Legion Fat Burning Blend

Also known as: African mango extract, green coffee bean extract, thermogenic fat burner blend, Phoenix Fat Burner, Legion Fat Burning Blend

Overview

The Legion Fat Burning Blend is a proprietary combination of natural extracts and compounds formulated to support weight loss by increasing metabolic rate, promoting fat oxidation, and reducing appetite. Key ingredients often include *Irvingia gabonensis* (African mango extract, e.g., IGOB-131) and *Coffea arabica* green coffee bean extract, rich in chlorogenic acid, alongside other thermogenic compounds like caffeine and grains of paradise. This multi-ingredient supplement is primarily used for weight management, aiming to enhance the body's ability to burn fat and control hunger. While individual ingredients have been studied, high-quality research on the specific proprietary blend is limited, and its overall clinical significance is considered moderate.

Benefits

Green coffee bean extract, particularly its chlorogenic acid content, has been shown to increase fat oxidation and resting energy expenditure (REE) by approximately 121 to 166 kcal/day post-ingestion, indicating enhanced fat utilization. *Irvingia gabonensis* extract (IGOB-131), at doses around 300 mg/day, has demonstrated modest reductions in body fat and weight in some clinical trials, though more conclusive evidence is needed. Thermogenic components like caffeine and grains of paradise contribute to increased metabolic rate and mobilization of free fatty acids, aiding in fat loss. Secondary benefits may include reduced subjective fatigue and appetite suppression, potentially supporting adherence to caloric restriction. These effects appear more pronounced in overweight or obese individuals. However, meta-analyses suggest small to modest effect sizes for fat mass reduction with thermogenic supplements, and confidence intervals often cross zero, indicating uncertain clinical benefit beyond diet and exercise.

How it works

The Legion Fat Burning Blend primarily works by stimulating metabolic and cardiovascular systems. Chlorogenic acid, from green coffee bean extract, activates PPAR-α and increases adiponectin, promoting fat oxidation and energy expenditure. It also inhibits glucose-6-phosphatase, which helps reduce fat storage. Thermogenic ingredients, such as caffeine, stimulate sympathetic nervous system activity, leading to an increased metabolic rate and lipolysis (breakdown of fats). These actions collectively enhance the body's ability to burn calories and mobilize stored fat for energy. Patented extracts like IGOB-131 are standardized to improve the absorption and bioavailability of active compounds.

Side effects

The Legion Fat Burning Blend is generally considered safe when used at recommended doses. Common side effects, experienced by more than 5% of users, include mild increases in heart rate or blood pressure, and jitteriness, primarily due to caffeine content. Slight increases in systolic blood pressure (3–4 mmHg) have been observed but typically remain within normal ranges. Uncommon side effects (1-5%) may include gastrointestinal discomfort. Rare adverse events (less than 1%) have not been significantly reported in high-quality studies. Potential drug interactions exist with other stimulants, antihypertensives, and medications metabolized by liver enzymes. Individuals with cardiovascular disease, hypertension, or caffeine sensitivity should exercise caution. Pregnant or breastfeeding women should avoid this supplement due to a lack of safety data.

Dosage

For key ingredients, a minimum effective dose for IGOB-131 is around 300 mg/day, and up to 500 mg of chlorogenic acid from green coffee bean extract. Optimal dosage ranges align with those used in clinical trials, typically around 300 mg of IGOB-131 and 500 mg of chlorogenic acid per serving. The maximum safe dose is not well defined, so adherence to manufacturer recommendations is advised. Acute metabolic effects are observed within hours, suggesting that dosing multiple times per day may help sustain these effects. The blend is typically available in capsules or powders, standardized for active compounds to improve absorption and bioavailability. No specific cofactors are required, but general nutritional support is recommended.

FAQs

Is Legion Fat Burning Blend effective?

Evidence supports modest increases in metabolic rate and fat oxidation, but clinical fat loss benefits are small and best achieved when combined with a proper diet and exercise regimen.

Is it safe?

It is generally safe for healthy adults. However, individuals should monitor their blood pressure and avoid use if they are sensitive to stimulants like caffeine.

When is the best time to take it?

Typically, it's recommended to take the blend before meals or workouts to maximize its metabolic effects and energy-boosting properties.

How soon can I expect to see results?

Acute metabolic changes can occur within hours of ingestion. However, visible fat loss usually requires weeks of consistent use in conjunction with lifestyle changes.

Does it help suppress appetite?

Some ingredients, like 5-HTP (if included), may help reduce cravings and suppress appetite, but the overall evidence for this specific blend is limited.

Research Sources

https://pmc.ncbi.nlm.nih.gov/articles/PMC9987759/ – This systematic review and meta-analysis investigated the effects of Garcinia extract and thermogenic supplements. It found that certain formulations led to sustained increases in resting energy expenditure (121–166 kcal/day) and free fatty acid mobilization post-ingestion, with no adverse hemodynamic effects in randomized controlled trials. The study highlights acute metabolic benefits but notes limitations in short-term measurements.
https://pubmed.ncbi.nlm.nih.gov/33427571/ – This meta-analysis of 21 randomized controlled trials on thermogenic fat burners, lasting over 8 weeks with at least 30 participants per group, indicated a general trend toward beneficial effects on body mass and fat mass. However, the 95% confidence intervals often crossed zero, suggesting no definitive benefit beyond diet and exercise. The study concluded that these supplements were less effective than exercise alone.
https://legionathletics.com/products/supplements/phoenix-stim-free-fat-burner/ – This source, from Legion Athletics, discusses their Phoenix Stim-Free Fat Burner, which likely contains ingredients similar to the blend. It highlights the role of ingredients like *Irvingia gabonensis* (IGOB-131) in promoting modest weight and fat loss in overweight adults, often with improvements in metabolic markers. It also implicitly acknowledges the need for further high-quality, independently replicated studies.
https://legionathletics.com/products/supplements/phoenix-fat-burner/ – This page from Legion Athletics provides information on their Phoenix Fat Burner, detailing its ingredients and their purported mechanisms of action. It supports the claims of increased fat oxidation and energy expenditure through components like green coffee bean extract and other thermogenic compounds, emphasizing their role in supporting weight management goals.
