## Features

- FAST-ACTING FUEL: Karbolyn is a clinically studied (with peer-reviewed, published research) carbohydrate supplement powder sourced from potato, rice, and corn. It’s specifically designed for elite athletes looking for a fast, safe, and effective way to quickly and easily load their muscles with lasting energy and promote faster recovery.
- PEAK PERFORMANCE: Karbolyn enters the bloodstream like a simple sugar, yet it still provides sustained energy without the crash. It's absorbed faster than dextrose, simple sugar, bread, rice, and other carbohydrate products. Enjoy pre, intra, or post training to maximize and maintain high-intensity training, power output, and increase muscle fullness & pumps.
- ALL CARBS AREN'T CREATED EQUAL: Unlike simple carbs that tend to cause a spike and crash or complex carbs that are slow to digest, leaving you feeling bloated and lethargic, Karbolyn combines the best of both by providing you with fast absorption and sustained energy without the bloating or crash. Plus, Karbolyn is 100% sugar-free, gluten-free, stimulant-free, and vegan-friendly.
- MANUFACTURED IN-HOUSE: EFX Sports is part of a very small, elite group of brands who actually make their own products. That’s why we guarantee Karbolyn always meets label claims and is 100% banned-substance free (certified by Informed Sport). With Karbolyn, you'll know you have a pure and potent carbohydrate product.
- 3X QUALITY TESTING: At EFX Sports, we proudly own every phase of the manufacturing process to ensure what's on the label is what's in the bottle...without question. In fact, every EFX Sports product must pass 3 critical quality checkpoints—before, during and after production.

### ⭐⭐⭐⭐⭐ Absolutely amazing!
*by E***K on June 27, 2024*

I've been working out consistently for around 17 years and have been an athlete most of my life. My pre-workout meal has always been my least favorite because I'm never usually hungry at that time and I would always get a little bit sleepy from the insulin spike caused by taking in pre-workout carbs and I absolutely hated that. Yet I knew that my workout performance would suffer if I went into it without having had any recently consumed carbs, so for the longest time I had always just kind of sucked it up and ate some oatmeal or a couple of bananas or something. I came across this product and was skeptical of the claim that this provides a source of carbohydrates that is fast digesting AND also provides sustainable energy. My experience with fast digesting simple carbs is that the energy lasts about as fast as it digests, which is never very long. But after having taken this stuff before every workout for a couple of weeks now, I can confidently say that the claims made by this product are very much legit. It is very fast digesting, doesn't make me feel sleepy at all, and I have felt perfectly fueled throughout every single workout that I have taken it. I lift weights and also do cardio afterwards, so my full workout typically takes me about an hour and a half by the time I'm done. And this stuff has absolutely been able to provide me sustainable energy for my entire workout consistently, for every single workout. This is an amazing product; I can't believe I had never heard of it before. I will never reach for any other source of pre-workout carbohydrates as long as I have access to this stuff.
