Raw Nutrition | x CBUM Fat Burner | 60 Capsules

Raw x CBUM Essential Fat Burner is a transparent, stimulant-based thermogenic built around a very specific strategy: combine moderate caffeine with multiple pathways that increase thermogenic drive rather than relying on caffeine alone. That matters, because the fat burner category is crowded with formulas that feel intense for 30 minutes but are really just overdosed stimulants. This one takes a more layered approach: central nervous system stimulation from caffeine, smoother sustained support from theobromine, thermogenic signaling from grains of paradise and capsicum, and a carnitine-pathway ingredient in GBB HCl.

The energy backbone is 200mg total caffeine: 150mg caffeine anhydrous plus 50mg delivered from 239mg guarana extract standardized to 22% caffeine. Caffeine works primarily through adenosine receptor antagonism, increasing alertness, reducing perceived exertion, and helping maintain output when calories are lower. At 200mg total, this lands in the moderate-stim range—enough for a clear uptick in energy and appetite control for many users, without automatically pushing into the aggressive territory of high-stim burners.

Green Tea Leaf Extract at 250mg adds a classic fat-loss support ingredient that is often included for its catechin content, especially EGCG, which is studied for supporting energy expenditure and fat oxidation. Exact standardization is not listed, so the quality of that effect depends on extract profile, but green tea remains one of the better-known evidence-backed inclusions in this category.

Theobromine at 100mg is a smart supporting stimulant. It is milder than caffeine, but often produces a smoother, longer energy feel with less abrupt edge. Emerging evidence also points to cardiometabolic benefits, though that literature is not yet as robust or performance-specific as caffeine research. Mechanistically, it complements caffeine well: caffeine hits faster and harder; theobromine tends to feel steadier and can help round out the experience.

Gamma-Butyrobetaine HCl at 50mg is included for thermogenic support through the carnitine pathway. GBB is a precursor involved in endogenous carnitine synthesis and is often used in burners because users commonly report a distinct increase in body heat and sweat response. This is not a stimulant in the same sense as caffeine; it is there to make the thermogenic side of the formula more tangible.

CaloriBurn GP® Grains of Paradise at 30mg is one of the most compelling trademarked inclusions here. Grains of paradise has human data supporting activation of brown adipose tissue and increased energy expenditure. In a category full of vague “metabolism boosters,” this is one of the better premium ingredients because it targets thermogenesis through a distinct mechanism rather than simply adding more stimulants.

Capsimax® Cayenne at 25mg adds another clinically relevant thermogenic pathway. Capsinoids and capsaicinoid-related compounds are studied for promoting thermogenesis, calorie burning, and in some users, appetite support. Capsimax® is designed to improve tolerability compared with raw cayenne by controlling delivery.

BioPerine® at 5mg rounds out the formula by supporting absorption and utilization. It is a common but useful inclusion in capsule formulas where maximizing uptake matters.

As a system, this formula stacks three thermogenic levers—caffeine-driven stimulation, BAT-related support from CaloriBurn GP®, and capsicum-driven heat production—then smooths the experience with theobromine and supports ingredient uptake with BioPerine®. Just as important, it is fully disclosed with no proprietary blend, which is a major trust advantage in a category that often hides weak dosing. Day 1, expect a noticeable lift in energy, warmth, and sweat response. Over 2-4 weeks of consistent use alongside a calorie deficit and training, the real benefit is better adherence: more productive sessions, less diet fatigue, and a more effective thermogenic routine.
