Dietary control
Participants recorded their dietary intake on day 7 of the familiarisation trial and were instructed to replicate this intake on the two supplementation trials. On this day they were instructed to limit their intake of protein-rich foods (a list was provided), avoid consuming any caffeine after 11:00, and attend the lab ≥ 2 h post-prandial. Participants were given a low-protein evening meal to consume at home consisting of 1 × 250 g pack of White Golden Vegetable Rice (Tesco, PLC, Herts, UK) and 2 × 37 g Nutrigrain Blueberry bars (Kelloggs, Michigan, US). After this meal they avoided any food or fluids other than water and their respective supplements 1 h before bedtime until after their lab visit on day 8.
