The Claim

Daily supplementation with 20 grams of creatine monohydrate for eight weeks increases serum creatine levels from a baseline of 0.6±0.4 mg/dL to 15.0±13.6 mg/dL in adults with probable Alzheimer’s disease.

Source: 450 Eight weeks of creatine monohydrate supplementation is feasible and associated with increased brain creatine in patients with AD

In plain English

Taking 20 grams of creatine monohydrate every day for eight weeks raises blood creatine levels from an average of 0.6 mg/dL to 15.0 mg/dL in adults diagnosed with probable Alzheimer’s disease.

See the scientific wording

Daily 20-gram creatine monohydrate supplementation for eight weeks significantly increases serum creatine levels from baseline (0.6±0.4 mg/dL) to 15.0±13.6 mg/dL in adults with probable Alzheimer’s disease, with 90% average self-reported compliance.

Why this might work

When a person takes creatine powder by mouth, it passes into the bloodstream, raising the amount of creatine in the blood. This high blood level pushes creatine into the brain through special transporters in the blood-brain barrier. Once inside brain cells, creatine builds up and stays there, increasing the total amount of creatine in the brain.

  1. Study: 450 Eight weeks of creatine monohydrate supplementation is feasible and associated with increased brain creatine in patients with AD

    The study found that when older adults with Alzheimer’s took 20 grams of creatine every day for 8 weeks, their blood creatine levels shot up more than 20 times — just like the claim said — and most people took it as directed.
