I have this wet cough when I take vitamins no matter the brand. I take regular multivitamins, biotin, calcium, magnesium, zinc, vitamin C and potassium. The multivitamins and biotin are really by choice but the rest I really need. I just got over COVID a month ago and I still cannot smell anything, my taste is 10% when I wasn't taking the vitamins no cough now it's back. My grandmother and mom had a similar issue they just stopped taking their vitamins. Has anyone ever heard of this before? How do you fix this annoying cough cuz I need my vitamins. I feel like crap without em!
