This unique 2-in-1 product combines the muscle-building potential of pure Whey Protein Isolates with fat-burning support from L-Carnitine.* We’ve also add Green Coffee Extract and Lepticore. This simulant-free powder mixes easily into cold water to provide the delicious milkshake taste you’ve come to love from BSN®. It’s the perfect 120 calorie shake for active adults who are determined to build lean mass while cutting body fat.*

2-In-1 Support for Your Fit Physique

If you’re into regular exercise and watch what you eat, BSN®’s ISOBURN® is a great fit for your healthy, active lifestyle. Each serving delivers 20 grams of Whey Protein Isolate to help support muscle and recovery.* This quality protein powder will help supplement the daily amount of protein required by your body and help you to reap the benefits from every training session. ISOBURN®’s ingredients also help support fat-burning with the inclusion of L-Carnitine.* Because it’s stimulant-free, you can mix up a great tasting ISOBURN® shake any time of day.

The Science behind the Burn

ISOBURN® delivers 250 mg of L-Carnitine per serving. Carnitine may help fat-burning by supporting fat oxidation for energy production.* ISOBURN® also contains 300 mg of LeptiCore per serving, which is a multifunctional complex consisting of blue-green algae, pomegranate, fatty acids, and polysaccharides. Lastly, ISOBURN® delivers 300mg of Green Coffee Extract per serving. Green Coffee Extract comes from Green Coffee Beans, or coffee beans that have yet to be roasted.

BSN Supplementation

At BSN®, we have designed our products to complement one another. When used together, they can help enhance the overall benefits of your supplementation and workout regimen.*

I really enjoyed using this and felt it helped with cutting. I tried the vanilla and loved the flavour. Honestly, I think every product BSN has is truly great, thanks!

I've had this and used it for about a week now and I have noticed that I sweat SO much more after I drink this! I have done the same workouts and never sweat that much. The fat burners are really working in my system. The taste, however, isn't the greatest. I LOVE BSN products so this was a bit of a surprise but it's not that big of a deal because I love the way it works! Would DEFINITELY buy again!

Wow where do I start.... This is my FIRST time every using this product. Isoburn is very intense when it comes to my body and how I react to supplements (could be different for others). I work out early in the morning. I wake up at 2:40am and get to the gym at 3am. As soon as I wake up I take a scoop of this in some fat free milk with half a banana and then head out to the gym. (for obvious reasons I do this so that I don't burn muscle by working out on an empty stomach) I can honestly say this makes me very focused and I can tell a great difference in how much I sweat during my warmup/throughout my entire workout routines. It does not make me feel bloated. It doesn't upset my stomach and most of all the flavor is great! The flavor is very light, not insanely sweet as some products try to do, and it doesn't have a fake vanilla flavor aftertaste. I pair this along with my BSN pre-workout (Great stuff as well). I will NEVER run out of this from now on. I wish I would have gotten it sooner.

I started using the product a week ago, been great so far. Great taste and definitely a good idea to use it after your workouts.

My goal is to cut fat and build lean muscle. ISOBURN gives me the energy and focus I need to get through my evening workouts. It also satisfies my cravings in between meals during the day. I've been using this for two weeks now, along with a 1,200 calorie diet and working out four times a week, and I have seen great results. I feel stronger, my clothes already fit better and I have lost 5 lbs. so far. I gave this product a 9 because of the flavors. Vanilla Ice Cream is the best because it tastes good on its own with water or mixed with any type of fruit or smoothie, without tasting too sweet. Strawberry Milkshake is good, but a little to sweet for me. Chocolate Milkshake is alright, but it tastes kind of chalky on it's own. Syntha-6 has a lot more flavor options, but it doesn't have the fat burning ingredients that ISOBURN has. I hope they add more flavors because this is a great product.

Excellent taste. You can kind of taste the fat burners a little but it still tastes like good old Syntha 6. Weather or not it actually burns fat...... I didn't see any results. It still is a quality protein though

This protein powder was a huge disappointment. It did not mix smoothly and did not faste good at all. I did not even get the chocolate flavor.

I was already a fan of BSN protein powders because of the quality and the fact that their flavors are on point. A couple of weeks after I had a baby I started using the IsoBurn and I am now 3.5 months post partum and 5 pounds from my pre-pregnancy weight. Of course, it wasn't this product alone, but it has been a good boost of energy and hunger satisfaction to keep me going. If you get the right water to powder ratio it's delicious and smooth. It's also good blended with almond milk and a banana. You can drink it anytime of the day whether it's a quick and easy meal replacement or pre/post workout drink. Don't think that you can simply use this daily and weight will fall off, but it's an excellent supplement to a healthy, balanced diet and workout routine.

I love this protein powder. I have the chocolate flavor as a stand alone shake every morning at work. On the weekends I mix the vanilla with fruit and yogurt for awesome smoothies.

I mix vanilla with water, ice, and a banana and/or mixed fruit using the NutriBullet. The taste is incredible. I usually am not a big fan of vanilla flavors - Phase 8 being the only other vanilla that doesn't have a watered down taste - but this one is the real deal. I am indifferent to Syntha-6 but Iso is excellent.

This one was simply surprising! I bought it more for weekend trips when I don't have good food available and need that protein in me to stay full and sustained. It is surprisingly filling, tastes awesome and is convenient to carry around in the little sized jar.
