Get thyroperoxidasd antibody. If negative, discontinue Levothyroxine and check thyroid tests after 6 weeks. Don’t know much about ashvagandha

I'm wary of supplements that the FDA doesn't investigate. The presence of contaminants that can interfere with your medical conditions or medications is always a possibility. Your pharmacist may have information about this supplement.
