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.

Scientists probe source of pulsing signal in the sleeping brain

New findings clarify where and how the brain's "slow waves" originate. These rhythmic signal pulses, which sweep through the brain during deep sleep at the rate of about one cycle per second, are assumed to play a role in processes such as consolidation of memory.

Maternal vitamin D levels not found to affect children’s bone health

A study of nearly 4000 pairs of mothers and their children in the Children of the 90s study at the University of Bristol has shown that maternal vitamin D levels during pregnancy are not associated with the child’s bone health in later life. The research, published Online First in The Lancet, is the largest ever observational study of the effects of mothers’ vitamin D levels in pregnancy on their children’s bone health, and suggests that UK health guidelines may be overstating the importance of vitamin D supplementation in pregnancy.
