Dual x-ray absorptiometry testing of bone mineral density can be used to assess cumulative calcium status over the lifetime because the skeleton stores almost all calcium in the body [3]. Concomitant use of calcium supplements and dolutegravir can reduce blood levels of dolutegravir substantially, apparently through chelation [99,100]. Clinical trials and meta-analyses of RCTs assessing the impact of calcium supplements or increased intakes of calcium from dairy products on prevention of weight gain or promotion of fat loss or weight loss have had mixed results [88-92].

Hypocalcemia (serum calcium level less than 8.5 mg/dL [2.12 mmol/L] or an ionized calcium level below 4.61 mg/dL [1.15 mmol/L]) is usually a result of a vitamin D or magnesium deficiency, impaired parathyroid hormone (PTH) production leading to hypoparathyroidism, impaired bone resorption of calcium, critical illness, or use of certain medications (e.g., bisphosphonates, cisplatin, or proton pump inhibitors) [22,23].
