A 2014 study indicates that glucosamine supplements aren’t likely to work well if you’re deficient in the trace mineral boron.By now, lots of studies have verified the ability of glucosamine supplements to relieve the pain of osteoarthritis (OA), often better than over-the-counter anti-inflammatory pain relievers (although it takes longer for glucosamine’s effects to fully kick in). And unlike these drugs, glucosamine, a natural molecule found in most body tissues, can be taken safely long-term. Also unlike drugs, glucosamine goes way beyond symptom relief: It’s been shown to inhibit joint deterioration and to stimulate and support joint healing and repair. There’s only one problem. Glucosamine supplements don’t always work. This leads many people to give up on them and go back to pain-relieving drugs that provide more reliable relief.Why don’t they work?Well first, there are vast differences in glucosamine quality. Glucosamine is an expensive ingredient, and its popularity has prompte…

Raymond Francis often says, “If you are deficient in only one nutrient, you will get sick, guaranteed.” Although many people still focus single-mindedly on calcium, bone-building is a team sport. While calcium may be the star player, it’s ineffective and even dangerous without its teammates. If even one member of the team goes AWOL, your bones will suffer. Bones are about half mineral and half protein. Minerals give bones their hardness—an important quality if you want to stand up straight. However a large part of bone consists of “bone matrix:” flexible tissue made of collagen and studded with hard minerals. Calcium accounts for about 64% of bone’s mineral content, but phosphorus and magnesium also contribute to bone hardness. Zinc, manganese, silica and copper are used as co-enzymes in constructing bone matrix. Vitamin C is needed to create collagen. Vitamins C, D and K and the minerals boron, chromium, germanium, selenium and vanadium play various roles in what’s called bone…
