Outcome
Muscle protein synthesis and lean mass with resistance training, adults; daily protein intake target support.
Dose in the literature
20 to 40 g protein per dose; 1.6 g/kg/day total protein is where lean-mass gains plateau in meta-analysis.

§ 5

Not in here

Emulsifier (lecithin)
Lecithin makes whey wet quickly in a shaker. It changes nothing about the protein. Without it the powder clumps; the label says blend it.
Flavor and sweetener
Occupy the serving, change nothing that matters. A single-origin vanilla extract may follow as a separate SKU with its own dossier line.
Thickener (gums)
Mouthfeel only.
Anti-caking agent
Flow in the factory, not function in you.
