This is a double blind, randomised, placebo-controlled, parallel-group trial to evaluate the effect of Maolactin FMR supplementation on post exercise inflammation, exercise recovery and muscle fatigue and pain in an otherwise healthy population of adults 18-65 years old over 10 weeks with 8 weeks of supplementation. This is PART A of the study.
