Okay, I’m sold. But how much should I take? And is there a certain brand or type of pill that is better?

There is no consensus or agreement on how much or what.
An early study found that 2000 iu/day prevented flu in hospital inmates where most of the others got flu.I followed the original study as reinforced by the good doctor Dr. Rosenfeld on Fox, 2000 iu regular, 4000 when flu is present in the population.
I bought 1,000 unit tabs at Walmart where they are cheap. The next time they were selling 2,000 unit tabs. Most recently they were selling 2,000 unit gelcaps. That means they are very much on to the trend and some higher effectiveness is perceived for the gelcap that is the Americans always seek to optimize to the max and I think that is case here.
If you do a little online research there is a ton of stuff in the last two years. There are many threads here on Free republic where I first learned about Vitamin D3.
