Amorphous Calcium Carbonate Absorption is 2-Folds Higher |
||||||||||||
Principal investigator: Prof. Nachum -Vaisman, Director of the Clinical Nutrition Unit, Sourasky Medical Center, Tel-Aviv. Study objective: To study the rate of gastrointestinal absorption of amorphous calcium carbonate versus crystalline calcium carbonate in post-menopausal women Study description: · A randomized, double-blind crossover study. · The study included 13 post-menopausal women, with no history of severe illness or vitamin D deficiency. · The study compared calcium absorption using the precise and accurate dual-stable isotope technique, of the most advanced technology, which compared the true fractional calcium absorption from each calcium source. Study results: 1. Absorption of amorphous calcium carbonate in the intestine is 2-folds higher than that of crystalline calcium carbonate — when the calcium is taken after a meal. 2. A single case showed that when taken on an empty stomach, amorphous calcium carbonate absorption in the intestine was 4.6-folds higher than crystalline calcium carbonate. 3. Post-menopausal women whose calcium absorption was significantly low when taking crystalline calcium carbonate (for example, those with a lower BMI) showed better calcium absorption after consuming amorphous calcium carbonate. This study was submitted for publication in a scientific peer-reviewed journal. A full abstract and a link to the published article will be posted after publication |
