Magnesium, Calcium, Potassium: Benefits

Magnesium, Calcium, Potassium, Sodium, Chloride, Phospate are all electrolytes. Electrolytes are minerals in body fluids, so if you are dehydrated, your body does not have enough fluid and electrolytes. Since each of them plays a role in hundreds of body functions, having too much or too little may give you health problems.

 

In this article, we will explain magnesium, calcium, potassium benefits for some health issues. But first, we need to know each of these minerals for better understanding.

 

Magnesium involved in muscle and neuron function, blood pressure and blood sugar regulation, and even bone and DNA formation. Magnesium may also help you sleep better and aid in the relief of anxiety and depression. Moreover, Magnesium also plays a role in the active transport of calcium and potassium ions across cell membranes, a process that is important to nerve impulse conduction, muscle contraction, and normal heart rhythm

 

Potassium plays a vital role in managing fluids, nerve signals, and muscle contractions. It also helps your body regulate your blood pressure, heart rhythm and the water content in cells.  

 

Calcium is a mineral most often associated with healthy bones and teeth. Almost all calcium is stored in bones and teeth to help make and keep them strong. Moreover, calcium helps muscles and blood vessels contract and expand, and to send messages through the nervous system. Calcium is also used to help release hormones and enzymes that affect almost every function in the human body.

Magnesium, Calcium, Potassium: Benefits

A. Magnesium, Calcium, Potassium for Blood Pressure

Abstract Dietary intakes of potassium, calcium, and magnesium have each been reported to lower blood pressure, but the extent of blood pressure reduction in epidemiological studies and clinical trials has tended to be small and inconsistent. 

i. Magnesium and Blood Pressure

Magnesium may lower blood pressure by acting like a natural calcium channel blocker. Specifically, magnesium competes with sodium for binding sites on vascular smooth muscle cells, increases prostaglandin E, binds to potassium in a cooperative manner, and induces endothelial-dependent vasodilation and BP reduction. (Source)

 

Magnesium intake of 500 mg/d to 1000 mg/d may reduce blood pressure (BP) as much as 5.6/2.8 mm Hg. However, clinical studies have a wide range of BP reduction, with some showing no change in BP. 

 

Magnesium also increases the effectiveness of all antihypertensive drug classes.  

 

The combination of increased intake of magnesium and potassium coupled with reduced sodium intake is more effective in reducing BP than single mineral intake and is often as effective as one antihypertensive drug in treating hypertension. Reducing intracellular sodium and calcium while increasing intracellular magnesium and potassium improves BP response. (Source

ii. Potassium and Blood Pressure

Foods that are rich in potassium are important in managing high blood pressure (HBP or hypertension) because potassium lessens the effects of sodium. The more potassium you eat, the more sodium you lose through urine. Potassium also helps to ease tension in your blood vessel walls, which helps further lower blood pressure.

 

Increasing potassium through diet is recommended in adults with blood pressure above 120/80 who are otherwise healthy. Potassium can be harmful in patients with kidney disease, any condition that affects how the body handles potassium, or those who take certain medications. The decision of whether to take excess potassium should be discussed with your doctor. (Source)

iii. Calcium and Blood Pressure

A study showed that, particularly in individuals with low calcium intake, an increase in calcium intake reduces blood pressure.

 

Three major mechanisms explaining the relationship between a low calcium intake and the increase in blood pressure: (a) parathyroid function, (b) vitamin D, and (c) the renin–angiotensin–aldosterone system (RAAS).

These three mechanisms are described on: (See More).

 

However, in large amounts, calcium supplements may interact with some blood pressure medications. So, if you are consuming blood pressure medication, best consult your doctor before taking calcium supplement.

B. Magnesium, Calcium, Potassium for Bone Health

i. Calcium and Bone Health

Calcium is needed for bone health. Your body cannot make calcium, so you need to get the calcium through your diet or from supplements.

 

Adequate calcium intake throughout lifetime is important for bone health and the prevention of osteoporosis and related fractures. (Source

 

Children need calcium to build strong bones. Adults need calcium to maintain strong bones. Almost all calcium in the body is stored in bones and teeth, giving them structure and hardness.

 

Calcium deficiency won’t produce short-term symptoms because if you don’t get enough calcium in your diet, your body will take it from your bones to ensure normal cell function, which can lead to osteoporosis or weakened bones.

ii. Magnesium and Bone Health

On the basis of experimental and epidemiological studies, both low and high magnesium have harmful effects on the bones. 

Magnesium is a component of bone; in fact 60% of the body’s magnesium is stored in bone. It is also involved with the activity of bone-building cells and the parathyroid hormone, which regulates calcium levels. (Source

 

Mg deficiency in humans contributes to osteoporosis. Low serum Mg is a co-contributing factor to osteopenia in adults with sickle cell anemia [Source]. Moreover, an association between serum Mg and bone density has been reported in pre and post menopausal women. Mg intake was positively associated with bone mass density in surviving members of the Framingham study [Source]

 

Mg deficiency associates with the reduction of the levels of PTH, the induction of end-organ resistance to PTH and the decrease of vitamin D. Interestingly, many osteoporotic post-menopausal women who are vitamin D deficient and have low PTH levels are also Mg deficient and Mg supplementation corrects these biochemical abnormalities. Moreover hypomagnesemic diabetic children normalize their levels of 1,25(OH)2-vitamin D upon supplementation with Mg. (Source

 

In addition, Mg deficiency also associates with low grade inflammation and inflammatory cytokines stimulate bone remodelling and osteopenia.

iii. Potassium and Bone Health

Dietary potassium may neutralize acid load and reduce calcium loss from the bone, leading to beneficial effect on bone mineral density. A study showed that dietary potassium intake was positively associated with BMD in men aged >50 years and postmenopausal women, indicating the beneficial effects of dietary potassium intake on bone health. 

 

Another findings indicate that higher dietary potassium levels have a favorable effect on bone health and preventing osteoporosis in older Korean women. Daily potassium intake was significantly related to a decreased risk of osteoporosis at the lumbar spine in postmenopausal women. 

C. Magnesium, Calcium, Potassium for Sleep

Calcium, magnesium, potassium, and sodium oxybate is used to treat adults who have idiopathic hypersomnia (IH; a sleep disorder that may cause excessive daytime sleepiness and uncontrollable urge to sleep during daily activities despite adequate or prolonged nighttime sleep).

 

Calcium, magnesium, potassium, and sodium oxybate is in a class of medications called central nervous system depressants. Calcium, magnesium, potassium, and sodium oxybate works to treat narcolepsy, cataplexy, and idiopathic hypersomnia by reducing activity in the brain.

 

However, calcium, magnesium, potassium, and sodium oxybate may cause serious side effects. You must consult a doctor first before taking this.

ii. Magnesium and Sleep Quality

Magnesium may improve your sleep quality. Studies show that magnesium helps stimulate your body’s parasympathetic nervous system, which helps you feel calm and relaxed (Source).

 

Magnesium is also involved in the production of GABA in the brain. GABA is what is known as an inhibitory neurotransmitter, which promotes relaxation. If you don’t have enough magnesium to produce adequate amounts of GABA, your sleep will likely suffer. 

 

A study showed that supplementation of magnesium appears to improve subjective measures of insomnia such as ISI score, sleep efficiency, sleep time and sleep onset latency, early morning awakening, and likewise, insomnia objective measures such as concentration of serum renin, melatonin, and serum cortisol, in elderly people. 

iii. Calcium and Sleep Quality

Calcium intake was associated with decreased difficulty falling asleep and non-restorative sleep. Although published evidence linking dietary calcium (or calcium supplementation) with insomnia symptoms, fewer sleep difficulties associated with increased calcium may have been a result on effects of calcium on lowering blood pressure. (Source

 

Another study concluded that disturbances in sleep, especially the absence of REM deep sleep or disturbed REM sleep, are related to a calcium deficiency. Restoration to the normal course of sleep was achieved following the normalization of the blood calcium level.

 

William Sears, M.D. writes: “Calcium helps the brain use the amino acid tryptophan to manufacture the sleep-inducing substance melatonin. This explains why dairy products, which contain both tryptophan and calcium, are one of the top sleep-inducing foods.” (Source)

iv. Potassium and Sleep Quality

Potassium is also an important element to human health and a natural muscle relaxant as well. According to one study, potassium levels also play a role in sleep, with more benefiting slumber time.

 

Another study may indicate an improvement in sleep consolidation with potassium supplementation. Potassium significantly increased actigraphic Sleep Efficiency due to a reduction in actigraphic Wake after Sleep Onset (WASO). However, further studies using standard polysomnography are required to define potassium’s effects on human sleep.

D. Magnesium, Calcium, Potassium for Muscle Cramps

i. Magnesium, Calcium, Potassium and Muscle Cramps

Calcium, magnesium and potassium for leg cramps

A muscle cramp is a sudden and involuntary contraction of one or more of your muscles. Though generally harmless, muscle cramps can make it temporarily impossible to use the affected muscle.

 

Too little potassium, calcium or magnesium in your diet can contribute to leg cramps. Diuretics — medications often prescribed for high blood pressure — also can deplete these minerals.

 

Getting enough these minerals is essential to keeping your muscle healthy. It’s best to get these through your diet, however if still not adequate, supplements may help.

How to Balance Calcium Magnesium and Potassium

A well-balanced diet should give you all the nutrients your body needs to properly function. Here are the best food source lists for potassium, magnesium and calcium.

 

However, lifestyle, disease and aging can prevent you from getting enough essential minerals like potassium, magnesium and calcium. Your doctor may recommend you nutritional supplements for this situations.
