mega doses of vitamins and minerals are not always better. As the testosterone booster study showed, many products far exceed recommended daily allowances and sometimes even safe upper limits (World Journal of Men’s Health). -
Could it interact with your medications or conditions?
If you have heart disease, high blood pressure, kidney disease, liver issues, or take daily prescriptions, you should not start any supplement without medical advice. -
Does the product feel like a shortcut?
If the main appeal is that it lets you avoid seeing a doctor or making lifestyle changes, that is a red flag. Erections are often early warning signs for broader health issues. Numbing that signal with a supplement can delay important care. -
Have you talked with a professional?
Bring the bottle, or at least a clear photo of the label, to your appointment so your clinician can review the actual ingredients and doses.
Key takeaways you can act on today
Sexual health is personal, and it is completely understandable if you want an easy fix. The reality is more nuanced.
Most over the counter sexual health supplements for men do not have strong evidence behind them. Some may act mainly as placebos. Others may carry real risks, from excessive vitamin doses to undisclosed prescription drugs that can interfere with heart medications (Harvard Health Publishing; Mayo Clinic; Scripps Health).
If you want to support your sexual health, you can:
- Focus on lifestyle changes that improve your heart and metabolic health
- Get evaluated for underlying conditions that may be affecting erections or libido
- Discuss proven medical options with a healthcare professional
- Approach any supplement with skepticism and informed caution
You do not have to figure all of this out alone. Scheduling an honest conversation with your doctor, even if it feels awkward, is one of the most powerful steps you can take. It moves you away from guesswork and marketing claims and toward a plan that is tailored to your body, your health, and your goals.
