This is the best bone building supplement i have found. Started taking while healing a badly broken arm. Within a month of starting these my bone remodeling showed up in xrays as way faster than it had been going and surpassed what my surgeon expected. I would recommend to young and old to prevent fractures, gals the bone you build in teens and twenties will make a big difference in what you have as an elder,. Very importantly it has the type of calcium and supplements that deposits the calcium into the bone, not in soft tissue like arteries. Taking most forms of calcium supplements increases Heart attack risks so you need to supplement wisely Just three a day and they though large don't stick in my throat the way many pills or caps do. i highly recommend. Using these i've grown bone to bridge a very bad non joined break before 6 months, not expected to do so,by surgeon so i will need to have all the metal placed there, the bone is pushing away the plate. I should i'm told be able to do anything i could do before the break with my arm and hand. It's worth the cost, wish i had discovered it long ago. Buy some for your mom as well as yourself to keep her bones stron
