About the Product
Life Pro Nutrition's Evidenced Burner is the brand's base fat burner, belonging to a family of thermogenic products that also includes Evidenced Wild Burner (version with more concentrated doses per capsule) and Wild Ripped (more complete version with added phenylcapsaicin). The formula is built around 3 synergistic ingredients with the strongest scientific evidence for fat oxidation: bitter orange dry extract (source of p-synephrine), green tea dry extract (source of EGCG and polyphenols), and anhydrous caffeine. Per daily dose of 4 capsules (Evidenced Burner 120 caps): 80 mg of p-synephrine + 400 mg of EGCG + 300 mg of caffeine. Per dose of 1 capsule (Evidenced Wild Burner 90 caps): 30 mg of p-synephrine + 167 mg of EGCG + 133 mg of caffeine. Vegan. Gluten-free ingredients.
Benefits
The thermogenic trilogy with the strongest evidence base: caffeine + EGCG + p-synephrine in documented synergistic doses:
The formulation principle of Evidenced Burner is the rigorous selection of the 3 compounds with the greatest support from meta-analyses and systematic reviews for fat oxidation and increased energy expenditure, as opposed to formulas with 10 to 20 ingredients where each is present in sub-therapeutic doses (the "proprietary blend" problem of many fat burners). The academic background and the product name ("Evidenced") precisely reflect this philosophy: no ingredients without solid clinical evidence are included, and the 3 chosen ingredients are dosed in the quantities documented in studies. The review by Jeukendrup & Randell (2011), published in Obesity Reviews, specifically identified caffeine, EGCG, and synephrine as the 3 thermogenic compounds with the best evidence/safety ratio available on the supplement market.
Anhydrous caffeine: the most studied thermogenic and the starting point of the trilogy:
Anhydrous caffeine is the main thermogenic and lipolytic agent in the formula. As described in Life Pro's pre-workout products, caffeine acts as an antagonist of adenosine receptors (A1 and A2A), with multiple effects relevant to fat oxidation. First, it increases sympathetic nervous system activity (via blockade of presynaptic adenosine receptors that inhibit noradrenaline release), resulting in increased adrenergic tone that stimulates lipolysis (fatty acid release from adipose tissue) via β-adrenergic receptors in adipocytes. Second, it inhibits phosphodiesterase (PDE), the enzyme that degrades intracellular cAMP: the increase in cAMP in adipocytes activates hormone-sensitive lipase (HSL), which hydrolyses stored triglycerides into free fatty acids available for oxidation. Third, it increases basal energy expenditure by stimulating the central and peripheral nervous system (caffeine increases basal metabolism by 3 to 11% at rest, depending on the dose and individual sensitivity). The meta-analysis by Tabrizi et al. (2019) analyzed 13 randomized clinical trials on caffeine and fat loss, documenting that caffeine was associated with greater weight loss, body fat, and BMI compared to placebo.
Green tea extract and EGCG (epigallocatechin-3-gallate): the polyphenol that enhances and prolongs the lipolytic effect of caffeine:
Green tea extract (Camellia sinensis) is rich in catechins (flavonoid polyphenols), with epigallocatechin-3-gallate (EGCG) being the most abundant and potent (representing 50 to 60% of the total catechins in green tea). EGCG enhances and prolongs the thermogenic effect of caffeine through a direct synergistic mechanism: EGCG inhibits catechol-O-methyltransferase (COMT), the enzyme responsible for the degradation of noradrenaline (NA) in peripheral tissues. Noradrenaline is the main adrenergic neurotransmitter that activates β-adrenergic receptors in adipocytes (stimulating lipolysis) and in thermogenic tissues such as brown adipose tissue (stimulating uncoupled thermogenesis). By inhibiting COMT, EGCG increases the half-lives of noradrenaline in target tissues, prolonging and amplifying its lipolytic and thermogenic action. This mechanism is directly synergistic with caffeine (which increases noradrenaline release) and with p-synephrine (which also activates adrenergic receptors). The meta-analysis by Hursel et al. (2009), published in the International Journal of Obesity with data from 11 studies, documented that the combination of green tea catechins with caffeine increased energy expenditure by 4.6% and fat oxidation by 16% compared to placebo, with a greater effect than caffeine alone.
P-synephrine (bitter orange extract, Citrus aurantium, 6% synephrine): the legal and safer substitute for ephedrine:
P-synephrine (synephrine-para, or p-synephrine) is a natural sympathomimetic protoalkaloid present in the fruit peel of Citrus aurantium (bitter orange, zhi shi) and other Citrus species. P-synephrine is structurally similar to ephedrine (which was banned by the FDA and WADA due to cardiovascular risk) but with a much more favourable safety profile: unlike ephedrine (which activates both vasoconstrictive α-adrenergic receptors and thermogenic β-adrenergic receptors), p-synephrine has preferential selectivity for β3-adrenergic receptors (expressed mainly in adipose tissue, with the function of stimulating lipolysis and thermogenesis) and much less activity at α-1, α-2, and β-1 receptors (which would mediate the adverse cardiovascular effects of ephedrine). This selectivity for β3-adrenergic receptors explains why p-synephrine has documented lipolytic and thermogenic effects with minimal impact on heart rate and blood pressure at supplement doses. The clinical trial by Stohs et al. (2011) documented that 50 mg of p-synephrine increased resting metabolic expenditure by 65 kcal/hour without significant changes in heart rate or blood pressure. The dose of 80 mg/day in Evidenced Burner (4 capsules) is higher than the dose studied in this trial, confirming a functional dose and in line with the maximum limit recommended by the EFSA for supplement use (up to 100 mg/day for general use).
Synergism of the 3 molecules: a combined effect superior to the sum of the parts:
The caffeine + EGCG + p-synephrine trilogy has documented synergism that goes beyond the addition of individual effects. Caffeine inhibits phosphodiesterase and blocks adenosine (increasing cAMP and noradrenaline), EGCG inhibits COMT (prolonging noradrenaline action), and p-synephrine directly activates β3-adrenergic receptors in adipocytes (stimulating lipolysis independently of circulating noradrenaline). The three compounds act at different points of the same adrenergic/lipolysis signaling cascade, creating a multiple amplification of the lipolytic signal. The review by Stohs & Badmaev (2016) in Phytotherapy Research specifically analyzed the combination of p-synephrine + caffeine + green tea catechins, documenting a combined thermogenic effect superior to combinations of only 2 ingredients.
Uses
Recommended dose (Evidenced Burner 120 caps): 4 capsules/day (80 mg p-synephrine + 400 mg EGCG + 300 mg total caffeine). Training days: 2 capsules 40 to 60 minutes before training + 2 capsules between meals throughout the day. Non-training days: 4 capsules distributed among main meals. Start with 2 capsules/day to assess caffeine tolerance before progressing to the full dose.
Recommended dose (Evidenced Wild Burner 90 caps): Start with 1 capsule/day (133 mg caffeine + 167 mg EGCG + 30 mg p-synephrine), 40 minutes before training. Can progress to 2 capsules/day if well tolerated. Avoid consumption after 5 PM to avoid disrupting sleep. Do not exceed 3 months of continuous use; take a 2 to 4-week break between cycles.
