I’ve mentioned before, but I’ll say it again. You can all get a prescription from any doc for vitamin D. What the pharmacy will give you is very likely better quality than whatever you’re buying at the supp shop. I got a script for 10000 IU/ week and my Insurrence covers the cost.
Personally, I don’t take them throughout the summer. I’ll double up through the winter months
Vit d is so cheap to make and most people are deficient in it. It is actually classified as a steroid.
I've read somewhere that it synergizes well with vit k for calcium/ bones and it's used in the formation of cholesterol.
I would easily say one of the most overlooked vitamins.
