Quick verdict
- What it is: a once-daily nitric oxide drink powder for men, built on beetroot, L-citrulline and L-arginine plus five extras.
- Best part: it covers both nitric oxide pathways with ingredients that have real human research behind them.
- Biggest question: whether each scoop delivers research-level doses, which you can only judge from the label.
- Value: $49–$69 per jar (seller pricing), more than single-ingredient alternatives.
- Our score: 3.4 / 5. A reasonable all-in-one choice for healthy men who value convenience, not a must-have.
How we reviewed Nitric Boost Ultra
This is a research-based review. We examined the seller's published ingredient list and label, the order page's prices and guarantee, and the published human studies on each ingredient. We also compared the product with the cheaper ways men commonly get the same nutrients. We did not run a clinical test, and we did not receive a free product or payment from the seller to write this review; we earn a commission only if you buy through our links.
Our scoring weighs five things: the strength of the evidence for the ingredients, the transparency of the label, safety, value for money, and how fair the seller's terms are. You can read the full method in our editorial policy.
What Nitric Boost Ultra is
Nitric Boost Ultra is a flavored dietary supplement powder. One scoop mixed with water once a day is the seller's recommended serving, and one jar lasts about a month. The marketing speaks to men who want better blood flow, stamina, energy and confidence, especially as they get older. The seller's own page often calls the product simply "Nitric Boost", and independent reports name Adem Naturals in Ohio as the company behind it, with ClickBank as the retailer that handles payment.
The idea behind it is well grounded. Nitric oxide (NO) relaxes the muscle around blood vessels, and the body's ability to make it tends to decline with age, inactivity and poor diet. Feeding the body the raw materials for NO is a sensible, food-based approach. The question with any product like this is not whether the idea is sound, but whether the specific formula delivers enough of the right things.
The formula, ingredient by ingredient
The table below lists each ingredient, its main role, and our rating of the human evidence for that ingredient alone. Exact per-scoop amounts are on the Supplement Facts label.
| Ingredient | Main role | Human evidence | Amounts used in studies |
|---|---|---|---|
| Beet root powder | Dietary nitrate → nitric oxide | Good | About 300–500 mg nitrate (often from 500 ml juice or concentrated shots) |
| L-Citrulline DL-Malate | Raises arginine, supports NO | Good | 3–6 g citrulline; 6–8 g citrulline malate |
| L-Arginine | Direct NO building block | Moderate | 3–6 g per day |
| Niacin | Vitamin B3; skin vessel dilation | Moderate | Adult need 16 mg; flushing often from 30 mg+ |
| Ginkgo biloba | Circulation, antioxidant | Limited / mixed | 120–240 mg standardized extract |
| Horny goat weed | Traditional vitality herb | Limited (mostly lab/animal) | No established human dose |
| D-Aspartic acid | Hormone signaling | Limited / mixed | About 3 g per day |
| Dong quai | Traditional circulation herb | Limited | No established dose for this use |
Two things stand out. First, the formula is built on the right foundation: beetroot nitrate and citrulline are the two best-supported nitric oxide nutrients in the research, and combining them is logical because they use different pathways. Second, five of the eight ingredients have only limited evidence for this purpose. They are not harmful at sensible doses, but they mostly add marketing appeal rather than proven benefit. Dong quai in particular is an unusual choice in a men's product, as its traditional use is mainly in women's health.
For a deeper look at every ingredient, including the studies behind our ratings, see the Nitric Boost Ultra ingredients guide.
The dose question
This is the most important part of any supplement review, and it is where many multi-ingredient products fall short. A study showing that 6 grams of citrulline improves blood flow tells you very little about a product that contains 600 milligrams.
Look at the label with this simple test. Add up the citrulline and arginine amounts. If together they reach several grams per scoop, the formula is in the range used in research. If the scoop is small and the amino acids sit below about 1 to 2 grams combined, expect a gentle effect at best. For beetroot, the useful number is nitrate content, which labels rarely state; plain beet powder contains far less nitrate per gram than the concentrated juices used in most studies.
Powders have an advantage over capsules here. Two capsules can only hold about 1 to 1.6 grams in total, while a scoop of powder can hold several grams. So the format gives Nitric Boost Ultra room to reach meaningful amounts; the label tells you whether it uses that room.
Pros and cons
Pros
- Covers both nitric oxide pathways in one product
- Core ingredients have good human research
- Powder format allows larger doses than capsules
- Stimulant-free, so suitable for evening use
- 60-day money-back guarantee (seller-stated)
- Free US shipping on 3- and 6-jar orders
Cons
- No clinical trial on the finished product
- Five of eight ingredients have weak evidence
- Pricier than single-ingredient citrulline or beet powders
- Niacin flush may bother some users
- Several interactions to check (blood pressure, PDE5, blood thinners)
- Confusing copycat sites with conflicting prices and guarantees
What customers say
The seller's page features a few glowing five-star testimonials about energy, confidence and relationship satisfaction. These are hand-picked, unverified and impossible for us to check, so we do not reproduce them. We also could not trace the large customer numbers that appear in some promotional articles to any independent source.
Independent feedback is still thin, which is common for products sold only online through one checkout. When you read user reviews elsewhere, look for specific, balanced details such as how long someone used it, what changed and what did not, and whether they had side effects. Reviews that only repeat marketing phrases are usually ads.
If you want a balanced view of the red flags, our Nitric Boost Ultra scam or legit check goes through them one by one.
Safety
For healthy adults, the ingredients are generally well tolerated. Expect the possibility of a niacin flush, mild stomach upset in the first days, occasional headaches, and pink urine from beetroot. The serious concerns are interactions: the formula may add to the effect of blood pressure medicines, should not be combined with nitrate heart medications or PDE5 drugs without medical advice, and the ginkgo and dong quai content means anyone on blood thinners should check with a doctor first. Our side effects guide covers this in detail.
Price and value
According to the seller, one jar costs $69 plus shipping, three jars cost $177 ($59 each), and six jars cost $294 ($49 each), with free US shipping and two bonus e-guides on the bigger packages.
| Option | Approx. cost per day | What you get |
|---|---|---|
| Nitric Boost Ultra, 1 jar | About $2.63 (with shipping) | 8-ingredient formula, guarantee |
| Nitric Boost Ultra, 6 jars | About $1.63 | Same, lowest per-day price |
| Plain L-citrulline powder | About $0.50–$1.00 | One ingredient, clear dose |
| Concentrated beetroot shots | About $1.50–$3.00 | Measured nitrate, one pathway |
On pure cost per gram of active nutrient, single ingredients win. You are paying for convenience, the extra herbs and the guarantee. That trade is reasonable if you value an all-in-one drink and will actually use it daily; it is poor value if you are happy measuring two cheap powders yourself. See our price and coupon guide for ways to pay less.
Alternatives worth considering
- L-citrulline powder alone: the cheapest way to support the amino acid pathway, with an easy-to-check dose.
- Beetroot juice or nitrate-standardized beet shots: best for athletes who want a measured nitrate dose before training.
- Food first: leafy greens such as arugula, spinach and lettuce, plus beets, are naturally rich in nitrate. Watermelon contains citrulline.
- Lifestyle: regular aerobic exercise, not smoking, good sleep and managing weight all support healthy blood vessel function more than any supplement.
Who it is for, and who should skip it
A good fit if you
- are a generally healthy adult man
- want one simple daily drink rather than several products
- are interested in exercise stamina and everyday energy
- are willing to give it 4 to 8 weeks
Skip it or ask your doctor if you
- take blood pressure, nitrate, PDE5 or blood-thinning drugs
- have heart, kidney or liver disease or low blood pressure
- want a treatment for erectile dysfunction (see a doctor)
- are on a tight budget and comfortable with single ingredients
Editorial scorecard and final verdict
This is our editorial opinion of the product's design and terms, not a customer rating.
Nitric Boost Ultra gets the fundamentals right. Beetroot nitrate and citrulline are exactly the ingredients a biologist would choose to support nitric oxide, and a powder can deliver them in useful amounts. It loses points for leaning on several weakly supported herbs, for a price well above simpler options, and for the marketing noise around it. If you are a healthy man who wants an easy, stimulant-free daily drink and you will use it consistently, it is a reasonable choice, especially with a 60-day guarantee as a safety net. If you take heart or blood pressure medication, speak to your doctor first.

Is Nitric Boost Ultra worth it?
It can be for a healthy man who wants a convenient all-in-one drink and will use it daily. If you mainly want citrulline at the lowest cost, a single-ingredient powder is better value.
Did you test it yourself?
This review is research-based. We analyzed the formula, label, evidence and terms rather than reporting a personal trial.
How long should I try it before judging?
Give it at least four weeks of daily use. Many people judge it at eight weeks, well within the 60-day guarantee window.
Is it safe with blood pressure medicine?
Ask your doctor first. Nitric oxide support may add to the effect of blood pressure drugs.
