Nitric Boost at a Glance
Nitric Boost is a powder for erectile dysfunction sold through ClickBank. One scoop a day contains beetroot, L-arginine, L-citrulline, niacin, horny goat weed, ginkgo, dong quai and D-aspartic acid, but the amounts are hidden in a proprietary blend. Arginine and citrulline helped mild erectile dysfunction in small trials at gram doses; whether one scoop supplies that much is unknown, and the powder itself is untested.
- Price: $49 to $69 per jar, depending on the package

What Nitric Boost is
Nitric Boost is a powder sold at getnitricboost.com, with ClickBank as the retailer. The jar is labelled Nitric Boost Ultra and holds 30 servings. It is marketed to men for firmer erections, on the idea that it helps the body make more nitric oxide, the molecule that lets the blood vessels in the penis relax so that blood can flow in. The directions are one scoop a day in water, a smoothie or tea. The site does not name the company behind it; orders ship from, and returns go to, a warehouse in Tallmadge, Ohio, that handles many products sold through ClickBank.
What is in it
The sales page names eight ingredients:
- Beetroot powder, a source of nitrate, which the body can turn into nitric oxide
- L-arginine, the amino acid the body makes nitric oxide from
- L-citrulline DL-malate, which the body converts into arginine
- Niacin (vitamin B3)
- Horny goat weed (epimedium), whose compound icariin weakly blocks the enzyme PDE5 in lab tests
- Ginkgo biloba powder
- Dong quai, a Chinese herb traditionally used for women’s health
- D-aspartic acid, an amino acid sold as a testosterone booster
No amounts are given. The FAQ calls the formula a “proprietary blend”, we could not find a Supplement Facts panel on the site or in the product images it gives affiliates, and the scoop size is not stated. That matters more here than for most products, because the ingredients with evidence only helped at doses of a gram or more.
What the evidence shows
- L-arginine: a 2019 meta-analysis of 10 randomized trials with 540 men found that 1,500 to 5,000 mg a day improved mild to moderate erectile dysfunction compared with placebo or no treatment. Side effects were more common with arginine (8.3% against 2.3%), though none was severe. In the trial the seller cites, 6 g a day for three months improved erection scores in men whose ED was caused by poor blood flow, but only 24% reached scores in the normal range, mostly men whose ED was mild to begin with.
- L-citrulline: in a small single-blind study of 24 men with mild ED, 1.5 g a day for a month brought erection hardness up to normal in 50% of them, against 8.3% while taking placebo.
- Niacin: in a 12-week trial of 160 men with both ED and high blood fats, up to 1,500 mg a day helped men with moderate or severe ED but not those with mild ED. That is a drug-sized dose, used to lower cholesterol; men need about 16 mg a day from food.
- Horny goat weed: its compound icariin improved erections in animal studies, but a 2026 review says the benefit still has to be confirmed in good human trials. See our epimedium page.
- Beetroot: its nitrate lowers blood pressure slightly and helps endurance, mostly in studies of beetroot juice. We found no trial of beetroot for erections; see our beetroot powder page.
- Ginkgo: in a two-month trial in 37 people with sexual problems caused by antidepressants, ginkgo did no better than placebo.
- Dong quai: we found no trials in men or for erections.
- D-aspartic acid: a 2017 review found that it raised testosterone in animals but gave inconsistent results in the four human studies, and a 2023 review of 27 “testosterone boosters” found that most do not raise testosterone. Our low testosterone guide explains how it is tested.
No study has tested Nitric Boost itself.
What the sales page claims
The sales page leads with a “Breaking” item: that ED is caused not by poor blood flow but by a shortage of cGMP, which it calls the “manhood molecule”, and that the medical community has had this wrong for decades. That is not a new finding, and it does not replace the blood-flow explanation. cGMP is the signal inside the penis that relaxes its blood vessels so that blood can flow in; ED medicines such as sildenafil (Viagra), approved in 1998, work by slowing its breakdown, and one of the seller’s own references describes this pathway. Narrowed or damaged blood vessels remain a leading cause of ED, which is why ED can be an early warning sign of heart disease.
- It says, without a source, that 47% of men find Viagra less effective over time.
- A strip of logos from Johns Hopkins, PubMed, the NIH and the New England Journal of Medicine sits under the header with no explanation. The page’s four references are listed on PubMed, but none of them is a study of Nitric Boost.
- The FAQ says the blend goes to work “immediately”, while the same FAQ recommends taking it for three to six months.
- The customer stories are labelled “Verified Purchase”, but the disclaimer says some names on the site have been changed and that “Jack Jordan” is a fictionalized character and a pen name.
Who should not take it
- After a heart attack: in the VINTAGE MI trial, 6 of the people given L-arginine after a heart attack (8.6%) died within six months, against none on placebo, and enrolment was stopped. The researchers concluded that L-arginine should not be recommended after a heart attack.
- Blood pressure, ED and angina medicines: L-arginine lowered systolic blood pressure by about 5 mmHg in a meta-analysis of 11 trials, and beetroot nitrate lowers it slightly too. ED medicines and nitrate medicines for angina, such as nitroglycerin, also lower blood pressure. If you take any of these, ask your doctor before adding Nitric Boost.
- Blood thinners: ginkgo and dong quai may raise bleeding risk. In one case report, a woman taking warfarin had her clotting test (INR) more than double after four weeks of dong quai. See our dong quai and ginkgo pages.
- If you have ED: see a doctor before trying supplements. ED can be the first sign of heart disease, diabetes or low testosterone, and proven treatments exist. Our erectile dysfunction guide explains the causes and treatments.
Price and refund
One jar (30 servings) costs $69 plus shipping. Three jars cost $177 ($59 each) and six cost $294 ($49 each), both with free US shipping and two bonus e-books; the page compares these with a crossed-out price of $199 a jar. It is a one-time payment, not a subscription, although the seller’s affiliate page also pays commission on “backend” sales, so you may be offered more products after checkout; you do not have to buy them. The 60-day guarantee covers used jars: contact support by email or phone, then send the jars back to the warehouse in Tallmadge, Ohio, at your own cost, or refuse the package when it arrives. Our Nitric Boost buying guide covers where it is sold and international shipping.
Realistic expectations
If your ED is mild, arginine or citrulline at the doses used in trials may help a little, but neither has the strong evidence behind prescription ED medicines, and Nitric Boost does not say how much of either it contains. If your ED is moderate or severe, or has come on recently, the most useful step is a check-up: the cause may be treatable, and it may matter for your heart.
🧪 Key Ingredients
What is in the formula, with a short note on each ingredient:
🌿 Beetroot Powder
Beetroot powder is a dried, ground form of the beet (Beta vulgaris), used mainly as a source of dietary nitrate, although nitrate levels vary widely between products. It is used to raise nitric oxide levels, with modest evidence, mostly from beetroot juice, for lower blood pressure and better endurance.
🌿 Dong Quai
Dong Quai is an herb native to East Asia, traditionally used in Chinese medicine to support women's health and blood circulation. Known scientifically as Angelica sinensis, it is promoted for hormonal balance, but human trials have not shown clear benefits.
🌿 Epimedium
Epimedium, widely known as horny goat weed, is an herb used for centuries in traditional Chinese medicine as a tonic, aphrodisiac and remedy for joint complaints. Its main active compound, icariin, affects blood-vessel and hormone pathways in lab and animal studies, but human evidence is limited.
🌿 Ginkgo Biloba
Ginkgo biloba is one of the world's oldest living tree species, and its leaf extract is widely taken in the hope of supporting memory and brain function. It is mainly used as a dietary supplement for circulation and brain health, although a large trial found it did not prevent dementia in older adults.
🌿 L-Arginine
Improved mild to moderate ED in small trials at 1,500 to 5,000 mg a day; not recommended after a heart attack.
🌿 L-Citrulline DL-Malate
Converted into arginine; 1.5 g a day helped mild ED in one small study.
🌿 Niacin (Vitamin B3)
Helped moderate to severe ED in men with high blood fats at up to 1,500 mg, a drug-sized dose.
🌿 Horny Goat Weed
Its compound icariin helped erections in animal studies; no good human trials.
🌿 D-Aspartic Acid
Sold as a testosterone booster; human studies are few and inconsistent.
*Always consult with your physician before starting any new supplement.

Frequently Asked Questions
Nitric Boost, labelled Nitric Boost Ultra, is a powder sold to men for firmer erections at getnitricboost.com, with ClickBank as the retailer. One scoop a day is mixed into water, a smoothie or tea, and a jar holds 30 servings.
The sales page lists beetroot powder, L-arginine, L-citrulline DL-malate, niacin, horny goat weed, ginkgo biloba, dong quai and D-aspartic acid. The amounts are not given: the formula is a proprietary blend.
The powder has never been tested. L-arginine at 1,500 to 5,000 mg a day improved mild to moderate erectile dysfunction in a meta-analysis of 10 small trials, and L-citrulline at 1.5 g helped in one small study, but Nitric Boost does not say how much of either it contains. The other ingredients have little or no human evidence for erections.
L-arginine should not be taken after a heart attack: in one trial, 6 of the people given it after a heart attack died, against none on placebo. L-arginine and beetroot can lower blood pressure, and ginkgo and dong quai may raise bleeding risk. If you have a heart condition or take any regular medicine, ask your doctor first.
Ask your doctor first. L-arginine lowered blood pressure by about 5 mmHg in trials, and beetroot nitrate lowers it slightly; ED medicines, blood pressure medicines and nitrates for angina lower it too.
The FAQ says it works immediately but also recommends taking it for three to six months. The arginine and citrulline trials lasted one to three months.
The site does not name a company. Orders ship from, and returns go to, a warehouse in Tallmadge, Ohio, that handles many products sold through ClickBank, and ClickBank is the retailer.
It is a real product sold through ClickBank with a 60-day refund. But its amounts are hidden in a proprietary blend, it has never been tested, and the sales page claims that the medical community has had erectile dysfunction wrong for decades, which the research does not support.
One jar costs $69 plus shipping, three cost $177 and six cost $294, both with free US shipping and two bonus e-books. It is a one-time payment, not a subscription.
You have 60 days, and the seller says it applies even to used jars. Contact support by email or phone, then send the jars back to the warehouse in Tallmadge, Ohio, at your own cost, or refuse the package on delivery. ClickBank’s order support at clkbank.com can also help.

See Why Everyone's Choosing This →How we scored Nitric Boost
Five weighted criteria — see our full methodology.
Whether the label discloses how much of each ingredient it contains, rather than hiding amounts inside a proprietary blend.
Whether the finished product has been tested in a published trial, or the claims rest on research into individual ingredients.
Monthly cost on the three-month package, the shortest course most vendors recommend (the single price for one-off digital products), compared against the rest of the category.
Length of the refund window measured against the trial period the vendor itself recommends.
How the product is sold: sales channel, checkout upsells, subscription defaults and how clearly the offer is presented.
Transparency is low: the sales page names eight ingredients but hides every amount in a proprietary blend, we could not find a Supplement Facts panel on the site or in the product images it gives affiliates, and the site does not name the company behind the product. Evidence is weak but not absent: L-arginine improved mild to moderate erectile dysfunction in a meta-analysis of 10 small trials at 1,500 to 5,000 mg a day, and L-citrulline helped in one small study at 1.5 g, but there is no way to tell whether one scoop supplies those amounts, the other six ingredients have little or no human evidence for erections, and the powder itself has never been tested. Buying practices score low: the sales page says the medical community has had erectile dysfunction wrong for decades, quotes an unsourced statistic about Viagra, shows logos of Johns Hopkins, PubMed, the NIH and the New England Journal of Medicine without explaining them, and its disclaimer says a name used on the site is a fictionalized character. In its favour, it is a one-time payment, a single jar can be bought, and the refund covers used jars.
Final Verdict
Nitric Boost is built on a real idea: L-arginine and L-citrulline feed the nitric oxide pathway behind erections, and both helped mild erectile dysfunction in small trials at gram doses. But every amount is hidden in a proprietary blend, so there is no way to tell whether one scoop comes close to those doses, and the other six ingredients have little or no evidence for erections. The powder itself has never been tested, and the sales page’s “manhood molecule” is the same pathway that ED medicines have targeted since 1998.
Safety matters more than usual here. L-arginine should not be taken after a heart attack, and if you take blood pressure medicine, a nitrate for angina, an ED medicine or a blood thinner, ask your doctor first. Above all, erectile dysfunction can be an early warning sign of heart disease or diabetes, so a check-up is the better first step. If you still want to try a nitric oxide supplement, choose one that states its arginine or citrulline dose, so you can match what the trials used.
