Solid glucomannan dose, big tyrosine hit, moderate stims for real control.
Raw Nutrition Burn Thermogenic Powder is a straight-up, moderate-stim fat burner that hits three big areas: curbs your appetite, sharpens your focus when calories are low, and gives a solid thermogenic boost without the shaky overload. That's key because most burners just pile on stims and skimp on what keeps a diet going strong. Burn does it smarter: fiber for feeling full, aminos and theanine for brain support, and a mix of caffeine, green coffee, GBB, and yohimbine for energy and fat mobilization.
The star here is 3.5g glucomannan at 95% from konjac root— that's a solid dose in the 2-4g range from studies. Glucomannan is a thick soluble fiber that soaks up water and turns into a gel in your gut, slowing things down so you feel fuller longer. In real life, that means less hunger hits and better control between meals on a tight diet. Mix it with lots of water, and Burn gives it the space to really work.
You've got 3g acetyl-L-carnitine, which beats the usual 1.5-2g doses out there—one of the best in its class. It helps move fatty acids into your cells' power plants for burning, but the cool part is it crosses into your brain too. So you get fat support plus a clearer, more dialed-in vibe during those tough dieting days when energy tanks.
L-tyrosine at 3g is a heavy hitter. Tyrosine is what your body uses to make dopamine, norepinephrine, and epinephrine—super useful when you're stressed, short on sleep, training hard, or cutting calories. Studies show it's best for keeping your brain sharp under pressure, not just ramping you up from nothing.
RAW Burn Thermo by Raw Nutrition contains 25mg Vitamin B6, a effective dose for training performance and pump.
Key Highlights
- 3,500mg Glucomannan 95% — a real-deal dose for hunger control, not just a tiny add-on. It soaks up water and gels up in your gut, slowing digestion so you feel full and dieting doesn't suck as much.
- 3,000mg Acetyl-L-Carnitine — beats the usual 1.5-2g doses and makes this more than a basic stim powder. It moves fatty acids to your cells for energy and hits the brain too, giving you a sharper, more useful feel.
- 3,000mg L-Tyrosine — one of the biggest doses for focus in a fat burner. It helps make dopamine and norepinephrine, which keeps your head in the game when stress, low food, or tough workouts try to drag you down.
- 2,000mg Inositol NF — a good amount for metabolism and brain support that most burners skip. It's at the low end of effective doses and adds extra help for dieting under pressure.
- 150mg Caffeine from Green Tea — enough to wake you up and push your workouts without going overboard and messing with sleep. This is built moderate on purpose, not a caffeine bomb.
- 150mg L-Theanine matched 1:1 with caffeine — smart move in the mix. Studies show they team up for focused energy, so you get a smooth lift without the usual caffeine shakes.
- 2.5mg Yohimbine HCl — a small but effective dose that ramps up the thermogenic feel, especially fasted. It makes Burn punch harder than just 150mg caffeine alone.
- 500mg Green Coffee Extract at 50% chlorogenic acid — here to back the fat-loss angle without more caffeine. Chlorogenic acids help with metabolism and flesh out the burner side beyond just stims.

Who Is This For?
- Lifters on a cut dealing with hunger, cravings, and weak workout drive more than the lifts themselves. 3.5g glucomannan helps fill you up, 3g tyrosine and 150mg caffeine keep sessions strong on low food.
- Morning cardio crew wanting a burner beyond caffeine dumps. Burn mixes moderate stims with yohimbine HCl, green coffee extract, and GBB—great for fasted or low-fuel slots where energy lags.
- Folks chasing body comp who need real appetite help, not just grit. Clinically dosed glucomannan tackles fullness head-on, not faking it with extra stims.
- Busy workers dropping fat while handling long days and evening gym time. Caffeine-theanine-tyrosine keeps you alert and steady without the wild ride that kills focus or crashes you.
- Mid-level supplement users after a clear-label powder over mystery capsules. Full disclosure on every dose lets you check against real ranges, no guesses.
- Athletes okay with moderate stims but skipping 300mg+ caffeine bombs. Burn's 150mg feels right with theanine, yohimbine, green coffee, and ALCAR layering in.
How to Use
If stims, yohimbine, or fiber hit you hard, start with half a scoop to test. Full scoop 20-30 minutes before training, cardio, or hunger peaks. Mix in 12-16oz cold water and chug quick—glucomannan thickens fast, so more water makes it easier. Empty stomach amps the stims and yohimbine; with food, it's softer but still fills you up. Don't stack blindly with other burners or high-stim pres—add up your caffeine, yohimbine HCl 2.5mg, and GBB first. Goes well with creatine, protein, and hydration since it skips those. Daily during fat loss is fine, but mix in low-stim days for tolerance and sleep. Store sealed, cool, and dry—fiber powders clump easy with moisture.
What to Expect
Minutes 0-10: mix with enough water 'cause glucomannan thickens up. You won't feel a rush right away, but it starts working, and fullness might kick in early before food or cardio. Minutes 10-20: caffeine picks up, feeling alert with theanine smoothing it; some get a warm vibe from GBB and stims. Minutes 20-40: peak time—focus sharpens, hunger dials back, workouts easier to start. Minutes 40-90: energy stays even, but yohimbine might stand out if you're sensitive. Days 1-7: hunger control and workout readiness shine. Weeks 2-4: real win is sticking to your deficit better, with less fatigue and skipped days messing things up.

Frequently Asked Questions
How much caffeine is in Raw Nutrition Burn Thermogenic Powder?
Each 1-scoop serving provides 150mg caffeine sourced from green tea. That is a moderate dose by thermogenic standards, but the formula can feel stronger than 150mg alone because it also includes 2.5mg yohimbine HCl and 40mg GBB.
Is the glucomannan dose in Burn actually meaningful?
Yes. Burn includes 3.5g glucomannan standardized to 95%, which sits well within the 2-4g clinical range used in research on satiety and metabolic support. This is one of the most credible parts of the formula and a real differentiator versus stimulant-only fat burners.
What does the 3g acetyl-L-carnitine do in this formula?
Acetyl-L-carnitine supports transport of fatty acids into mitochondria for energy production, but its value here is not limited to fat metabolism. Because ALCAR crosses the blood-brain barrier, it also contributes to the more focused, mentally engaged feel of the product during a calorie deficit.
Can I take Burn fasted before cardio?
Yes, many users do, and that is one of the most common use cases for this formula. Just understand that yohimbine HCl often feels stronger in fasted conditions, so stimulant-sensitive users should start with 1/2 scoop first.
Why is L-theanine included in a fat burner?
Burn uses 150mg L-theanine to pair with its 150mg caffeine dose. Theanine helps smooth the stimulation profile, promoting a more focused and less jittery form of alertness than caffeine alone.
Will this product help with appetite or is it mainly energy?
It is both, but the appetite-control side is unusually strong for this category because of the 3.5g glucomannan dose. That ingredient is there specifically to increase fullness, while the caffeine, tyrosine, and theanine side helps you stay productive and train well while eating less.
Can I stack Burn with a pre-workout?
You can, but you need to account for the full stimulant load. Burn already includes 150mg caffeine, 2.5mg yohimbine HCl, and GBB, so stacking it with another stimulant-heavy pre-workout can push the experience into uncomfortable territory quickly.
Does Burn use proprietary blends?
No. The formula is fully transparent, with every active ingredient and dose disclosed on the label. That allows you to compare each ingredient against research-backed dose ranges instead of guessing what is buried in a blend.
What is BioPerine® doing in this formula?
BioPerine® is Sabinsa’s branded black pepper extract standardized for piperine, included here at 5mg. It is used to support bioavailability by influencing metabolic enzymes and intestinal transport, helping improve absorption of co-administered compounds.
Is Burn a good first fat burner for beginners?
Not usually as a first-ever thermogenic, mainly because it includes yohimbine HCl and a large 3.5g fiber dose. It is better suited to users who already know how they respond to stimulants and are comfortable managing water intake, timing, and tolerance.
