So what makes the UNALTERED Weight Loss Stack different from all the others?

That’s a great question. If you’re here, chances are you’ve tried other weight loss supplements that didn’t work.

Are we right? This is because most supplement companies use the cheapest and most ineffective ingredients in their products in order to lower their manufacturing costs! Of course, they won’t tell you this, but you’ll know when you use the product and you don’t see any of the results that company promised.

We don’t believe in sacrificing quality for cost. That’s why we use only the most effective weight loss ingredients at their most effective, scientifically-proven dosages.

Here is a complete list of all the ingredients we use, along with the science to back them up! So what are you waiting for?! We did all the research for you. Now it’s time to conquer your personal weight loss goals with peace of mind, knowing that you are using the most effective thermogenic fat burner supplement on the market!

Ingredients Driven By Results

Tap on each ingredient to learn more.

5-Hydroxytryptophan - 750 MG

Known as the “happy” chemical, 5-HTP is the precursor to serotonin. Although 5-HTP is widely marketed as a mood enhancer, studies show that it is more effective as a weight loss supplement, helping to suppress appetite and reduce calorie-consumption


Subjects who took 750mg of 5-HTP daily, for 2 weeks, reduced their calorie intake (mainly from carbohydrates), which resulted in significant weight loss.

Subjects who took 5-HTP for a period of 12 weeks lost more weight than the placebo group and reduce their overall food intake.

Supplementation of 5-HTP for over 5 weeks resulted in a 38% reduction in calorie-intake.


Forskolin, the main active ingredient of Coleus Forskohlii, is a natural plant extract that has been shown to reduce inflammation and induce weight loss, while promoting lean muscle gain.


Subjects who took 500mg of Coleus Forskohlii daily lost an average of 10lbs of weight, and gained an average of 8lbs of lean muscle.

Subjects who supplemented with 500mg of Coleus Forskohlii for 12 weeks was able to prevent fat gain, relative to placebo.

Irvingia gabonesis - 300 MG

Irvingia Gabonensis is a supplement derived from the seeds of the African Mango plant, shown to induce weight loss.


150mg of IG prior to meals was associated with reduced calorie intake, which in-turn, induced weight loss.

Supplementation of IG for 2-4 weeks is associated with weight loss.


Yohimbe is a natural bark extract that works by increasing adrenaline levels in the body, as well as inhibiting a regulatory process that normally suppresses fat-burning.


Subjects who took Yohimbe daily for 21 days lost an average of 2.2% body fat.


A molecule derived from brown seaweed, Fucoxanthin has been shown to aid in fat-burning.


Subjects who consumed Fucoxanthin experienced an increase in their metabolic rate.

CLA (Conjugated Linoleic Acid) - 3000 MG

CLA is a natural plant extract that has been shown, through various clinical studies, to promote visceral fat loss (AKA belly fat loss) through its unique effect on our molecular signaling receptor family known as PPAR, which is related to fat burning.

    Worked amazing.

  2. Dom H

    This product is great! Ideally I like using it during fasted cardio (on a empty stomach) which helps kick-start the weight loss process. Combined with the CLA also offered by Unaltered, together these products can help you quickly and safely reach your fitness goals. Already I have noticed feeling a bit “lighter” after all the excess holiday calories consumed over the last few days. Be sure to drink plenty of water too (you should shoot for at least a gallon a day anyways) for best results. :)

    I’ve been taking the Unaltered Fat Burner for the month of January & I was surprised with the results I saw. I am a pretty active person to begin with, but I had been struggling leaning out the way I wanted to the last couple of months. Since taking the Unaltered Fat Burner along with my exercise & generally healthy diet, I have 100% felt leaner–in my stomach area & definitely in my arms, which I was very excited to notice! I’ve been taking it along side the Unaltered CLA’s & I think together I’ve seen the best results from a pill(s) than I ever have in the past. 10/10 recommend trying this one out!!

    I loved this product and pairing it with the CLA Pills from UNALTERED worked wonderfully! Over the past 4 weeks I saw a decrease in inches around my waist and my energy was through the roof! Taking these paired together kept my focus up and energy high even with working long days and training. I found that it also helped curb my hunger when I had down time. Pairing these two products and incorporating a caloric deficit with also adding minimal of 1 day of cardio to my current program really helped me tone up and tighten my midsection and legs! High Recommend!

  5. Daniel Ramirez

    Days after starting to take this I felt much more energized in the morning, usually takes me hours to get to feeling 100% but these definitely helped speed up that process. Not only that but I feel like they have definitely suppressed my appetite. I am having much fewer urges to eat. Purchased this along with the Unaltered CLA and have noticed a reduction in belly fat since last week. Can’t wait to see what the two will do for me long term!!

  6. Gerri

    I am super impressed with this product! Taking this and the CLA pills by Unaltered I have lost significant weight in a short amount of time. I do not have stomach fat or bad bloating anymore because of this product. Love it!

  7. Kayla

    Amazing product! Made me sweat and gave me amazing energy to push through my workouts! Clean cut energy without the jitters or tingling sensation. Definitely worth the buy!

  8. prodbydoza

    I purchased this fat burner along with the CLA as recommended by Unaltered themselves. After using it for a few days, I can safely say their recommendation is accurate, and I’m SO GLAD. I’m starting to see more definition, so I’m very excited to keep my routine going.

  9. Mauro

    This is a great fat burner. It definitely seems to do exactly what it says it does. I get a nice, even energy flow from it without being jittery. It also seems to work great when used in conjunction with UNALTERED Protein and CLA.

  10. Courtney

    These CLAs are wonderful. Definitely help with slimming the belly and when you use this with the Unaltered Fat Burner too, you will notice such a huge difference! I live by this company’s products and they really do cherish their customers. I’ve surpassed my fitness goals thanks to their products. Repeat customer for life!

  11. musky

    I am a fan of CLA in general bc it is evidence based to support muscle mass and I used this in conjunction with the Unaltered Fat burner and it was great. I love to lift weights but I also teach a lot of cardio classes as an instructor so I find it important to have a CLA supplement like this to help conserve muscle mass bc exercising general is a catabolic process . When the goal is to lose FAT (not just overall weight) while conserving muscle, this is a great supplement.

    As a natural figure competitor I’m always looking for natural, high quality supplements. I was very excited to find a company that was founded by natural athletes that also care about natural, high quality supplements. Currently I’m in the middle of offseason and trying to build as much lean muscle as possible, do as little cardio, eat all the carbs and keep body fat stable. I noticed an increase in energy and a decrease in appetite, which is specifically helpful when I do have my lower carb days when I’m not training (twice a week). After taking these products for a month, I had check ins with my coach. My body fat has remained steady, my hips are up while my waist is down, (we’ve been hitting legs HARD). I also was able to put on a 1/4 inch on my biceps and 3/4 inch on my lat spread. These products not only help with fat loss, they help with body decomposition! Definitely going to be reordering and implementing these into my diet when I start cutting for my spring show!

    Took the first bottle and it worked great as described. Had a trip to Florida and wanted to reduce body fat before the trip. Within two weeks I started to notice the definition in my bottom two abs (the hardest to show). Did not feel uncomfortable at all while taking the product. I did take CLA along with 100% Unaltered Fat Burner and was extremely satisfied with the results. I was so satisfied that I did order another bottle. Easy to take, three pills on an empty stomach first thing in the morning, then I took another three in the afternoon (on an empty stomach as well). I do exercise four times a week and I do eat clean (no added sugars and I minimized carbs while on the product, just because I was in a time crunch to look better for the beach). I really recommend the product and CLA at the same time. I know there are no miracle pills, but this is a great SUPPLEMENT as described. You still have to do your part and eat clean/workout for results to show. I doubt this would just make fat disappear without you doing your part. It did help me achieve my goals in the time period I had, and I will still use the product to get to where I would like my body to be. Also, the bottle I received shows on the cap, if you write a review after taking the product for 15 days they will send you another bottle for free!! If I did not see the results I saw, I would not have written the review I just did.

    I am seriously so impressed with the appetite suppressant nothing has seemed to work for me but this products definitely does! I would highly recommend trying it if you cant seem to stop snacking. It doesn’t make you feel weird or jittery either. Very impressed!
