Started taking Pure Encapsulations Trace Minerals after struggling for years with chronic low blood sugar, low blood pressure, and constantly catching every sickness going around. Since adding this to my daily routine, I have noticed a massive improvement in all three areas. My numbers have stabilized and so far Ive gone over three months without getting sick (a huge improvement for me). Zero side effects. My only complaint is that they don't come in a bigger bottle with more servings. Overall, 10/10 and I highly recommend.
