Optimum 100% Casein provides slow, steady protein release to help reduce overnight muscle breakdown and support recovery when you go longer without food. Micellar casein digests more slowly than whey, feeding muscles for hours.

Each serving delivers 24g of quality protein with minimal sugar and fat, making it an excellent option for cutting phases, lean-mass maintenance, or simply curbing late-night hunger.

Use it before bed, between meals, or anytime you want sustained amino support. For a thicker pudding-style treat, mix with less liquid and chill.

Key Benefits

  • Anyone who prefers a pre-bed protein shake.
  • People who want longer-lasting satiety.
  • Shoppers who want the best price in Canada.
