Transparency is a core principle at CitrusBurn. Unlike supplements that hide behind proprietary blends, every ingredient and its exact dosage is clearly listed. Below you'll find a detailed breakdown of each component, what it does, and the published research supporting its inclusion.
1. Citrus Bioflavonoids — 500 mg
What It Is
Bioflavonoids are a class of polyphenolic compounds found in the peels and membranes of citrus fruits including oranges, lemons, grapefruits, and limes. The specific bioflavonoids used in CitrusBurn include hesperidin and naringin, both of which have been studied extensively for their metabolic and anti-inflammatory properties.
How it works: Citrus bioflavonoids activate enzymes involved in fatty acid oxidation (the process of breaking down stored fat for energy) and stimulate thermogenesis by supporting brown adipose tissue activity. They also reduce systemic inflammation, which is increasingly recognised as a driver of metabolic dysfunction.
Research: A study published in the Journal of Nutritional Biochemistry found that hesperidin supplementation significantly improved lipid profiles and reduced markers of oxidative stress in overweight adults. Additional research in the International Journal of Molecular Sciences highlights naringin's role in modulating adipocyte metabolism. You can explore related studies on PubMed.
2. Garcinia Cambogia 60% HCA — 400 mg
What It Is
Garcinia Cambogia is a tropical fruit native to Southeast Asia. Its rind contains hydroxycitric acid (HCA), which has been the subject of numerous weight-management studies. CitrusBurn uses a standardised extract delivering 60% HCA per dose.
How it works: HCA inhibits citrate lyase, an enzyme that converts excess carbohydrates into fat. By blocking this pathway, more carbohydrates are directed toward glycogen (energy storage in muscles) rather than adipose tissue. HCA also supports serotonin production, which helps reduce emotional eating and stress-related food cravings.
Research: A systematic review published in the Journal of Obesity analysed multiple randomised controlled trials and found that Garcinia Cambogia supplementation produced statistically significant reductions in body weight compared to placebo. The World Health Organization recognises the importance of managing appetite as a key factor in global obesity prevention strategies.
3. Green Tea Extract 50% EGCG — 300 mg
What It Is
Green tea extract is derived from the leaves of Camellia sinensis and is standardised to contain 50% EGCG (epigallocatechin gallate), the most bioactive and well-researched catechin in green tea.
How it works: EGCG boosts thermogenesis by inhibiting catechol-O-methyltransferase (COMT), an enzyme that normally breaks down norepinephrine. With COMT inhibited, norepinephrine remains active longer, stimulating fat cells to release stored fatty acids for energy. Meta-analyses suggest EGCG can increase metabolic rate by 3–4% and enhance fat oxidation during both rest and exercise.
Research: A comprehensive meta-analysis in the American Journal of Clinical Nutrition confirmed that green tea catechins significantly reduce body weight and help maintain weight loss over time. The NIH Office of Dietary Supplements provides detailed monographs on green tea's safety and efficacy profile.
4. Chromium Picolinate — 200 mcg
What It Is
Chromium is an essential trace mineral. The picolinate form offers superior bioavailability compared to other chromium supplements, meaning your body absorbs and utilises it more efficiently.
How it works: Chromium enhances the action of insulin, the hormone responsible for shuttling glucose from the bloodstream into cells. By improving insulin sensitivity, chromium helps prevent the blood sugar spikes and crashes that trigger carbohydrate cravings and promote fat storage. It also supports healthy cholesterol levels.
Research: The NIH Chromium Fact Sheet cites several studies showing improved glycaemic control with chromium picolinate supplementation. A trial published in Diabetes Technology & Therapeutics found significant improvements in fasting blood glucose and insulin levels.
5. Cayenne Pepper Extract — 150 mg
What It Is
Cayenne pepper extract provides capsaicin, the compound responsible for the "heat" in chilli peppers. In supplement form, it delivers thermogenic benefits without the burning sensation of eating raw peppers.
How it works: Capsaicin activates transient receptor potential vanilloid 1 (TRPV1) receptors, triggering a mild heat response that elevates core body temperature and increases calorie expenditure. It also supports healthy digestion and nutrient absorption.
Research: Studies in the British Journal of Nutrition have demonstrated that capsaicin supplementation increases energy expenditure and fat oxidation in both lean and overweight individuals.
6. Apple Cider Vinegar Powder — 200 mg
What It Is
Apple cider vinegar (ACV) powder is a dehydrated form of fermented apple juice, providing the active compound acetic acid in a convenient capsule format without the harsh taste of liquid ACV.
How it works: Acetic acid slows gastric emptying and the digestion of starches, resulting in a more gradual rise in blood sugar after meals. It also supports healthy gut bacteria diversity and promotes a feeling of fullness.
Research: A study in the European Journal of Clinical Nutrition found that acetic acid supplementation reduced post-meal blood sugar responses by up to 31% when consumed with a starch-rich meal.
What's NOT in CitrusBurn
