Potential Benefits of Creatine for Alzheimer’s

Creatine is a naturally occurring compound involved in energy production, particularly in muscle and brain cells. While it’s best known as a supplement for athletic performance, researchers have also explored its potential neuroprotective effects, including in Alzheimer’s disease.

Creatine shows promise, especially for protecting brain cells and supporting energy in the brain, but it’s not yet a proven treatment for Alzheimer’s. It may one day play a role as part of a larger brain health strategy, but more human research is needed. If you’re considering creatine for a loved one with Alzheimer’s, talk to their doctor first, especially if they have kidney issues or take medications that affect fluid balance or blood pressure. Here’s what we know in layman’s terms:

✅ Potential Benefits of Creatine

1. Supports Brain Energy:
   In Alzheimer’s, brain cells have trouble producing energy. Creatine helps cells make more ATP, the brain’s main fuel, which could support brain function and slow down cell damage.

2. Reduces Oxidative Stress:
   Creatine may act as an antioxidant, helping to protect brain cells from damage caused by free radicals—something that’s believed to play a role in Alzheimer’s progression.

3. Helps Mitochondria Work Better:
   Mitochondria (the cell’s “power plants”) are often damaged in Alzheimer’s. Some research suggests creatine could improve mitochondrial function, possibly helping cells survive longer.

❌ Limitations and What We Don’t Know Yet

• Limited Human Studies:
  Most studies on creatine and Alzheimer’s have been in animals or lab models. There’s very little clinical evidence in actual people with Alzheimer’s.

• Mixed Cognitive Results:
  In healthy adults, creatine has shown some benefits for short-term memory and mental fatigue, but it hasn’t been clearly proven to help in people with dementia.

• Unclear Dosage & Safety for Long-Term Use in Seniors:
  While creatine is generally safe in healthy individuals, the right dose and long-term effects for older adults with Alzheimer’s are not well understood.
