Calcium Fact Sheet: The National Institutes of Health Office of Dietary Supplements
Calcium is needed for muscle contraction, blood vessel contraction and expansion, the secretion of hormones and enzymes, and sending messages through the nervous system. Vitamin D helps improve calcium absorption.
Calcium-Magnesium Cellular Nutrition
Calcium and Magnesium intracellular attributes, interactions, deficiency/toxicity risk factors, and sources.
Calcium is the most abundant mineral in the body and is essential for the development and maintenance of strong bones and teeth. Excessive intake of protein, sodium, phosphates (from carbonated beverages), alcohol or caffeine can lead to diminished calcium levels in the body.
Magnesium: A Key to Calcium Absorption
Magnesium is needed for calcium absorption. Calcium causes muscles to contract, while magnesium helps them relax.
Calcium and Phosphorus for Bone Health
Calcium and Phosphorus work closely together to build strong bones and teeth. The delicate balance between calcium and phosphorous is necessary for proper bone density and prevention of osteoporosis. When there is more phosphorus than calcium in the system, the body will draw on calcium stored in bones. This can lead to reduced bone mass (namely, osteopenia or osteoporosis) that makes bones brittle and fragile. It can also lead to gum and teeth problems.
Studies of the Interaction Between Boron and Calcium
Two experiments were performed to confirm that boron interacts with calcium, and that this interaction can be modified by dietary magnesium and potassium in the rat.
Endocrine Control of Calcium and Phosphate Homeostasis
It would be very difficult to name a physiologic process that does not depend, in one way or another, on calcium. here are three major pools of calcium in the body: intracellular calcium, calcium in blood and extracellular fluid, and bone calcium.
