Rule 1 Casein delivers 25g of slow-digesting protein designed for overnight recovery and sustained amino acid support. This is the protein you take when the goal is growth, repair, and waking up stronger than you went to sleep.
Powered by pure micellar casein, it forms a gradual-release protein matrix that feeds muscles for hours. That means fewer breakdown periods and more productive rebuilding while you rest. Low in carbs and fat, with 600mg of calcium for muscular and skeletal support, this formula is built for lifters who train hard and take recovery seriously. Smooth, rich chocolate flavor makes it easy to enjoy nightly — no chalk, no clumps, no sludge.
Micellar Casein Protein:
Supports extended amino acid release for overnight repair and muscle retention.
Performance Flavor & Texture System: Cocoa (processed with alkali), cellulose gum, xanthan gum — crafted for smooth, consistent mixability without grit.
Smart Sweetening System: Sucralose + Acesulfame Potassium — delivers satisfying chocolate taste without added sugar.
Contains: Milk & Soy.

Mix 1 scoop with 8–12 oz of cold water or milk before bed, or anytime sustained protein release is desired.
We carry Rule 1 Casein Protein because athletes don’t grow in the gym — they grow while they recover. This formula provides slow, steady protein absorption that supports overnight repair, better muscle retention, and improved recovery efficiency.
Q: When should I take casein?
A: Best before bed, or anytime extended protein support is needed.
Q: What makes casein different from whey? A: Whey absorbs fast. Casein absorbs slow. Casein is ideal for sustained recovery — especially overnight.
Q: Can I stack this with whey? A: Absolutely — whey after training, casein before bed is a strong muscle-building routine.
Q: Will this help with soreness? A: It supports recovery processes that reduce breakdown — helping you feel more prepared for the next session.
