Hey, guys, Dr. Burke here in this video. I want to talk about vitamin D and viruses.

Did you realize that 75% of all infections are viral? Interesting.

Vitamin D can reduce viral infections by 50%. And when you consume vitamin D, always consume it

in vitamin D3, okay? Taking 20,000 IUs will greatly improve a cold sore, all right? So you may

want to try that next time you get one. In the fall, people get the flu. Guess why? I believe it's

because the sun, you know, you don't have the sun from the summer and then boom, you become

deficient in vitamin D because vitamin D deficiencies will increase susceptibility to viruses and

make you more susceptible. We always talk about vitamin C for the immune system. Vitamin D is,

I think, even more important. Vitamin D will improve autoimmune conditions. Vitamin D

is a hormone precursor. It's almost like considered a hormone and it actually is a precursor to

cortisol. Cortisol is a stress hormone, but intimately involved in immune system function as well.

And that's why when someone gets any type of autoimmune or any type of infection,

they take steroids or prednisone because of that because it suppresses the white blood cell,

okay? So vitamin D can act as a broad spectrum antibiotic, a natural one. Also, if you add zinc

vitamin A and selenium together with vitamin D, I think you would have a great natural remedy

for viral infections. Thanks for watching.
