Studies showing the effect of prebiotics on mineral absorption.
| Prebiotic | Dose | Subjects | Main Results | Reference |
|---|---|---|---|---|
| Inulin or oligofructose | 17 g of inulin or oligofructose and 7 g for three experimental periods of three days each. | Patients with conventional ileostomy because of ulcerative colitis | No significant effect on calcium, magnesium, zinc, and iron absorption. | [198] |
| FOS or GOS | 15 g/day for 3 weeks | Healthy, nonanemic, male | No significant effect on calcium and iron absorption. | [199] |
| Short chain FOS | 10 g/day for 5 weeks | Healthy, postmenopausal women | No significant effect on calcium absorption. | [200] |
| FOS enriched milk | 5 g FOS/L with light breakfast | Healthy adults | No significant effect on calcium absorption. | [201] |
| Lactulose | 5 or 10 g per day for two 9 days with 19-day washout in between | Post-menopausal women | Calcium absorption increased in a dose-response way. | [202] |
| Trans-galacto-oligosaccharides | 20 g for two 9 days with 19-day washout in between | Post-menopausal women | Calcium absorption increased. | [203] |
| A mixed short and long degree of polymerized inulin-type fructan product | 8 g/day for 8 weeks or 1 year | Calcium absorption increased significantly. | [204] | |
| The mixture of inulin + oligofructose | 8 g/day for two 3 weeks, separated by a 2-week washout period | Girls at or near menarche. | Calcium absorption increased. | [205] |
