A New Type of Complete Protein

Promix Beef Protein is a first-of-its-kind hybrid protein.
It delivers a complete amino acid profile while naturally supporting skin and joint health, bringing together benefits associated with both collagen and whey.

Whey Protein Isolate
  • Muscle first
  • Amino acid profile that is the best for muscle building and post-exercise recovery
  • A complete protein
  • Does not contain as high levels of amino acids related to joint, skin or gut support
Beef Protein Isolate
  • Same connective tissue benefits of collagen, while also aiding muscle recovery
  • Dairy-free/lactose-free protein source
  • Easier on digestion
  • Hydrolyzed for faster & easier digesting, better amino acid uptake, better recovery
  • A complete protein
Collagen Benefits
  • Joint health + bone density
  • Dairy free/lactose free
  • Easier on digestion
  • An incomplete protein, not well suited for muscle recovery
