Calcium Bioavailability from Mineral Waters with Different Mineralization in Comparison to Milk and a Supplement.

What Was Tested

This randomized controlled trial looks at Copper (Supplement).

The aim of the present study was to compare the bioavailability of calcium from 3 mineral waters with different concentrations of minerals with that of milk and a calcium supplement.

Who Took Part

The study group was 21 men.

PubMed indexes the participants as young adults and adults, both men and women.

A single-center, randomized controlled trial with a crossover design with 21 healthy men and women was conducted at the Institute of Food Science and Human Nutrition, Leibniz University Hannover.

How the Study Was Run

In design terms this was a randomized and crossover study.

Random assignment meant chance, not the researchers, decided who got Copper (Supplement) and who got the comparison, which limits bias.

Each person switched between Copper (Supplement) and the comparison at some point, usually with a gap in between.

What Was Measured

PubMed files the paper under topics including Biological Availability, Calcium, Dietary Supplements, Milk and Mineral Waters.

The authors tagged it with the keywords bioavailability, general nutrition and mineralization.

What This Means in Plain Language

The paper is a randomized and crossover study of Copper (Supplement) in 21 men.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.
