The Claim

In adults with Alzheimer's disease, 8 weeks of daily creatine monohydrate supplementation at 20 grams per day is not associated with changes in brain N-acetylaspartate (NAA) or glutathione (GSH) levels.

In plain English

In adults with Alzheimer's disease, taking 20 grams of creatine monohydrate daily for 8 weeks does not change brain levels of N-acetylaspartate or glutathione.

See the scientific wording

In adults with Alzheimer's disease, 8 weeks of daily creatine monohydrate supplementation at 20 grams per day is not associated with changes in brain N-acetylaspartate (NAA) or glutathione (GSH) levels, suggesting these specific biomarkers may not be sensitive to short-term creatine-induced bioenergetic modulation.

Why this might work

Creatine enters the body and is converted into a high-energy molecule that helps regenerate ATP quickly when cells need energy. This boosts energy production in blood cells, especially in women, but does not change the levels of two brain chemicals linked to neuron health and antioxidant defense, even though the brain also uses creatine.

  1. Study: Bioenergetic data from a creatine monohydrate pilot trial in Alzheimer's disease

    Taking 20 grams of creatine daily for 8 weeks didn’t change two brain chemicals (NAA and GSH) in people with Alzheimer’s, which means those chemicals probably don’t show whether creatine is helping the brain’s energy system.
