After 20 years on synthroid, (thyroxine) can i switch to a natural thyroid supplement?

See below: If you are talking about over the counter thyroid supplements, no. If you are talking about armour (prescription needed), yes.

Natural thryoid med: You can switch to a prescription natural thyroid medication such as armour thryoid or nature-throid. The vast majority of people who try both feel better on natural thyroid. However, some people (those with thyroiditis) may be allergic to some of the components of natural thyroid. Discuss with your doctor.
