My Story

Working in pharmaceutical research taught me how to critically analyze studies and understand the difference between correlation and causation. When I transitioned to supplement research, I was shocked by the gap between marketing claims and actual evidence. My mission became translating complex biochemistry into practical guidance people can trust.

My Approach

I approach every supplement claim with healthy skepticism and pharmaceutical-level scrutiny. If I wouldn't recommend it to my own family based on the evidence, I won't recommend it to readers.

"In supplement science, the devil is in the details - dosage, timing, and quality matter more than the ingredient itself."
