(Amazon wouldn't let me leave a review on this product so came here to post.)
This is a wonderful product! I've been battling low bone density for 15 years. 2 years ago it was at it's lowest range 29 . I had a total knee replacement surgery to start preparing for. I started taking this supplement last year and was able to get my bone density to a 50! I was able to proceed with my total knee replacement and I had no complications. I believe it is because of this wonderful product. My MD said for me to continue taking. It appears to be highly absorbable and the first D3 supplement that works for me. I highly recommend to all my friends and family.
