Denne studien - selv om den var veldig liten - antydet sterkt at hormonopptaket var bedre når tabletten ble tatt på kvelden.

The researchers suggested several explanations for the results:

•Even when waiting at least 30 minutes to eat, breakfast may be interfering with the intestinal absorption of levothyroxine thyroxine.
•“Bowel motility is slower at night,” which means that it takes longer for the levothyroxine tablet to transit through the intestinal system, resulting in longer exposure to the intestinal wall, and therefore, better uptake of the medication.
•The conversion process of T4 to T3 may be more effective in the evening.
