When Advanced D^™ was formulated, we consulted Dr. John Cannell, M.D., the Executive Director of The Vitamin D Council. Dr. Cannell insisted on 3 very important things:

1. 5,000 IU of Vitamin D3
2. Co-Factors to support Vitamin D absorption, activation, and core benefits
3. Extra Immune Support from Zinc and Quercetin*

Vitamin D3 is the potent and bio-accessible form of Vitamin D — and 5,000 IU per day was shown to be more effective in raising and sustaining blood level concentrations of Vitamin D when compared to a lower dose.¹

Furthermore, Vitamin D is more effectively absorbed and utilized when coupled with certain key co-factors:

• Vitamin K2 partners with Vitamin D3 to ensure that calcium gets inside your bones instead of your arteries.
• Magnesium assists in the activation of Vitamin D3.* Magnesium is another nutrient that has an alarming deficiency rate among Americans.
• OptiZinc^® + Quercetin provides critical immune system and antioxidant support to complement Vitamin D3’s role in immune cell response.*
• FruiteX-B^® PhytoBoron is a patented boron/calcium complex. Boron has been shown to help the body maintain optimal levels of vitamin D*.
• Taurine is an important amino acid that plays a role in cardiovascular function and muscle response, making it the perfect companion to Vitamin D3’s role in these two key areas of health.*

The importance of maintaining healthy blood levels of Vitamin D cannot be understated. While people have come to think that a glass of milk and a little sunshine will fulfill their Vitamin D needs, the deficiency numbers prove otherwise.

And as we have seen, when taken alone, Vitamin D does not carry the full effect that it does when surrounded by key co-factors in a balanced formula.
