Not really, but some research carried out in Australia has shown that there may be a potential interaction between celery seed tablets and the thyroid medication, thyroxine.
The evidence suggests that celery seed extracts can cause a decrease in thyroxine levels. So if you are taking thyroxine, you might want to check this out with your doctor.
Celery Seed.
Sorry for the late response to Octavius and SupaStar - was off sick.
I bought these tablets as I read they were excellent for the joints and they also assist bloating, but thought I better consider the Thyroid issue first. I guess I'd better ask my doctor before I start taking them then.
No, fortunately, my hair is not thinning, but I know that is a symptom of an under-active Thyroid - so I am lucky there.
