CARBOTEIN® is a scientifically advanced carbohydrate formula for glycogen loading that enables rapid energy use along with post-workout recovery. CARBOTEIN uniquely combines 6 fast-acting, specialty carbohydrates with branched chain amino acids plus multiple electrolytes and citric acid cycle intermediates. Drink before, during, and/or after training to support maximum muscular work output and endurance, glycogen replenishment, loading, and muscle building (anabolism).*

The Carbotein Advantages:

  • Maize Maltodextrin: Promotes low-osmolality conditions for more efficient absorption
  • Rice Maltodextrin: Disperses rapidly in solution
  • Potato Maltodextrin: Like Maize Malto, this ingredient promotes low-osmolality conditions
  • Fructose: Promotes replenishment glycogen stores and improves flavor
  • Fibersol®: Ultra-low glycemic index dietary fiber
  • Oligodextrin: Low glycemic energy source

I have been impressed with Carbotein and how it has enhanced my workouts over the past couple of weeks. I am always wiping away sweat at a crazy frequency, all the while feeling like I have plenty of strength to push through, even with high volume workouts. The Orange flavor is just fine - I wouldn't say I loved it with a passion, but it was good - straight up orange. It was NOT weird/chemical tasting, which is good! I have been having strong pumps during, and even after my lifts lately. That wasn't always the case before I started implementing Carbotein. Great stuff!

I'm loving Carbotein so far! It really is the perfect carb drink, and for me personally, is perfect to use during all my workouts. Even though it is a carb drink, its not heavy at all, and it doesn't make your stomach feel any different during or after drinking it. No stomach problems here like with other similar products that people might have. The ingredient list is excellent, having 6 speciality carbs, and is low in sugars and fat overall. The mixability is great, one scoop mixed with a regular water bottle works great for me. The taste is amazing! The orange flavor reminds me exactly of orange soda! This product really keeps me going during my workouts, and I can definitely notice more energy to keep pushing through the gym. Overall, Carbotein is a great product and I would definitely recommend!

I've had other carb shakes, such as Karbolyn and Carb-slam. Carb-slam always left me bloated and gassy. During my recent gaining stage, I needed an intra carb shake, and one that would sit well with me. I picked up a container of Carbotein and it became my new favorite to use while training! It left my muscle bellies full, without any discomfort!

My experience with carbotein from GAT was a great one. I had never used a carb supplement during my workouts before this, wow what I was missing, It always seems that my workouts tend to push two hours and getting through the last half is always a bear. Enter Carbotein! My stamina and recovery between sets took off. With a blend of different carbs to serve slightly different functions, this is the complete carb, never mind a little extra BCAAs. The flavor was spot on, good solid orange flavor but not the fake kool aid type orange. It also mixed very well, didn't take a lot of work, a couple swirls and a little shake .. .done. Carbotein orange also stacks great, try it with your Nitraflex Pina Colada pre or with Vanilla Supertein post!

Another great addition to the GAT lineup. First the taste reminds me of Nestlé's Orange Creamisicle. It's very tasty. I've used this mostly as my intra workout and it helps give me the extra burst I need after a long intense workout. It mixes up nicely though at times there were a little foam but those goes away quickly. If you stack this with Nitraflex and Supertein you'll have yourself a stack of champion.

Flavor: Grape 8/10: I really enjoyed the flavor, taste most like store brand grape juice. It definitely tastes much better in cold water. Mixability: 10/10: I thought that it mixed OK. It takes a while to have it completely dissolve though with small amount of foam on top. Recovery: 8.5/10: I definitely felt like I recovered better noticed more i wasn't as sore. Performance/Endurance: 8.5/10: I seemed to do better with my workouts. More PR's were coming up. Endurance and stamina was a factor with this to! Was able to push myself harder during leg workouts then i have before. PUMP:9/10 This was what i noticed the most getting huge pumps on back/shoulder day making me want to re hit the gym just to relive the experience!

If you want a healthy supplement for carbs, here is the one. The taste is excellent though it can leave a vitamin like taste but that's more power to it. Best time to take it is post training but it can be taken also pre or during. If you're looking for a BCAA product as well. during this phase you wont have to look anywhere else as this comes with 1300 mg of active BCAA's. I was looking for a strength increase and overall this has helped. Great product rated high in the store!

Thanks to Greg and the folks at GAT, I was able to give this a try for over a month. I took Carbotein as an Intraworkout drink and it was perfect. This is one of those supplements you can truly test if it works or not. The days I did not take it, I felt like I had to push myself even more, yet the days I did take it, I felt I could do more...had much more endurance. I previously would do the Poptart preworkout thing, but the sugar crash sometimes got me. Now, I am adding Carbotein to my stack as an intraworkout to keep me going, Would highly recommend this. The grape flavor is outstanding! Please see my log for more details! Also, for even more added benefits, think about mixing in with coconut water and the benefits are tremendous

WHAT A FREAKING PUMP!!!! I'm using this as a carb loader for during and post workout as I'm cutting and taking in no other carbs and holy **** do i get the best pumps ever!!!.

Carbotein is an awesome post carbohydrate post workout, I love all GAT products and this just tops the list! The maize maltodextrin absorbs really well for me and keeps the muscles hydrated and fueled after a workout. The 6 specialty Carbohydrates with BCAA's and electrolytes are perfect for my glycogen loading after a workout, definitely recommend! -Brad brad.bastian7 @gmail

This is the latest intra workout Carbohydrate supplement on the market, and GAT has done a great job with this product. This supplement really makes the difference in my training, every day. The maltodextrin mix is the high quality carbohydrate that allows me to get the energy needed before my workout. 10 minutes before and during my workout will usually do it. It is also the best carbohydrate supplements for glycocen loading, after my workout. I can really tell the difference between the carbohydrates from Carbotein and other brands on the market. But without question, this is the best I have used for a long time and I will continue to use it for as long as I can. This is suitable for both women and men, and helps with keeping the muscles full during your workout. As I wrote before, it is even greater for recovery in terms of glycogen storage in the muscles. Once again, great job GAT and thank's for bringing this to the market. Best carbohydrate product out there, well worth trying if you are serious about your training folks!

Carbotein is the latest carbohydrate intra workout on the market and it is top of the line just like the rest of their products. Their maize maltodextrin makes for easy absorption which keeps you from feeling full or bloated during your workout. This product is awesome to keep your muscles flooded with nutrients, referring to the glycogen replenishment which is crucial. If you're looking for skin splitting pumps, this is the product to use. Safe for both men and women to use. I love it for low carb days because this is one of my carb sources so it's awesome to start sipping on about 10 minutes before my lift to get it into my system and during my workout so I don't feel flat.

Directions For Carbotein:

Prepare each individual serving used by mixing it with 6-8 oz (200-250 ml) of cold water, with ice cubes, if desired, in a shaker bottle, water bottle, or blender. Add 3-4 oz. (100-125 ml) of water for each additional serving used.


Fuel yourself to spare muscle glycogen (storage form of glucose) and prevent early fatigue, drink 1 serving 15-30 minutes pre-training.

During Training:

To support glucose levels and sustain muscular output, drink 1/2 serving every 30 minutes. Endurance athletes competing in prolonged exercise should sip 1 serving in 8-10 oz. water for more energy and hydration.


For workouts lasting up to 90 minutes, consume 1/2-1 serving within 40 minutes post-training. Follow this with at least 20g of high-quality protein. For workouts lasting longer than 90 minutes, consume 1 serving post-training and another 1 serving 60 minutes later.
