Accepts healthy volunteers


The primary objective of this study is to investigate the effects of 12-months supplementation with calcium-enriched permeate, taken alone or in conjunction with inulin, on changes in markers of bone formation and resorption and in bone mass density (BMD) in apparently healthy postmenopausal women compared with calcium-carbonate or maltodextrin supplementation.


The study will include an information visit, a randomization visit, a month 3 visit and a final visit at month 12. Besides, two visits at month 6 and 9 for dispensing of trial products. Outcome parameters will be measured using blood samples obtained at the randomization visit, the month 3 visit and at the final visit at month 12. Outcome parameters will moreover be analyzed based on DXA scan obtained at the randomization visit and at the final visit at 12 months.
