How Much Vitamin D?

Apparently, the first few articles regarding Vitamin D have caused some resonance in those who have read them. Questions regarding how much Vitamin D should be taken daily – what form should be taken – and how do I know if I’m deficient have become quite numerous among my patient family. The curious thing is that everyone who has tested for Vitamin D – who have not been taking any form of the vitamin – has shown a deficiency state. When they began taking the form that I strongly recommend – an emulsified liquid form of Vitamin D3 – they have generally reached a sufficient state within 30 to 90 days.

So, generally, my strong recommendation is that you have your Vitamin D level checked as quickly as possible. Then:

1)    Take enough Vitamin D3 to get your 25(OH)D level above substrate starvation levels (50 ng/ml or 125 nmol/L).  Levels of 50 ng/ml usually require at least 5,000 IU per day for adults, some adults will require more.  Children should take 1,000 IU per every 25 pounds of body weight.  After taking this dose for 3 months have a 25(OH)D level. Individual variation in dose response is great and natural 25(OH)D levels (50-70 ng/ml) are not assured by these doses. I think it possible that Vitamin D levels of 30 ng/ml, which are often obtained by people taking low doses of Vitamin D (1,000 to 2,000 IU/day), may increase your risk of death from a 1918-like influenza virus.

2) Stock your home’s pharmacy with several fresh bottles of emulsified Vitamin D3,  a medicine, not a supplement, and if you get a flu, take 2,000 IU per kg (2.2 lbs) of body weight per day for a week.  As I weigh 220 pounds, I would take 200,000 IU per day for seven days if I thought I had an infection with a 1918-like influenza virus.
