Does NitriLEAN really work? Or is NitriLEAN yet another weight loss supplement scam? Keep reading to discover everything you need to know about NitriLEAN and its effects.


What is NitriLEAN?

NitriLEAN is a diet pill sold exclusively online on the official website. By taking two capsules of NitriLEAN daily, you can purportedly support heart health, boost metabolism, reduce excess belly fat, and support healthy blood flow, among other benefits.

To achieve these benefits, NitriLEAN uses a collection of eight natural ingredients, including plant extracts, herbal extracts, vitamins, and minerals. The proprietary formula is exclusive to NitriLEAN. You cannot find the formula anywhere in stores.

NitriLEAN is priced at around $59 per bottle. Each bottle contains a one-month supply of formula (60 capsules or 30 servings).


How Does NitriLEAN Work?

The makers of NitriLEAN claim their formula can have powerful effects across the body. The makers of NitriLEAN advertise the formula as more than just a weight loss aid: they also claim it can support heart health and blood flow. And, by helping you lose weight, NitriLEAN can even purportedly help you stop worrying about a heart attack.

The NitriLEAN.com sales page is filled with before and after images of people who have lost a significant amount of weight by taking NitriLEAN. According to the official website, customers have lost anywhere from 25 to 29lbs by taking NitriLEAN.

Overall, the makers of NitriLEAN claim the formula will help you “feel your body become leaner, healthier and rejuvenated” with each passing day. By taking two capsules of NitriLEAN daily, you can enjoy powerful weight loss benefits and other effects.

Benefits of Nitric Oxide Supplements

NitriLEAN is a combination of two supplements: a diet pill and a nitric oxide supplement. That’s why NitriLEAN claims to support cardiovascular health (by acting as a nitric oxide supplement and widening blood vessels) while also helping you lose weight (using green tea extract, cayenne pepper, and other ingredients).


To support nitric oxide production in the body, NitriLEAN uses ingredients like beetroot extract. Beets have been proven to raise nitric oxide levels in multiple studies.

Nitric oxide is a vasodilator, which means it relaxes the inner muscles of your blood vessels, allowing them to widen. In fact, drugs like Viagra use the power of nitric oxide to enhance sexual performance – and some people take beetroot extract daily for similar reasons.

By widening blood vessels, it’s possible for nitric oxide supplements to lower blood pressure. When blood vessels are tight and narrow, your heart needs to work harder to pump blood. When blood vessels are wide and flexible, it’s easier for your heart to pump blood.

That’s why NitriLEAN claims to support cardiovascular health.

Nitric Oxide and Weight Loss

Nitric oxide can also help with weight loss, athletic recovery, and other benefits. By making it easier to pump blood to all corners of your body, supplements like NitriLEAN could assist in the flow of oxygen, nutrients, and other compounds carried in your blood.

Your body needs to pump blood to fuel muscles and help you recover. Your body pumps blood to muscles during exercise. Blood carries oxygen and nutrients to fuel muscles, making it easier to work out (and squeeze out that last rep).

Similarly, your body needs blood for recovery. As your body recovers, it needs to repair muscles. To do that, NitriLEAN uses the nutrients (carried by your blood) to repair muscles and help them grow.

For that reason, NitriLEAN and similar supplements could help with athletic recovery. If you’re complementing your NitriLEAN regimen with an exercise routine, then you could lose weight from multiple angles, enjoying powerful weight loss results.

NitriLEAN Ingredients

All weight loss supplements claim to help you quickly and easily lose weight. Unfortunately, many of these supplements don’t work. NitriLEAN claims to be different. The company discloses its full list of ingredients and dosages upfront, making it easy to verify the supplement’s effects based on scientific research and studies.

Here are all of the ingredients in NitriLEAN and how they work, according to the official website:

Green Tea Extract (500mg)

The largest ingredient in NitriLEAN is green tea extract. There’s twice as much green tea extract in NitriLEAN as any other ingredient. Each serving contains 500mg of green tea extract standardized to contain 50% epigallocatechin gallate (EGCG), the active ingredient in green tea. EGCG is linked with antioxidant effects and fat burning. According to the makers of NitriLEAN, the green tea in their formula works as a “powerful metabolism booster and natural antioxidant,” helping to boost metabolism and force your body to burn fat for energy, among other benefits.

L-Citrulline (220mg)

NitriLEAN contains 200mg of L-citrulline, a powerful amino acid found in many pre-workout formulas for its effects on nitric oxide production. By supporting nitric oxide production in your body, NitriLEAN can purportedly widen blood vessels, increasing pump and vascularity before a workout. In NitriLEAN, these same effects boost blood flow throughout your body, increasing energy and making it easier to lose weight.

Hawthorn (100mg)

NitriLEAN contains 100mg of hawthorn extract. The company added this ingredient specifically for heart health, claiming the ingredient “is proven to support a healthy heart.” They also claim to use an “ultra-rare, pure hawthorn extract that can help you support your health and fitness goals.

Beet Root (100mg)

NitriLEAN contains 100mg of beetroot extract to support nitric oxide levels, blood pressure, blood sugar, circulation, and sexual performance, among other benefits. Many people take beetroot daily for blood flow. The makers of NitriLEAN claim to use “the purest grade naturally sourced beetroot available,” maximizing the blood flow effects of NitriLEAN.

Garcinia Cambogia (100mg)

Garcinia cambogia has been one of the trendiest diet pill ingredients of the last decade. According to the makers of NitriLEAN, garcinia cambogia can inhibit the enzymes involved in fat production while boosting metabolism and energy. The company also claims their garcinia cambogia can support healthy cholesterol levels and appetite, support blood sugar and insulin response, and provide other benefits.

Cayenne Pepper (50mg)

NitriLEAN contains 50mg of cayenne pepper extract. Many diet pills use cayenne pepper extract because of the strong presence of capsaicin, the natural ingredient that gives chili pepper its spice. This ingredient has been shown to help with thermogenic fat burning, making it easier to lose weight by burning fat from the inside out.

Grape Seed Extract (50mg)

NitriLEAN contains 50mg of grape seed extract. The grape seed extract is rich in polyphenols, which are natural fruit chemicals with antioxidant effects. According to the makers of NitriLEAN, the grape seed extract in their formula can “significantly support” blood flow and cardiovascular health.

Bioperine (5mg)

Like many diet pills sold online today, NitriLEAN contains a small dose of black pepper extract in the form of Bioperine. This extract has been shown to increase the absorption of other ingredients. Many garcinia cambogia diet pills, for example, contain Bioperine for its effects on bioavailability. According to the makers of NitriLEAN, the Bioperine in their formula “works to significantly improve the bioavailability of all other nutrients,” leading to better absorption and effectiveness.

How Much Weight Can You Lose with NitriLEAN?

The NitriLEAN sales page is filled with stories of customers losing significant amounts of weight by taking NitriLEAN. None of the customers claim to have dieted or exercised. Instead, they simply started taking NitriLEAN – then lost substantial amounts of weight.


Here’s how much weight you could lose while taking NitriLEAN, according to testimonials shared on the NitriLEAN official website:

  • One woman from Austin, Texas claims she lost 25lbs and 8 inches from her waist after taking NitriLEAN
  • Another woman claims she lost 5lbs in the first few days of taking NitriLEAN, ultimately losing 29lbs and completely transforming her body over the next few weeks
  • One man from San Diego lost 30lbs “in just weeks” of taking NitriLEAN, losing a significant amount of weight at age 75
  • Another woman lost 29lbs of belly fat and 7 dress sizes in just a few weeks of taking NitriLEAN

Overall, the makers of NitriLEAN are confident you can lose significant amounts of weight using their formula, including as much as 30lbs within weeks of taking NitriLEAN for the first time.


Scientific Evidence for NitriLEAN

The NitriLEAN official website has a references page featuring dozens of studies on the individual ingredients within NitriLEAN. The company also discloses all ingredients and dosages upfront, making it easy to compare the cited studies to the effects of NitriLEAN. Overall, NitriLEAN contains some of the most popular diet pill ingredients of the last decade, including proven compounds like L-citrulline, garcinia cambogia, and cayenne pepper extract.

First, many of the ingredients in NitriLEAN target vascularity and blood flow, raising nitric oxide production to help support cardiovascular health.

In this 2018 study, researchers tested the effects of a beetroot juice supplement on nitric oxide levels. Researchers gave beetroot juice to a group of participants, then measured exhaled nitric oxide levels at intervals of 45 and 90 minutes. After ingesting 70mL of beetroot juice, participants had 21.3% higher nitric oxide levels 45 minutes after consumption and 20.3% higher nitric oxide levels 90 minutes after consumption. In the control group, researchers observed a less than 1% increase. Based on these results, beetroot juice supplements could raise nitric oxide levels in the blood.

Meanwhile, this 2012 study found that nitric oxide supplements could have real impacts on human performance. Researchers gave nitric oxide supplements to healthy, trained participants, then observed the effects. Researchers found that participants in the nitric oxide group could improve tolerance to aerobic and anaerobic exercise. Researchers also found that L-citrulline, another ingredient in NitriLEAN, could act as a secondary nitric oxide supplement.

The biggest ingredient in NitriLEAN is green tea extract. Many people take green tea extract daily for weight loss, inflammation, and overall health and wellness. In this 2014 study, researchers reviewed the evidence on green tea and weight loss. After analyzing 14 randomized controlled trials involving 1,500+ participants, researchers found that people in the green tea group lost 0.2 to 3.5kg (0.44 to 7.7lbs) more than a placebo group, on average.

Studies trace the benefits of green tea to its anti-inflammatory actions. As explained in this 2016 study, researchers found that green tea is rich in anti-inflammatory catechin called EGCG. This catechin has anti-inflammatory effects, leading researchers to conclude that the ingredient could have “beneficial effects…against inflammatory diseases.”

NitriLEAN also contains popular weight loss ingredients like cayenne pepper extract. Cayenne pepper is rich in capsaicinoids. These capsaicinoids (including capsaicin) have been linked with real weight loss results in multiple studies. In this 2018 study, researchers gave participants cayenne pepper extract, then studied the weight loss effects after 12 weeks. Researchers found that the cayenne pepper group experienced weight loss that was 6.68 percentage units better than patients taking a placebo.

Overall, NitriLEAN contains popular ingredients linked to weight loss in multiple studies. It’s possible the ingredients in NitriLEAN could help with weight loss in multiple ways.
