- 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
- Who has the normal level of vitamin D: office workers, lifeguards, farmers
- What is sufficiency. So far they just use the index diseases: generally short incidence (ignore lot latency diseases)
- 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 - 15 minutes in the sun – latitude issues, clouds, haze (Hong Kong down 20%)
- 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

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
