Clinical Trial Summary

This is a randomized controlled cross-over meal study with the overall aim to investigate the postprandial calcium absorption from calcium permeate compared with calcium carbonate. The hypothesis is that the bioavailability of calcium permeate is equal to or higher than calcium carbonate. This will be investigated in a cross-over design with 10 postmenopausal women age 50-65 as subjects.

At each visit one baseline measurement blood sample will be collected, followed by measurement 60 minutes, 120 minutes, 240 minutes and 360 minutes after ingestion of study products (calcium carbonate, calcium permeat or placebo).	3 months
Secondary	Serum calcium concentration	Blood samples are collected 5 times during subjects three visits. At each visit one baseline measurement blood sample is collected, followed by measurement 60 minutes, 120 minutes, 240 minutes and 360 minutes after ingestion of study products (calcium carbonate, calcium permeat or placebo).	3 months
Secondary	Serum phosphate concentration	Blood samples are collected 5 times during subjects three visits.
