NOW Calcium Carbonate Powder

Calcium as carbonate powder — commonly ~600 mg elemental per 1/2 level teaspoon. Shortlisted as the measured-powder lane. Mix with a mealtime drink; this is not a Flavour spice jar.

Form
Pure calcium carbonate powder; listing often ~600 mg elemental per 1/2 tsp (1.7 g) — confirm label

Empty-stomach use; heaping scoops; stacking with Caltrate or citrate without counting; a Flavour-aisle jar

Why it is on the shortlist

Powder makes the salt obvious — no hidden bone-multi blend. Map: Calcium. Grocery tablet of the same salt family: Caltrate 600+D3.

Boundaries

Carbonate wants food. Do not treat a heaping spoon as a free extra. Kidney-stone and excess-calcium questions belong with a clinician. Food still first: dairy, calcium-set tofu, greens.
