Product Overview

EFX Sports Kre-Alkalyn EFX. Muscle*. Performance*. Strength*. Technologically Advanced.

pH-Correct Creatine® Monohydrate

EFX Sports Karbolyn Fuel. Designed to support Energy*, Endurance* and Recovery*


Kre-Alkalyn's Buffered. It's Stable.

Kre-Alkalyn® EFX represents a major breakthrough in performance supplementation thanks to its multi-patented, pH-Correct creatine® stabilization technology. Our Scientist Dr. Jeff Golini discovered that “buffering” to pH-12 produced a stable creatine monohydrate molecule.*

pH-Correct Makes it a Category of One!
Kre-Alkalyn® EFX is the only creatine monohydrate product with a pH of 12 because its molecules are synthesized with ‘buffering’ agents using a patented (#6,399,661) manufacturing process to make it pH-Correct.*

Karbolyn graph

Creatine stability is negatively influenced by acids and liquids at pH 6.9 or less. (#6,399,661). Kre-Alkalyn® is the only creatine with patent-protection from pH 7 to pH 14.*

I've been competing as a bodybuilder since I was 14. This is one of the best creatine I've come across in a while I used it back in the day and I still use this product no cramping, no bloat, strength goes up, lean gains I like this product so much my fiance uses it also

I have been taking the prescribed dosage of 2 capsules a day (1 before/1 after workout) for over a month now and I have definitely seen an improvement in my lifting strength, stamina and recovery times. I am now able to power through my entire workout without losing too much intensity. I have also noticed that almost all my lifts have gone up by 12-15%. My recovery time after my workout has also improved. I have experienced no ill effects, like bloating etc. My water intake is not very high. Probably around 2-2.5 litres a day. Even with this intake, I have had no issues whatsoever. I would be happy to recommend this to anyone. In my experience, I can confidently say that this product is, easy to consume, has no side effects and definitely helps improve lifting stamina and recovery times.

Don't work. Was on it for over a month and loss gains . I'm back to monohydrate

Verified Buyer

Definitely a great product! It's very convenient having creatine in capsule form; makes it much easier to consume especially if you're an "on the go" type of person. However, I feel more effectiveness when I consume creatine in powdered form. I took a capsule before my workout along with my pre-workout drink, and one post workout along with my post-recovery shake. It definitely helped me get in those few extra reps in. This product definitely helped me increase strength and size. On top of that, it didn't make me feel bloated!

I've been using it for three years now, and it definitely made me stronger. No bloating whatsoever and it's easy on stomach. Love the fact that it comes in a capsule form. Great product!
