PH-Correct Creatine Monohydrate Powder. Muscle. Performance. Strength. Clinically Proven. Stable in Liquids. Kre-Alkalyn EFX... It'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. Creatine stability is negatively influenced by acids and liquids at pH 6.9 or less. Kre-Alkalyn EFX (# 6,399,661) is the only creatine with patent protection from pH 7 to pH 14.
