In a Nutshell

Osteoporosis stems primarily from magnesium deficiency, which impairs calcium regulation, vitamin D activation, and parathyroid hormone function, leading to bone loss even when calcium levels are normal. Taking calcium alone can worsen the problem by depositing in arteries or kidneys instead of bones. The fix requires therapeutic magnesium (300–400 mg glycinate, 3x daily), high-dose vitamin D3 (≥20,000 IU) plus K2 (40–45 mg), adequate protein, weight-bearing exercise, and stress reduction.

Taking calcium can actually make osteoporosis worse. If you have osteoporosis and you're taking calcium, you may actually be making your bones weaker. Not because calcium is bad, but because of a misunderstanding of how bone really works and how calcium can go in the wrong place if certain things are not set up correctly. Patients are told to either take calcium or calcium with vitamin D to correct this problem. In fact, some people that take calcium even end up with kidney stones and hardening of the arteries.

Osteoporosis is not a calcium deficiency because bone is not just a calcium storage unit. Bone is a mineral bank for most of your phosphorus and over 50% of your magnesium. Magnesium is the key to understanding this whole story. Magnesium controls calcium. It tells calcium where to go and where not to go. Magnesium even allows vitamin D to work. Vitamin D cannot work without magnesium. It's dependent on magnesium.

One major cause of osteoporosis is when your parathyroid hormone, a hormone made by your parathyroid glands, goes into the bone and robs it. It takes this storage of calcium out of the bone and puts it in the blood. If the parathyroid gland is overworking over a longer period of time, that can create osteoporosis. Excess parathyroid hormone can come from low vitamin D because you don't have enough magnesium or you're just not taking enough vitamin D. Even if we just take away vitamin D, if you're low on magnesium, the parathyroid hormone can't work because it's dependent on magnesium. This is just another reason why a magnesium deficiency can cause osteoporosis even more than a calcium deficiency can.

People are taking calcium, they have normal calcium, yet they have severe osteoporosis because bone density does not equal bone strength. When magnesium is low, you lose calcium because magnesium controls calcium. The arteries can harden because now there's no instructions of where that calcium should go. You could be more susceptible to kidney stones. One of the best preventative things you can do or even antidotes for kidney stones is to up your magnesium.

When you get a blood test, it's very easy to detect calcium and phosphorus, but magnesium is very difficult to detect because the majority of magnesium is deep inside the cells, not in the blood. It's hard to know if you're really deficient in magnesium. The bone is a mineral bank and so it actually stores a lot of these minerals and so it will give up these minerals if the body needs to use them. A lot of times you don't detect a magnesium deficiency until late in the chain of events.
