Whey protein intakes up to 0.4g/kg body mass are well tolerated before a 10km run at 85% of race pace: a clinical trial

Easily digestible protein sources up to 0.4 g/kg body mass consumed one hour before exercise are advised and generally well tolerated, though 0.4 g/kg body mass of protein was associated with increased bloating. However, protein intakes before exercise should be trialed prior to competition due to variations in individual tolerance.
