Calcium Carbonate, Pure Powder – 340 grams

NOW Calcium Carbonate Pure Powder delivers calcium in one of its most concentrated available forms, with each half-level teaspoon (1.7 g) providing 600 mg of elemental calcium — 75% of the nutrient reference value. The 340 g tub contains a single ingredient: pure calcium carbonate, with no fillers, binders, or preservatives added.

Powder format gives you flexibility that capsules and tablets cannot match. The unflavoured, fine powder blends readily into water, juice, or a smoothie, and the absence of excipients keeps the product as straightforward as possible. NOW has been producing powdered supplements since 1968, and this product reflects their longstanding focus on purity and cost-effective nutrition.

Calcium carbonate is well suited to those who prefer to manage their own serving amounts rather than being fixed to a pre-set tablet dose — including vegans, older adults, and anyone who finds large capsules difficult to swallow. It is an established mineral supplement from a brand with decades of manufacturing experience behind it.
