I had been taking zinc, C and D among other nutrients long before Covid. The day before my J&J shot, and for the week afterward, I took daily 500 mg. Quercetin, 50 mg. zinc, and my usual several thousand IU of D and mg. of C. Ten minutes after the shot, I had NO abnormal feeling in the shot area, and never had any pain, heat or tenderness in that shoulder. Maybe I should be tested to see if I have active immunity or not. My guess is that the immune response would be enhanced, not harmed. I am 83 years old and in good health.
save for later
