Yeah, I'm not too worried about this flu getting out of hand in my case (though last night I had a pretty bad fever). But I am worried about giving this to my father. He is 68, gets very sick whenever he catches anything, and he has a long awaited and planned for vacation coming up in July, which would be horrible to spoil with the flu. Truth unfolds in time through a communal process.
A useful dose for Vit D is 10-25ug/day. It's almost impossible to overdose on D - you'd need to eat an entire 90 capsule pack every day for a couple of months - so this is a safe basic intake.
You could try if you have symptoms and they're showing signs of getting serious.
