Rule 1 Casein

Rule 1 Casein is a slow digesting protein designed to support muscle recovery, maintenance and growth over extended periods. Built around 100% micellar casein, it delivers a sustained release of amino acids, making it ideal for periods between meals or overnight recovery.

Micellar Casein — Sustained Release Protein

At the core of the formula is micellar casein, providing 25g of protein per serving. Unlike whey protein, casein digests slowly and forms a gel like structure in the stomach, allowing for a gradual release of amino acids over several hours. This helps support ongoing muscle protein synthesis and reduces muscle breakdown during longer periods without food.

Overnight Recovery

This slow release profile makes casein particularly effective before bed, where it helps provide a steady supply of amino acids during sleep, a critical period for recovery and muscle repair. It is also beneficial between meals to help maintain a positive protein balance throughout the day.

Complete Amino Acid Profile

Rule 1 Casein provides a complete amino acid profile, including naturally occurring BCAAs and essential amino acids, supporting muscle recovery and overall performance. Each serving is relatively low in fat and carbohydrates, making it suitable for a range of nutrition goals including lean muscle maintenance and body composition support.

Texture & Versatility

The formula is designed to mix into a thicker, creamier texture compared to whey protein, reflecting its slower digestion rate. This makes it suitable not only for shakes, but also for use in recipes where a thicker consistency is preferred.

Stacking with Whey

Due to its sustained digestion, Rule 1 Casein is often used alongside faster digesting proteins such as whey, helping cover both immediate and extended protein needs throughout the day.

Overall, Rule 1 Casein is positioned as a targeted recovery protein, delivering prolonged amino acid release to support muscle repair, recovery and maintenance during extended periods without food.
