EFX Sports Kre-Alkalyn Powder

Buffered creatine· evidence: Limited

Buffered creatine is creatine monohydrate mixed with an alkaline powder such as sodium carbonate. It is marketed as more stable in the stomach and so more effective. A controlled study that compared Kre-Alkalyn with plain monohydrate found no advantage in muscle creatine levels, strength or body composition, and plain monohydrate is already stable in the stomach.

It still provides creatine, so the authorised creatine claim applies when you get 3 g of creatine a day. You are usually paying more per gram for the buffer.

Typical dose: Enough to provide 3 g of creatine a day; check the label

Safety: Same general precautions as creatine monohydrate. Contains a small amount of sodium from the buffer. Speak to your GP first if you have a kidney condition.
