Casein, similar to whey, is derived from a milk protein source. This type of protein offers a slow-digesting protein, perfect for overnight muscle recovery. For this reason, casein is commonly taken a few hours before bed, giving the body sufficient time to take in all the amino acids. 100% Casein Gold Standard Protein can also be taken any time of the day for those extended periods in between meals.

100% Casein Gold Standard Protein is a time-release protein supplement that gets absorbed slowly by the body and helps to facilitate muscle recovery and growth. Due to this, it acts all day long, gradually supplying the body with much-needed amino acids. As the micellar casein used in this supplement forms a viscous gel when it comes in contact with the digestive juices, it gives a feeling of fullness, which helps support fitness goals.

What does Gold Standard 100% Casein stack well with?

•  Whey Protein Blends: many people pair a fast-digesting whey during the day with casein at night, for round-the-clock protein coverage.
  
• Amino Acids: casein already contains naturally occurring BCAAs, but an extra amino acid supplement can support recovery and endurance further.
  
•  Creatine Supplements: Taken daily alongside casein, it stacks well for anyone focused on overnight recovery and long-term muscle growth.
