I’ve been taking zinc carnosine for a couple days after a short stint with apple cider vinegar. I believe I may have gastritis and ACV really irritated it. I stopped the ACV and started zinc carnosine afterwards to hopefully heal some of the damage. I’m fine during the day and I take my zinc carnosine 2 hours before bed since I discovered it makes me sleepy. I notice a couple hours in that my stomach is not feeling great in bed. I feel heartburn! Same happened nights before but I didn’t connect it to the zinc carnosine. Why is it causing me stomach irritation!? Doesn’t make sense. Isn’t it suppose to heal?
