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.

 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.

 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.

 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 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.

 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.

 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.

 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.
