Fighters Core Ingredients

Fighters Core contains herbal and plant extracts, vitamins, minerals, and other ingredients linked to fat burning.

Each ingredient in Fighters Core targets weight loss differently. Here’s how each ingredient works, according to the makers of Fighters Core:

Forskolin: Fighters Core can purportedly impact key hormonal messengers, increasing metabolic rate and boosting fat burning. In some studies, researchers have found that forskolin leads to fat reduction and increased levels of lean muscle mass, among other benefits.

Caffeine: Caffeine is found in many fat burner supplements sold online today – and for a good reason. Caffeine is a popular thermogenic and metabolism booster. It boosts your metabolism, forcing your body to burn more calories at rest. Fighters Core contains 25mg of caffeine anhydrous, which is less than the amount of caffeine in half a cup of coffee. However, it also contains additional caffeine from the green tea extract within the formula.

Calcium HMB: Fighters Core contains calcium HMB, a powerful compound that can inhibit muscle breakdown during fasted training, helping you perform at your best, burn more calories with every workout, and get leaner, stronger, and faster. The makers of Fighters Core claim this specific version of calcium can promote muscle growth and recovery while preventing the breakdown of key proteins. That means you burn fat while preserving muscle mass.

Green Tea Extract: Fighters Core contains green tea extract. Green tea extract is rich in polyphenols like EGCG. Polyphenols are plant-based antioxidants that support inflammation throughout your body. Multiple studies have also connected the EGCG in green tea to weight loss. Many people take green tea extract daily for weight loss for that reason. According to the makers of Fighters Core, the catechins (like EGCG) in green tea are associated with fat breakdown and improved metabolism.

Chromium Picolinate: Fighters Core contains a substantial dose of chromium. Some people with diabetes take chromium to manage blood sugar. In non-diabetics, chromium can stop fat storage, boost energy levels, and keep hunger in check. Chromium helps with fat burning because it helps people with diabetes: chromium is crucial for managing blood sugar. If your blood sugar levels are imbalanced, then you experience food cravings and other issues. Fighters Core contains chromium picolinate to support appetite, muscle, and energy.

Capsimax: Capsimax is another popular fat-burning supplement ingredient. It’s a trademarked type of pepper extract with a specific amount of capsaicin. Capsaicin is the active ingredient in pepper that gives it a spiciness. Capsimax can purportedly help your body release fat-fighting hormones. By promoting the breakdown of fats before and after training, Capsimax can help you lose weight while also increasing the number of calories you lose each day.

Overall, Fighters Core contains a blend of fat-burning ingredients similar to what we see in other nutritional supplements sold online today. By taking three capsules of Fighters Core daily, you can support your body’s ability to burn fat while preserving your lean muscle mass at the same time, making it ideal for anyone who wants to lose weight without cutting away muscle.

Scientific Evidence for Fighters Core

PFX Labs has not conducted clinical trials on Fighters Core, nor have published peer-reviewed research in a journal verifying their weight-loss claims. However, the company has used science-backed ingredients in the formula, including ingredients that have completed studies to verify their weight loss effects. PFX Labs also discloses all dosages upfront, making it easy to see exactly how much each ingredient is in the formula.

The biggest ingredient in Fighters Core is green tea extract. Each serving contains 400mg of green tea extract. Multiple studies have validated the weight loss effects of green tea. As the Cleveland Clinic explains, the epigallocatechins-3-gallate (EGCG) in green tea extract is the catechin with strong antioxidant potential. Antioxidants support healthy inflammation throughout your body, which can help with weight loss, endurance, and more.

In this 2013 study published in Advances in Nutrition, researchers found that green tea extract impacted fat oxidation at rest and during exercise. Participants taking green tea extract had higher fat oxidation rates than normal after taking green tea extract, suggesting that green tea extract increased fat burning.

Green tea extract contains EGCG and caffeine, and Fighters Core contains an additional 25mg of caffeine to complement this dose. Caffeine is one of the most popular and proven thermogenic fat-burning ingredients available. Many people enjoy the fat-burning benefits of caffeine daily without thinking about it.

In this 2005 study, researchers told 76 overweight and moderately obese subjects to take a combination of green tea and caffeine. Participants took 270mg of EGCG from green tea extract and 150mg of caffeine per day or a placebo. After four weeks, researchers found that the green tea extract and caffeine group had lost more weight, fat mass, and waist circumference than the placebo group. Researchers concluded that high caffeine intake was associated with weight loss through thermogenesis and fat oxidation. Researchers also found that the combination of green tea extract and caffeine suppressed leptin in women. This is similar to the combination in Fighters Core, and it’s possible Fighters Core delivers similar weight loss benefits.

Fighters Core also contains a significant dose of chromium picolinate. Chromium is found in many diabetic supplements because it’s linked to blood sugar management. However, some studies have found a connection between chromium and weight loss. In this 2010 review, researchers analyzed 10 double-blind, placebo-controlled trials on chromium picolinate and weight loss. Overall of these trials, researchers found chromium supplementation led to an average weight loss of 1.1 to 1.2kg (2.4 to 2.6lbs) over a 10 to 13 week period. You can get chromium in any multivitamin, although Fighters Core has a substantial dosage of chromium.

Fighters Core also contains Capsimax, a type of capsaicin formula found in other weight loss pills. Capsaicin is the active ingredient in chili pepper that makes it spicy. Studies show that the same ingredient that gives chili pepper its spiciness can increase fat burning and fat oxidation. In this 2017 study, researchers found that capsaicin had numerous roles in health, including proven anti-obesity effects.

Overall, Fighters Core contains a blend of ingredients linked to weight loss. The supplement contains good, normal dosages of each ingredient, including strong doses of chromium and green tea extract. It’s possible that Fighters Core can help you lose weight when taken daily.
