(Question) If I have thyroid problems, can I not drink cabbage juice?

I've been drinking cabbage juice regularly lately because of poor stomach health. While researching the effects of cabbage juice, I found a recommendation for people with hypothyroidism to be cautious. I took Synthroid for a year for my hypothyroidism. I'm no longer taking the medication, but I'm still monitoring my blood levels through health checkups. Should I stop drinking cabbage juice? I'm curious if anyone is currently drinking it.
