I have used Source Naturals Vitamin D3 for 3-4 years, started when a friend I work with had skin leasions and cause was diagnosed not getting enough Sun, He remedied this with his DR.'s advice by going to the tanning salon and using Vitiman D, I have light skin with freckles and some ocasional slight skin problems and decided it would do no harm and may prevent problems, it seems to be working, I purchased this from Amazon seller because it is exactly what I had been using, was looking for, and offered at a good price, I will be looking up seller again when I need more.
NOW Vitamin D-3 softgels supply recommended levels of this key vitamin in a highly-absorbable liquid softgel form. Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. However, it is not abundant in food. As more people avoid sun exposure, Vitamin D supplementation becomes even more necessary to ensure that your body receives an adequate supply.
