Vitamin D

I had my website reviewed and I got high remarks. woot woot. Okay, back to being serious. Vitamin D is worth it to be studied in the blood. it should be measured for more scientific studies. Many diseases are connected to Vitamin d deficiency (i.e. breast cancer, colon cancer and kidney...etc.). Side note: why is Vitamin D called vitamin D? isn't it a hormone? Anyways Vitamin D is almost an uncharted land or sea, there is not a lot of relevant reliable data and info. Almost all data and info is circumstantial and heavily biased whether it be for or against.
