NUTRITION WHY’S #29: WHY CALCIUM? Calcium along with iron are the most commonly reported nutritional deficiencies in women. Calcium is one of the most abundant minerals in the body with 85% deposited in a kilogram (2.2 pounds) of calcium in bone. Daily balance of calcium is extremely important. Calcium triggers muscle contraction by binding to a protein called Troponin which releases the prepared muscle fibers to contract instantly as the calcium flows into vertical channels between the muscle fibers. Calcium is also involved in hormone secretion, and nerve conduction. For all these reasons blood levels of calcium are tightly regulated by vitamin D and parathyroid hormone which is secreted from four tiny glands in the neck behind the thyroid whenever calcium levels fall. Calcium is removed from the bones, gut, and kidney to restore blood levels to normal. Many people don’t get enough calcium in the diet where the major sources are dairy products, grains and vegetables. So supplements with Calcium, magnesium and vitamin D are needed to reach the recommended amounts of 1000 mg per day for men and 1000 milligrams for women until age 50 when postmenopausal women need 1500 mg per day due to a drop in absorption of calcium from the intestines. Calcium that is not absorbed plays an important role in gut health by binding certain fats and acids which helps maintain normal colon cell function. The upper limit for calcium intake is 2500 mg which should not be approached as excessive calcium can lead to kidney stones. Getting the right nutrients of protein, calcium, vitamin D, and magnesium is just the first step in building bone. You also need resistance exercise which deposits calcium along force lines in the bone which generate a tiny electric current. Like muscle protein, bone calcium is lost with sedentary lifestyle. Remember to take your Protein-Rich Shake and Calcium Supplement every day for healthy bones and muscles!!! #drdavidheber #calcium #bones #muscles to learn more go to www.drdavidheber.com and www.herbalifenutritioninstitute.com
