1. How Herbal Supplements Affect Synthroid Absorption
Synthroid works best when taken on an empty stomach, but certain herbs can alter its effectiveness. The key factors include:- Fiber-rich herbs (e.g., psyllium husk) – May bind to levothyroxine, reducing absorption. - Calcium & iron-containing herbs (e.g., horsetail, nettle) – Can interfere if taken too close to Synthroid. - Thyroid-stimulating herbs (e.g., ashwagandha, bladderwrack) – May boost or disrupt thyroid function.
Best Practice: Take Synthroid 30-60 minutes before breakfast and wait 4 hours before consuming herbal supplements that may interfere.
