Good to know, we have been on D3 a little more than a year now.
Interesting, thanks TG.
MANY thanks to you, STAR!
I get a prescription vitamin D3 not D2.
(Importantly, a small percentage of people get ill consuming even a small amount of Vitamin D supplement, as little as 3000 IU. And another small group of people cannot effectively absorb or convert Vitamin D supplements into serum (blood) Vitamin D. But most people can both consume and digest Vitamin D supplements in much higher doses.)
In February of 2009 a study found an inverse relationship between a person’s level of serum 25-hydroxyvitamin D and a recent bout with a cold or flu.
“Those who had recently experienced an ILI or other respiratory illness, were more likely to have lower than normal Vitamin D levels. The median serum level of 25-hydroxyvitamin D, among more than 18,000 people tested, was 29 ng/ml.
“Those with a serum level below 10 ng/ml (considered very low), were 40% more likely to have had a recent respiratory illness than those with a serum level above 30 ng/ml. The link between Vitamin D levels and the risk for respiratory infections was stronger in those with asthma or COPD.”
PLoS One published a study that strongly suggests that raising the blood serum level of Vitamin D to over 38 ng/ml could result in a significant reduction in viral respiratory illnesses.
Serum 25-Hydroxyvitamin D and the Incidence of Acute Viral Respiratory Tract Infections in Healthy Adults
James R. Sabetta, Paolo DePetrillo, Ralph J. Cipriani, Joanne Smardin, Lillian A. Burns, Marie L. Landry Research Article, published 14 Jun 2010 doi:10.1371/journal.pone.0011088
“Concentrations of 38 ng/ml or more were associated with a significant (p<0.0001) two-fold reduction in the risk of developing acute respiratory tract infections and with a marked reduction in the percentages of days ill.
“Maintenance of a 25-hydroxyvitamin D serum concentration of 38 ng/ml or higher should significantly reduce the incidence of acute viral respiratory tract infections and the burden of illness caused thereby, at least during the fall and winter in temperate zones.
“The findings of the present study provide direction for and call for future interventional studies examining the efficacy of vitamin D supplementation in reducing the incidence and severity of specific viral infections, including influenza, in the general population and in subpopulations with lower 25-hydroxyvitamin D concentrations, such as pregnant women, dark skinned individuals, and the obese.”

Thanks. I’ve been taking Vitamin D3 as a supplement, because it’s what the body produces from sunshine. I think it’s especially important to take it in the winter or when it’s overcast—often both.
You don’t need a prescription for it, unless it’s cheaper for you under your insurance plan. Or unless Obama changes the rules on supplements, as he has threatened to do.
Interesting. Thank you!
I heard this a long time ago, get D3. Because it’s the form your skin makes.
And it’s almost impossible to overdose on it. 15-20 minutes of noon exposure on bare skin will have the body produce 50,000 IU of vitamin D.
Better yet, the body uses cholesterol and converts it to vitamin D3. Sun exposure was designed to reduce cholesterol levels and increase your immune system by building vitamin D.
1. MD’s don’t ever seem to ask their patients about vitamin D, which cures and prevents so many illnesses. Each doc should test each patient no matter what his complaint.
2. If they ever do prescribe vit D, it’s the wrong kind.
Sometimes traditional medicine is soooo frustrating.
No surprise.
