What is NitriLean?

NitriLEAN is a dietary supplement for weight loss. This formula’s unique combination of ingredients can aid in the loss of stubborn fat. The supplement is intended to improve health and blood flow when used in conjunction with proper weight management.

According to the NitriLEAN website, the supplement may improve blood flow and metabolism while also supporting a healthy heart.

The supplement contains eight natural plant extracts that are claimed to be effective at promoting weight loss while remaining safe. It promotes heart health and a higher metabolism, which aids the body in losing excess fat, particularly in adults over the age of 30.

This is not a miracle weight-loss supplement that will make you lose weight overnight, and the results are not guaranteed. It merely enhances the body’s pre-existing functions in terms of supplements. Furthermore, this supplement is manufactured in accordance with FDA safety guidelines.

Many people nowadays talk about losing weight. Dieting is the most popular way to lose weight. However, people who are obese due to a faulty metabolism may not benefit from this. Individuals who are neither overweight nor obese may also struggle to lose abdominal fat.

Belly obesity can cause a number of comorbidities as well as cosmetic issues. Obesity is linked to a number of serious health issues; it does not occur in isolation.

It is impossible to monitor the nutrition of people who follow different diets based on their physical characteristics.

Low-carb, paleo, Mediterranean, vegan, Atkins, and other diets are difficult to maintain. They cause nutritional deficiency when done without authorization.

Losing weight is difficult until the underlying cause of obesity is addressed. There are now new treatments that are innovative, safe, and effective.

NitriLEAN, in particular, is a highly effective weight loss supplement. NitriLEAN can help you lose weight quickly by improving your metabolism and reducing belly fat.

This supplement is non-GMO and non-GMO due to its natural ingredients and clinically proven active ingredients. NitriLEAN can help people with stubborn abdominal fat lose weight while also improving their cardiovascular health.

Beet Root

Beetroot (Beta vulgaris) is a root vegetable also known as red beet, table beet, garden beet, or just beet.

Packed with essential nutrients, beetroots are a great source of fiber, folate (vitamin B9), manganese, potassium, iron, and vitamin C.

Beetroots and beetroot juice have been associated with numerous health benefits, including improved blood flow, lower blood pressure, and increased exercise performance.

Many of these benefits are due to their high content of inorganic nitrates.

Beetroots are delicious raw but more frequently cooked or pickled. Their leaves — known as beet greens — can also be eaten.

There are numerous types of beetroot, many of which are distinguished by their color — yellow, white, pink, or dark purple.


Citrulline is an amino acid that was first found in watermelon.

It is considered nonessential, meaning that your body can naturally produce some on its own.

However, you can increase your levels by eating foods containing citrulline or by taking dietary supplements, rather than relying on your body’s production alone.

These higher levels may produce beneficial effects on health and exercise performance, as discussed later in this article.

Citrulline has important roles in the body, but unlike some amino acids, it is not used to build proteins.

However, it plays a necessary part in the urea cycle, which rids your body of harmful compounds. Specifically, the urea cycle removes ammonia from the body. The final product of this cycle is urea, which your body gets rid of in urine.

Citrulline can also help widen your blood vessels and may play a role in muscle building.

Hawthorn Extract

Hawthorn berries are tiny fruits that grow on trees and shrubs belonging to the Crataegus genus.

The genus includes hundreds of species commonly found in Europe, North America, and Asia.

These nutrient-rich berries have a tart, tangy taste and mild sweetness. They range in color from yellow to dark red.

For hundreds of years, people have used hawthorn berry as an herbal remedy for digestive problems, heart issues, and high blood pressure. In fact, the berry has been a key part of traditional Chinese medicine since at least 659 A.D.

Green Tea Extract

Green tea is one of the most commonly consumed teas in the world.

Green tea extract is its concentrated form, with just one capsule containing the same amount of active ingredients as an average cup of green tea.

Like green tea, green tea extract is a great source of antioxidants. These have been credited with a range of health benefits — from promoting heart, liver, and brain health to improving your skin and even reducing the risk of cancer.

What’s more, many studies have looked at the ability of green tea extract to aid weight loss. In fact, many weight loss products list it as a key ingredient.

Garcinia Cambogia

Finding out what garcinia cambogia is and how it works can help people understand whether the weight loss claims are true and whether the supplement will work.

It is also important to realize that there are some risks and interactions to be aware of when using garcinia cambogia.

Garcinia cambogia contains an ingredient called hydroxycitric acid (HCA), which has been used to aid weight loss. The extract of HCA is available in powdered form or pill form and can be purchased online or in health stores.

Cayenne Pepper

Cayenne peppers, scientifically known as Capsicum annuum,belong to the Solanaceae or nightshade plant family, which also includes tomatoes, eggplant, and potatoes.

They’re a type of chili pepper and have a moderately hot, spicy flavor thanks to a compound called capsaicin.

Hot peppers like cayenne peppers may offer some health benefits, but research is limited on the potential health benefits related to cayenne pepper consumption specifically.

Note that capsaicin, the compound that gives cayenne peppers their signature spicy flavor, is linked to some health benefits when consumed in supplement form.

However, since the related research didn’t investigate cayenne pepper specifically, more studies are needed.

Nonetheless, adding cayenne peppers to your diet may benefit your health in a few ways.

Grape Seed

Grape seed extract (GSE) is a dietary supplement made by removing, drying, and pulverizing the bitter-tasting seeds of grapes.

Grape seeds are rich in antioxidants, including phenolic acids, anthocyanins, flavonoids, and oligomeric proanthocyanidin complexes (OPCs).

In fact, GSE is one of the best-known sources of proanthocyanidins.

Due to its high antioxidant content, GSE can help prevent disease and protect against oxidative stress, tissue damage, and inflammation.


Long hailed as the “king of spices,” black pepper is a staple seasoning in many households around the globe.

Its distinct flavor is due to the presence of piperine, a compound that has been linked to a long list of health benefits.

Because most of us only enjoy a dash or two of black pepper with each meal, some people opt to take a piperine supplement to boost their intake.

BioPerine is a patented piperine extract, containing at least 95% piperine in a form that is well absorbed by your body. It’s found in many supplements, either alone or alongside other ingredients like turmeric.

NitriLean Benefits

1. Lower Blood Pressure

High blood pressure can damage your blood vessels and heart. What’s more, it’s among the strongest risk factors for heart disease, stroke, and premature death worldwide.

Eating fruits and vegetables rich in inorganic nitrates may cut your risk of heart disease by lowering blood pressure and increasing nitric oxide formation.

NitriLean contains beetroots. Studies show that beetroots or their juice can reduce blood pressure by up to 3–10 mm Hg over a period of a few hours.

Such effects are likely due to increased levels of nitric oxide, which causes your blood vessels to relax and dilate.

2. Increased Exercise Capacity

Numerous studies suggest that nitrates can enhance physical performance, particularly during high-intensity endurance exercise.

Dietary nitrates have been shown to reduce oxygen use during physical exercise by affecting the efficiency of mitochondria, the cell organs responsible for producing energy.

NitriLean contains beetroots. Beets and their juice are often used for this purpose because of their high inorganic nitrate content.

Consumption of beetroots may improve running and cycling performance, increase stamina, boost oxygen use, and lead to better exercise performance overall.

3. May aid digestion

NitriLean contains hawthorn. People have used hawthorn berries and extract for centuries to treat digestive issues, particularly indigestion and stomach pain.

The berries contain fiber, which has been proven to aid digestion by reducing constipation and acting as a prebiotic. Prebiotics are foods that nourish and promote healthy gut bacteria, which are vital to maintaining healthy digestion.

One observational study in people with slow digestion found that each additional gram of dietary fiber people consumed was associated with a 30-minute decrease in the time between bowel movements.

In other words, the more fiber people ate, the more frequently they pooped.

Additionally, a rat study observed that hawthorn extract dramatically reduced the gut transit time of food in the digestive system.

Reduced gut transit time means food moves more quickly through the digestive system, which may alleviate indigestion.

Furthermore, research in rodents suggests that compounds in hawthorn berries could enhance the production and activity of digestive enzymes — namely those needed for the digestion of fatty and protein-rich foods.

4. May promote heart health

Oxidative stress increases fat buildup in your blood, which promotes inflammation in your arteries and leads to high blood pressure.

NitriLean contains green tea extract. The antioxidants in green tea extract can decrease inflammation and help reduce blood pressure. They can also inhibit fat absorption in cells, helping reduce blood fat levels.

In one 2012 study, 56 people with obesity and high blood pressure took 379 mg of green tea extract daily for 3 months. They showed a significant decrease in blood pressure, compared with the placebo group.

Additionally, they experienced significant reductions in blood fat levels, including lower triglycerides and both total and LDL (bad) cholesterol.

An older study in 33 people with no underlying health conditions found that taking 250 mg of green tea extract daily for 8 weeks reduced total cholesterol by 3.9% and LDL (bad) cholesterol by 4.5%.

Given that high blood pressure and high blood fat levels are risk factors for heart diseases, regulating them can promote heart health.

5. Can help with weight loss

NitriLean contains green tea extract. Green tea extract is rich in catechins, and it contains a decent amount of caffeine. Interestingly, it seems that this combination of ingredients is responsible for green tea extract’s modest weight loss properties.

Both catechins and caffeine have been shown to assist in weight loss by regulating the hormones that can enhance thermogenesis. Thermogenesis is the process by which your body burns calories to digest food and produce heat.

Green tea has been shown to boost this process by making your body more effective at burning calories, which can lead to weight loss.

In one older study, 14 people took a capsule containing a mixture of caffeine, EGCG from green tea, and guarana extract before each meal. It then examined the effect on calorie burning and found that the participants burned 179 more calories, on average, in the following 24 hours.

6. May reduce the risk of cancer

The maintenance of your body’s tissues and organs is characterized by cell death and regrowth. Specialized cells known as stem cells produce new cells to replace those that die. This process keeps cells active and healthy.

When this balance is disrupted, cancer can occur. This is when your body starts producing dysfunctional cells, and cells don’t die when they should.

NitriLean contains green tea extract. The antioxidants in green tea extract, especially EGCG, seem to have favorable effects on the balance of cell production and death.

One small older study explored the effects of taking 600 mg of green tea catechins per day for a year on men at risk of developing prostate cancer.

It found that the likelihood of developing cancer was 3% for the green tea group, compared with 30% for the control group.

7. May Reduce Your Appetite

NitriLean contains garcinia cambogia. Studies in rats show that those given garcinia cambogia supplements tend to eat less.

Similarly, some human studies have found that garcinia cambogia suppresses appetite and makes you feel full.

Its mechanism isn’t fully known, but rat studies suggest that the active ingredient in garcinia cambogia can increase serotonin in the brain.

Since serotonin is a known appetite suppressant, higher blood levels of serotonin could reduce your appetite.

8. May Block Fat Production and Reduce Belly Fat

NitriLean contains garcinia cambogia. Most importantly, garcinia cambogia impacts blood fats and the production of new fatty acids.

Human and animal studies show that it may lower high levels of fat in your blood and reduce oxidative stress in your body.

One study also suggests it may be especially effective at reducing the accumulation of belly fat in people who are overweight.

In one study, moderately obese people took 2,800 mg of garcinia cambogia daily for eight weeks and drastically improved several risk factors for disease:

  • Total cholesterol levels: 6.3% lower
  • “Bad” LDL cholesterol levels: 12.3% lower
  • “Good” HDL cholesterol levels: 10.7% higher
  • Blood triglycerides: 8.6% lower
  • Fat metabolites: 125–258% more excreted in the urine

The main reason for these effects may be that garcinia cambogia inhibits an enzyme called citrate lyase, which plays an important role in the production of fat.

By inhibiting citrate lyase, garcinia cambogia is thought to slow or block fat production in your body. This may reduce blood fats and lower your risk of weight gain — two major disease risk factors.

9. Can improve blood flow

NitriLean contains grape seeds. Some studies suggest that GSE may improve blood flow.

In an 8-week study in 17 healthy postmenopausal women, taking 400 mg of GSE had blood-thinning effects, potentially reducing the risk of blood clots.

An additional study in 8 healthy young women assessed the effects of a single 400-mg dose of proanthocyanidin from GSE immediately followed by 6 hours of sitting. It was shown to reduce leg swelling and edema by 70%, compared with not taking GSE.

In the same study, 8 other healthy young women who took a daily 133-mg dose of proanthocyanidins from GSE for 14 days experienced 40% less leg swelling after 6 hours of sitting.

NitriLean Cons and Complaints

1. Potential Side Effects

Although NitriLean supplements are all-natural, meaning they don’t contain any chemicals with crazy names that no one can pronounce, side effects are still a possibility. You may experience painful stomach aches, diarrhea, or excessive weight gain when you stop using NitriLean supplement. This is one reason why you should always consult your physician before taking them. He or she will help you determine which supplements are the safest for you.

2. May Disrupt Metabolism

Maintaining a healthy metabolism will allow you to more easily lose weight. NitriLean will suppress your appetite so that you’ll eat less food and, therefore, fewer calories. This is excellent when it comes to losing weight right away, but a big reduction of caloric intake will slow down your metabolism. This means that you may later find it more difficult to continue losing weight even with the NitriLean supplement because of your slower metabolism.

3. No Safety Regulation

Unlike prescription medication, which is heavily regulated by the FDA, over-the-counter dietary supplements for weight loss don’t have any standards that they must meet and don’t require their approval. However, the FDA does monitor the safety and efficiency of each supplement after it’s been released. If one is found to be unsafe, they will issue warnings or ask that it be taken off the market.

3. Only available on the official website

NitriLean can only be purchased through the official website, not through other eCommerce platforms like Amazon. Therefore, it may not be convenient for people.

However, I completely understand why NitriLean supplements only sell on its website. By following this practice, a counterfeit product can be prevented and product quality ensured.

4. Insufficient information about the manufacturer of NitriLean

In order to prevent copying, the Manufacturer does not disclose too much company information. However, NitriLean’s address can be found at the bottom of their website. This means you can contact the company if there is a problem with the product.

5. NitriLean does not work for some customers

There are a few customers who have called NitriLean a scam after not seeing results after a few weeks.

NitriLean researchers thoroughly researched their formula, which is designed to help people lose weight in a safe and effective way.

Because each person’s body is unique, there are many uncontrollable factors. NitriLean supplements cannot make a person lose weight if he or she does not exercise, consumes too much fat, or consumes too much sugar.

6. NitriLean is not cheap

As with many natural supplements, NitriLean isn’t cheap. Manufacturing costs and quality control are responsible for this. Since NitriLean supplements use natural ingredients, they tend to be more expensive.

It really depends on how important your health is to you. If you are willing to invest in your health, NitriLean is definitely worth the price.

7. Delay in delivery

Delivery delays are a common complaint among customers in remote areas or in developing countries.

eCommerce products commonly experience this issue. Global logistics is also affected by COVID 19. There are some areas that are blocked and fewer airlines flying. As a result, customers will experience shipping delays.

As good news, if you really can’t receive an order, you can request a refund. 

Generally, logistics shouldn’t be a problem if you live in a well-developed country, such as the US, United Kingdom, or Canada.

8. Unsuitable for children, pregnant women, or breastfeeding women

NitriLean is not for everyone. It contains natural ingredients that do not usually have any side effects, but it should not be used by women who are pregnant or breastfeeding.

Most other types of people are safe from NitriLean. All you need to do is follow the dosage instructions.

9. NitriLean is not a miracle cure

Don’t expect extraordinary results from taking just one NitriLean pill. They aren’t miracle cures.

Many factors contribute to effective weight loss. Even if you use NitriLean, you need to maintain healthy eating habits. It is not possible to consume a lot of fat and achieve results at the same time.

10. NitriLean requires regular intake

NitriLean does not produce results after a few doses, as with all supplements. In order to produce noticeable results, NitriLean must be consumed before bedtime every night.

Thus, if you want to lose weight and improve your health, you should not just buy one bottle. It’s not enough.

11. Several exaggerated claims have been made

Reviews of NitriLean sometimes exaggerate the benefits of the product in order to convince people to buy it. These are not reviews, but sales promotions.

It does not mean that NitriLean is a scam. Some marketers employ these tactics as part of their marketing strategy. NitriLean’s ingredients and the science behind them remain trustworthy.

Despite the complaints, NitriLean has a lot of positive testimonials. There is a high level of customer satisfaction with NitriLean.

Is NitriLean a Scam?

NitriLean is unquestionably not a scam. It’s a legit supplement that you can trust.

Frankly, it’s not always easy to tell the difference between beneficial products and scams. Don’t be a victim of clever marketing tricks that don’t deliver actual results. 

Sometimes, the same advertising messages that make us feel good about a product are red flags to watch out for.

The manufacturer of NitriLeans advocates for clean, natural products produced with transparency. That being said, reading a supplement label can be overwhelming.

Where do you start? How can you see through a supplement scam?

You can tell if NitriLean is a scam by looking at the following three things:

Does NitriLean Brand Make Its Supplements In The United States?

An important indication of the quality of dietary supplements is whether the company selling the product manufactures it in the United States. Production in the United States is a clear sign that the manufacturer’s top priority is high quality. Companies that move production overseas usually do so because production costs are much lower there. However, once a company outsources production, it loses control over the product. It’s no insight into the methods and materials used to manufacture it. All knowledge about the quality of the product is limited in favor of saving money on production.

However, when companies manufacture products in the U.S., they’ve complete control over every aspect of the product, from the design to the materials used. At every step of production, the company knows how the compound is made.

The NitriLean dietary supplement is manufactured in the United States in an FDA-approved facility in accordance with GMP standards. This shows that the company is committed to providing consumers with the highest quality product available. They’ve sent a message to consumers that price will never be more important than quality.

Does NitriLean Contain Artificial Ingredients?

Artificial ingredients are produced by chemical reactions that occur at high temperatures or high pressures. The compounds used to make artificial ingredients are not derived from natural foods but from chemicals. They can be harmful to the human body. 

You should be especially careful with artificial colors and flavors. Also, check carefully for

  • Rice flour (filler to make the capsule look full).
  • Gelatin (cheaper capsules that come from animal sources).
  • Carmine Color (used as a dye).

On closer inspection, we found that NitriLean contains only natural ingredients. No artificial colors, preservatives, or antibiotics are used in its production. 

Does NitriLean Use 3rd Party Testing?

A quality brand should have some type of third-party testing to verify its product. Third-party testing provides honesty and gives you, the consumer, peace of mind.

NitriLean has been tested for purity as no artificial colors, preservatives, or antibiotics were used in the manufacturing process. In addition, third-party inspectors are used throughout the year at their manufacturing facility to ensure they meet all current regulations.

What is the Relationship Between Nitric Oxide and Weight Loss?

The benefits of nitric oxide also include weight loss, athletic recovery, and others. By facilitating the flow of blood to all parts of your body, supplements like NitriLEAN improve the delivery of oxygen, nutrients, and other compounds carried in your blood.

To fuel your muscles and help you recover, your body needs to pump blood. Blood is supplied to your muscles when you exercise. Muscles are fueled by blood, which delivers oxygen and nutrients, making it easier to exercise (and squeeze out the last rep).

Blood is also essential for your body’s recovery. During recovery, your muscles need to be repaired. As a result, NitriLEAN uses the nutrients (carried by your blood) to repair and strengthen muscles.

Therefore, NitriLEAN and similar supplements might aid athletic recovery. You could enjoy powerful weight loss results if you combine your NitriLEAN regimen with an exercise regime.

Nitrilean Side Effects

When taken at the recommended doses, the ingredients in NitriLean supplement are generally safe to consume. However, you should bear in mind that some may cause side effects when used improperly.

For example, NitriLean contains Garcinia Cambogia. Garcinia Cambogia is likely safe for most people. However, in rare cases, common side effects of Garcinia include:

  • Nausea
  • Upset stomach
  • Diarrhea
  • Headache
  • Dizziness
  • Dry mouth

How Much Weight Can You Lose with NitriLEAN?

The sales page for NitriLEAN is filled with customer testimonials about how the supplement helped them lose significant amounts of weight. The stories make no mention of dieting or exercise. Instead, they simply started taking NitriLEAN and began losing weight.

According to testimonials on the NitriLEAN official website, you can lose the following amount of weight while taking NitriLEAN:

  • NitriLEAN allegedly helped one woman lose 25 pounds and 8 inches from her waist after she took it
  • Another woman claims to have lost 5lbs within the first few days of taking NitriLEAN. She eventually lost 29lbs and completely transformed her body within the next few weeks.
  • NitriLEAN helped a man from San Diego lose 30lbs “in just weeks”, losing a significant amount of weight at the age of 75
  • NitriLEAN helped another woman lose 29 lbs of belly fat and 7 dress sizes in just a few weeks
  • The makers of NitriLEAN believe that their formula can help you lose significant amounts of weight, including as much as 30lbs within weeks of taking NitriLEAN for the first time.

Is NitriLEAN Supplement Backed by Science?

On the official NitriLEAN website, there are dozens of studies on the individual ingredients.

Furthermore, all of the ingredients and dosages are disclosed upfront, making it simple to compare the results of the cited studies to those of NitriLEAN. NitriLEAN is a diet pill that contains ingredients that have been popular for decades, such as garcinia cambogia, L-citrulline, and cayenne pepper extract.

To begin, the ingredients in NitriLEAN increase blood flow and nitric oxide production to support cardiovascular health.

This 2018 study looked at the effect of beetroot juice supplementation on nitric oxide levels. A group of participants was given beetroot juice, and nitric oxide levels were measured exhaled at 45 and 90 minute intervals.

Participants’ nitric oxide levels increased by 21.3% after 45 minutes of consuming 70mL of beetroot juice, and by 20.3% after 90 minutes. The researchers discovered a 1% increase in the control group. These findings imply that beetroot juice supplements may increase nitric oxide levels in the blood.

A 2012 study found that nitric oxide supplements could improve human performance. The researchers administered nitric oxide supplements to healthy, trained volunteers and then watched their reactions.

Participants in the nitric oxide group improved their tolerance to aerobic and anaerobic exercise. L-citrulline, another ingredient in NitriLEAN, may act as a secondary nitric oxide supplement.

Green tea extract is abundant in NitriLEAN. Many people take green tea extract on a daily basis to help with weight loss, inflammation, and overall wellness. In this 2014 study, researchers reviewed the evidence supporting green tea’s weight loss effects.

The researchers looked at 14 randomized controlled trials with over 1,500 participants and discovered that people who drank green tea lost 0.2 to 3.5kg (0.44 to 7.7lbs) more than those who drank a placebo.

Green tea’s health benefits are attributed to its anti-inflammatory properties, according to researchers. According to this 2016 study, researchers discovered that green tea contains an anti-inflammatory catechin called EGCG.

Because of its anti-inflammatory properties, researchers believe this catechin may have anti-inflammatory properties.

Cayenne pepper extract, a popular weight-loss ingredient, is also included in NitriLEAN. Cayenne pepper contains capsaicinoids. Multiple studies have linked the capsaicinoids in these peppers (including capsaicin) to real weight loss results.

In this 2018 study, researchers looked at the weight loss effects of cayenne pepper extract after 12 weeks. According to the study, those who used cayenne pepper lost 6.68 percentage points more weight than those who used a placebo.

Several studies have linked the ingredients in NitriLEAN to weight loss. NitriLEAN’s ingredients may aid in weight loss in more than one way.

4 thoughts on “NitriLEAN Review – Scam or Legit? Exposed!”

  1. So it took about 3 weeks to notice any progress but when it did it was noticeable. I walk for 30 minutes about 5 days a week and watch my calorie I take vs my output. Well I hurt my foot so had to be idle about a week and was taking these and still noticed the weight coming off! I weigh myself every morning and it doesn’t go fast but it does seem to come off consistently each day. Definitely give it time because it didn’t work for me within the 2 weeks other people said did for them.

    • I perform my due diligence just to be safe before buying any supplements. There are a lot of products out there that promise weight loss even without putting in the work. But this product has helped me burn more calories.

  2. I am on my 26th day with only 4 doses left using this new product to help with personal body maintenance. I am in my late 40s so metabolism and hormones have been naturally declining. With that comes weight gain. I have tried many other products with fat burning blends, appetite suppressants, and thermogenic compositions that have seem to work in the beginning but eventually reach an adaptive body response or plateau. However, NitriLean has been consistently meeting my expectations during the past few weeks. I have lost 7 lbs of fat so far in my abdomen, facial structure, and flatter man boobs. I am impressed with this product so far.
