Clinical Trial Summary

This research was designed in accordance to the Method for Efficacy Assessment of Health Food for Bone Heath. Changes to bone density were measured to evaluate the effectiveness of amorphous calcium carbonate in maintaining bone health.

Description:

Bone comprises organic matter, predominantly protein, and inorganic matter including various mineral salts. Inappropriate nutrition profile can affect the balance of bone metabolism and cause bone loss. Of all nutrients, calcium is considered the most important for bone structure and metabolism. It is the most common deficit that affects bone health. Low dietary calcium intake can lead to negative calcium balance. Low blood calcium (< 10mg/dL) induces the release of parathyroid hormone (PTH), which activates the conversion process of 25-(OH)-D3 to physiologically active 1,25-(OH)2-D3 in kidneys. PTH and 1,25-(OH)2-D3 act jointly to change the ionic valence of hydroxyapatite, converting orthophosphate to pyrophosphate. This causes hydroxyapatite to easily dissociate and release calcium ion in order to compensate the blood calcium level. This is called bone resorption. While this physiological mechanism maintains blood calcium homeostasis, it also causes bone loss that can develop into osteoporosis. Negative calcium balance is not only caused by lack of dietary calcium, hormonal abnormality or vitamin D deficit may also lead to negative calcium balance and the development of osteoporosis. This study aims to assess the effects of UIC Amorphous Calcium on osteoporosis with "Bone Change Test" and "Calcium Bioavailability Test".
