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.
