Nitric Boost Ultra Reviews and Complaints (2026): Ingredients, Price, Refund

The jar says Nitric Boost Ultra; the website calls it Nitric Boost. It is the same product.

Nitric Boost Ultra is a daily powder for men that aims to support erections by raising nitric oxide, the gas that lets blood vessels relax and fill. The official order page names eight ingredients: beet root powder, L-arginine, L-citrulline DL-malate, niacin, horny goat weed, ginkgo biloba, dong quai and D-aspartic acid. You take one scoop a day in water. It is sold through trynitricboost.me at $49 to $69 per jar as a one-time payment, with a 60-day money-back guarantee. This review covers the evidence for each ingredient, the price, the refund fine print and, most important, the safety points.

First, a word about erectile problems

Erection trouble is common and it gets more common with age, but it is not just an age thing. The blood vessels that supply the penis are small, so they often show circulation problems earlier than the heart does. That is why doctors treat new erectile dysfunction as a reason to check blood pressure, cholesterol, blood sugar and heart health. Diabetes, smoking, some medicines, low testosterone, stress and depression can all play a part, and several of these are very treatable.

So before anything else: if this is new for you, talk to a doctor. It is a short, normal conversation for them, and it may catch something important. Nitric Boost is a dietary supplement, not a treatment for erectile dysfunction.

What is inside Nitric Boost?

The order page lists eight ingredients and what the brand says each one does. Here they are next to what the research actually supports.

The page calls it a proprietary blend and does not give the amount of each ingredient. That matters here more than usual, because the arginine and citrulline studies used several grams a day. A 30-serving jar has room for a meaningful dose, but you can only confirm it on the label. Check the Supplement Facts panel when your jar arrives.

How nitric oxide supplements are supposed to work

When you are aroused, nerves release nitric oxide in the penis. Nitric oxide triggers a messenger called cGMP, which relaxes the blood vessels so they fill with blood. An enzyme called PDE5 breaks cGMP down; drugs like sildenafil (Viagra) work by blocking that enzyme. The order page presents cGMP as a new "manhood molecule" discovery, but this pathway has been understood since the 1990s and is the basis of every ED pill on the market.

Supplements like Nitric Boost take a different route: they supply the raw materials for nitric oxide. L-arginine is the direct building block; L-citrulline is turned into arginine by the kidneys and raises blood arginine more steadily; beet root adds dietary nitrates, which the body can also convert. It is a reasonable approach, but it is gentler than a prescription drug, and it depends on your blood vessels being able to respond.

Every ingredient, up close

Here is every active ingredient on the label, what it actually is, and what research does and does not show. The order page lists the ingredients but not the amount of each, so for every card we can only say what the studied dose was, not whether the scoop reaches it.

L-arginine

Listed on the order page; no label, amount not disclosed

The amino acid the body uses directly to make nitric oxide (pictured: mixed nuts, a common food source of arginine). Several placebo-controlled trials in men with ED, usually at 2.5 to 5 grams a day, point to modest improvements in mild to moderate cases, best in men whose nitric oxide levels were low; the trial the order page cites is one of these. High doses commonly cause bloating and stomach upset.

L-citrulline DL-malate

Listed on the order page; no label, amount not disclosed

An amino acid named after the watermelon, its richest food source (pictured: watermelon slices). The kidneys turn it into arginine, raising blood arginine more steadily than arginine itself. A small 2011 trial gave men with mild ED 1.5 grams a day for a month and found more of them reported harder erections than on placebo; it has not been confirmed in large studies. The malate form means part of each gram is malic acid, not citrulline.

Beet root powder

Listed on the order page; no label, amount not disclosed

Beets supply dietary nitrates that the body converts to nitric oxide. They reliably help exercise performance and blood pressure in studies that used nitrate-rich juice or concentrated powder, but there are no trials for erections, and whether a scoop holds a meaningful amount is unknown.

Niacin (vitamin B3)

Listed on the order page; no label, amount not disclosed

A B vitamin found in many foods (pictured: peanuts, a common food source of niacin). One trial suggested a benefit in men with ED and high cholesterol, at drug-level doses. It commonly causes skin flushing, interacts with some statins and, at high doses, can affect the liver, according to the NIH Office of Dietary Supplements.

Horny goat weed

Listed on the order page; no label, amount not disclosed

A traditional Chinese herb whose compound icariin blocks PDE5, the Viagra target, in lab and animal studies. That has not been shown in people, and the page does not say how much icariin is in the scoop.

Ginkgo biloba

Listed on the order page; no label, amount not disclosed

An extract of the fan-shaped leaves of one of the oldest living tree species. It was studied for sexual problems caused by antidepressants with mixed results. NCCIH notes it can raise bleeding risk, which matters if you take warfarin, apixaban or daily aspirin.

Dong quai (Angelica sinensis)

Listed on the order page; no label, amount not disclosed

A root from traditional Chinese practice, used mostly in formulas for women. There is little research in men, and it has been reported to strengthen the effect of warfarin and to increase sensitivity to sunlight.

D-aspartic acid

Listed on the order page; no label, amount not disclosed

An amino acid involved in hormone signaling. Early work suggested it could raise testosterone, but later studies in healthy and trained men mostly found no rise, so the evidence is mixed at best.

How to take Nitric Boost

The FAQ says one scoop a day with a glass of water, or mixed into a smoothie or tea. Many men will prefer taking it at the same time each day rather than only before sex, because the arginine and citrulline studies used daily dosing over weeks. If you notice flushing or warmth in your face, that is usually the niacin; it tends to fade, but tell your doctor if it bothers you. Do not exceed the label dose.

How much does Nitric Boost cost?

The official order page sells three packages, each a single charge. The FAQ states there are no hidden fees or subscriptions.

Prices as listed on the official order page when we checked. They change from time to time, so the checkout page is the final word.

About shipping: the order page shows shipping added to the 1-jar package and free US shipping on 3 and 6 jars. The shipping page lists 5 to 7 working days in the US, and $19.99 with 10 to 15 working days for Canada, the UK, Australia, Ireland, New Zealand and South Africa. The 3 and 6-jar packages include two e-books: The Nitric Boost Blueprint and Marathon Man Stamina. Check the total on the checkout page before paying.

How the 60-day guarantee works

Every order from the official Nitric Boost store is covered by a 60-day money-back guarantee, and it is a one-time payment with no subscription or auto-shipment.

You have 60 days to ask for a refund, and the FAQ says it applies even if you used every scoop. Call 1 (814) 885-4823 (Monday to Friday) or use the email on the contact page, then send the jars to Adem Naturals, 285 Northeast Ave, Tallmadge, OH 44278, USA. Two things to know:

• You pay return shipping. The refund page also says you can refuse the package on delivery and it will be sent back.
• Phone support is listed for weekdays only, so do not wait until the last weekend of your 60 days.

Who should talk to a doctor before taking Nitric Boost?

• Anyone taking nitrate heart medicines such as nitroglycerin or isosorbide: products that raise nitric oxide can add to their blood-pressure-lowering effect.
• Men using sildenafil, tadalafil or similar ED drugs: combining them with L-arginine, citrulline and beet nitrates may drop blood pressure further. Ask your doctor before stacking.
• Anyone on blood pressure medication, or with low blood pressure, for the same reason.
• Anyone on blood thinners such as warfarin, apixaban or daily aspirin: ginkgo and dong quai can add to bleeding risk. Stop them before surgery.
• People taking cholesterol medicine or with liver problems: niacin interacts with some statins, and high doses can affect the liver.
• Anyone with herpes cold sores: some doctors advise caution with high-dose arginine.

Common side effects of these ingredients include flushing (niacin), stomach upset and bloating (arginine), headache and a drop in blood pressure. Stop and get advice if you feel dizzy or faint.

What to realistically expect

Nitric oxide supplements work gradually, if they work for you. In the trials, men took arginine or citrulline daily for one to three months before judging. A fair approach is to see a doctor first, take one scoop daily for six to eight weeks without changing anything else, and note how often things go the way you want. Men with mild, occasional problems are the most likely to notice something; men with diabetes, heart disease or severe ED usually need medical treatment. Decide before day 60 so you can still use the guarantee.

Our verdict

Nitric Boost Ultra gets the science of erections right and includes the two nutrients with the best supplement evidence for mild ED. It is convenient, priced in line with the category and backed by a refund that covers empty jars. Its weaknesses are a label that hides the doses, marketing that dresses up old science as a breakthrough, and real interaction risks with heart and ED medicines. If your doctor has ruled out a medical cause and you want to try a nitric oxide approach, it is worth considering from the official site.

Your doubts, answered honestly

Is Nitric Boost a scam?

It is a real product sold from trynitricboost.me, with a one-time payment, a weekday phone line (1 (814) 885-4823), a physical returns address in Tallmadge, Ohio and a 60-day guarantee that even covers empty jars. What we cannot verify are the doses, because there is no Supplement Facts panel on the site, and the "manhood molecule discovery" is old science dressed up as new.

Why does it cost $49 to $69 a jar?

A jar is a 30-day supply, so you pay $49 to $69 a month depending on the package, and the single jar ($69 plus shipping) is the cheapest way to try it. Plain L-arginine or L-citrulline powders are usually much cheaper per gram, and they print the dose, which is the main thing this product does not do.

Will it work for me?

Men with mild, occasional erection problems are the most likely to notice something, and in the trials men took arginine or citrulline daily for one to three months before judging. Men with diabetes, heart disease or severe ED usually need medical treatment, and a supplement that supplies raw materials for nitric oxide depends on blood vessels that can still respond.

Can I take it with Viagra, Cialis or heart medicine?

Not without your doctor. L-arginine, citrulline and beet nitrates raise nitric oxide, so combining them with sildenafil, tadalafil, nitrates such as nitroglycerin or isosorbide, or blood pressure medicine may drop your blood pressure too far. Ginkgo and dong quai can add to the effect of blood thinners, and niacin interacts with some statins.

What about the flushing?

If your face feels warm or red after a scoop, that is almost certainly the niacin. It usually fades as your body adjusts. Tell your doctor if it bothers you, and stop and get advice if you feel dizzy or faint, which points to blood pressure rather than niacin.

What if it does not work?

You have 60 days, and the FAQ says the refund applies even if you used every scoop. Call on a weekday or email support, then ship the jars to Adem Naturals in Tallmadge, Ohio at your own cost, or refuse the package on delivery. Do not leave it to the last weekend.

Do you get paid if I buy?

Yes, we may earn a commission if you order through our buttons. It does not change the price or what we write, and the buttons go to the official store, which is the only place the guarantee applies.
