Creatine

Creatine isn't just for athletes. Your brain uses a surprising amount of energy to function, and creatine plays a direct role in how that energy gets produced and used. When mental fatigue sets in, it may be a sign your brain's energy systems need support.

What the Research Suggests

Research suggests creatine supplementation may help reduce mental fatigue, support memory, and improve cognitive performance during sleep deprivation or high-stress periods. Benefits appear most pronounced in vegetarians and vegans, who typically have lower baseline creatine stores from diet.

Therapeutic Amount Studied

Most cognitive research has used 5 grams of creatine monohydrate daily, similar to the standard dose studied for muscle and performance benefits.

Can You Get It from Food?

Yes, to a degree. Creatine is found in red meat and fish, but a typical diet provides only about 1–2 grams a day, well below the amount used in cognitive research.

Vera Life Take

Creatine is one of the most well-researched supplements out there, and its role in brain energy is a newer, exciting angle. If you eat little to no meat, this may be one of the more practical additions for mental fatigue. One note: if you have existing kidney concerns, check with your doctor first, since creatine is processed by the kidneys.
