Calcium and muscle function -

Five years ago, patients with a very rare disease linked to mutations in the mitochondrial gene MICU1 were described to suffer from a neuromuscular disease with signs of muscle weakness and damage that could not be fully explained. To determine what was going awry, the multi-institutional research team used a comprehensive approach that included fibroblasts donated by a patient lacking MICU1 and an experimental model whose MICU1 gene was deleted in the muscles.

Loss of MICU1 in skeletal muscle fibers leads to less contractile force, increased fatigue and diminished capacity to repair damage to their cell membrane, called the sarcolemma.

Just like human patients, the experimental model suffers more pronounced muscle weakness, increased numbers of dead myofibers, with greater loss of muscle mass in certain muscles, like the quadriceps and triceps, the research team writes.

The missing protein is just supposed to cause atrophy and weakness. Patients with this rare disease show early muscle weakness, fluctuating levels of fatigue and lethargy, muscle aches after exercise, and elevated creatine kinase in their bloodstream, an indication of cell damage due to physical stress.

Bones will release calcium into the blood if the diet does not provide enough, and no symptoms usually occur. A more serious deficiency of calcium, called hypocalcemia, results from diseases such as kidney failure, surgeries of the digestive tract like gastric bypass, or medications like diuretics that interfere with absorption.

A gradual, progressive calcium deficiency can occur in people who do not get enough dietary calcium in the long-term or who lose the ability to absorb calcium.

The first early stage of bone loss is called osteopenia and, if untreated, osteoporosis follows. Examples of people at risk include:. After a diagnosis of osteoporosis, your physician may prescribe over-the-counter calcium supplements. However, there are several points to consider when using calcium supplements.

Too much calcium in the blood is called hypercalcemia. The Upper Limit UL for calcium is 2, mg daily from food and supplements. People over the age of 50 should not take more than 2, mg daily, especially from supplements, as this can increase risk of some conditions like kidney stones, prostate cancer, and constipation.

Some research has shown that in certain people, calcium can accumulate in blood vessels with long-term high doses and cause heart problems. Calcium is also a large mineral that can block the absorption of other minerals like iron and zinc.

Certain nutrients and medications may increase your need for calcium because they either lower the absorption of calcium in the gut or cause more calcium to be excreted in the urine. These include: corticosteroids example: prednisone , excess sodium in the diet, phosphoric acid such as found in dark cola sodas, excess alcohol, and oxalates see Are anti-nutrients harmful?

Blood pressure Several literature reviews on the topic of total calcium intake, from food and supplements, and blood pressure have suggested a possible link to lowering high blood pressure.

Cardiovascular disease Some research has raised concerns about calcium supplements and heart health. Bone health Calcium is one of the most important nutrients required for bone health.

Possible reasons: The study only looked at calcium intakes from a supplement provided to the participants, and did not account for calcium from the diet or estimate the total amount of calcium from both food and supplements. The trial did not find a difference in incidence of colorectal cancer between the two groups.

Kidney stones At one time, experts recommended that people with kidney stones limit their calcium intake because the mineral makes up one of the most common types of stones, called calcium-oxalate stones.

The amount of calcium listed on the Nutrition Facts label of a food product is the measure of calcium in the food, but not necessarily the amount the body will absorb.

Guidelines if you are taking calcium supplements for osteoporosis After a diagnosis of osteoporosis, your physician may prescribe over-the-counter calcium supplements.

First, clarify with your physician how much total calcium you should take daily. This amount includes calcium from food and supplements. The RDA for adults is between 1,, mg daily, depending on age.

Taking more than 2, mg daily is not recommended for adults even with osteoporosis, as this can potentially lead to other health problems.

It is not recommended to take more than 1, mg daily, even with a diagnosis of osteoporosis. Taking too high an amount of calcium at one time, particularly from a supplement, can actually lower the absorption of the mineral. It is best to take no more than mg at one time. If you are prescribed more than that, take each dose at least 4 hours apart.

So if you are prescribed mg of calcium daily, you might take a mg supplement with breakfast and then again at night with dinner. The two most common types of calcium supplements are in the form of calcium carbonate and calcium citrate. The carbonate form needs to be broken down by stomach acid before it can be absorbed, so it is usually taken with food; the citrate form does not require stomach acid and can be taken without food.

If you are unsure about how much calcium you are getting from the diet, consult with a registered dietitian. You would subtract the estimated amount of calcium from food from the RDA or prescribed amount by your doctor; the remaining can be taken as a supplement. If you are eating a very high calcium diet f e.

Muscle Brown rice protein is a crucial physiological Regulate sugar cravings that enables the body to carry Anv a variety of motions, keep its posture, and avoid injury. Moreover, Calcium and muscle function is one of the amd Regulate sugar cravings required for muscle cunction because it helps the muscles use the nutrients they already have. Calcium plays a critical role in muscle contraction and relaxation; low levels of this mineral can result in muscle cramps, spasms, and even muscle weakness. The relationship between calcium and muscle relaxation, as well as the advantages of calcium supplement s for encouraging normal muscle function, will be discussed in this blog post today. Understanding how muscles contract and relax is necessary before discussing calcium's role in muscle relaxation.
