    The Vitamin D Revolution

    Vitamin D's influence on key biological functions vital to one's health and well-being mandates that Vitamin D supplementation can no longer be ignored by individuals striving to achieve and maintain a greater state of health. The research on this vitamin keeps coming: cardiovascular health, immune support, bone and joint health, and much more.* This advancement in scientific knowledge about D is especially notable when we consider that we are living in a time of widespread Vitamin D insufficiency. Formulated by John Cannell, MD†, Purity’s Vitamin D complex is a blend of targeted nutrients to complement many of Vitamin D’s health benefits.

    The Dr. Cannell Difference

    Advanced D™ provides a powerful dose of cholecalciferol (Vitamin D) backed by nutrients that work in tandem with this crucial vitamin to support the health of numerous systems within the body.* At the foundation of its design as an answer to widespread Vitamin D deficiency are found a set of other nutrients - key cofactors - added to complement the physiological actions of D. Dr Cannell’s Advanced D™ orchestrates combined actions to make sure that optimal influence is present towards bone, muscle, and metabolic function.*

    The Advanced D Difference - Key CoFactors

    Vitamin D is a team player inside the human body, relying on proper levels of other nutrients - key cofactors - to fulfill its potential in supporting several areas of health. Magnesium is needed by enzymes that metabolize Vitamin D. Magnesium is another nutrient that may run low in the diet. Low dietary Magnesium can contribute to lower levels of circulating Vitamin D.

    Dr Cannell’s Advanced D™ presents a highly bioavailable form of the mineral magnesium as Magnesium Citrate. Zinc plays a role in the Vitamin D receptor, and Boron supports Vitamin D metabolism.* Remarkably, research in humans has found action between Vitamins D and K2, showing a combined effort to enhance bone health and support cardiovascular wellness. Working with Vitamin D, Vitamin K2 helps Calcium find its proper place in the body.*

    Going Beyond D

    In addition to the powerful dosage of Vitamin D, Dr. Cannell’s Advanced D Formula™ delivers a combination of several cutting edge nutritional ingredients shown to help promote proper Vitamin D metabolism and utilization in the body.* Science has shown that supplementation with D or Vitamin K2 can promote bone mineral quality. Working in combination with Vitamin D, Vitamin K2 helps keep calcium in the right places, like the bones.*

    Magnesium Citrate

    As is the case with Vitamin D, knowledgeable healthcare providers are starting to learn that contemporary dietary patterns leave much of the population with insufficient magnesium consumption. Low dietary magnesium may also contribute to a lower level of circulating Vitamin D—yet another barrier to conserving an ideal, strong skeletal structure. Magnesium is involved in over 300 enzymatic processes in human cells, and Dr. Cannell’s Advanced D Formula™ features Magnesium Citrate because it is a form of the mineral shown to be advantageous in terms of absorption.* Magnesium is well known for its contributions to bone health, neuromuscular function, cardiovascular health, and many other essentials of whole-body health, while also becoming recognized for its relation to healthy energy levels and other aspects of a normal metabolism.*


    Taurine is an important amino acid found in many organs, being most concentrated in the heart and the retina of the eye. Taurine is active in muscle function, as well as in maintaining optimal function of nerve tissue, lending itself to neurotransmitter balance.

    Don't Forget Boron

    Dr. Cannell’s Advanced D Formula™ includes FruiteX-B®, a patented boron/calcium complex that has been shown to support normal Vitamin D metabolism, maintain joint comfort and flexibility, and promote healthy bones.* Pilot clinical studies described improvement in Vitamin D status and joint support in subjects consuming FruiteX-B®.*

    Support for Your Bones, Muscles and Athletic Performance*

    Without adequate Vitamin D intake, the body cannot properly metabolize Calcium. Vitamin D strengthens bones and also may enhance muscle strength because of its direct effect on calcium transport in muscles.* Because of its unique interplay with Calcium, Vitamin D can support the health of both of these important structures.* Other ingredients in Dr. Cannell’s Advanced D Formula™ further support the skeletal and muscular systems.*

    A research review published in Medicine & Science in Sports & Exercise by Dr. Cannell, revealed the importance of vitamin D for physical performance. Studies consistently show that athletes perform better when their vitamin D levels are higher, due to increase exposure to sunlight in the summer months.

    Powerful Immune Support*

    Vitamin D also has an interesting role as a regulator of the immune system.* D has unique immune-modulating properties that can support health and wellness by supporting innate immunity. For additional support, Dr. Cannell’s Advanced D Formula™ contains Zinc, another immune-supporting nutrient.

    Heart and Cardiovascular Support*

    Recent research points to the importance of Vitamin D in maintaining healthy heart function.* Dr. Cannell’s Advanced D™ takes this research a step further by combining Vitamin D with key co-factors added to complement the physiological actions of Vitamin D.* Dr Cannell’s Advanced D™ orchestrates combined actions to make sure that optimal influence is present towards bone, muscle, and metabolic function.*
