ProteinKey Benefits
How It Works
Whey protein rapidly elevates blood amino acid levels, triggering mTOR-mediated muscle protein synthesis. Rich in leucine (the primary mTOR activator), immunoglobulins, lactoferrin, and cysteine (glutathione precursor). Isolate is >90% protein with minimal lactose.
Dosage & Timing
Recommended Dosage
20-40 g per serving, 1-3 servings daily
Best Time to Take
Post-workout (within 2 hours), morning, or between meals
Recommended Form
Whey isolate (grass-fed, minimal ingredients)
Side Effects
GI discomfort if lactose intolerant (use isolate). Bloating. Acne in susceptible individuals.
Drug Interactions
May affect absorption of certain medications if taken simultaneously. Generally very safe.
What Does The Research Say?
The most studied protein supplement. Proven to increase muscle protein synthesis, support muscle recovery, and aid body composition. Whey isolate is superior for lactose-intolerant individuals. Grass-fed has better fatty acid profile.
