NitriLEAN: Review the Weight Loss Metabolism Booster Formula

NitriLEAN is a natural weight loss support hormone formula that works to boost metabolism, burn fat and blood flow by increasing nitric oxide levels with 8 special ingredients in this health supplement.


NitriLEAN is a diet pill that claims to boost your metabolism while reducing excess belly fat.

By taking two capsules of NitriLEAN per day, you can purportedly increase metabolism, enhance fat loss, support healthy blood flow, and enjoy other benefits using an all-natural formula.

Is NitriLEAN yet another overpriced and over-hyped diet pill? Or is NitriLEAN a genuine weight loss breakthrough? Find out everything you need to know about NitriLEAN and how it works today in our review.

What is NitriLEAN?

NitriLEAN is a diet pill sold online through, where it’s priced at $60 per bottle.

Each bottle of NitriLEAN contains natural ingredients that purportedly increase your metabolism, making it easier for your body to burn fat and lose weight.

The all-natural, vegetarian formula is not available in stores or through other retailers online. It’s only available through the official website.

As the name suggests, NitriLEAN particularly focuses on nitric oxide (NO) levels within your body, using ingredients like beet extract and amino acids to raise NO levels, supporting healthy blood flow.

Obviously, all diet pills make similar claims, suggesting you can easily lose weight just by taking one or two capsules per day. Does NitriLEAN really work? Let’s take a closer look at the mechanisms behind this supplement.

How Does NitriLEAN Work?

The makers of NitriLEAN claim their formula is more than just a weight loss aid: it’s also shown to support a healthy heart, support blood flow, and specifically target belly fat, among other benefits.

Here are some of the advertised benefits of NitriLEAN, according to the official sales page:

  • Enhance fat loss
  • Increase metabolism
  • Support healthy blood flow and heart health
  • Completely safe with zero side effects
  • High potency, pure, 100% natural ingredients guaranteed to work

To back up its claim, NitriLEAN comes with a 60 day refund policy. You can request a complete refund on NitriLEAN within 60 days with no questions asked. That’s a good refund policy, although it’s similar to the refund policy offered by most other nutritional supplements.

To achieve these benefits, NitriLEAN contains eight nutrients “in the exact amount needed to support a healthy heart and naturally increase fat burning,” according to the official website.

The website adds that the formula is a “health game changer,” particularly for men and women over age 30.

Obviously, these are all bold claims to make. We’ve seen other diet pills advertise weight loss benefits, but NitriLEAN claims to offer far more than just weight loss.

Let’s take a closer look at the ingredients within NitriLEAN to verify the science behind this formula

NitriLEAN Ingredients

NitriLEAN contains eight ingredients that can purportedly kickstart weight loss, increase metabolism, and support heart health and blood flow, among other benefits.

The makers of NitriLEAN disclose all dosages upfront, making it easy to see how NitriLEAN compares to other supplements and to scientific studies. Many diet pills hide dosages within proprietary formulas, but NitriLEAN uses a different approach – and we appreciate this level of transparency.

Here are the ingredients within NitriLEAN and how they work:

Cayenne Pepper: NitriLEAN contains 50mg of cayenne pepper extract. Many diet pills contain cayenne because it has an active ingredient called capsaicin, which has been shown to boost metabolism in various ways and accelerate fat burning.

Hawthorn: NitriLEAN contains 100mg of hawthorn extract, which is shown to support heart health.

L-Citrulline: Many athletic supplements contain L-citrulline, an amino acid commonly used to raise nitric oxide levels and enhance blood flow. You can find preworkout supplements with 1,000mg doses of L-citrulline or higher, although NitriLEAN contains 220mg of the amino acid.

Bioperine: Bioperine is a type of black pepper extract found in many nutritional supplements. Bioperine has been shown to increase bioavailability of certain other ingredients, helping your body absorb the active chemicals in other NitriLEAN ingredients.

Beet Root: Beet root is one of the most popular nitric oxide boosters available in the nutritional supplement space. Studies show beet root can help support nitric oxide production, which is linked with blood flow. NitriLEAN contains 100mg of beet root extract, which is linked with blood pressure, blood sugar, circulation, and sexual performance, according to the makers of NitriLEAN.

Green Tea Extract: NitriLEAN contains 500mg of organic green tea extract that contains 50% EGCG. EGCG is a natural antioxidant shown to increase metabolism, helping your body burn more fat as energy, among other benefits.

Garcinia Cambogia: Garcinia cambogia has been a popular diet pill ingredient for years. NitriLEAN contains 100mg of garcinia cambogia, which could work by inhibiting the activity of a fat-forming enzyme – or by suppressing appetite.

Grape Seed Extract: Each serving of NitriLEAN contains 50mg of grape seed extract and grape seed skin extract, polyphenol-rich extracts that support blood flow and cardiovascular health, among other benefits.

Scientific Evidence for NitriLEAN

NitriLEAN has not completed any clinical trials, nor has the company published any research online. However, the company cites third party studies performed on individual ingredients within the formula. We’ll evaluate some of that evidence below to determine if NitriLEAN works as advertised.

First, many people take beets and beet extract to support cardiovascular health. As WebMD explained in a 2015 article, beet juice boosts muscle power in heart patients. Beet juice works because it has a high concentration of nitrates, which boosts muscle strength. Your body processes nitrates into nitric oxide, and nitric oxide (NO) relaxes blood vessels and improves metabolism, among other benefits. Various studies have shown beet extract can genuinely widen blood vessels.

Typically, beet supplements use a dose of 1,000mg to 2,000mg per serving – similar to the dose used in most studies. NitriLEAN contains just 100mg of beet extract.

NitriLEAN does, however, contain a significant dose of green tea extract with 50% EGCG. Numerous studies have connected green tea extract and EGCG to metabolism, weight loss, and other effects. Specifically, green tea extract seems to help with weight loss by increasing metabolism and fat oxidation, literally encouraging your body to burn fat as you exercise. This 2010 review study analyzed dozens of studies and found that green tea had significant potential to treat metabolic syndrome, obesity, diabetes, and cardiovascular risk factors.

NitriLEAN also contains a significant dose of L-citrulline, a popular amino acid for supporting blood flow. As this 2018 study explained, L-citrulline is a well-tolerated supplement ingredient linked with nitric oxide synthesis in the body. Many preworkout supplements contain a combination of L-citrulline and L-arginine, both of which are linked to nitric oxide and blood flow.

Overall, NitriLEAN contains several ingredients that target nitric oxide levels, which could support blood flow, help you exercise more, boost endurance, and support heart health, among other benefits.

Given the high price, we’re surprised by the relatively low doses of the formula, although it could work as advertised to support a range of benefits (although you can find preworkout supplements for half the price with higher dosages of similar ingredients).

NitriLEAN Pricing

NitriLEAN is priced at $49 to $59 per bottle, depending how many bottles you order. You can exclusively order through the official website at, where pricing breaks down like this:

  • 1 Bottle: $59
  • 3 Bottles: $147
  • 6 Bottles: $264

All prices include shipping to the United States.

Oddly, the official website claims the ‘normal price’ is $497. There’s no evidence that NitriLEAN has ever been priced above $59 per bottle, and even $59 per bottle seems high given the relatively low doses within the supplement.

NitriLEAN Refund Policy

NitriLEAN has a 60 day money back guarantee. You can request a complete refund on your purchase within 60 days with no questions asked.

You need to ship your NitriLEAN bottle (or bottles) back to the returns address to complete the refund process – even if the bottles are empty.

Who’s Behind NitriLEAN?

The makers of NitriLEAN provide limited information about themselves, the manufacturing location, or other information about the supplement.

In fact, all we really know about the makers of NitriLEAN is that you can contact the company via email:


The company also claims to manufacture NitriLEAN in an FDA-registered, GMP-certified facility.

Final Word

NitriLEAN is a diet pill that claims to lose weight, support blood flow, and provide other benefits.

Overall, NitriLEAN contains a range of ingredients similar to what we see in other diet pills or heart supplements – including garcinia cambogia, beet root, and cayenne. Although dosages are slightly lower than other diet pills or preworkout supplements, NitriLEAN could support its advertised benefits – and the supplement also has a 60 day money back guarantee backing up its claims.
