What is Vitamin D?
It seems that a day does not go by without hearing about Vitamin D. So, what is Vitamin D?
Vitamin D is a very complex substance. For over half a century vitamin D was thought only to mineralize bones. But studies indicate that it does much more:
• Regulates calcium in all cells (especially brain cells)
• Protects the immune system
• Regulates cell growth and cell death
• Provides antioxidant and antiviral benefits
Since foods contain very little vitamin D, the body’s major source is from that manufactured in the deeper layers of the skin. The UVB wavelength from sunlight activates 7-dehydrocholesterol (7-DHC), transforming it into a precursor form of vitamin D-3.
It then changes to active vitamin D-3 and enters the blood stream where it is distributed all over the body.
Vitamin D from foods is metabolized in the liver and the kidneys to form the active vitamin D-3. Many forms of commercial vitamin D supplements are not the active form. So, when you buy vitamin D supplements make sure it is vitamin D-3.
Bob’s Best Vitamin D3 is the active form and very beneficial to the body, providing 5000 iu of Vitamin D3 with each tablet. Bob recommends that you use one of his vitamin D3 tablets and one coral calcium with each meal.
