Optimum Nutrition Gold Standard 100% Casein Protein Chocolate is a premium slow-digesting protein powder specially formulated to support muscle recovery, muscle maintenance, and sustained protein nutrition during sleep or between meals. Each serving provides 24g of high-quality Micellar Casein Protein derived from milk, delivering a gradual release of amino acids over several hours to support muscle protein synthesis and recovery. Unlike fast-absorbing whey protein, Micellar Casein digests slowly, making it an ideal choice for nighttime supplementation and extended periods between meals. The formula provides 9g of naturally occurring Essential Amino Acids (EAAs), including Branched-Chain Amino Acids (BCAAs), which contribute to muscle repair and maintenance. Enriched with Magnesium and Zinc, it supports normal muscle function, energy metabolism, and protein synthesis. Cocoa Powder delivers a rich chocolate flavour, while Lecithin improves mixability and Sucralose and Acesulfame Potassium provide sweetness. With a low sugar and fat content, Optimum Nutrition Gold Standard Casein offers convenient protein supplementation for athletes, fitness enthusiasts, and active individuals seeking to meet their daily protein requirements and support overnight muscle recovery
