A new study on creatine reveals no significant differences between the rate of side effects for participants taking a placebo and those consuming the strength training supplement. Researchers conclude that the sports nutrition powder, typically consumed by athletes as a pre- or post-workout shake, offers broad health benefits beyond muscle building, including cognitive support. Dr. Richard Kreider, professor and director of the Exercise & Sport Nutrition Lab at Texas A&M University, US, has spent more than 30 years investigating the effects of creatine.
