Creatine

For exercise performance and brain health

The experts we follow agree on this.

Creatine is a well-supported choice for muscle, brain, and mitochondrial energy.

Who is behind it

Voices including a molecular biology PhD, a licensed acupuncturist and clinician-educator and a nutritional sciences PhD.

How strong the research is

Mostly expert experience so far, with published research still catching up.

Ask the minds about this

In their words

“I think everyone who's not eating one or two pounds of meat per day should probably be taking creatine.”

  • Creatine can improve cognitive function especially if your brain is stressed and benefits brain health by improving brain function and speeding up recovery from trauma.

  • GAMT polymorphisms affect creatine synthesis impacting muscle mass and speech development; supplementation can be beneficial.

  • Creatine supplementation provides multiple benefits for women including strength gains, bone health, brain function, metabolism support, and recovery.

  • Creatine is one of the most studied supplements proven to be safe and beneficial for muscle mass and brain function.

With care

Some of the minds attach conditions. These are worth reading before you begin.

  • There is no evidence of harm from creatine while nursing, and it may help reduce fatigue and improve energy, but research is lacking so caution is advised.

  • Creatine works well in non-athlete sedentary middle-aged women with brain fog, low energy, mood instability, and difficulty thinking clearly, improving energy, stability, and cognition.

  • Creatine is not necessary for strength training but provides visual and strength benefits with minimal side effects.

Where they disagree

Both sides

For

Against

Creatine does not structurally contain arginine as a backbone, so it should not promote cold sore outbreaks.

Most of the minds come down in favour, and the dissent is worth knowing.

How this reading was made
