Dear Migzil – I struggle with constipation because of medication. My doctor told me to take Milk of Magnesia every night. It works wonders with absolutely no side effects. You can get it flavored or plain. The one with the least amount of not so great ingredients is called Good Sense. If you can't find it in the stores, it is sold on Amazon for very little money.
If you take calcium, you should also take Vitamin K2 (mk4, mk7). Vitamin K2 ensures the calcium goes to your bones – not to your kidneys (kidney stones) or arteries. You need to take magnesium and vitamin D3 as well. I can only tolerate 400 mg of magnesium. If you get diarrhea, take less. It will also help with constipation. Magnesium is a natural muscle relaxer. I have posted the website about vitamin K2 written by a nutritionist (doctor) before – and here it is again: https://chrismasterjohnphd.com/blog/2016/12/09/the-ultimate-vitamin-k2-resource
This is a short read that will help you understand about vitamin K2.
There is a great group on Facebook that talks about osteoporosis – and there are nutritionists who write on there all the time giving advice. It is called Osteoporosis Natural Remedies. I have learned so much in that group! Many of the people there only do calcium, magnesium, vitamin D3, K2, and boron – and they are getting their DEXA scan scores reversed from osteoporosis to osteopenia. The problem with the bone-building drugs is that they don't really work. They give the impression of bone growth on the DEXA, but the minute you stop taking those drugs, you pee out all old bone that was hanging around making it look like you had bone griowth. That's what those drugs do – they keep the old, dead bone in your body, and it makes it look like you have new bone growth. But the real problem are the side effects. I talked to a couple of women who got osteonecrosis from those drugs. Not only did their jaws disintegrate, it moved to other areas of their bodies. Once it gets started, it is difficult to stop it. If you go on that Facebook group's timeline and ask about it, you will probably be hooked up with someone who has had it. That's how I found out about it. I went on there the night before I was going to start Prolia and several women started talking to me – two of them called me on the phone and talked to me! My guess is that you already know this. You can also ask your dentist about those drugs. Your dentist will likely have a lot to say.
Whatever you do, I wish you good luck. We are all in this together. I can't wait till this pandemic is over so I can get a DEXA scan. I have no immune system and my doctor won't let me do anything that isn't absolutely necessary. Let us know how it goes.
