When Advanced D™ Men's Formula was created, we consulted Dr. John Cannell, M.D., the Executive Director of The Vitamin D Council. Dr. Cannell insisted on 4 very important things:

1. 5,000 IU of Vitamin D3
2. Co-Factors to support Vitamin D absorption, activation, and core benefits
3. Extra men's health support from Zinc*
4. Support for healthy testosterone levels from Boron*

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 (as MK4 and VitaMK7^®) 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 and clinical research shows it supports healthy terstosterone levels.*
• 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.*
