Holick's 40 year vitamin D journey

150 ng MS in Brazil is a real eye-opener (Holick visited Brazil in 2013)

OK to have levels up to 100 ng – just watch out for too much Calcium

           (VitaminDWiki: Reduce Ca, increase Mg, and take Vitamin K2)

Infrequent dosing is OK 2X per month and even possibly monthly,

Far better to publish his Psoriasis findings in the Globe (20,000 letters) than NEJM (Had been turned down anyway)

Before 1950 hot dogs, custard, etc fortified with Vit D around the world,

Bats not get vitamin D from the sun: vampire bats 255 ng, fish eating bats 245 ng, fruit eating only 24 ng

He uses 30 SPF sunscreen, but not on arms and legs

He and family gets about total of 3,000 IU vitamin D daily

He has 56 ng/ml

Endocrine Society recommends 40-60 ng

Chickens can generate 10X more vitamin D on portions of their body not covered by feathers

High school students are developing a UVB LED bracelet or belt

Comment from Audience 10,000 IU for 10 years not touch his RA 50,000 IU was great
