Yes, I’ve been taking BoneUp for over 20 years. A government study shows it improves bones significantly more than other types of calcium. I also take vitamin D, which is essential for calcium to be processed in the body. If your DEXA results indicate bone loss, my question would be: are you taking the 6 tablets necessary to get the 1000 mg of calcium? Two capsules should be taken 3 times a day. I’ve had osteoporosis since the late 90’s. This calcium works. Also, when I saw the most improvement was when I first started “Bone Builder” classes. These are very slow weight bearing classes created by Tufts University - you can find some videos on YouTube.
The bottle is misleading because it mentions 2 capsules per serving (above the nutrition box), but elsewhere it does say “Adults take 2 capsules 3 times a day (for a total of 6) with meals to facilitate maximum absorption.”
Hope this is the issue you have and taking the required amount will improve your bone density.
