@leeosteo No direct experience, but remember that direct-promotion supplements are often many times more expensive than mass market supplements.

If I was in the market for additional supplements, first I would compare the ingredients in an adult daily vitamin and mineral supplement to the ingredients listed on the label of the "bone-building" supplement. Chances are you will find most of them in the daily supplement. Then I would compare the cost of the calcium/vitamin D, etc at the drugstore to their brand. Finally, I would look for independent, scientific evidence that the long list of herbs included have been clearly demonstrated to help rebuild bone.

All of the vitamins, minerals and herbs used by all reputable supplement manufacturers come from just a handful of sources, so they should be equally effective no matter the brand.

Keep in mind that with supplements, as with many things in life, more is not always better. Excess vitamins and minerals, at best, are excreted through your kidneys as expensive pee. But, sometimes these substances can exacerbate other conditions, interact with medicines you take, cause side effects, or build up to unhealthy levels in your body.

Finally, bone building is a combination of diet, exercise and medication or supplementation. The stool falls down if you miss any leg.
