EXCELLENT product, EXCELLENT COMPANY! I am SO impressed with my Naturewise experience. I struggle with mild depression and never wanted to spend much time in the sun as Skin cancer runs in the family, so I had to find another source of vitamin D. I've been taking their VitD3 for about four months now and really do feel like my levels have leveled off a bit and don't find myself falling into depressive states nearly as much. And, just as Naturewise points out (way to go not making the claim some companies do that the vitamins are the be all, end all cure), Vitamin D3 is necessary and helpful, but is MOST helpful when integrated into an overall health plan that involves exercise and good diet, which I have been doing as well. Thanks for the encouragement! Another thing I love about Naturewise is that their company isn't determined to charge as much as possible for their products. Instead of making a quality product to get as much money as possible, Naturewise seems to truly care about making quality products and getting them into people's bodies because they're passionate about seeing lives improve! ALSO, I spoke with them a while after using the product to learn more about their other products and tell then what I thought about the vitamin D, and they sent me a FREE 60count bottle of the vitamin D. WHAT?! Who does that?! Top knotch customer service all the way. I know I may sound overly enthusiastic, but I have worked in customer service and done quality control, so am very particular and hard to impress. NatureWise is a truly impressive company thru and thru. I'm someone that does a LOT of searching to find the right product and have hardly taken the time to review any products, but thought this one was worthy of the time. Stop researching and buy this product
