Read this book for college back in 2010's. (can't believe its almost 2020). Anyway, great book, great content, if not a little bit dry like a lot of textbooks are. It basically just presents the facts. Lots of good details to refer back on if you're unsure of recommended doses of vitamins, interactions between competing nutrients, and other good information for general health. I might copy some pages and post them on the wall or refrigerator, because it has some pretty good charts. ( )
