Buffered Creatine (Kre-Alkalyn)

Buffered Creatine (Kre-Alkalyn) is a pH-corrected form of creatine monohydrate synthesized with an alkaline buffer (typically sodium bicarbonate or magnesium), adjusted to a pH of approximately 7.5–14, which theoretically prevents conversion to creatinine in the stomach. Macronutrient composition per standard serving (1.5–3g): Protein equivalent contribution negligible (0g dietary protein), Carbohydrates 0g, Fat 0g, Calories ~0 kcal. Bioactive compound: Creatine content approximately 94–97% pure creatine equivalent per dose, with each 750mg capsule delivering roughly 700–725mg of active creatine. The alkaline buffering agent (sodium bicarbonate) contributes a minor sodium content of approximately 10–30mg per serving depending on formulation. No dietary fiber, vitamins, or significant micronutrients are present. Bioavailability notes: The buffered pH is marketed to improve stability in gastric acid, reducing creatinine conversion by up to 35% compared to standard creatine monohydrate, theoretically allowing effective dosing at 1.5–3g/day versus the 3–5g/day required for monohydrate. Creatine itself is stored primarily in skeletal muscle (~95%) as phosphocreatine, with muscle saturation being the primary bioavailability endpoint. Water solubility is moderate; absorption occurs in the small intestine via sodium-dependent creatine transporter (CreaT/SLC6A8). No significant lipid-soluble components are present.
