Do peptides interfere with levothyroxine?

The standard rules for levothyroxine still matter most. Take it the same way every day, usually away from food, calcium, iron, and many supplements that can block it. Research peptides are a separate question. There is no large, high-quality chart of every peptide against levothyroxine. Do not assume natural or research means no interaction. Ask the prescriber or pharmacist before adding anything injected, or any high-dose pill, near the time you take your thyroid dose.
