Thorne Thyrocsin

Thyrocsin from Thorne is a thyroid formula containing ashwagandha, L-tyrosine, iodine, selenium, copper, zinc and vitamins B12, C, E. Iodine and selenium are known for their supportive effects on the thyroid gland and thyroid hormone production. The other ingredients make a magnificent addition and work as co-factors in this formula.

Re-introduction

About 10 years ago, Thyrocsin was one of our most popular Thorne products. Unfortunately we had to take it out of our range due to new EU legislation. Fortunately Thorne has adapted the composition so now we can sell it again.
