ON's New Gold Standard Natural 100% Casein Is Pure Micellar

Both strength and endurance athletes appreciate the value of fast-acting proteins like whey, which absorb quickly to provide anabolic and anti-catabolic support for building lean mass. More recently, bodybuilders and other strength athletes have been augmenting their protein supplementation with slowly-digesting casein proteins to support workout recovery, the majority of which occurs during prolonged sleep. Optimum Nutrition (ON) has lead the way in casein quality, and the company’s new Gold Standard Natural 100% Casein™ is absolutely free of artificial flavors, sweeteners and synthetic colors.

“Gold Standard Natural 100% Casein™ is an all micellar casein which has a tendency to gel in the stomach and create a feeling of fullness, making it ideal for between meals or before bed use,” said Rachel Hopkins, a food scientist with ON in Aurora. “The sustained-release of essential amino acids are not only crucial for muscle growth but are also muscle sparing, meaning they help prevent muscle mass from being broken down by the body for fuel.” Each serving provides 24 grams of micellar casein protein including 9.6 grams of essential amino acids.

Since the beginning in 1987, Optimum Nutrition has been a leader in quality and consistency. The company owns and operates state-of-the-art manufacturing facilities to assure the very highest standards of Gold Standard Natural 100% Casein™ – and every other product in the company’s extensive line of powder, capsule, tablet, energy bar and liquid supplements.
