"I started taking this vitamin D3 by Natural Factors a few years ago because my vitamin D level was very, very low and I was unable to tolerate the Rx dose. I have serious digestive tract problems, but, thankfully, I am able to process and absorb this vitamin D3. Both my husband and I take products by Natural Factors with excellent results. Today my vitamin D levels are normal and soon I will be able to begin osteoporosis injections. I appreciate the needed results of this dry D as I cannot tolerate or process the liquid forms and I highly recommend Natural Factors Vitamin D3 to anyone especially if they have GI Tract problems."
