Why do you have to wait to eat after taking synthroid?

After taking Synthroid (levothyroxine), it's recommended to wait at least 30 to 60 minutes before eating because food can interfere with the absorption of the medication. Certain foods, especially those high in fiber, soy products, and calcium, can bind to the hormone and reduce its effectiveness. Additionally, taking Synthroid on an empty stomach improves its bioavailability, ensuring that the body receives the intended dosage for optimal thyroid function.
