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.*

this product is straight flames, no problem with it but what I do have a problem with is's sorry excuse for shipping. I don't know who they pay to ship their products out but I ordered my kre alkalyn July 21st and I literally got it 10 minutes ago Sep 28th what the hell?. I can understand a month maybe because of covid and all but seriously? 2 months?.

BEST CREATINE EVER, was on it for eight months no side effects at all got the muscle mass I wanted believe me it works perfectly well. Now my girlfriend wants 1 year supply of kre alkalyn creatine for Xmas...o'boy.

Havent tried it, but what's the deal with the pricing. Goes from 240 caps for 28 buck and then 260 caps (20 more caps) for over 50 bucks( check your pricing, that's got tot be wrong)

Great customer service from these guys fast delivery. Just started product so can’t really give score on it at moment gave a 10 for service 😁

Currently half way thru the bottle. Noticed my traps seem bigger, also wife believes I've gotten bigger since starting Kre-Alkalyn. Powdered creatine gave me cramps and overall ****** feeling so that was shortlived. No such side effects with this product. I plan on staying off this product for 6 months to 1 year once once i finish the bottle to see and check for any differences. Def recommend this product, especially for ppl who are unable to comfortably take powder creatine.

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!

Mar 29, 2018

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.

Jan 22, 2018

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'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.
