How It Works
How It Works
Micellar casein forms a gel-like substance in your stomach, releasing amino acids slowly over 7 hours. This sustained release prevents muscle breakdown during overnight fasting periods when your body typically goes without nutrients for hours.
Who It's For
Serious athletes who want overnight muscle recovery support. Adults following high-protein diets for muscle building or weight management. Anyone looking for a filling, low-calorie protein option.
Who It's Not For
Those wanting immediate post-workout protein absorption should choose whey instead. Not suitable for individuals with milk protein allergies.
About This Product
What It Does
Rule One R1 Casein provides 7 hours of steady muscle-feeding protein while you sleep. Unlike whey protein that absorbs quickly, this 100% micellar casein creates sustained amino acid release that works all night long.
Why It Works
- SLOW ABSORPTION: Micellar casein takes up to 7 hours to fully digest, providing steady amino acid delivery when your body needs it most.
- COMPLETE PROTEIN: Each 33g serving delivers 25g complete protein plus 5g BCAAs to support muscle protein synthesis and reduce breakdown.
- OVERNIGHT ADVANTAGE: Research shows casein is more effective than soy protein at increasing plasma amino acids during sleep and enhancing whole-body protein synthesis.
What's Inside
Clean micellar casein formula with natural vanilla flavour. Low fat (under 2g) and low carb (under 6g) per serving. Manufactured in GMP facilities with strict quality control.
Why we carry it: Rule One uses the purest, most expensive form of casein protein available with proven slow-release benefits backed by research.
