What’s the D’eal with Vitamin D?

One of my personal passions is micronutrient optimization. So many of us are deficient due to dietary choices, malabsorption issues with our intestines or, simply the aging process. One of the most important vitamins is Vitamin D (which is actually a hormone!).

So what does Vitamin D do for us?

The role of Vitamin D in our health is huge. This hormone enables our cells to communicate. Without sufficient Vitamin D levels, our cells cannot speak to one another efficiently which creates a myriad of health problems. Here’s a list of the diseases Vitamin D optimization could either cure or reduce by percentage, as stated by the Vitamin D Society (4).

  • Rickets, reduced by 100%
  • Osteomalacia, reduced by 100%
  • Cancers, all combined, reduced by 75%
  • Breast Cancer, reduced by 50%
  • Ovarian Cancer, reduced by 25%
  • Colon Cancer, reduced by 67%
  • Non-Hodgkins, reduced by 30%
  • Kidney Cancer, reduced by 67%
  • Endometrial Cancer, reduced by 35%
  • Type 1 Diabetes, reduced by 80%
  • Type 2 Diabetes, reduced by 50%
  • Fractures, all combined, reduced by 50%
  • Falls, women reduced by 72%
  • Multiple Sclerosis, reduced by 50%
  • Heart Attack, men, reduced by 50%
  • Peripheral Vascular Disease, reduced by 80%
  • preeclampsia reduced by 50%
  • Cesarean Section, reduced by 75%

Basically, everyone who doesn’t practice regular full-body skin exposure without sunscreen is deficient. The great thing about sunshine acquired Vitamin D production, is it equals about 10,000u and it lasts 2-3x longer than vitamin supplementation. However, dermatologists have made us paranoid about sunshine exposure. We should never sit in the sun to burn but allowing our skin to soak up the sunshine is not harmful. Just use caution to not stay out there long enough to burn.

Winter bringing you down?

Here’s another happy fact. A randomized double-blinded study (this is the gold standard of research) found that people who have higher Vitamin D levels suffer less from SAD (seasonal affective disorder) or winter depression (6).

So how much do the experts recommend?

Optimal vales by the preeminent experts are recommended to be between 40-60ng/ml according to 40 of the top Vitamin D researchers (4)

First, get your level tested by your physician. Supplementing without knowing your baselines values isn’t a good idea.  Research has shown that supplementing with 4000iu Vit D3 daily has been found to be very safe.  The experts,  Dr. Reinhold Vieth and (5) and Dr. Michael Holick has been studying the effects of Vitamin D deficiency their entire career and many of their lectures can be found on Youtube (2,3).

Baby, we all need it!

Good health begins at birth. By taking care of our bodies from the beginning we have the opportunity to live long, and vibrantly healthy lives. In a study by researchers Dr. Bruce Hollis and Dr. Carol Wagner, it discussed the role of maternal Vitamin D supplementation and the infants level of Vitamin D. The study concluded that breastfed infants need to be supplemented with 400iu of Vitamin D3 daily AND the Mother needed to supplement with 6400iu a day in addition to her prenatal vitamin. Once again I have to say…never give your baby anything before clearing it with your pediatrician! 

Water and sunshine are live-giving…we wouldn’t survive in the dark for long. Our bodies need sunshine for so many reasons so get out there in nature and go check your Vitamin D levels! Optimize your health, to optimize your life.
