Nitric Boost Ultra Review: What’s Inside, and Does It Work?
Nitric Boost Ultra is a nitric oxide powder marketed for men’s vitality, blood flow and stamina. I went through the formula ingredient by ingredient, compared it with the published research, and pulled together what you should know about price, safety and the refund policy before ordering.
How this review was made: based on the manufacturer’s published information and peer-reviewed studies. I have not personally tested this product. Read about my review process.
Key takeaways
- Best-supported ingredients: L-citrulline and beet root nitrates
- Weakest evidence: ginkgo, D-aspartic acid and dong quai
- Price: $49 to $69 per jar, depending on the bundle
- Refund policy: 60-day money-back guarantee, per the seller
- Talk to a doctor first if you take ED drugs, nitrates or blood thinners
How Nitric Boost Ultra is supposed to work
Erections depend on healthy blood flow. Nitric oxide (NO) signals the smooth muscle in blood vessel walls to relax, which lets more blood in. Inside the muscle cells, that signal is carried by a molecule called cGMP, and an enzyme called PDE5 gradually breaks it down. Prescription ED medications work by blocking PDE5.
Nitric Boost Ultra tries to support this chain with food-derived ingredients instead of drugs. The idea is sound in principle. The open question is whether one scoop contains enough of each ingredient to make a noticeable difference, which is why the ingredient evidence below matters more than the marketing.
Raise NO supply
Beet root nitrates, L-arginine and L-citrulline give the body raw material to produce nitric oxide.
Protect the vessels
Niacin and antioxidant botanicals such as ginkgo are included to support the lining of blood vessels.
Support the signal
Epimedium contains icariin, which mildly blocks PDE5 in lab studies. D-aspartic acid is added for hormone support.
What the research says about each ingredient
Ratings reflect the strength of human evidence for blood flow or sexual function, not this specific product. Click “Study” to read the source.
L-Citrulline DL-Malate
ModerateConverted to L-arginine in the kidneys, raising arginine levels more reliably than arginine itself. A small Italian trial found it improved erection hardness in men with mild ED compared with placebo.
Beet Root Powder
ModerateA rich source of dietary nitrate. Meta-analyses show nitrate and beetroot juice modestly lower blood pressure, a sign of better vessel relaxation. Direct evidence for erectile function is still limited.
L-Arginine
LimitedThe direct building block for nitric oxide. A 2019 meta-analysis found arginine improved mild-to-moderate ED versus placebo, mostly at doses of 1.5 to 5 g per day. Much of an oral dose is broken down before reaching circulation.
Epimedium (Horny Goat Weed)
LimitedIts active compound, icariin, inhibits PDE5 in laboratory studies, but far more weakly than prescription drugs. Good-quality human trials are scarce.
Niacin (Vitamin B3)
LimitedSupports blood vessel function and blood lipids. A Hong Kong trial found niacin improved erectile function in men with moderate-to-severe ED and high cholesterol, but not in milder cases.
Ginkgo Biloba
Weak / mixedAn antioxidant studied for circulation and memory. In a placebo-controlled trial on antidepressant-related sexual problems, ginkgo performed no better than placebo.
D-Aspartic Acid
Weak / mixedInvolved in hormone signaling. Results are inconsistent: in resistance-trained men, 3 g per day had no effect on testosterone and 6 g per day lowered it.
Dong Quai
Weak / mixedA traditional Chinese herb used mostly in women’s health. There is little to no human research on male sexual function, and it has a documented interaction with the blood thinner warfarin.
How much does Nitric Boost Ultra cost?
Bundles bring the price per jar down. These are the prices listed at the time of writing. Offers change often, so confirm the final total at checkout.
One-time payment, no subscription, according to the seller.
How to take it and what to expect
The manufacturer recommends one scoop per day, mixed into water, a smoothie or tea. Taking it at the same time each day makes it easier to stay consistent.
Timeline: nitrate-rich ingredients like beet root can affect blood vessels within a few hours, but most studies on citrulline, arginine and niacin measure results after 4 to 12 weeks of daily use. If you try it, give it at least a month before judging, and keep the refund deadline in mind.
Get the basics right too. Supplements work best on top of the habits with the strongest evidence for blood flow: regular exercise, a healthy weight, not smoking, limiting alcohol and good sleep.
Possible side effects and who should talk to a doctor first
Most of these ingredients are well tolerated by healthy adults in normal food-level amounts. Possible side effects include stomach upset, headache, skin flushing (from niacin) and harmless pink or red urine (from beet root).
Erection problems can also be an early sign of heart disease or diabetes, so it’s worth seeing a doctor even if you plan to try a supplement.

Alternatives worth considering
Nitric Boost Ultra isn’t the only way to support healthy blood flow. Depending on your goals and budget, these may be worth a look.
Standalone L-citrulline
If citrulline is the ingredient with the most interest for you, a plain citrulline powder lets you control the exact dose, often for less money.
Nitrate-rich foods
Beets, arugula, spinach and celery are natural sources of dietary nitrate. Beetroot juice is the form used in most blood pressure studies.
Lifestyle changes
Exercise, weight loss, quitting smoking and cutting back on alcohol have some of the strongest evidence for improving erectile function.
Talk to your doctor
Prescription treatments are well studied and effective for many men. A doctor can also check for underlying causes like heart disease or diabetes.
Bonuses and refund policy
Multi-jar orders currently include two digital guides, according to the seller.
The Nitric Boost Blueprint
A digital guide on diet and lifestyle habits that support healthy nitric oxide levels.
Marathon Man Stamina
A digital guide covering breathing, pelvic floor exercises and mental techniques for endurance.
60-day money-back guarantee
The seller offers a full refund within 60 days of purchase if you’re not satisfied, even on opened containers. Save your order confirmation and contact support before the deadline. Since most studies measure results after 4 to 12 weeks, start using it right away so you have time to judge before the window closes.
Frequently asked questions
Does Nitric Boost Ultra actually work?
Some of its ingredients, mainly L-citrulline and beet root nitrates, have reasonable evidence for supporting blood flow. The product itself hasn’t been tested in a published clinical trial, and the doses per scoop aren’t disclosed on the sales page, so individual results will vary.
What are the side effects of Nitric Boost Ultra?
Most people tolerate these ingredients well. Possible side effects include stomach upset, headache, skin flushing from niacin and red-tinted urine from beet root. People on ED drugs, nitrates, blood thinners or blood pressure medication should talk to a doctor first.
How long does it take to work?
Some nitrate effects appear within hours, but most studies on the main ingredients measure results after 4 to 12 weeks of daily use. Give it at least a month before judging.
Can I take it with Viagra or Cialis?
Don’t combine them without your doctor’s approval. Both can lower blood pressure, and stacking them may cause dizziness or fainting.
Is Nitric Boost Ultra sold on Amazon?
The manufacturer says it’s sold through its official website, which also handles the money-back guarantee. Third-party listings may not be authorized, and purchases outside the official site may not qualify for a refund.
How much does Nitric Boost Ultra cost?
At the time of writing, one jar costs $69, three jars cost $177 ($59 each) and six jars cost $294 ($49 each). Prices change, so confirm the total on the official checkout page.
What is the refund policy?
The seller offers a 60-day money-back guarantee, including on opened containers. Keep your order confirmation and contact customer support before the 60 days are up.
Is it a subscription?
According to the seller, it’s a one-time payment with no automatic rebilling.
Is Nitric Boost Ultra safe for women?
It’s marketed to men, and the formula hasn’t been studied in women. Anyone pregnant or breastfeeding should avoid it.
Is Nitric Boost Ultra worth trying?
It’s a reasonable formula built around nitric oxide, with two well-supported ingredients and several weaker ones. If you’re healthy, cleared by your doctor and comfortable with undisclosed doses, the money-back guarantee makes it a low-risk experiment. If you want precise dosing or proven results, a single-ingredient supplement or a conversation with your doctor is the better first step.
