Native Fuel Micellar Casein
What this means
Elite efficiency — 40%+ of calories from protein. Lean meat, whey isolate, low-fat dairy. 90.9% density puts this in the Platinum tier.
Complete dairy protein (milk/casein), high DIAAS, counts in full.
Note: At 2.2g leucine per single scoop, this product sits below the 2.5g threshold needed to maximally trigger muscle protein synthesis in one serving. Common workarounds: use 1.5 scoops, or combine with another protein source in the same meal (e.g., Greek yogurt, eggs). More on the leucine threshold.

Notes
Informed Sport certified native micellar casein, no artificial flavors or sweeteners. Leucine 2.2g per the manufacturer's labeled aminogram (4.9g BCAAs / 10.7g EAAs per serving) — just under the ~2.5g MPS trigger at 1 scoop.
