Calcium – What Is It?
Calcium (Malate) is one of many ingredients in the Tikva product. It is the most abundant mineral in the human body, has several important functions. More than 99% of total body calcium is stored in the bones and teeth where it functions to support their structure. The remaining 1% is found throughout the body in blood, muscle, and the fluid between cells. It is needed for muscle contraction, blood vessel contraction and expansion, the secretion of hormones and enzymes, and sending messages through the nervous system. A constant level of calcium is maintained in body fluid and tissues so that these vital body processes function efficiently.

Calcium is a mineral that the body needs for numerous functions, including building and maintaining bones and teeth, blood clotting, the transmission of nerve impulses, and the regulation of the heart’s rhythm. Ninety-nine percent of the calcium in the human body is stored in the bones and teeth. The remaining 1 percent is found in the blood and other tissues.
The body gets the calcium it needs in two ways. One is by eating foods or supplements that contain calcium. Good sources include dairy products, which have the highest concentration per serving of highly absorbable calcium, and dark leafy greens or dried beans, which have varying amounts of absorbable calcium. Calcium supplements often contain vitamin D; taking calcium paired with vitamin D seems to be more beneficial for bone health than taking calcium alone.
The other way the body gets calcium is by pulling it from bones. This happens when blood levels of calcium drop too low, usually when it’s been awhile since having eaten a meal containing calcium. Ideally, the calcium that is “borrowed” from the bones will be replaced at a later point. But, this doesn’t always happen. Most important, this payback can’t be accomplished simply by eating more calcium.
Calcium Health Benefits
Heart Disease – Blood Pressure
Some studies have found that supplementation can keep blood pressure in check. A few studies even indicate that a diet rich in this mineral, derived from low-fat dairy products, fruits, and vegetables may be as effective as some prescription medications at lowering high blood pressure. Because it helps muscles to contract, it also keeps the heart and blood vessels performing efficiently.
Maintain healthy bones and prevent or slow osteoporosis.
Getting enough of this mineral every day, over a lifetime, will help prevent osteoporosis (bone-thinning disease), which can gradually lead to bone fractures, stooped posture, and loss of height. Although the body is best equipped to absorb it and establish adequate bone mass (mineral content) before age 35, everyone can benefit from high calcium intake to maintain the health of bones (and teeth). In fact, studies of people over age 65 show that adding calcium-rich foods and supplements to their diet reduces their risk of bone loss and fractures. A three-year study of 176 men and 213 women over age 65 taking either 500 mg of calcium plus 700 IU of vitamin D3 daily found the supplementation moderately reduced bone loss in the femoral neck, spine and total body and reduced the incidence of nonvertebral fractures.
Ease the symptoms of PMS
A growing body of research indicates that supplementation may relieve irritability, mood swings, depression, and other PMS symptoms. The theory is that low levels contribute to PMS-related hormonal imbalances.
In a randomized, double-blind, placebo-controlled clinical trial of 466 women, supplementation (1,200 mg/day) for three menstrual cycles was associated with a 48% reduction in total symptom scores, compared to a 30% reduction observed in the placebo group.

Fight insomnia and Prevent migraines
Some people experience sleep problems when they become deficient in calcium. Supplementing with calcium and magnesium–another nutrient that may be depleted in insomnia sufferers–may ultimately lead to sounder slumber.
Taking these together on a long-term basis may thwart debilitating headaches. Both minerals help to maintain healthy blood vessel function throughout the body, including the brain.
