Effects of Creatine Pyruvate and Citrate on Exercise Performance
Creatine monohydrate has to be one of the most popular supplements for athletes and bodybuilders. It has been found to increase the effects of weight lifting on muscle volume, strength, and power.
Pyruvic acid has been shown to improve endurance exercise capacity. It sounds like it would be promising to combine creatine monohydrate with pyruvic acid, expesially for those that participate in sports that require both endurance and high intensity abilities.
A study by the Journal of the International Society of Sports Nutrition (JISSN) examined the effects of 28-days of creatine pyruvate, creatine citrate, or placebo supplementation on endurance capacity and intermittent handgrip power.
The study was performed on 49 healthy males. Participants consumed 5 grams per day of either creatine pyruvate or creatine citrate, or a placebo.
The results proved to be promising, especially for creatine pyruvate.
Body weight increased in both creatine groups by a similar amount, but the placebo group remained unchanged. Forearm circumference increased significantly in both creatine groups.
Both creatine groups experienced a significant increase in mean power, but the placebo group showed no change.
Creatine pyruvate improved contraction velocity and fatigue resistance during intermittent exercise of high intensity due to enhanced contraction and relaxation velocity. Unfortunately, the performance benefits from creatine citrate decreased with time.
I have had decent success with creatine monohydrate and plan to stick with that. I have not seen a creatine pyruvate supplement in a while, but remember them as being fairly expensive.
