Vitamin D and PERFORMANCE

[OakLeaf]

So isn't cod liver oil a 'supplement' too? Is the vitamin D in it a hormone?

Well sure, and I only suggested that it might be useful for people who live in those latitudes where the sun only rises for 3-4 hours a day, or less, in the wintertime, at an angle where very little UV gets through. And people who have some type of absorption disorder, also.

Relying on supplements for anything is like saying "you don't need carbs from food, just eat plenty of refined sugar." Sure there are times in some people's lives when they need IV glucose, but it's not your first line of nutrition.

I'm the first to admit that I take a pretty high dose of a calcium/magnesium supplement whenever the weather's warm. I love greens, but there's a limit to how much I can eat, and I think a lot of US soils are deficient in those nutrients as well, particularly magnesium. (Time to put some more greensand on my garden I think. )
