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
  Trust Your Gut: Get Lasting Healing from IBS and Other Chronic Digestive Problems Without Drugs
  April 2013, very little about Vitamin D
• 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
