Vitamin D Sustains the Balance of Calcium Levels

The maintaining of calcium levels in the blood is very important for the normal operating of the nervous system and for bone growth, and for the upkeep of bone mass.

Vitamin D3 Supplements

As it is not always possible to obtain vitamin D from exposure to the sun, the intake of vitamin D supplements is a practical way to guarantee adequate levels of this important guardian of the body.

  1. My last three blood tests are showing vit d at a 5, white blood cells high and blood in my urine.

    Can the low vit D be caused by something else going on?

  2. We got hit with the flu pretty hard this year. I have 2 little ones and a hubby. When strep came to the house, I thought I was going to lose it. I found an article online that claimed Vitamin D was better than a flu shot so I started doing some research (my kiddos got the flu shot by the way, it totally did not matter). I eventually got a book on it, “Powerful Medicine – Vitamin D” and I was totally blown away about how important this stuff is. You always hear about vitamin C, not D. I got my family on D and so far, no colds. Even when their cousins show up with snotty noses 😉
