While I wholeheartedly agree that we need to look at the big picture and that a healthy diet is absolutely essential, supplements may still play an important role of support. Many of us led a healthy and active lifestyle and our bones still diminished with no known cause other than genetics. It really is important to look at your diet overall to determine the nutrient profile it provides and then figure out whether you need to supplement. Best to get your nutrients from food as much as possible and supplement as little as you need. When selecting a supplement, it is important to consider the quality and sometimes a good quality supplement costs a little more than some obscure brand you might find on Amazon. They are not necessarily the same. Certifications on products from NSF International and U.S. Pharmacopeia (USP) are a good thing to look for on the label to assure quality. Consumer Labs does lab analysis of many products to determine whether they actually contain the supplementation they claim and whether they exceed standards for lead and other contaminants. I am often amazed at what they find. You might have to pay a little more for a supplement that meets these high standards but in doing so, you know you are really getting what you pay for. That said, money spent on the best quality whole foods comes first and supplements secondarily only when needed.
