Webinar by Dr. Greg Plotnikoff, Vitamin D Webinars by DiaSorin 2013-2014

  • Vitamin D is a Nature Deficient Disorder

  • Safe sunning, no burning

  • Rickets making a comeback – Plotnikoff asked viewer to guess which year

  • IoM in 2010 lowered 30ng ==> 20 ng, but tripled recommend amount for elderly

  • Cutting edge research in Vitamin D Binding Protein

  • At least 1,000 KEY genes controlled by Vitamin D

  • 5 current controversies

  1. Who has the normal level of vitamin D: office workers, lifeguards, farmers

  2. What is sufficiency. So far they just use the index diseases : generally short incidence (ignore lot latency diseases)

  3. JAMA: 1940 2 paragraphs in a paper noticed that there was 400 IU of vitamin D in cod liver oil

    • That became the standard for the next 70 years

  4. 15 minutes in the sun – latitude issues, clouds, haze (Hong Kong down 20%)

  5. Skin Color

  • His study: >40 ng would have save $2.5 million by increase presentment in just one workplace
    • The study included Health professionals, insured, etc yet still very low levels of vitamin D

  • BMI is increasing – which lowers vitamin D levels

  • Vitamin D is a fat-soluble vitamin, but body clears it – homeostatic protection mechanisms

    • 60 ng should be not harmful – we have had 10,000 generations out in the sun

  • Calcium absorption increases by 65% when vitamin D level raised 20 ng==> 30 ng

  • WHO has stated that only need 500 mg Calcium for vitamin D replete women

  • Denominator dispute with IoM about how many cadavers need 20 ng vs 30 ng of vitamin D

    • Even the author of cadaver paper disagreed with IoM, felt than 30 ng was needed

  • $40 million diabetes trial – Plotnikoff thinks it will be a good trial

  • Tanning booth were originally Vitamin D booths (statement by VitaminDWiki, not Plotnikoff)

  • Why not be sure your are sufficient if you are having any medical emergency/concern

  • Chronic non-specific pain reduced with vitamin D– his publication – the biggest in MAYO ever?

  • Hypothesis: Statin blocks cholesterol needed to make Vitamin D

  • He has authored a book: Trust your gut

  • No one dose fits all: 600 a day vs 6,000 a day

  • Need a test. By example, cannot tell Cholesterol or other levels by just looking at at a patient

  • RA also varies with latitude

  • Not get vitamin D from food: Are you going to eat 60 eggs a day – I don’t think so

  • Good dose of vitamin D for entire pregnancy would cost less than $5

  • Vitamin D2 had been used to escape from concerns about D3 toxicity (is this true?)

  • His own FAMILY requires more vitamin D: ethnicity and genes

  • 1/3 of herbal medicines from East Asian used to have sun-exposed mushrooms

    • Herbal medicines used to have has lot of vitamin D
    • however now the herbal medicines are prepared in ovens
  • Upstream levels of vitamin D can be normal – but local regulation is unknown clinically
    • So just testing will not ensure that all cells get access to vitamin D

  • Mental Health and vitamin D – looks promising

  • Perhaps Vitamin D also important in Gluten-free – similar to gut problems

  • Vitamin D level of farmers and lifeguards is much higher than IoM level
