Nutritional scientist, Dr Chris Masterjohn, PhD, is today’s guest interview. Chris shares with us the best ways to start assessing your nutrient status and how he came up with a cheat sheet - Testing Nutritional Status: The Ultimate Cheat Sheet to help guide us in understanding the blood test numbers. He explains what current lab tests and RDA’s tell us and why they aren't always the best indicator of nutrient status for vitamins and minerals. We then find out about depletion/repletion studies and the problem with a general lack of data. We also go into discussing other key information in determining deficiencies such as diet, lifestyle, genetics and general signs and symptoms as well as tips on before and after testing, food vs supplements and low-carb/keto diets.
