We get questions about vitamins and supplements and we strongly caution you to discuss this with your medical team, however we loved this chart. A great place to begin conversations with your doctors.
The chart is a visualization based on scientific evidence collected by David McCandless and Andy Perkins, that displays vitamins and supplements in “bubbles” and their effectiveness. It is a wealth of information and is updated as new research comes out.
