Formulated to Win! PH-Correct Creatine Monohydrate Muscle Performance Strength Dietary Supplement Clinically Proven The Original Purple Cap Informed-Sport Trusted by Sport Kre-Alkalyn EFX It's Buffered. It's Stable. Kre-Alkalyn EFXC represents a more 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 (#6,339, 661) manufacturing process to make it pH-Correct. Creatine stability is negatively influenced by acids and liquids at pH 6.9 or less (#6,399,661). Krea-Alkalyn is the only creatine with patent-protection from pH 7 to pH 14.
