What's the evidence on Calcium and Vitamin D for bone density?

After taking one Prolia shot, I could not walk more than a few steps for months. It was like learning to walk all over again. I refused to take any more of the shots as a result of all the issues I encountered after only one. I think this is a dangerous drug.

I live in sunny California and I am a gardening fool - I almost spend more time outside than I do inside. My vitamin D level was at 3 when I got tested about a dozen years ago - despite all that sunshine. Researchers claim there is too much particulate in our air and it prevents us from getting the full vitamin D experience we need. I began taking vitamin D3 and got my level up to between 80 and 90 ng/ml, and this has improved my health in so many ways and very dramatically. I have talked to many women who have done a ton of weight-bearing exercise and they all said it did not one thing for their bone density. A close friend who is a doctor and a long-distance runner told me she honestly believes it is worthless where bone density is concerned. As I have said many times here, I think the best thing is to EAT your calcium. If you can't eat enough calcium daily, then you might want to supplement. I take a food-based calcium; there are many brands of food-based calcium on the market, including Garden of Life, Rainbow Light, New Chapter, and more. AlgaeCal currently has been found to have lead in it and also only has 87% of the magnesium they advertise on the label. I also take Vitamin K2 (MK4 and MK7), magnesium, boron, vitamin C, a food-based multivitamin, and I have some collagen from grass-fed cows. You need the K2 to tell the calcium to go to your bones - otherwise it can pile up in your arteries or contribute to kidney stones. I have posted several websites that talk about vitamin K2 - you can do an internet search and find a lot to read about K2. The MK4 and MK7 varieties of K2 are easily absorbed by the human body and do different things - you want a K2 that has both. My DEXA scan was -5.7, so I am trying as hard as I can to get some bone growth. I am taking Human Growth Hormone because I have a deficiency (that's how I got osteoporosis to begin with), and I am also using a low-dose estrogen patch and progesterone.

I will not use drugs like Prolia and Fosamax as I have not found any proof they do any good, and I have found proof that they can cause a great deal of harm. You have to do what you and your doctor think is best for your own body. It might be worth talking to your dentist about Fosamax.

Please do some research into Vitamin K2 - you will likely find some answers there.

I had a very enlightening conversation with my infectious disease doctor about drugs like prolia. She told me she knew about those drugs and she also didn't think I should take them. She said to me exactly what my research into bisphosphonates has already revealed: Those drugs hold onto old bone rather than let it leave the body. That way your bones appear to be getting thicker and thicker - but it is only the old bone that would normally be expelled from the body. So as soon as you stop taking Ptolia, Reclast, etc., you are back to having your bones and nothing more. All the progress you made is only an illusion. She agreed with me that addressing my Human Growth Hormone issue is important, as is taking my vitamins and minerals. I am also on a very low dose of estrogen and progesterone. My DEXA scan score was -5.7. When I was thinking of trying Prolia, the women on the support group on Facebook told me to talk to some women who are in their group (it's a natural remedy for Osteoporosis group). Both of those woman got osteonecrosis from taking Prolia. Both of them no longer had a jaw. One of them was fighting osteonecrosis in a secondary place. They didn't have to say much to convince me. Vitamin K2 (MK4 and MK7) is SO important. I am continuing my research and I will keep everybody posted if I learn anything really great and new. I'm doing vitamin K2 (MK4 and MK7) and vitamin D3, 3 mg of boron 3x daily, food-based calcium 500 mg 2x daily, magnesium 250 mg 2x daily, a good food-based multivitamin, a good food-based vitamin C as well as B complex, CoQ10, PQQ, and NAC (only the CoQ10 is for the bones - but if you take the others with it, you get protection from heart disease), flaxseed oil, turmeric, boswellia, and sunflower lecithin. And I try to down some grass-fed cow collagen daily.

I have osteopenia-osteoporosis. Doctors keep forcing Fosamax on me which I refuse to take , based on my research and previous feedback on side effects and resulting fractures from hundreds of patients (even here at Mayo).
I presently take Citracal (calcium citrate) with vitamin D3 and Vitamin K2. K2 ensures that the calcium is directed towards the bones for absorption, instead of just going into the bloodstream. I take these twice a day and will not get another bone density test for a while because I want to give this approach a chance.
Be careful with the type of calcium you choose. They all serve different purposes and some can be harmful - doing the research is helpful.
I have cervical dystonia where my head has tremors 24/7. Tremors weakened the bones in my neck, which is where bone density tests reveal bone degradation. I’ve dealt with other health issues that probably stripped my body of calcium, but I’ve changed my diet to resolve those issues.
