The tablet says 500 mg — does that mean I get 500 mg of calcium? — CALCIUM GLUCONATE TABLETS 500MG N20 - Tathimfarmpreparaty

The 500 mg on the label refers to the weight of calcium gluconate — the calcium salt used in this tablet — not to the amount of pure calcium your body can use. In any calcium salt, the elemental calcium portion is lower than the full tablet weight. This is why the product overview says the benefit depends on the calcium content itself rather than the “500 mg” name alone.

Calcium gluconate is an organic calcium salt that is widely used in tablets and is generally well tolerated. It is one of several common forms of calcium, and each salt contains a different percentage of elemental calcium. So if you compare this product with a calcium carbonate or calcium citrate product, look for the stated elemental calcium amount on the label rather than just the tablet weight.

To figure out how this tablet fits into your day, check the label for the elemental calcium amount or ask a pharmacist. And if you already take a multivitamin or another calcium supplement, keep in mind that the total calcium from all sources should stay sensible.
