20 key bone building nutrients — an overview

Depending on how we count them, there are at least 20 bone building nutrients which are essential for optimal bone health — “essential” in that our bodies cannot manufacture them, so we must get them from our food and drink. Let’s take a quick look at them, one by one, so you can get a better idea of their roles in bone health and how much of each you should be getting.

Remember, none of these nutrients does its work in isolation — you need some of each and every one, so they can all work together to keep your bones standing strong all your life long. Taking a top-grade multivitamin–mineral complex and essential fatty acids will ensure that your cells have adequate levels of these nutrients ready at hand from minute to minute, day after day, to prevent bone loss leading to osteoporosis, other degenerative diseases, and accelerated aging.
