ELEMENT 02 OF 08
Whey Protein Isolate
Whey filtered harder: more protein per gram, less lactose and fat.
20 to 40g per serving. Research on daily protein for people who train hard commonly targets 1.6 to 2.2g per kilogram of bodyweight from all food sources combined.
THE SUBSTANCE
WHAT IT IS
Whey is the fast-digesting protein fraction of milk, separated during cheese production. Isolate is whey filtered further to strip out most of the lactose, fat and carbohydrate, typically landing at 90 percent protein or more by weight. It carries a complete amino acid profile with high leucine content.
THE EVIDENCE
WHAT THE RESEARCH focuses on.
Whey protein is most studied for supporting muscle protein synthesis after resistance training and for helping people hit daily protein targets. Research has focused on its rapid digestion and leucine content compared with other protein sources. Isolate specifically gets attention where lactose tolerance is a factor.

STRAIGHT QUESTIONS
Isolate or concentrate: which should I buy?
Concentrate is cheaper and slightly creamier; isolate packs more protein per gram with far less lactose. PRIME blends both with isolate listed first, then adds lactase enzyme to cover the concentrate portion.
Is there a best time to take whey?
Total daily protein matters far more than timing. Use a shake wherever whole food is inconvenient, which for most lifters means right after training.
