Vitamin D3  Vitamin D, or the sunshine vitamin, is essential for our all-round well being, aiding in several functions from bone strength to calcium absorption and boosting immunity. It is the one vitamin that also functions as a hormone, or chemical signaler.

It’s called the sunshine vitamin because our bodies produce it when exposed to the sun. Unfortunately, these days many of us are Vitamin D deficient because of our sedentary and largely “indoor” lifestyle – and this can lead to a slew of health complications.  

It is important to know your vitamin D3 level, high or low it matters.
