The Claim

Creatine monohydrate supplementation at a dosage of 5–10 g/day for a duration of 4–8 weeks is generally well-tolerated in adults with major depressive disorder, with mild gastrointestinal side effects reported and no significant increase in serious adverse events compared to placebo.

Description
1 study reviewed
In plain English

In adults with major depressive disorder, taking 5–10 grams of creatine monohydrate daily for 4 to 8 weeks is associated with mild gastrointestinal side effects but does not increase the rate of serious adverse events compared to a placebo.

Why this might work

Creatine enters the brain and gets converted into a high-energy storage molecule that quickly replenishes the brain's main energy currency. This extra energy helps brain cells in areas that control mood work better, especially when they are under stress, which reduces symptoms of depression.

    Taking creatine daily for up to 8 weeks helped some adults with depression feel better, and most people didn’t have serious side effects—just a little stomach upset in some cases, similar to those taking a sugar pill.
