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.
NSF-Certified for Sport®
This product has NSF certification. Which means it can be used safely by professional athletes and will not cause any problems during a doping test.
Because athletes need to know their supplements are trustworthy and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of nearly 300 substances banned by many major athletic organizations.
