Product details

Optimum Nutrition Gold Standard 100% Casein delivers high-quality micellar casein designed to provide prolonged muscle recovery support. Unlike rapidly absorbing whey, casein reacts with stomach acids to thicken, slowing down the breakdown process into amino acid subcomponents.

This steady release makes it an ideal nutritional bridge between meals and an exceptional choice for consumption right before bedtime when the body experiences extended hours without food. Formulated for fitness enthusiasts, bodybuilders, and athletes looking to preserve lean muscle mass, this premium formula helps keep you full while preventing muscle breakdown.

Each serving delivers substantial protein, essential amino acids, branched-chain amino acids, and high calcium content. Enhanced with Aminogen enzymes, this slow-acting protein powder ensures optimal digestion and nutrient utilization, helping you maximize your fitness results even while you sleep.

  1. Add one scoop of the powder to ten to twelve ounces of cold water, milk, or your preferred beverage.
  2. Stir, shake, or blend for thirty seconds until completely dissolved.
  3. For best results, consume between meals or right before going to bed to feed your recovering muscles.
