CREATINE

Generally safe

Creatine can benefit athletes who need to achieve high speeds for short periods or increase their muscle strength, such as runners, weightlifters, and team athletes.

But while taking creatine may not help all athletes, some evidence suggests that it generally won’t cause harm if taken as directed.

Although an old case study indicated that creatine can exacerbate kidney dysfunction in people with kidney disorders, no effect of creatine on kidney function in healthy people has been shown.

Safety and side effects

If you take creatine orally in appropriate doses, you can safely continue it for up to five years. As with any dietary supplement, it is important to choose a product that follows recommended manufacturing practices and passes third-party product quality assurance testing.

Creatine can cause:

Weight gain, such as body mass without fat in general

Creatine can be unsafe for people with pre-existing kidney problems. However, more research is needed on this topic.
