Can creatine help me gain weight?

Creatine can help you gain weight, but the jump you see on the scale doesn't necessarily reflect increased muscle mass (or fat, for that matter). Most evidence suggests that the pounds are likely just water weight. Here's why: Creatine helps generate the energy muscles need to work. When you take creatine supplements, the amount of creatine in muscle cells increases, drawing water in along with it. However, some preliminary evidence suggests that creatine may boost the activity of cells that eventually develop into muscle tissue, and it may also help athletes to work out harder by increasing their energy stores. Both effects could lead to more muscle mass, but more research is needed.
