Ok guys, I hear a lot of people raving about Kre-Alk, and companies like SciFit and All American boasting its superiority over creatine monohydrate. The companies all cite a study done on Bulgarian Olympic weight lifters for their claims. Yet the study DOES NOT back these claims at all. So let's review:
All American claims that "At low doses (1.5 - 3 grams) Kre-Alkalyn® boosts endurance and training capacity for up to three hours." However, the lifters used in the study each took 7.5 grams per day. At this amount, the cost of NutraPlanet brand Kre-Alk (I believe the cheapest out there) would be almost $2 per day. This is about 20 times the cost of the same amount of creatine mono.
All American also claims that the men in the study who used Kre-Alkalyn gained "28% more raw power" than the men who used creatine monohydrate. This may have been valid, but there is nothing in the study to suggest that this is a significant difference. In every clinical trial, there is bound to be regular sampling variation for each observance of data. For trials like these, statistical analysis of the data using 2-sample T-tests or ANOVA is required. These tests determine whether or not the difference of the means in the tested groups is significant enough to attribute to the test variable. This is concluded based on the resultant p-value, a number which gives the likelihood that the difference between the means could have occurred by chance. For a study like this one where type 2 error is not a huge issue, the p-value must be less than .05 to conclude that the difference between the means is significant. Absolutely NO p-value for any of the results was given in this study. There can be two reasons for this:
1) The researchers didn't test for significance, which would technically nullify all claims made by the study.
2) The researchers found p-values, but they were higher than .05 and therefore were not worth including in the results.
Finally, the study did admit that there was no difference in size gain between the two groups.
To conclude, Kre-Alkalyn may in fact be a legit product. But the study on Bulgarian athletes does not back this in any way. So why do people rave about it? I can't say for sure, but my best guess is that in terms of chemical composition Kre-Alk is closer to creatine monohydrate than any other creatine variation, and monohydrate has been proven time and time again to give results. Kre-Alkalyn might give good results, but as I have made quite clear above, it does not seem to be worth the extra cash.

Hope this turns some heads XD
