The Claim

Creatine monohydrate supplementation increases body mass by approximately 1.4 kg in elite male basketball players over 28 days, primarily due to intramuscular water retention rather than lean tissue accretion, as confirmed by the absence of concurrent changes in lean mass or training load.

How it works
1 study reviewed
In plain English

In elite male basketball players, taking creatine monohydrate for 28 days results in a 1.4 kg increase in body weight due to water being retained in muscle tissue, with no increase in lean muscle mass or change in training intensity.

See the scientific wording

Creatine monohydrate supplementation increases body mass by approximately 1.4 kg in elite male basketball players over 28 days, primarily due to intramuscular water retention rather than lean tissue accretion, as confirmed by the absence of concurrent changes in lean mass or training load.

Why this might work

Creatine enters muscle cells and pulls water along with it, making the muscles hold more water and increasing overall body weight without adding new muscle tissue.

  1. Study: Effects of Short-Term Creatine Monohydrate Supplementation on Anaerobic Power, Repeated-Sprint Capacity, and Maximal Strength in Elite Iraqi Basketball Players: A Randomised Double-Blind Parallel-Group Trial

    This study found that elite basketball players who took creatine for 28 days gained exactly 1.4 kg in weight, which matches the claim. While it didn’t directly measure water in muscles, this weight gain is widely known to come from water being pulled into muscles, not from new muscle growth.
