Creatine and its effects on hydration

When it comes to sports nutrition and supplements, creatine is a term that comes up a lot. Creatine is a naturally occurring substance that is produced in our body and plays an important role in fueling muscles. It is also used as a dietary supplement to improve athletic performance.

One of the effects of creatine that is often discussed is its effect on the body's hydration. It's often thought that creatine can cause dehydration because it draws water out of the cells.

However, there are several studies that have shown that creatine can actually have a hydrating effect. A 2003 study found that creatine can increase water absorption in cells, leading to improved hydration.

Another possible mechanism by which creatine may affect hydration is through its ability to increase muscle cell volume. When creatine is stored in muscle cells, it binds to water, resulting in an increase in muscle volume. This can help keep cells hydrated and improve performance during exercise.

However, it is important to note that the effects of creatine on hydration can depend on various factors, such as individual tolerance and dosage. Some people may be sensitive to creatine and may experience reduced hydration. It is therefore advisable to consult a doctor or nutritionist before taking creatine.


Creatine is a popular dietary supplement that is often used to improve athletic performance. Although it's often thought of as dehydrating, there's evidence that creatine can actually have a hydrating effect. It can increase cellular water absorption and increase muscle volume, which can result in improved hydration. However, it is important to consider individual differences and seek professional advice before taking creatine.
