Caution

Can you take Calcium and Liothyronine together?

Yes, with care — this combination needs a precaution.

Calcium and Liothyronine can be taken together, but the combination needs a precaution.

Why these two interact

Minerals chelate T3 and reduce absorption.

What to do about it

Separate liothyronine and mineral supplements by at least 4 hours.

Timing

Separate Calcium and Liothyronine by at least 4 hours. Taking them in the same window is what causes the issue, not taking them on the same day.
