Osteopenia and Cramping

Thanks so much for the encouragement and helping to keep me on the right track. Yes I am making Colloidal Silver every full moon. I had a cup of vegetable broth yesterday and nothing else. Today I've only had water. Now my toes are cramping. I usually take some horsetail silica to make the cramps go away. The doctor says I have osteopenia. I've heard cramps are caused by calcium leaching. Horsetail silica stops the cramping. I am hesitant to take it without some food in my stomach. But I don't want to mess up the fast because I felt sooo much better when I got done last time. Any thoughts you may have about Osteopenia would be greatly appreciated. Forgive me If I am dominating too much of your time. I know other people need help. TIA G
