I just completed all my function health tests. It took TWO Tuesdays to do this and 24 vials of blood, including a urine test. Was totally worth it. Check out my video explaining why these tests are so very important if you are looking for optimal health. I also believe the ORGANIC ACIDS testing is just as important. If you can complete these two tests you will have all the information you need to correct imbalances and deficiencies, and have the right guidance to abundant health. It is then up to you to apply the health protocols.
