F · A note from the founder

I built this because nothing on the shelf worked for me.

I was diagnosed with Hashimoto's at 28. Levothyroxine brought my TSH back into range and most of my symptoms stayed. The fatigue, the brain fog, the cold. None of the twelve multivitamins I tried moved the needle.

So I spent two years reading the trials, working with Elena Vayndorf, Ph.D. Research Scientist at the University of Washington. Together we rebuilt what a thyroid protocol should actually look like. Core Axis is what I now take every morning.

"Every active was selected against one criterion: peer-reviewed evidence at the dose that moves clinical markers. For Hashimoto's, methylation status and selenium are non-negotiable."

Three capsules, once a day. Ninety days is the window the formulation was built around.
