Customer Reviews (4.8 / 5 · 5 reviews)

Matthew ★★★★★

My doctor suggested I add calcium with D3 since I'm not big on dairy, and these tablets are surprisingly easy to swallow for being 1000 mg. No chalky aftertaste either, which I was bracing for. Two months in and my levels came back right where they should be.

Robert ★★★★★

I've been taking these calcium tablets for a few months now and my bloodwork finally came back in the normal range, which my doctor was happy about. The 1000 mg plus D3 combo means I don't need a separate vitamin D pill, and the tablets aren't horse-sized like some others I've tried.

Samuel ★★★★★

Two tablets with my breakfast and I don't have to think about my calcium intake all day. The 1,000 mg per serving is exactly what my doctor suggested, and the D3 helps it absorb so I actually feel a difference in my bones.
