These Angstrom Minerals saved me from abandoning my vegan raw food diet! I was struggling with deficiencies prior to taking these. I was feeling week, lacking energy and my skin was erupting in breakouts and looking pail. I attempted to take some mineral supplements in capsule form and my body wouldn't absorb them. They caused me fatigue, chest pains, worst breakouts, etc. So I ordered these Angstrom minerals and within one week of taking them my health turned around drastically for the better! I feel amazing! My skin looks great and I have so much energy. There are ZERO negative side effects when I take them. They have a slight metallic flavor to them but it doesn't bother me at all. I take all of the different minerals offered on this site. I would say these are a MUST for a raw vegan diet!
