Nowhere in the listing for this Zinc Orotate does it indicate the amount of zinc included in each capsule. I bought it anyway, thinking it the amount would be something reasonable/normal. Well, each capsule has 51mg of zinc. The upper-limit of zinc per day for adults is 40mg! Anything beyond that is too much, can be quite harmful. According to the National Institutes of Health, signs of too much zinc include "nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headaches. When people take too much zinc for a long time, they sometimes have problems such as low copper levels, lower immunity, and low levels of HDL cholesterol." I would therefore NOT recommend taking this Priority One Vitamins Zinc Orotate. I began experiencing low immunity, headaches, and stomach cramps after taking this, until I looked at the label and realized I was 25% above the daily limit for zinc.
