Calcium and magnesium compete for the same absorption pathways and work against each other physiologically — calcium contracts muscle, magnesium relaxes it — so taking calcium alone at high doses without magnesium tends to be counterproductive. Two parts calcium to one part magnesium is the ratio most commonly used to keep the two in balance.\u003c\/p\u003e\n\u003cp\u003eForm matters as much as ratio. Prairie Naturals uses calcium as an amino acid chelate and citrate rather than the cheap carbonate that fills most bone formulas. Carbonate needs stomach acid to dissolve, which is a genuine problem for the older adults who most need calcium and who most often have reduced acid production. Citrate and chelate absorb without that dependency, and the formula includes betaine hydrochloride to support digestion further.\u003c\/p\u003e\n\u003cp\u003eVitamin D3 and zinc round it out — D3 because calcium absorption depends on it, zinc because it participates in bone matrix formation. Horsetail contributes silica, traditionally used for connective tissue. Two sizes: 90 and 180 tablets. Prairie Naturals has been formulating in British Columbia since 1993, without artificial colours, artificial sweeteners or unnecessary fillers.\u003c\/p\u003e\n\u003ch3\u003eWho Prairie Naturals Cal-Mag Force 2:1 Is For\u003c\/h3\u003e\n\u003cp\u003eThis suits anyone building or protecting bone density — post-menopausal women, older adults, people with low dietary dairy, and anyone advised to supplement calcium. Because magnesium is included at a meaningful level it also suits people who take calcium and find they get cramps or constipation from it.\u003c\/p\u003e\n\u003cp\u003eIf you only want magnesium, buy magnesium — this is a calcium-led formula and 400 mg per tablet is a substantial dose. Anyone with heart or kidney problems or cardiovascular disease should consult a practitioner before starting calcium supplementation, as should anyone taking medication that interacts with minerals.\u003c\/p\u003e\n\u003ch2\u003ePrairie Naturals Cal-Mag Force 2:1 Features and Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimal 2:1 Calcium to Magnesium Ratio\u003c\/strong\u003e — 400 mg calcium to 200 mg magnesium, the ratio that keeps the two minerals in balance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmino Acid Chelate and Citrate Forms\u003c\/strong\u003e — Absorbed without depending on stomach acid, unlike the carbonate most bone formulas use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVitamin D3 Included\u003c\/strong\u003e — Calcium absorption depends on adequate vitamin D, so the two belong in the same tablet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZinc for Bone Matrix\u003c\/strong\u003e — 6 mg of zinc citrate, participating in bone tissue formation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBetaine Hydrochloride\u003c\/strong\u003e — Supports the digestion and absorption of the minerals in the formula.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsetail for Silica\u003c\/strong\u003e — Equisetum arvense contributes silica, traditionally used for connective tissue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo Sizes\u003c\/strong\u003e — 90 and 180 tablets, so 45 or 90 days at two tablets daily.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"faq-section\" id=\"faq-prairie-naturals-cal-mag-force-2-1\"\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eProduct Information\u003c\/h3\u003e\n\u003cdetails\u003e\u003csummary\u003e➕ What is Prairie Naturals Cal-Mag Force 2:1?\u003c\/summary\u003e\u003cdiv style=\"padding-left:25px; margin-top:5px; padding-bottom:10px;\"\u003eA bone health formula providing 400 mg calcium and 200 mg magnesium per tablet in chelate and citrate forms, with vitamin D3, zinc, betaine HCl and horsetail.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003e➕ How much do I take?\u003c\/summary\u003e\u003cdiv style=\"padding-left:25px; margin-top:5px; padding-bottom:10px;\"\u003eOne tablet two times daily, or as directed by a health professional.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003e➕ Which size should I buy?\u003c\/summary\u003e\u003cdiv style=\"padding-left:25px; margin-top:5px; padding-bottom:10px;\"\u003eAt two tablets daily, 90 tablets is 45 days and 180 tablets is 90 days.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003e➕ Why does the ratio matter?\u003c\/summary\u003e\u003cdiv style=\"padding-left:25px; margin-top:5px; padding-bottom:10px;\"\u003eCalcium and magnesium compete for absorption and have opposing effects on muscle.
