Calcium News and Research

RSS

Calcium, the most abundant mineral in the body, is found in some foods, added to others, available as a dietary supplement, and present in some medicines (such as antacids). Calcium is required for muscle contraction, blood vessel expansion and contraction, secretion of hormones and enzymes, and transmitting impulses throughout the nervous system. The body strives to maintain constant concentrations of calcium in blood, muscle, and intercellular fluids, though less than <1% of total body calcium is needed to support these functions.

The remaining 99% of the body's calcium supply is stored in the bones and teeth where it supports their structure. Bone itself undergoes continuous remodeling, with constant resorption and deposition of calcium into new bone. The balance between bone resorption and deposition changes with age. Bone formation exceeds resorption in growing children, whereas in early and middle adulthood both processes are relatively equal. In aging adults, particularly among postmenopausal women, bone breakdown exceeds formation, resulting in bone loss that increases the risk of osteoporosis over time.

NTRILIPIX (fenofibric acid) in combo with Rosuvastatin calcium shows improvement on key lipids for cholesterol management

Data from a new study showed that Abbott's TRILIPIX (fenofibric acid) delayed-release capsules in combination with rosuvastatin calcium met all of the study's primary endpoints.

CRESTOR found to reduced CV risk in patients achieving low LDL-C and hsCRP targets in new Jupiter analysis

Results from a new sub-analysis of the JUPITER study show that patients who attained a dual treatment target of LDL-C <70mg/dL and high-sensitivity C-reactive protein (hsCRP) <2mg/L with CRESTOR (rosuvastatin) 20mg achieved a greater reduction in cardiovascular events compared to placebo than those who did not (65% vs 36%, p=0.033) among men and women with low to normal cholesterol levels and elevated hsCRP.
