Creatine raises IGF-1

Did you know creatine is perhaps the most researched supplement on the planet? Yet data on the benefits of supplementing with this incredible substance continues to grow. Canadian researchers compared the changes in insulin-like growth factor-1 (IGF-1) amounts in 2 groups of subjects. All the subjects performed at least 30 minutes of structured physical activity 3 -5 X’s per week for eight weeks. The subjects were randomly assigned to one of two groups: One supplementing with creatine, the other, an iso-caloric placebo. Muscle biopsies were taken before and after the training period and analyzed for IGF-1 content. The creatine group had a 24% higher level of IGF-1. The creatine group also had a 23% higher increase in type II muscle fibers. These findings were independent of dietary guidelines. (Int J Sport Nutr Exerc Metab, 2008; 18(4))

What does this mean for the average Joe? It means if you supplement with creatine, you’ll not only get the well known “volumizing” effect, but more muscle fibers.
