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.

“I'm not on medication due to the fluctuation of my numbers. The Myo-Inositol 600mg is what is recommended after studies and no digestive issues after taking them.”
“It has a lot of compounds within it so I cannot combine with my normal multivitamin. At least this will save me money.”
“I noticed more focus, improved energy, and an overall sense of well-being. Of course, individual results may vary, but I was pleased with my experience.”

A multivitamin is built for population-level deficiency prevention at minimum effective doses. CoreAxis is built for one autoimmune condition at therapeutic doses, using only forms with established bioavailability. The two products solve different problems.
