From the newletter, "As the H1N1 pandemic looms, it is heartening that Dr. Alexandra Yamschchikov and colleagues at Emory University conducted the first meta-analysis of randomized controlled trials of Vitamin D treatment of infections, concluding that significant scientific evidence exists to support further research of Vitamin D treating, not just preventing, infections like the flu. The only mistake I can see is that she confused activated Vitamin D and one of its analogs with Vitamin D.

Vitamin D for treatment and prevention of infectious diseases: a systematic review of randomized controlled trials. Endocr Pract. 2009 Jul-Aug;15(5):438-49.

If you have been taking 5,000 IU per day for several years, you know Vitamin D helps, but certainly does not prevent all respiratory infections. Because H1N1 may be deadly, besides taking 5,000 IU per day every day (1,000 IU for every 25 pounds of body weight for children) to prevent deficiency, make sure you have some 50,000 IU capsules of Vitamin D on hand this winter. "

I am looking into having the 50,000 IU dosage on had for this flu season.  I find this newsletter timely with all the discussion about vaccination that is going on here, there and everywhere.   Good to to have personal choices and alternatives if you might want one.

I will be interested in anyone who choses this route and ultimately the experiences in the long run.


Thanks so much for posting this. I have been taking extra D when I feel like I have an infection coming on. Sun exposure and/or pills--it has been an effective defense strategy. I also get the D newsletter and enjoy reading what Dr. Cannell has to say.

I am going to order this high dose D to keep on hand in case of a flu break out at my school. It's a very dangerous job working with all those sick kids when your immune system is compromised by Cpn.

I am not sure the vaccine will come out in time and I have reservations about taking it when so little testing has been done.


Feeling 98% well-going for 100. Very low test for Cpn. CAP since 8-05 for Cpn/Mycoplasma P.,Lyme, Bartonella, Mold exposure,NAC,BHRT, MethyB12 FIR Sauna. 1-18-11 begin new treatment plan with naturopath

Not to be taken daily!

I am a pharmacist and have done much research on this topic.  I have to warn against taking such a high dose of Vitamin D.  50,000 IU should definitely NOT be taken on a daily basis.  In fact the 50,000 IU dose is not recommended unless you are being advised and monitored by your physician.  Vitamin D overdose can be very serious and threaten your health.  The recommended dosing for Vitamin D DEFICIENCY is 50,000 IU is only once a week for 4 weeks, once every two weeks for 4 weeks, then once a month thereafter.  But again, you should speak to your doctor before beginning this regimen.  And definitely do NOT give this strength of Vitamin D to anyone under the age of 18.  Vitamin D2 50,000 IU is only availble by prescription, and in my opinion the D3 should be as well.
