it seems that biotin supplementation above 10 mg/day can interfere with thyroid hormone tests. Perhaps vit D & PSA as well?

To be sure we should stop using biotin at least a week before getting any of these tests.

Just FYI!


This was all over our news reports last week.  Thanks for thinking to post it!
