                                According to the American Thyroid Association, timing is crucial for proper absorption of thyroid medication. Numerous studies have confirmed that consuming coffee, particularly with tablet-based levothyroxine, can significantly hinder drug uptake. This interference can lead to unstable thyroid hormone levels, impacting the effectiveness of treatment.
