Why is Vitamin D so Important?

Vitamin D.  

Technically, it’s not really a vitamin.  It’s in a class by itself.  The active metabolic product of Vit D is 1,25 dihydroxy vitamin D, Vit Da secosteroid hormone.  Every cell in the body has a receptor for it and it affects over 1000 genes.

Vitamin D deficiency is a big problem.  It’s found in all ages and is especially prevalent in African Americans.  36-57% of Americans are Vitamin D deficient [1]

Vitamin D is critical for good health and protection from disease.  Healthy serum levels are in the 30-105 ng/ml range.  It’s a myth that you can get adequate amounts with 15 minutes in the sun every day.  You cannot.

Here’s why Vitamin D is so important.  It reduces your risk of:

  1. Cardiovascular disease and heart attack[2]
  2. Cancer, including colon, breast, ovarian and renal [3][4][5][6][7]
  3. Falls in women (neuromuscular control)
  4. All fractures[8]
  5. Multiple sclerosis[9]
  6. Non-Hodgkin’s lymphoma[10]
  7. Type 1 diabetes
  8. Contraction of influenza[11][12]
  9. Alzheimer’s disease, dementia[13]

How to supplement with Vitamin D:

First, choose a pharmaceutical grade brand such as Metagenics or Xymogen.  Note that each 100 IU of Vit D3 intake increases serum 1,25(OH)D by 1 ng/ml[1] over the course of several months.

I take 5000IU of D3 daily for maintenance of healthy serum levels.

Go to Metagenics Store to find medAge-approved Vitamin D supplements.
