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.*

Noticeable size and strength gains while taking it vs when I'm not taking

Of course, monohydrate is a classic and a basic Creatine. But this Kre-Alkalyn does have its advantage - there is really no bloating. I would like to have not 100 grams, but a kilogram of product.

Best Creatine ever. Absolutely ZERO side effects and it DOES work. This willl be the only Creatine I buy!

I am not rating the product, just merely pointing out that this IS Creatine Monohydrate only it is buffered several times. So when you are seeing people go "I did not see any difference I am going back to monohydrate" it is because that person did not read the label that or it did not register for them.

I've used it all now, didn't see any effect on me. Go for mono!

Best Creatine I've ever used. As far as I'm concerned it's the only creatine.

The first time I tried it, I accidentally took 2 about an hour before working out. Had the best chest and arms workout ever but then I started to cramp, so definitely don't make the same mistake. Will report back in a month of use. Currently 155lbs 14%fat.

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

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!

By far the best creatine I have ever taken. No bloat, no water retention, just gains! I have been taking EFX-KRE for close to 4 years straight. It has improved my strength, stamina, and recovery. This is one of the must-have supplements that should be in every weight lifters arsenal!

Excellent product. I've noticed a very nice difference in strength, recovery and endurance after the first couple days. I can lift heavier and do HIIT at the end of my workouts for 20 to 25 mns and sprint full speed and not be out of breath like I used to. And no muscle soreness. the following day. Truly amazing!

This is the first creatine I ever took. I messed up and looked for something better but nothing else worked for me AS well as the powder form. You do have to down the water though (as with any creatine). I personally didn't feel this but my girlfriend felt bloated from it.
