Many have heard the expression - deficiency of magnesium or potassium in the body, but not everyone knows what the condition is and what it is fraught with. Today we will talk about how important these macronutrients are for the normal functioning of our body. How to fill their shortage? Will magnesium and potassium tablets help?
What are magnesium and potassium for our body?
The mentioned elements of the periodic chemical table are important enough minerals to perform certain functions by our body. Mg (magnesium) is one of the most important minerals that is involved in more than 300 enzymatic reactions, especially in the production of energy. Our body contains about 30 grams of this element.
Magnesium plays the role of a catalyst and is located in the center of the main biochemical reactions:
- Provides muscle contraction by transmitting signals from nerve endings.
- Participates in the metabolism and energy production, as well as in the processes of splitting carbohydrates, glycolysis and lipolysis, the conversion of fats.
- Magnesium solubility-N-balance, due to which potassium and calcium are retained in the body. Therefore, it is important to use these salts to form bone growth and growth.
- It participates in immune mechanisms, acts as a cardioprotector and ensures vascular health.
The chemical element, which is denoted by the symbol K (potassium), is equally important for our health. Consider its main functions in the body:
- it works in close contact with sodium to maintain the acid-base balance of the body and fluid;
- is of great importance for the transmission of nerve impulses;
- indispensable to ensure muscle contraction, including cardiac;
- participates in the functioning of the kidneys and adrenal glands;
- promotes protein synthesis and carbohydrate metabolism.
When is prescribed magnesium and potassium drugs?
These elements are not produced in the body, so they must be consumed with food, and in the event of a deficiency - in the process of therapy with drugs. The recommended daily intake of magnesium is 6 mg / kg body weight per day in adults with moderate activity: about 360 mg for women and 420 mg for men.
The recommended average potassium intake should be 4,700 mg per day. In fact, it is estimated only 2300 mg in women and 3100 mg in men, that is, there is a chronic lack of potassium.
Magnesium deficiency can occur in such cases:
- with improper diet;
- as a result of stress and nervous strain;
- due to severe physical exertion;
- with excessive use of caffeine-containing beverages and alcohol.
Signs of magnesium deficiency:
- anxiety and irritability;
- difficulty concentrating;
- muscle weakness;
Preparations of potassium and magnesium tablets are also prescribed for cardiovascular prophylaxis.
Potassium deficiency is manifested by the following symptoms:
- fatigue and weakness;
- muscle spasms;
- intestinal lethargy;
- bloating and abdominal pain;
If insufficient intake of potassium is systematic, it can cause its real deficiency - hypokalemia. And severe hypokalemia can lead to muscle paralysis and cardiac arrhythmias. As a rule, adequate dietary intake of potassium is enough to cover the deficit, but severe cases require medication.
Potassium preparations are prescribed when there is a threat of the development of such illnesses:-
- heart disease;
- reduce bone density and osteoporosis;
- dental problems.
Contraindications and side effects
There are a number of contraindications and side effects associated with these funds. In addition, there may be a negative interaction with other drugs, as many drugs can cause an excess or deficiency of these important elements for the body.
This element is eliminated by the kidneys, and when they do not work very well, it can accumulate in the body and cause poisoning. People suffering from diseases of the upper GI tract and esophagus, stomach and duodenum, should take potassium exclusively in liquid form. Pregnant and lactating mothers should refrain from taking such drugs.
Possible side effects:
- constipation, and sometimes diarrhea;
- pain or discomfort in the abdomen, vomiting possible;
- may trigger internal bleeding.
Such drugs are not recommended for patients with renal insufficiency.
They are also contraindicated in the joint administration of diuretics, antibiotics, certain heart drugs, anticancer drugs and against osteoporosis.
What is dangerous surplus of these macronutrients?
This is the case when a lot does not mean good. For example, excessive accumulation of potassium in the body causes the following conditions:
- irregular heartbeat;
- tiredness or unusual weakness;
- numbness of fingers or toes;
- labored breathing.
Excess magnesium may cause these symptoms:
- diarrhea with intestinal disorders due to its laxative properties;
- nausea and vomiting;
- lower blood pressure;
- dry mouth;
- muscle weakness;
- in extreme cases, coma or cardiac arrest.
It should be borne in mind that our kidneys are capable of removing up to 6 g of magnesium per day, so its excess can be especially dangerous for people with renal insufficiency.
Potassium and Magnesium Tablets: Overview
On the basis of these macronutrients there are a variety of drugs, presented in the form of medicines, nutritional supplements or vitamins potassium + magnesium + calcium tablets:
- "Panangin". It is also called vitamins for the heart. It is taken for serious violations of the heart rhythm, mainly caused by hypokalemia.
- Asparks. The drug has a regulating effect on the processes of cellular metabolism, restores electrolytic balance, has anti-arrhythmic effect.
Nutritional supplements and, moreover, potassium and magnesium tablets should be taken only under medical supervision. Take care of yourself!
