This product is a calcium citrate powder, unflavored, sold in an 8 ounce container at around $12.24. The label marks it kosher and vegan, and the maker markets it for bone strength, with calcium citrate noted on the label as a highly bioavailable form.

It has built a solid following, with a 4.6 star average across roughly 1,500 reviews and about 2,000 units bought in the past month. That purchase volume relative to its review count suggests it has picked up steady recent demand.
