Vitamin D: Why It's So Important

Posted at 11:00 - June 14th, 2019 - Megan & Jae - Education Guides

One scientist's personal story

Biochemist Paul Stitt watched as his son deteriorated. By the time his son reached the age of 37, his debilitating pain-ridden osteoporosis was severely limiting his quality of life. It began when he was young with a fall from a bicycle. The accident left him with a broken hip. By the age of 24, Paul's son was diagnosed with osteoporosis.

Paul compiled 40 years of scientific data on Vitamin D deficiency looking for answers to help his son. He discovered clues linking lack of Vitamin D with pain and bone deterioration. Initially, this was a puzzle because his son had grown up on a Wisconsin dairy farm drinking milk and getting sunshine every day. So how could he be Vitamin D deficient?

Maybe it's time to look at the “real story” regarding our need for Vitamin D.

What are some of the most common indicators of Vitamin D Deficiency?

Obtaining Vitamin D

Vitamin D receptors are Contained in every tissue in body


Required for

Cardiovascular system

Bone health

Teeth & gums

Cancer prevention

Pain relief

Prenatal & neonatal health

Arthritis prevention & treatment

Immune function

Depression management

Option 1: Exposing skin to the sun

  • Amount of Vitamin D produced from sunlight: Dependent on time of day, location in the world and how much skin is exposed
  • Body's ability to produce Vitamin D is essentially non-existent in winter climates (north of southern Florida) even if skin exposure could be tolerated


Option 2: Food

  • Foods containing Vitamin D (beef liver, fish, egg yolks) do not supply enough
  • Vitamin D is found in the fat of fish, which is the part most people don't eat
  • Even fortified* milk accomplishes nothing because the Vitamin D is not absorbed (according to FDA studies)


Option 3: Taking Vitamin D supplements

  • Vitamin D Council: Now recommending 5,000 iu's daily for most adults
  • Potential for toxicity has been greatly overstated: People in sun-dense environments generate over 19,000 iu's per day


Evidence indicates Vitamin D is made on the surface of the skin

Absorption from the skin surface may take up to 48 hours

Most people shower within 48 hours of exposure which interferes with absorption of Vitamin D



* fortified refers to milk that has had synthetic vitamins introduced into it after it has been pasteurized. Pasteurization occurs at approximately 180 degrees which results in destruction of most of the enzymes and nutrients present in raw milk.

The Message in Pain

  • University of Minnesota, 2008 study: 93% people of people with ongoing chronic pain (specifically Fibromyalgia and MS) had severe Vitamin D deficiency
  • The Switzerland Study, 2010: 10,000 iu's/day of Vitamin D, over 1-3 months, resolved the majority of chronic pain issues in the participants studied
  • American Journal of Clinical Nutrition, 2009 study: Increasing daily Vitamin D intake from 400 to 2000iu’s improved insulin function by 60% (higher than results from anti-diabetes drugs)
  • University of Medicine, Vienna, 2008 study: Deficient Vitamin D was linked to colon/breast/prostate cancers, chronic inflammatory/autoimmune diseases (including diabetes) and metabolic disorders

Additional Research Indicators

  • Multiple Sclerosis patients show extremely low Vitamin D levels
  • Low levels of Vitamin D contribute to a dramatic increase of PMS
  • Muscle weakness is frequently indicated as a symptom of Vitamin D deficiency
  • Vitamin D is a hormone which directs the immune system to attack invading bacteria
  • The FDA admits: Preventing autoimmune diseases requires adequate Vitamin D
  • Vitamin D deficiency has been linked to greater risk of cancer, osteoporosis, humped-back shoulders, diabetes and death from cardiac issues
  • Chronic pain has been linked to Vitamin D deficiency

Note: All references to Vitamin D are the natural form which is D3. D2 is synthetic and not bio-available

“Every ‘disease’ has a biochemical cause and once you fix the cause of the problem, the ‘disease’ will go away. This is what we biochemists were taught at the university. It really does work.”

Author/Biochemist Paul Stitt

Basic Dosage Guidelines (Vitamin D Council)

  • Infants: 1000 iu's per day
  • Children: 1000 iu's per 25 lbs of body weight
  • Adults: 5,000 to 10,000 iu's depending on specific needs
