Calcium supplementation alone has a small positive effect on bone density. The data show a trend toward reduction in vertebral fractures, but it is unclear if calcium reduces the incidence of non vertebral fractures. Background: Although calcium is one the simplest and least expensive strategies for preventing osteoporotic fractures calcium supplementation is nevertheless not without
These Calcium Carbonates are often used in paints, coatings, thermoplastic and building products. These are manufactured in New England from a high-quality deposit which provides consistency in chemical and mineralogical composition.
In the present study, pigs randomized to the high‐calcium diets had fasted serum total calcium after 6 months similar to that of pigs on the control calcium diet. Serum calcium AUC 0–720 and C max appeared slightly elevated in the dairy and CaCO3 groups after feeding; however, this difference was not significant, likely due to the large variability in response observed between individual pigs.
