What is Nitric Boost Ultra, and what does the sales page claim?

Nitric Boost Ultra is a once-daily drink powder sold online for men’s sexual performance, with 30 scoops in each jar. The jar says Nitric Boost Ultra, while the sales and checkout pages mostly say Nitric Boost[1][2]. BuyGoods is named as the retailer at the bottom of the sales page[1]. No study of the product itself is cited anywhere we looked.

The Nitric Boost sales page headline and video. Screenshot of trynitricboost.me, checked October 20, 2026.

The page opens with a video under the headline “I Thought My Sex Life Was Over… Until I Found This Powerful Natural Fix”[1]. It is a marketing line with nothing behind it in the research. Lower on the second sales page, the seller says the root problem is a shortage of cGMP, which it nicknames the “manhood molecule,” and that “the solution lies in blocking PDE5”[2]. No researchers or study are named for that story.

A few product facts are worth knowing before price:

  • The directions are 1 scoop a day with a glass of water, or mixed into a smoothie or tea[1]. The weight of a scoop is not given anywhere[1][2].
  • The seller describes it as free of soy, dairy and stimulants, vegetarian and non-GMO[1].
  • The page says it is made in the USA in a GMP facility with third-party inspections, but it names neither the plant nor the inspector[1].
  • The sales page footer says the presenter, “Jack Jordan,” is “a fictionalized character and is a pen name”[2].

The shipping and terms pages also carry text copied from other products, such as the name “ProvaDent” on the shipping page[4]. It does not change what is in the jar, but it tells you how carefully the pages were put together.

How is Nitric Boost Ultra supposed to work?

The seller says the powder raises nitric oxide and protects cGMP, the chemical signal that relaxes blood vessels in the penis. That pathway is real: prescription PDE5 inhibitors work on it and improve blood flow[6]. What is missing is any proof that this powder, at its unknown doses, moves that pathway in people[2].

The sales copy draws a chain. Beet nitrate and the amino acids L-arginine and L-citrulline are raw materials the body can turn into nitric oxide. Nitric oxide raises cGMP. Horny goat weed is said to “help protect cGMP” by acting a little like a PDE5 blocker[2]. Each step has some lab support. The trouble is the size of the effect.

Prescription PDE5 inhibitors are tested drugs with known doses. In lab work, icariin from horny goat weed is a weak PDE5 blocker, and it is broken down heavily in the gut, so lab results do not carry over to a person[17]. The nitric oxide raw materials worked in trials only at gram-level doses, as the ingredient section shows[7][9][13].

The NIH also frames erection problems more broadly than the sales page does. NIDDK lists heart and blood vessel disease, high blood pressure, diabetes, low testosterone, nerve damage and many common medicines as causes[5]. A powder cannot sort out which of those applies to you.

What ingredients are in Nitric Boost Ultra?

The seller names eight ingredients and gives no amount for any of them. The list appears only on the ClickBank sales page; the BuyGoods page we link to shows none[1][2]. The seller calls the formula a proprietary blend, and the flavoring and sweetener are not named either[2].

That matters because the three ingredients with the most human data for blood flow work at gram doses. We cannot tell whether one scoop gets close, since even its weight is hidden[1][2].

Nitric Boost Ultra ingredients next to the research
Ingredient Best human evidence Dose in studies Grade
L-citrulline One small trial in 24 men with mild erection problems[7] 1.5 g a day Limited
L-arginine Beat placebo in a network analysis of 15 trials[8] Gram doses; 4 to 24 g for blood pressure[9] Limited
Beet root Small blood pressure drop; no erection trial[12][13] 70 to 250 ml of juice a day None for erections
Niacin One trial in men with high cholesterol[14] Up to 1,500 mg a day Weak
Horny goat weed Animal and lab data only[17] Not set for men Very weak
Ginkgo biloba Studied for memory and eyes, not erections[18] 120 to 240 mg a day None for erections
Dong quai No male sexual-health trial[19] Varies None
D-aspartic acid Testosterone trials, mostly null[22][23][24] 3 to 6 g a day Weak

L-citrulline

The best direct trial is small. In 2011, Italian researchers gave 24 men with mild erection problems a placebo for a month and then 1.5 g of L-citrulline a day for a month. Erection hardness reached the normal score in 50% of men on citrulline, against 8.3% on placebo[7]. The trial was single-blind, and the authors said citrulline was less effective than PDE5 inhibitors[7]. Nitric Boost Ultra uses a citrulline malate form, and how much citrulline that leaves per scoop is unknown[2].

L-arginine

A network analysis of 15 randomized trials of supplements for erection problems found that, among single ingredients, only L-arginine beat placebo[8]. Blood pressure trials used 4 to 24 g a day and found a small drop[9]. Those are large amounts, often several grams at a time. Arginine also carries a warning: the VINTAGE MI trial in heart attack survivors was stopped early because more people died in the arginine group[10].

Beet root powder

Beets supply nitrate, which the body turns into nitric oxide. A pooled analysis of 16 trials with 254 adults found systolic blood pressure fell by 4.4 mmHg, and the effect grew with the nitrate dose[12]. In people with high blood pressure, 70 to 250 ml of juice a day lowered systolic pressure by about 4.95 mmHg[13]. No human trial of beet for erections turned up. Powders often hold far less nitrate than juice.

Niacin

One trial gave 160 men with erection problems and high cholesterol up to 1,500 mg of niacin a day for 12 weeks. Overall, niacin did no better than placebo, though men with moderate or severe problems improved[14]. That dose is more than 40 times the adult upper limit of 35 mg a day from supplements[15]. Above about 30 to 50 mg, niacin often causes flushing, itching and warmth[16].

Horny goat weed

Horny goat weed, also called epimedium, contains icariin. Rat studies show better erections, but a 2022 review said human proof is lacking[17]. We found no adequate human trial for erection quality.

Ginkgo biloba and dong quai

Ginkgo has been studied mostly for memory and eye health, and NCCIH says large trials found no drop in dementia rates with it[18]. Dong quai is a traditional women’s herb; the one trial in men tested hot flashes, not sexual function[19]. What both add is a bleeding question. NCCIH warns that ginkgo may raise bleeding risk with blood thinners, and a case report linked dong quai to a sharp rise in warfarin effect[18][20].

D-aspartic acid

D-aspartic acid is sold to support testosterone. A 2009 study of 23 men found testosterone rose after 12 days at 3.12 g a day[21]. Later trials in trained men found no change at 3 g, a drop at 6 g, and no change after three months at 6 g[22][23]. A 2023 review concluded that most testosterone boosters, this one included, do not raise testosterone[24].

Does Nitric Boost Ultra work for erection quality?

No trial has tested Nitric Boost Ultra, so nobody can say from the research whether it improves erection quality. Two of its ingredients, L-arginine and L-citrulline, have small positive trials at gram doses[7][8]. The other six have no human trial for erections. The doses in a scoop are hidden, so the trial results cannot be applied to it[2].

The label names the right family of ingredients for a nitric oxide pitch. It does not let you check whether there is enough of any of them. A jar of 30 scoops would need to hold at least 45 g of citrulline alone to match the 1.5 g daily dose in the 2011 trial, and the seller does not publish the jar’s fill weight[1][7].

Three more points shape what a buyer can expect:

  1. The strongest single ingredient, L-arginine, is also the one with the clearest heart warning[8][10].
  2. The citrulline trial showed a smaller effect than prescription PDE5 inhibitors, even at a known dose[7].
  3. Erection problems often come from blood vessel disease, diabetes or medicines, which need their own care[5].

The sales page itself notes that “results atypical and vary from person to person”[1]. Treat any change you notice as possible but unproven, and measure it against the refund date rather than the video.

What are Nitric Boost Ultra side effects, and who should skip it?

The seller lists no side effects, but several ingredients have known ones: flushing from niacin, lower blood pressure from arginine, citrulline and beet nitrate, and bleeding risk from ginkgo and dong quai. The size of each risk depends on the dose, which is not published[2][11][16][18][19].

Nitric Boost Ultra ingredients with a safety flag
Ingredient Possible problem Who should take care
L-arginine, L-citrulline, beet root Added blood pressure lowering[11][12] Men on nitrates such as nitroglycerin, PDE5 inhibitors or blood pressure drugs
L-arginine More deaths after heart attack in one trial; may trigger herpes[10][11] Anyone who has had a heart attack or gets cold sores
Niacin Flushing, itching; liver strain at high doses[15][16] People with liver disease, or on statins or diabetes medicine
Ginkgo biloba Bleeding risk, dizziness, headache[18] People on warfarin, aspirin or other blood thinners, or facing surgery
Dong quai Bleeding risk, sun sensitivity[19][20] People on blood thinners or with hormone-sensitive conditions
Beet root Red urine or stools; oxalate[12] People prone to kidney stones

The most serious mix is with nitrate heart drugs and PDE5 inhibitors. Both lower blood pressure through the same pathway that arginine, citrulline and beet nitrate feed, so the effects can stack[11]. If you already take a prescription erection drug, ask your doctor before you add this powder.

NIDDK advises talking with a health care professional before using dietary supplements for erection problems, and not ordering erection medicine online without one[6]. Since erection problems can come from heart and blood vessel disease, a check-up is worth doing first[5]. Seek care quickly for chest pain, fainting or an erection that lasts more than four hours.

Bars, price per jar: 1 jar $69; 3 jars $177 total, $59 a jar; 6 jars $294 total, $49 a jar. Takeaways: one jar costs $69 plus shipping, the lowest total; six jars cut the price to $49 a jar but the guarantee stays 60 days; returns are mailed to Ohio at the buyer cost. Talk to a doctor first if you take heart, blood pressure, blood thinning or erection medicine.

The seller describes the purchase as a one-time payment with no subscription[1]. The two bonuses are e-books whose dollar value is set by the seller, so we leave that value out. US orders arrive in 5 to 7 working days, per the shipping terms[4].

Nitric Boost Ultra cost per day by package
Package Total paid Servings Cost per day
1 jar $69 plus shipping 30 $2.30 before shipping
3 jars $177 90 $1.97
6 jars $294 180 $1.63

The math assumes 1 scoop a day and 30 scoops per jar, as the seller states[1]. A 6-jar order lasts six months, but the refund window stays at 60 days, so most of that order would arrive after you could judge the first jar.

To try it with the least money at risk:

  1. Check with your doctor or pharmacist first if you take any heart, blood pressure, blood thinning or erection medicine[6][11].
  2. Choose the smallest package you are willing to test. The 1-jar card costs more per jar but less in total[1].
  3. Write down the order date and set a reminder for day 50.
  4. Keep the receipt, the order email and the tracking number.
  5. Keep unopened jars sealed and in their box until you decide.
  6. Turn down any extra offers after checkout unless you planned for them.

Does Nitric Boost Ultra have a money-back guarantee?

Yes. The seller offers a 60-day money-back guarantee and its FAQ says you can return the containers “even if empty” for a full refund. You still pay to ship the jars back, or you can refuse the package on delivery[1][3]. The page does not say whether the 60 days start on the order date or the delivery date[3].

The Nitric Boost refund request form. Screenshot of trynitricboost.me/refunds, checked October 20, 2026.

The refund page is a short form. It asks for your name, email, phone number, preferred contact method, whether you want a return or a refund, and a reason, such as product issues, change of mind, unsatisfactory results or billing errors[3]. The steps it sets out:

  1. Fill in the form on the refund page, or email support@getnitricboost.com, or call 1 (814) 885 4823 on weekdays[3].
  2. Mail the jars at your own cost to Adem Naturals, 285 Northeast Ave, Tallmadge, OH 44278[3].
  3. Keep proof of postage and the tracking number until the refund lands.
  4. If the seller does not answer, contact the retailer that took your payment, BuyGoods or ClickBank[1][2].

The sales page says the guarantee is “no questions asked”[1]. When the dossier for this review was built, the second sales site’s refund page held a hidden line saying only unopened bottles qualify. Buyers do not see it, but get any refund promise confirmed in writing before you mail jars back.

Where can you buy Nitric Boost Ultra?

Buy it through the seller’s own sales pages, where BuyGoods or ClickBank processes payment and the 60-day guarantee applies. The seller’s affiliate rules bar sales on Amazon, eBay and other marketplaces, so a listing there is not an authorized seller[1][2]. A copy from a third party may lack the refund terms, and you cannot see how it was stored.

Searches for Nitric Boost Ultra capsules, gummies or pills turn up pages selling other formats. The seller’s pages sell only a powder in a jar[1][2]. If the product that arrives is a capsule, it is not the one reviewed here.

Orders ship from Ohio, and the tracking email follows within a few days[3][4].

What do Nitric Boost Ultra reviews and complaints show?

We found almost no independent customer record for Nitric Boost Ultra. A Better Business Bureau search for Nitric Boost returns other products and no profile for this one[25]. Trustpilot blocked our reader, so we did not check it. The BBB page for Adem Naturals, the returns company, also blocked us, so we did not read its rating.

The sales pages carry their own numbers, but they cannot be checked. One shows an “Average Customer Rating 4.9” and says 96% of customers order 6 jars; the other says 87% order 6 bottles[1][2]. The two figures do not agree with each other.

The testimonials on the pages are written by the seller, so we do not count them as customer data. The second sales page says some names and details have been changed and the presenter is a pen name[2]. If you buy, the most useful record you can keep is your own: the order date, what you noticed each week and when you asked for a refund.

What do nitric oxide supplements actually do?

Nitric oxide supplements supply raw materials, mainly nitrate, arginine and citrulline, that the body can turn into nitric oxide, a gas that relaxes blood vessels. In trials, they lowered blood pressure a little and helped exercise slightly at gram doses[9][12][13]. They do not contain nitric oxide itself.

The effects in trials are modest. Beet juice lowered systolic pressure by about 4 to 5 mmHg[12][13]. Arginine produced a small drop at 4 to 24 g a day[9]. For erections, only arginine and citrulline have trials, and both were small[7][8].

So a nitric oxide product is only as good as its doses. When those are hidden, as here, you are paying for the ingredient names. This is the same problem we flagged in our PrimeBiome review of a proprietary-blend formula.

Are there cheaper, better-tested options for erection problems?

Yes. NIDDK lists PDE5 inhibitors, changes to medicines that cause erection problems, quitting smoking, a healthy eating plan and more physical activity as the main steps. PDE5 drugs are prescription medicines with known doses that improve blood flow[6]. A doctor can also look for causes such as diabetes or high blood pressure[5].

A sensible order to work through:

  1. See a doctor for a check-up, since erection problems can point to heart and blood vessel disease[5].
  2. Ask whether any of your current medicines, such as some blood pressure drugs or antidepressants, could be part of the cause[5]. Do not stop a medicine on your own[6].
  3. Stop smoking, which is linked to blood vessel disease[6].
  4. Move more and follow a healthy eating plan[6].
  5. Ask about prescription treatment if the problem continues[6].
  6. Get prescription medicine only through a licensed prescriber, never from an unknown website[6].

Foods carry some of the same raw materials. Beets, spinach and other leafy greens hold nitrate, and the beet trials used juice, not powder[12][13]. For a wider look at how we judge supplement sellers, see how we check whether a supplement seller is legit and our Mitolyn review with refund terms explained.

Who is Nitric Boost Ultra best for?

Nitric Boost Ultra may suit a healthy man with no heart condition and no regular medicines who has already seen a doctor, accepts that the doses are hidden and will track the 60-day refund date. It is a poor fit for men on nitrates, PDE5 inhibitors, blood pressure drugs or blood thinners, and anyone who has had a heart attack[10][11][18][20].

If you try it, buy the package you can afford to lose, keep the extra jars sealed, and note any change each week. If nothing has changed by day 50, start the return[3]. If new erection problems come with chest pain, shortness of breath or diabetes symptoms, see a doctor before you buy anything[5].

Frequently asked questions

Where can I buy Nitric Boost Ultra?

Order through the seller's own sales pages, where BuyGoods or ClickBank takes payment and the 60-day guarantee applies. The seller does not allow sales on Amazon or eBay, so marketplace listings may carry other terms or another product.

Does Nitric Boost Ultra have a money-back guarantee?

Yes, 60 days. The FAQ says jars can come back even if empty for a full refund. You start it with the refund form, email or phone, then mail the jars to Ohio at your own cost and keep the tracking number.

What are the Nitric Boost Ultra side effects?

The seller lists none. Niacin can cause flushing, arginine, citrulline and beet nitrate can lower blood pressure, and ginkgo and dong quai can raise bleeding risk. Men on nitrates, erection drugs, blood pressure medicine or blood thinners should ask a doctor first.

How do you take Nitric Boost Ultra?

The seller says to take 1 scoop of the powder a day with a glass of water, or mixed into a smoothie or tea. Each jar holds 30 servings. The scoop weight and the amount of each ingredient are not published.

How long does Nitric Boost Ultra take to work, according to the seller?

The FAQ says the blend goes to work right away, but no study backs a time frame. The packages are sold as 30, 90 and 180 days of supply. Judge any change before day 50 so the refund window is still open.

Is Nitric Boost Ultra legit?

It is a real product sold through two known retailers, BuyGoods and ClickBank, with a written 60-day refund policy and a US returns address. The weak points are hidden doses, no product trial, a presenter who is a pen name and seller-written testimonials.
