For bone and dental support, this dairy-free **Calcium Citrate** powder gives you 350mg of elemental calcium per scoop, and the label's two-scoops-a-day routine brings you to 700mg — a solid contribution toward the ~1,000–1,200mg most adults need daily. The citrate form is the real draw here: it absorbs without needing stomach acid, so you can take it on an empty stomach, and it suits older adults or anyone on acid-reducing medications like PPIs.

Aim to get most of your calcium from food first and use this to fill the gap — 700mg from two scoops leaves room for diet to cover the rest without overshooting. That matters because very high supplemental calcium has been linked to cardiovascular concerns, so megadosing isn't the goal. To route this calcium into bone rather than arteries, pair it with vitamin D3 and K2, which this single-ingredient powder doesn't include.
