Thank you for your information, arthurus.
I will test your recommendation the next time I get the flu seeing I cannot take the shot. I am a big beliver in Vit. D-3 but I have never heard of this before.
If you take 10,000 units a day until you are wearing short sleeves again- 2 5k gelcaps, you shouldn’t have occasion to try the megadose. All it is is sunshine in a gelcap. Sunshine on your skin is what you are lacking in the winter which is why colds and flu are winter phenomena.
