I think the reason I got osteoporosis is I didn’t find AlgaeCal til after DX - when I told self I better find some kind of calcium I could tolerate after testing about 15 a decade earlier, starting with those caramels, and finding every one upset my stomach. ( A polite way of saying I pretty much didn’t go to bathroom after a day or two.);2 things I’ve learned just recently: the magnesium that can counteract the calcium’s affect on stomach is magnesium oxide, not glycinate which I had been taking. Also an Algaecal person told me some people can’t digest the magnesium so it can’t help, they lack some kind of vitam8n B 12 and if you take that, the magnesium can do its job. You get something called P5P. I have to look for this.
