APOE4 is a genetic marker that some people carry, and it’s talked about because it’s linked to a higher risk of developing Alzheimer’s later in life.
But APOE4 is not a diagnosis, and it does not mean you will get Alzheimer’s.
We all have a gene called APOE that helps the brain move fats, repair cells, and clear out waste. There are different versions of this gene; APOE2, APOE3, and APOE4.
APOE4 is just one version, but it’s a bit less efficient at the cleanup and repair work, which is why it’s associated with increased risk over time.
People with APOE4 often benefit even more from habits that protect the brain, like:
• Regular movement and aerobic exercise
• Supporting heart, metabolic, and blood sugar health
• Eating whole, nutrient-dense foods
• Prioritizing good sleep
• Staying mentally active and socially connected
Think of APOE4 as a risk factor, not a destiny.
