And you're in Alabama. You're at a latitude where it's at least possible to make vitamin D from sunlight, year round.
I'm in New York. I supplement with vitamin D and I've posted quite a few articles favoring supplementation. But there are other opinions so I posted this.
Fair and balanced. ;-)
BTW, I take 4,000 IU of vitamin 'D' a Day. I haven't been sick once in three years.
