the best thyroid supplement
Take with breakfast or a midday meal. Food improves absorption of fat-soluble vitamins (D3).
Swallow with water. No need to space them across the day — the full dose is timed for one moment.
Mineral content (zinc, selenium) requires separation from thyroid medication. Take Core Axis later in the day.
The complete daily panel — every active, every salt, every dose, every role. Printed here, on the bottle, and on every certificate of analysis. Hover any tile or row for context.
“The transparency is what convinced me. Every dose stated, every salt named. As a clinician, I want to know exactly what I am recommending.”
“I had been on three separate supplements to cover the same actives. CoreAxis consolidates them at clinical doses. My TPO antibodies dropped meaningfully over six months.”
“A formulation I can read in thirty seconds and defend in front of a peer-review committee. That is rare in this category.”
Keep the bottles. No labs required, no return shipping, no questions beyond the one we ask ourselves: did it work for you? Apply via your account or email hello@coreaxis.us.
Yes, with a four-hour separation — standard for any mineral-containing supplement. Take levothyroxine on waking, Core Axis with a midday meal.
