Emma M. ★★★★★ Oct 14, 2026

My doctor suggested a citrate form since it's gentler on the stomach, and this one has the D3 already mixed in so I don't need a second pill. Two tablets with breakfast and I've had zero stomach upset, which was my main worry with calcium.

Ellie S. ★★★★★ Oct 13, 2026

Been taking these for about six months now, and my last bone density scan actually showed improvement, which my doctor was pleased about. The D3 added in makes a difference since I don't get much sun. Tablets are a bit large but I swallow them fine with breakfast.

Switched to citrate after struggling with the carbonate pills for months, and these go down so much easier on my stomach. The added D3 is a nice bonus since I don't get much sun in winter. Two tablets a day and I'm set.
