Field notes for APOE4 carriers

Your genes aren’t your destiny. Get ahead of APOE4.

Just found out you carry APOE4? One copy roughly triples Alzheimer’s risk and two copies raise it further, but a large share of that risk is modifiable. We turn the research, podcasts, and expert guidance into clear steps for protecting your brain and heart, with the real numbers and the honest uncertainty left in.

Free, and built for carriers by people who actually read the studies.
