A tastier calcium chew might boost bone Health—But does it work?
NCT ID NCT07763509
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial tests whether a calcium-rich food chew, made from milk-derived minerals, is easier for women to take daily than a standard calcium carbonate pill. Women aged 40 to 90 at increased risk for osteoporosis will be randomly assigned to one of the two forms for four weeks. The study tracks how consistently they take it, any stomach issues, and overall satisfaction—without any blood draws or scans. The goal is to see if the form of calcium affects adherence and comfort, which could influence long-term bone health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A calcium-rich food chew providing 500 mg of calcium from milk-derived minerals, compared to a standard calcium carbonate supplement.
- What this could lead to
- If the chew is easier to stick with and gentler on the stomach, it could offer a more acceptable daily calcium option for women trying to protect their bones.
- What could go wrong
- This is a short, four-week study, so long-term bone benefits are not measured. Results may not apply to all women, and the chew could still cause digestive discomfort in some.
