Fact Checked
Highlights
- Erections rely on nitric oxide and healthy blood flow, so the strongest formulas focus on that pathway.
- L-arginine and L-citrulline have the most human research, and studies usually used 1,500 mg a day or more.
- Herbs like ginseng, maca and tongkat ali look promising, but most of the studies are small.
- Hidden prescription drugs have turned up in this category, so honest labels and third-party testing matter.
- PeakErect® took the top spot for its wide formula, steady feedback and low-risk guarantee.
Overview
Erection or maintenance issues and concerns about performance may help to impact confidence and intimacy. Stress, poor sleep, age-related changes and limited circulation can all be factors and sometimes, the anxiety of performing can make it more challenging.
That’s where we can help. We have compiled a list of the best supplements for erections, concentrating on formulas that are focused on the enhancement of blood flow, sexual stamina, libido and male performance. Numerous of these supplements consist of amino acids and herbal substances researched for its capability in the production of nitric oxide, circulation, and sexual function.
We have researched five widely-used formulas based on ingredient sources, ingredients and dosage transparency, safety, customer reviews, and formula quality. Explore our top recommendations to find an erection supplement that best matches your needs and preferences.
What Are Erection Supplements?
Erection supplements are over-the-counter products that are offered to improve blood flow, drive, stamina and sexual self esteem. Available in tablet, capsule, powder or gummy form. They do not work quite as quickly or intensely as prescription ED drugs, and are not approved for the treatment of ED.
Most formulas are based on a shortlist. The body can produce nitric oxide (NO) with the help of amino acids like L-arginine and L-citrulline. Maca, Panax ginseng, tongkat ali (also known as Long jack) and tribulus are herbs used for drive and stamina. Zinc can help fill in nutrition gaps, and certain formulas are even flavored with caffeine to provide stimulation.
As well as the ingredients, the quantity is important. Research on arginine and citrulline has found doses around 1,500 mg/day or higher to be effective, and many supplements have significantly lower amounts. The length of the list of ingredients does not necessarily indicate the strength of the product, it is the dose, quality of extract and label that matters.
How We Researched and Selected the Best Supplements for Erections?
Methodology
Every product went through the same review. Ingredient lists were checked against published studies, doses were compared with the amounts used in research, and verified customer feedback was read for patterns, good and bad. Where tester accounts were available, they were weighed next to the label review.
Formulas with clear labels, familiar ingredients and doses close to what studies used scored higher. Price was weighed against what each serving delivers, since a cheap bottle with a token dose isn’t much of a bargain. And products that promised instant results or size gains lost points.
Criteria for Evaluation
- Formula Strength: Whether ingredients and doses line up with what published research used.
- Ingredient Transparency: Clear labeling of every active ingredient, not a vague “proprietary blend.”
- Safety and Tolerability: Stimulant content, known interaction risks, GMP manufacturing and third-party testing.
- Customer Feedback: Patterns across verified reviews and tester accounts.
- Value for Money: Monthly cost next to what the serving delivers, plus the strength of the money-back guarantee.
Expert’s Advice on Supplements for Erections
Urologist Dr. Daniel Shoskes has a blunt view of treating erection problems on your own with herbal products. He told NBC News that erectile dysfunction should prompt a doctor’s appointment, because it can be an early red flag for other problems such as heart disease.
That advice shapes how this list should be read. Supplements can be a sensible add-on for mild, occasional trouble, but they don’t replace a checkup. With that in mind, our Health Insiders research team’s top pick is PeakErect®, which covers circulation, drive, stress and stamina in one formula. Prefer a shorter label? WOWMD® Perform Max keeps things to four ingredients. And if you want energy and focus alongside blood flow support, Performer 8® is worth a look. Full ingredient breakdowns, pricing and feedback notes are below.
Why Trust Health Insiders?
It’s not easy to choose a supplement that fits into this category. Labels shout, and the research whispers. So the legwork gets done here first.
Each product on this page went through three checks: ingredient research against published studies, a look at verified customer feedback, and a review of how openly the brand shows its formula and doses. Claims come from clinical research and reputable medical sources instead of brand copy, and safety warnings get as much space as the benefits.
The goal isn’t to bury you in milligrams and citations. At Health Insiders the list is updated as formulas, prices and research change to help you identify those that are worthy of narrowing the field with clear reasons.

Erections don’t depend on one thing. Blood flow, hormones, stress and energy all feed in; that’s what makes a broad formula like this one appealing. Most competitors stop at three or four ingredients, and PeakErect® keeps going.
Expert Evaluation
Reviewed by the Health Insiders Nutrition Research Team
Our editors went through the full ingredient list, the published research behind L-Arginine, Longjack and Maca, the manufacturing standards, how open the label is, and feedback from real users.
Our Findings
The most significant advantage PeakErect® has to offer is its range. The ingredients all align with the primary factors that impact an erection: circulation, hormone support, stress and energy. The L-Arginine amount (250 mg) is modest next to the doses used in trials, so the appeal is the breadth of the blend, not a heavy hit of any single ingredient. And that suits a gradual routine well, since it’s built for steady daily use, not one-off spikes.
What Our Tester Says
Our tester Joe Dolt tried PeakErect® as part of both his workout routine and bedroom performance. Already familiar with pre-workout supplements, Joe recognized several ingredients commonly associated with energy and blood-flow support.
During testing, he noticed more energy at the gym and felt the supplement also supported his performance in the bedroom. He compared the workout experience to the “pump” he associates with L-Arginine and highlighted Maca, Longjack, Zinc, and Ginseng in the formula.
His main concern was the tablet size, which he found relatively wide. Overall, Joe reported a positive experience, while noting that results may differ between users.

Where PeakErect® goes wide, Perform Max stays tight. Nothing on the label is there for show, and each ingredient has a job you can explain in a sentence.
Expert Evaluation
Reviewed by the Health Insiders Nutrition Research Team
Our editors looked at the four-ingredient formula, the research behind L-Arginine, Maca and Longjack, manufacturing details, label clarity and verified customer feedback.
Our Findings
Focus is what makes Perform Max work. It sticks to four ingredients men tend to recognize and explains what each one is for. L-Arginine handles the nitric oxide side; Maca and Longjack are the traditional vitality picks; Zinc rounds out the mineral base. The tradeoff is range, since a short list can’t cover as much ground as PeakErect®. But for men who want to keep things simple, that’s the whole point. The brand’s own timeline is patient too, describing benefits that build over one to six months, which is a realistic way to talk about a supplement.
What Our Tester Says
Peter, 36, had spent years dealing with low energy, low confidence, and little desire, leaving him frustrated and disappointed. After trying several supplements without success, he felt like he was wasting money. A friend suggested Perform Max, but Peter first read customer reviews before ordering one bottle. He followed the directions and liked the natural ingredient blend. About a month later, he noticed a clear improvement in his energy, desire, and overall performance. More importantly, his confidence started returning. Peter says he feels like a better version of himself and considers Perform Max a game changer worth trying.

- Includes L-Arginine and L-Lysine for circulation and recovery support.

Performer 8® leans toward energy as much as performance. Its eleven-ingredient formula centers on KSM-66 Ashwagandha, L-Arginine and SenActiv, then rounds things out with minerals, B vitamins, L-Lysine and caffeine. That makes it a natural match for men whose afternoon slump drags down drive as well as focus, and who want one all-in-one capsule in place of several separate bottles.
- Form: Capsule
- Type: Supplement
- Benefit: Supports energy, stamina, circulation, focus and everyday male vitality
- Brand: Performer 8®
- Active Ingredients: KSM-66 Ashwagandha, L-Arginine, SenActiv, Magnesium Oxide, Vitamin C, Zinc, Vitamin B6, Copper Sulfate, Folic Acid, L-Lysine, Caffeine

- 60-day money-back guarantee and discreet shipping
Cons
- Three capsules a day, with 90 capsules per bottle
- Caffeine is on the ingredient list, so men who are sensitive should check the label first
- Higher price per bottle than some picks here; bigger bundles cost less per month but need a larger upfront spend
Real difference after two months
I was skeptical at first, but after two months I’ve noticed a real difference. My energy lasts much longer throughout the day, no more dragging in the afternoon. Things feel stronger and more consistent for my wife too. I feel more like myself again and a better husband overall. No side effects, just natural support. – Garry P.
More drive after about a week
My husband (47) and I wanted something natural. After about a week he had more drive and initiative. He lasts longer and seems to have more energy in the evenings. Our connection feels renewed, like we’re closer again. It’s made a big difference for both of us. – Stacy P.
Performer 8® is the best fit for men who want energy and focus to sit alongside blood flow support. The eleven-ingredient formula, the branded KSM-66 Ashwagandha and the 60-day money-back guarantee give it real appeal. Just keep the caffeine in mind if you’re sensitive to it.
Why It Earned a Spot on Our List
Every product faces the same checks, and here’s how Performer 8® held up.
What stood out about this product to us
- Eleven named ingredients across energy, stress, circulation and recovery

- L-Arginine and L-Lysine pairing
- Soy-free, gluten-free and vegan, made in a GMP-certified facility
- 60-day money-back guarantee* and discreet packaging
Where PeakErect® and Perform Max focus on circulation and drive, Performer 8® pushes harder on energy and focus. That mix is what makes it appealing for men whose day drags by mid-afternoon; but the caffeine is worth knowing about before you buy.
Expert Evaluation
Reviewed by the Health Insiders Nutrition Research Team
Our editors reviewed the ingredient list, the research behind the main ingredients, the manufacturing standards, label clarity and the customer feedback published by the brand.
Our Findings
Performer 8® works like a nutrient-plus-energy formula with a circulation angle. The ingredient panel is clear, and the mix of ashwagandha, amino acids, minerals and B vitamins makes sense for men dealing with stress and fatigue. Caffeine is what gives it its daytime lift; it’s also what separates it from the stimulant-free options above. That’s a fair trade for some men and a dealbreaker for others.
What Our Tester Says
Our tester, Sam, went through Performer 8® the way a careful buyer would, starting with the supplement facts panel and directions. Eleven ingredients are named on the label, including KSM-66 Ashwagandha, L-Arginine, L-Lysine and SenActiv, alongside Zinc, Magnesium and B vitamins. The serving is three capsules a day, and a bottle holds 90, providing a one-month supply.
Sam noted that the capsules can be taken with a meal or on an empty stomach, making them easy to fit into a routine. Two things stood out to him. Every ingredient is named on the label, which he appreciated. However, caffeine is also included, which may matter for anyone sensitive to stimulants or already consuming plenty of coffee.
Ingredient Quality 4.5/5
Sam noted that branded ingredients such as KSM-66 Ashwagandha and SenActiv made the formula feel more thoughtfully put together.
Formula Transparency 4.4/5
Sam appreciated that all eleven ingredients are clearly named on the label, making the complete formula easier to understand.
Safety Profile 4.3/5
Sam liked that it is vegan, soy-free and gluten-free, though he noted the caffeine content may concern sensitive users.

Stallion X – Best Erection Gummy
Our Rating
Stallion X is a male enhancement gummy sold under the StallionX and StalliOnX names. Ingredients listed across its pages include L-Arginine, Tribulus Terrestris, Tongkat Ali, Maca Root, Ginseng Extract, Zinc and Vitamin B12, all aimed at blood flow, stamina and libido. The gummy format is easy to take. But labeling changes from seller to seller, added sugar and some big marketing promises make it a product to research carefully before buying.

Stallion X Pros & Cons
Pros

- Price swings widely by seller, from about £39.70 on Amazon UK to £69.95 for a single bottle on another site
- Some sites use bold claims about instant results or size gains that no supplement research supports
Stallion X Customer Reviews
Results Were More Gradual Than I Expected
I used StalliOnX consistently for several weeks. I noticed slightly better energy, but the performance changes were modest compared with the stronger claims advertised online. – Marcus H.
Convenient Gummies But Benefits Felt Quite Limited
The gummies were easy to take and fit my routine well. However, I didn’t notice a major difference in stamina or confidence after regular use. – Daniel R.
Summary: Stallion X gummies are easy to take and use familiar ingredients, but unclear labeling, sugar content and inflated marketing on some sites hold them back. Anyone tempted should confirm the exact formula on the label of the version they buy, and stick with a seller that shows a full supplement facts panel.

How to Choose the Best Supplement for Erections?
- Ingredient Quality: Look for ingredients with human studies behind them, such as L-arginine, L-citrulline, Panax ginseng and tongkat ali. Be wary of long lists where nothing is dosed clearly.
- Effective Dosage: Trials on arginine used 1,500 to 5,000 mg a day. The citrulline study used 1.5 g a day. Check whether the label gets anywhere close, or whether the amounts are tucked inside a “proprietary blend.”
- Stimulant Content: Some formulas add caffeine. That’s fine for some men, but a problem if you’re sensitive to it, have a heart rhythm issue or already take stimulants.
- Form and Convenience: Tablets, capsules and gummies all exist. Gummies are easy to swallow but can add sugar, and capsules tend to keep the label cleaner.
- Safety and Third-Party Testing: Choose brands that show GMP manufacturing and third-party testing. And steer clear of “miracle” products with no full label. The FDA has found sildenafil in several sex supplements and says it can’t test every product in this category, so caution is part of buying.
- Money-Back Guarantee: Sixty days gives you time to judge results, since most benefits build over weeks. Read the fine print, because many guarantees cover only a first single-bottle purchase.
- Marketing Red Flags: “Instant results,” “guaranteed size gains” and “zero side effects” are promises no supplement can keep.
Common Ingredients Found in the Best Supplements for Erections
L-Arginine
L-arginine is an amino acid the body uses to make nitric oxide. An NIH study of 10 randomized trials covering 540 men found that 1,500 to 5,000 mg a day improved mild to moderate ED compared with placebo, without severe side effects.[1] A separate trial gave 6 g a day for three months and saw better erectile function scores, though ultrasound blood flow gains showed up only in men with milder problems.
L-Citrulline
L-citrulline is converted into L-arginine in the body and avoids some of the breakdown that limits oral arginine. In a PubMed study of 24 men with mild ED, 1.5 g a day for a month moved half of them to normal erection hardness, compared with about 8% on placebo.[2]
Longjack (Tongkat Ali)
Longjack, also called tongkat ali or Eurycoma longifolia, is a Southeast Asian root. A systematic review and meta-analysis of clinical trials linked it to higher total testosterone in men.[4]
Ginseng
Panax ginseng is the best-studied herb on this list. A Cochrane systematic review of nine placebo-controlled trials found a small effect on erectile function scores and better self-reported ability to have intercourse.[5] Siberian ginseng, used in PeakErect®, is a different plant, mainly used as an adaptogen for stress and stamina.
Zinc
Zinc is an essential mineral involved in normal hormone and immune function. It matters most for men who run low, so it works best as a supporting ingredient rather than the main event.
Benefits of Supplements for Erections
Better Blood Flow Support: Ingredients like arginine and citrulline feed the nitric oxide pathway that helps blood vessels relax.
Firmness and Confidence: For mild trouble, some men notice firmer, more reliable erections over several weeks.
Steadier Energy and Stamina: Many formulas add ingredients meant to ease fatigue, which can show up in the bedroom as well as the gym.
Stress Support: Adaptogens such as ashwagandha and Siberian ginseng aim to take the edge off daily stress, and stress is a common piece of the puzzle.
Simple Daily Routine: Most products need only one to three servings a day, so they slot into a routine you already have.
Libido and Desire Support: Ingredients such as maca, ginseng, and tongkat ali are commonly included to support sexual desire and overall male vitality.
Nutritional Support: Minerals such as zinc can help maintain normal hormone function and general wellness, particularly when dietary intake is inadequate.
Everyday Vitality: Some formulas combine amino acids, botanicals, and essential nutrients to support overall vitality alongside their more targeted sexual wellness benefits.
How Do Supplements for Erections Work? What Does Science Say?
An erection starts in the brain and finishes in the blood vessels. Nitric oxide tells the smooth muscle in the penis to relax, and that lets blood flow in. Amino acids like arginine and citrulline are what give the body more raw material to make that molecule.
The human data are encouraging, though limited. The arginine meta-analysis found benefit in men with mild to moderate ED.[1] The citrulline study was small and short, but half the men improved. Herbs have a weaker record; a 2018 review of 24 trials concluded that more and better research is needed before herbal products can be recommended for ED.
And there’s the dose gap. Research used 1,500 mg a day or more of arginine or citrulline, while some multi-ingredient formulas contain a fraction of that. None of this means a capsule works overnight. Most studies ran for weeks or months, which matches the slow-build pattern users describe.
Are Supplements for Erections Safe to Use?
Most healthy adults tolerate the main ingredients well when they follow label directions. L-arginine is generally considered safe, and the most common side effects are stomach upset, bloating, diarrhea and headache.
Quality is the bigger risk. Choose brands with third-party testing and full labels, and avoid anything sold with wild promises or no supplement facts panel. And if you take prescription medication or have a medical condition, consult a healthcare professional before starting.
Side Effects, Interactions, and Who Should Not Take Them?
Possible Side Effects:
- Nausea, stomach pain or diarrhea
- Bloating
- Headache
- Lightheadedness if blood pressure drops
- Jitters or trouble sleeping with caffeinated formulas
Interactions to Watch: L-arginine may interact with blood pressure drugs, nitrates, blood thinners and diabetes medications. Nitrates and prescription ED drugs can combine to cause a dangerous blood pressure drop.
Who Should Be Careful:
- Anyone who has had a recent heart attack, since L-arginine isn’t recommended over concerns about the risk of death
- Men with heart disease, high blood pressure, kidney problems or diabetes
- People with a history of cold sores or genital herpes, since too much L-arginine may activate the virus
- Anyone with asthma or allergies
- Men under 18
- Anyone taking nitrates, ED medication, blood thinners or blood pressure drugs
Who Should Consider Using Supplements for Erections?
- Men With Mild, Occasional Trouble: Most research looked at mild to moderate ED, so that’s where supplements make the most sense.
- Men Over 40 Noticing a Slower Response: Blood flow and hormones shift with age, and gentle daily support can be a reasonable starting point.
- Men Under Heavy Stress: Formulas with adaptogens may suit men whose stress is a bigger factor than blood flow.
- Men Who Prefer a Non-Prescription Route: Supplements can be an option for men not ready for prescription medication, as long as a doctor has ruled out health problems first.
- Men Who Like Simple Routines: Short, focused formulas are easier to stick with, and consistency is what most benefits depend on.
Tips for Getting the Most Out of Your Supplement
- Give It Time: Studies run for weeks to months, so judge a product after at least four to six weeks of steady use.
- Follow the Label: More isn’t better, and it can raise the odds of side effects.
- Take It Consistently: Same time every day works best, ideally with food if your stomach is sensitive.
- Move and Sleep More: Regular exercise and good sleep support circulation and hormones.
- Cut Back on Alcohol and Quit Smoking: Both hurt blood vessel health.
- Track Your Progress: A quick weekly note helps you see whether anything is really changing.
- Consult a Healthcare Professional First: This matters most if you take medication or have heart, blood pressure or blood sugar concerns.
Foods and Habits That Support Healthy Blood Flow
- Leafy Greens and Beets: Rich in dietary nitrates, which the body can turn into nitric oxide.
- Watermelon: A natural source of citrulline, though in smaller amounts than supplements.
- Nuts and Seeds: Walnuts, almonds and pumpkin seeds supply arginine.
- Fatty Fish: Salmon and sardines support heart and vessel health.
- Berries and Pomegranate: Packed with antioxidants that help protect blood vessels.
Pair those with regular walking, strength training and a healthy weight, and you’ve covered the basics that support blood flow. A targeted supplement can then add a little extra on top.
Final Verdict
Erection problems are rarely about one thing, and no capsule fixes all of it. The best supplements support blood flow and stress with honest labels and realistic promises; the worst hide their doses and oversell.
PeakErect® took the top spot for its wide formula and steady feedback. WOWMD® Perform Max is the pick for a short, simple label, and Performer 8® suits men who want energy and focus alongside circulation support. The WOWMD® L-Citrulline & L-Arginine Stack is a clean choice for a focused amino acid approach. Stallion X is easy to take but comes with too many open questions.
If trouble in the bedroom keeps happening, book a checkup too. It can be an early sign of something else, and the earlier that gets caught, the better.
Frequently Asked Questions
Q: Do supplements for erections actually work?
A: Some ingredients, mainly L-arginine and L-citrulline, have small human studies showing benefit in mild to moderate ED. Herbal ingredients have weaker evidence, and no supplement works for everyone.
Q: How long before I notice results?
A: Most men need four to six weeks of steady use. Some formulas describe benefits building over several months.
Q: Can I take them with Viagra or Cialis?
A: Not without medical advice. Both can lower blood pressure, and adding L-arginine or a similar ingredient may push it too low. Consult a healthcare professional first.
Q: What’s the difference between L-arginine and L-citrulline?
A: L-arginine is the direct building block for nitric oxide. L-citrulline is converted into arginine in the body and may hold up better after digestion.
Q: Are they safe for daily use?
A: Most healthy adults tolerate them well at label doses. Long-term data are limited, so a check-in with a doctor is wise.
Q: Can I use them if I have heart disease or high blood pressure?
A: Talk to a healthcare professional first. Some labels, like Perform Max, specifically advise caution for men with high blood pressure or heart problems.
Q: What causes erection problems in the first place?
A: Common causes include poor blood flow, low testosterone, stress, medications, diabetes, heart disease, smoking and heavy drinking. A doctor can help sort out which apply.
Q: Do supplements work for severe ED?
A: Unlikely. Research on arginine focused on mild to moderate ED, and severe cases usually need medical treatment.
Q: Is a higher dose always better?
A: No. Stick to label directions, and look for products whose doses match research instead of chasing big numbers.
Q: Which is the best supplement for erections?
A: PeakErect earned the top spot for its wide formula, steady feedback and 60-day guarantee. Performer 8® and Perform Max are strong alternatives depending on what you want from a formula.
