Creatine HCl Beat Monohydrate in Soccer Players—Don't Toss Yours Yet
A new randomized trial in 40 soccer players found that creatine HCl and ethyl ester out-gained plain monohydrate on jump, sprint, agility and peak power after just four weeks. Every creatine form beat placebo, but the "fancy" versions pulled further ahead on the explosive measures. Before you swap tubs, though, the study has just 10 athletes per group, no reported doses in the abstract, and a result that clashes with earlier research. Here is what it showed, what it did not, and how to think about it.
Kre-Alkalyn's Label Dose Didn't Lift Muscle Creatine, Biopsies Show
Buffered creatine like Kre-Alkalyn promises better absorption, lower doses and less bloating. A double-blind Texas A&M trial put that to the test with actual muscle biopsies in 36 trained lifters over 28 days. At the label dose of 1.5 g/day, muscle creatine barely moved, while monohydrate raised it clearly more. Strength, body composition and side effects showed no advantage for the buffered product. Here is what the numbers show and how to dose creatine instead.
Creatine Pyruvate vs Citrate: One Form Kept Force Up Longer
Two fancy creatine forms beat placebo in a 28-day trial, but one kept muscle force elevated through all ten all-out intervals while the other faded. Creatine pyruvate raised force in every interval (p < 0.001), whereas creatine citrate's benefit disappeared by the sixth interval. Only pyruvate also improved relaxation velocity and resting oxygen consumption. Before you ditch your tub, there's a major catch: the study had no creatine monohydrate group. Here's what the numbers show, what they can't, and how to choose.
Creatine Ethyl Ester vs Monohydrate: The Pricey Form Lost
Supplement makers love to sell "advanced" creatine as better absorbed than the old standby. A 2009 double-blind trial tested creatine ethyl ester against monohydrate and placebo in 30 untrained men over seven weeks of heavy training. CEE produced lower serum creatine and sharply higher serum creatinine, a pattern consistent with it breaking down into waste. Muscle creatine rose in both creatine groups, but strength, power, and body composition did not differ between any groups. The takeaway: skip the premium form and keep it simple.
