We all need vitamins and minerals, and many of us are vitamin and mineral deficient. But what vitamins should you take? How do you know? Sure you could go to the doctor, but often our vitamin and mineral levels can change by the day. Now there’s a new acupuncture pen, called Vitastiq, that when rubbed against the skin tells you what vitamins and minerals you’re deficient in—no more guess work. Vistastiq just completed a successful Indiegogo campaign and should be available for purchase this March for $99.
