Micellar Casein Peanut Butter Cup by Catalyst

Hormone Free
All Natural
Made In USA

For high performance athletes and hard training competitors, reaching their required daily protein intake is of the utmost importance... even while they're asleep. Supplementing with Catalyst Micellar Casein is ideal for before bed and other long stretches of time where you're likely not taking in any food or nutrients for hours.

CATALYST by Strength.com Micellar Casein has been formulated by experts to help athletes achieve their best results possible by fuelling the body during this crucial recovery period.

  • SLOW DIGESTING protein source allows for the sustained release of amino acids into the bloodstream thereby feeding your muscles as you sleep.
  • SAVE your hard earned muscle gains and help stave off muscle breakdown and catabolism.
  • NATURALLY SWEETENED with Stevia Leaf Extract for a delicious Peanut Butter Cup taste you’ll love!

Fast digesting amino acids, like whey, can clear the GI tract in under an hour, which make it desirable during or immediately after exercise to refuel recovering muscles, but slow digestion and absorption may be more beneficial at other times – including bedtime when your body typically goes for hours without food. Casein proteins thicken in the stomach and can take up to 7 hours to completely digest into its amino acid sub-components.

Micellar Casein is the ideal supplement for bedtime consumption, or consumption during long meal-to-meal intervals when eating whole foods is not an option.
