I was told by a family member to buy the Vitamin D3 liquid vitamin from Wellness Market. I purchased it online which I found was easy to use. I had the item delivered and next day it was at my house! Great service and I already feel the difference since I began taking the vitamin. My bones don't feel achy at the end of the day and I don't feel anxious. I feel good. I can see why they call this the sunshine vitamin.
