Calcium lactate

Calcium lactate is a mineral that treats or prevents low blood calcium levels (hypocalcemia) in people who do not get enough calcium from their diet.

Calcium lactate is also used to treat conditions like osteoporosis, issues with the parathyroid gland, or some muscle problems.

Calcium lactate works best if you take it with food.

Drink plenty of liquids every day.
