    The Vitamin D3 Revolution

    Vitamin D's influence on key biological functions vital to one's health and well-being mandates that Vitamin D3 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 D3 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 with Calcium & Magnesium is a blend of targeted nutrients to complement many of Vitamin D3’s health benefits.

    The Dr Cannell Difference

    Dr Cannell’s Advanced D™ with Calcium provides a powerful dose of cholecalciferol (Vitamin D3) 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 D3. Dr Cannell’s Advanced D™ with Calcium orchestrates combined actions to make sure that optimal influence is present towards bone, muscle, and metabolic function.*

    Key CoFactors

    Dr Cannell’s Advanced D™ with Calcium features 5,000 IUs of Vitamin D3 plus a modest dose of well absorbed Calcium (citrate) balanced with key co-factors Magnesium Citrate, Biotin, Boron and an added provision of Vitamin K2 to fortify and support your bones and joints.*

    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. Calcium is the cornerstone to strong bones and muscles. 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™ with Calcium 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.*


    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™ with Calcium 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 and Muscles

    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™ with Calcium further support the skeletal and muscular systems.*

    Powerful Immune Support

    Vitamin D also has an interesting role as a regulator of the immune system. D3 has unique immune-modulating properties that can support health and wellness by supporting innate immunity. For additional support, Dr Cannell’s Advanced D™ with Calcium contains Zinc, another immune-supporting nutrient.

    Heart and Cardiovascular Support

    Recent research is increasingly pointing towards the importance of Vitamin D in maintaining healthy heart function. This premise of Dr. Cannell’s formulation is complemented by the Zinc, Quercetin and FruiteX-B® functioning as antioxidants, doing their parts in supporting the stability of cell membranes throughout the cardiovascular system.*

    • I was really amazed with the Vitamin D product by Dr. Cannell. I had heard an announcement on the radio and thought I would give a call to try the Vitamin D. They were right! You will want to continue to use the product. I was taking a vitamin D product I was getting from the vitamin store, but they were not as potent as Dr. Cannell's. I can definitely feel the difference. I love them.
