Why we cite it

A meta-analysis quantifying how total daily protein intake affects muscle and strength gains from resistance training. It finds that dietary protein supplementation significantly augments resistance-training-induced increases in muscle mass and strength, and that benefits plateau once total protein reaches roughly 1.6 g/kg/day (with a confidence-interval ceiling near 2.2 g/kg/day).
