Re: good summary of both sides of the issue on D...

still fairly clear you simply don't understand the studies posted. If I thought you honestly cared to understand this, I might engage in a longer conversation.

Re marshall, I quote him because his studies on the Vit D pathways in the body are groundbreaking and correct, so, why throw out the baby with the bathwater. So his protocol is bad, that does not mean his understanding of the problem is wrong. Take the good and build on it.

regarding other nutrients, you can't make the same anology to vitamin D, which is far more complex, and in fact, acts in the body like a hormone, not a vitamin or mineral... so your question seems rather pointless.

regarding the heliotherapy, perhaps if you posted an actual study rather than annecdote, it might enable me to actually respond. just a thought.
