24:00 “A black individual would need to be in a sun tanning bed probably more than ten times longer to make the same amount of vitamin D.”

26:00 Aging: “A 70-year-old will make about 25-30% of vitamin D that a 20-year-old will make.”

28:00 Toxicity: Canadian study showed taking 20,000 iu/day no toxicity and 60-80 ng/ml: “We did a study with a group up in Canada, and showed that taking up to 20,000 units a day, blood levels with 60-80 ng/ml; there was no toxicity.”
100,000 iu/day for extended periods can cause toxicity.

Holick takes 6,000 iu/day year-round with 70-80 ng/ml.
Says to keep taking D in summer.

34 Breast milk has “no” vitamin D unless mother has enough D, about 6,000 iu/day.

C-section reduced with enough D.

38 2,000 iu for infants shows less type 1 diabetes

39 Study: Immune system improvement, cancer, DNA repair effecting gene expression:
600 iu/day = 150 genes affected
4,000 iu/day = 300 genes
10,000 iu/day = 1,200 genes

Most can’t get enough D from sun in summer — unless life guard.

44 This amount Hollick says here seems too low compared to what he says in the rest of the video:
He recommends patients taking 50,000 iu every two weeks (3300 iu/day) after attaining sufficiency by taking 50,000 iu every week for two months reached 80,000 iu. Yet Hollick says he personally takes twice this much and gets 72 ng/ml results (in other videos) and 70-80,000 (in this video), and he’s much thinner than the average person who would need to take more D to get to that same 72 ng/ml number. At minute-39, he says 10,000 iu/day was far better than 4,000 for immune system improvement and DNA repair. He also says here that those who are obese, on certain meds (anti-AIDs meds, anti-seizure meds, steroids), pregnant or have a rare disorder, these need to be tested to make sure they’re getting enough. In some videos, Dr. Hollick says obese people need two to three times the amount of D, and a large percentage of Americans are either overweight or obese. 

Sunshine also gives nitric oxide, beta endorphins, ACTH, CO (said earlier)

Altitude in November in Agra India: Taj Mahal, no D; at 5,000 meters, lots

“In my opinion, there should be no reason not to get some sensible sun exposure for overall health and well being.” “…minimal risk, and a lot of upside to improving health and well being.”
