Scientist describes her personal brain-health plan at 50, from genetics to experiments

What if your genetics could help you identify which areas of brain health are worth paying more attention to? After reviewing my 3X4 Genetics results, Memory & Brain Health ranked as one of my top three pathways—and one result immediately caught my attention: BDNF Val66Met, a genetic variant involving brain-derived neurotrophic factor (BDNF), a protein involved in neuroplasticity, learning and memory. As a PhD scientist focused on longevity and precision health, I didn't look at that result and think, “I have a bad gene.” I asked a different question: How can I use this information to build a smarter brain-health strategy for myself at 50? In this video, I'm taking you behind the scenes of exactly how I think through that process. I break my personal brain-health protocol into three categories: FOUNDATION → OPTIMIZE → EXPERIMENTAL. We’ll talk about the interventions with the strongest evidence—including exercise, strength training, Zone 2, sleep, metabolic health, omega-3s, a Mediterranean/MIND-style diet and polyphenols—and why these remain the foundation no matter how exciting the latest biohack may sound. Then we get into the things I'm personally optimizing and experimenting with, including sulforaphane, fasting, ketone esters, C8 MCT oil, periodic nutritional ketosis, PEMF, Semax and low-dose tirzepatide/GLP-1 signaling. I also explain why BDNF becomes particularly interesting during menopause, what we know about the relationship between estrogen, BDNF and neuroplasticity, and where the science is still evolving. One of the most important distinctions in this video is this: Mechanistically interesting does not mean clinically proven. I'll show you which strategies have strong human evidence, which have promising evidence, and which are experiments I'm choosing to explore based on my own biology and personal experience. Because this is what precision health means to me. It's not finding one genetic variant and taking a supplement for it. It's looking at genetics + biomarkers + lifestyle + symptoms + personal goals and figuring out where your highest-leverage opportunities actually are. And my protocol isn't going to be your protocol. That's the point. If you'd like help looking at your own genetics, biomarkers and longevity goals and building a more personalized strategy, you can find information about working with me below.
