I was diagnosed with a pretty bad vitamin D deficiency after a recent bloodwork after being diagnosed with Multiple sclerosis. I have not been the most active person due to the symptoms of this immune condition. I have tried several kinds of "Their" (when i say "their" I am talking about the sometimes intimidating doctors) vitamin D prescriptions and neither of them were my favorite. They did the job of increasing my Sun levels in my blood but came with UNPLEASANT symptoms....... i.e. .... bloating, stomach aches and frightening trips to the bathroom that left you regretting eating at all. This all lead me to trying an OTC supplement .... I tried another brand at first and it actually raised my vitamin D levels quicker than the Drs version :-) ....... but then I began to notice that My bones were hurting still, I was still feeling weak and falling as well. I can't blame that on the vitamin d from before because ... after all.... I DO in fact have Multiple sclerosis... A friend mentioned an article about how some of the supplements were grown and tended to. I decided to try something new. I wanted to try something green in theory. I have read about how an organic life and eating can effect my condition...SOoo... why not my supplements as well right? ... After trying this brand... at first I wasn't paying attention but after a few more days... I realized that I was walking around my apartment without hearing the agonizing dragging sound of my foot on the floor... :-) ....Well.. it did not stop completely but it decreased quite a bit. I never experienced this with the previous brand including the pharmaceuticals ... I also realized that I was not as exhausted as well. ...... OH .. and my teeth.... My teeth were beginning to suffer. They were becoming translucent. Since the change... they are looking better. In short... I am feeling really good! I am a new fan. The moral of my story? ...... These softgels were a very good swap. They are a tad bit bigger but that isn't a problem at all for me. The price was a little higher than the other brand but the bottle has more softgels and the price was still less than two bottles of the other brand. I would definitely suggest them as a brand to give a try. I also purchased another of their supplements. My second shipment arrived with a paper that had instructions for receiving a free bottle of the supplements that I had purchased. That was pretty awesome and sweet of them
