It is a <strong>soft, silvery metal<\/strong> that is highly reactive with both water and air. If you were to drop a piece of pure potassium into water, it would result in an immediate and explosive reaction. Due to this high reactivity, potassium<strong> does not exist in its pure form in nature but only in compounds,<\/strong> such as potassium salts.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>In the human body, potassium primarily exists <strong>in the form of a cation (a positively charged ion),<\/strong> which is present in every tissue. It plays a crucial role in transmitting nerve impulses and, <strong>as an electrolyte, is involved in regulating fluid balance both inside and outside of cells.<\/strong><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Potassium is an <strong>essential nutrient<\/strong> that our body cannot produce on its own. Additionally, we are unable to store reserves for later use. This is why it\u2019s<strong> important to maintain a well-balanced <a href=\"https:\/\/gymbeam.com\/blog\/what-to-eat-and-how-to-exercise-to-finally-gain-muscle\/\">diet<\/a> with plenty of potassium-rich foods<\/strong> and, if necessary, consider dietary supplements to ensure adequate intake. <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[1\u20132]<\/sup><\/mark><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1124\" height=\"739\" src=\"https:\/\/gymbeam.cz\/blog\/wp-content\/uploads\/2024\/09\/iStock-676447482-1124x739.jpg\" alt=\"What is potassium, and what are its effects?\" class=\"wp-image-613716\" title=\"What is potassium, and what are its effects?\" srcset=\"https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/iStock-676447482-1124x739.jpg 1124w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/iStock-676447482-400x263.jpg 400w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/iStock-676447482-1536x1009.jpg 1536w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/iStock-676447482-2048x1346.jpg 2048w\" sizes=\"auto, (max-width: 1124px) 100vw, 1124px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_the_Function_of_Potassium_in_the_Body\"><\/span>What Is the Function of Potassium in the Body?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Approximately 90% of the absorbed potassium is used by the body to maintain its optimal levels, both inside and outside of cells. This balance is particularly important for the proper functioning of<strong> three key bodily processes.<\/strong> <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[1]<\/sup><\/mark><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">1. It supports the normal functioning of the nervous system<\/h3>\n\n\n\n<p>Potassium is key for the <strong>transmission of nerve impulses<\/strong> between cells. It functions as an electrolyte, regulating the electrical charge across cell membranes. It moves between the internal and external environments of the cell, <strong>enabling proper signal transmission.<\/strong> This process is essential for all nervous system functions, from reflexes to conscious movements. <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[3]<\/sup><\/mark><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">2. It helps maintain normal blood pressure<\/h3>\n\n\n\n<p>Both sodium and potassium influence blood pressure regulation. Sodium retains water in the body, ultimately increasing blood pressure. Potassium, on the other hand, helps the body excrete excess sodium, which supports the removal of surplus water, <strong>leading to a reduction in blood pressure.<\/strong> This process is essential for the proper functioning of the heart and blood vessels. <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[5]<\/sup><\/mark><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">3.

During each muscle contraction, there is an exchange of potassium and sodium between the internal and external environments of the muscle cell. This sodium-potassium pump helps maintain the correct charge inside and outside the cell, <strong>allowing it to respond properly to signals from the nervous system.<\/strong> Without this mechanism, our muscles simply wouldn&#8217;t function effectively. <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[4]<\/sup><\/mark><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1124\" height=\"749\" src=\"https:\/\/gymbeam.cz\/blog\/wp-content\/uploads\/2024\/09\/8a90844c-7eb7-4f88-aeef-366c99665d51-1124x749.jpg\" alt=\"Potassium and muscle function\" class=\"wp-image-613735\" title=\"Potassium and muscle function\" srcset=\"https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/8a90844c-7eb7-4f88-aeef-366c99665d51-1124x749.jpg 1124w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/8a90844c-7eb7-4f88-aeef-366c99665d51-400x267.jpg 400w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/8a90844c-7eb7-4f88-aeef-366c99665d51-1536x1024.jpg 1536w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/8a90844c-7eb7-4f88-aeef-366c99665d51.jpg 2000w\" sizes=\"auto, (max-width: 1124px) 100vw, 1124px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Are_the_Effects_of_Potassium_on_Health_and_Sports_Performance\"><\/span>What Are the Effects of Potassium on Health and Sports Performance?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Adequate potassium intake is crucial for maintaining overall health and sports performance. Due to modern dietary habits, which often lack fresh foods and are high in ultra-processed items, <strong>there is a risk of potassium deficiency.<\/strong> This deficiency can negatively impact both health and physical performance. Health authorities, such as the WHO and the European Society of Cardiology, frequently highlight the importance of sufficient potassium intake. This is why the DASH diet exists, which is rich in fresh vegetables, fruits, legumes, whole grains, and other potassium-rich foods. It is recommended for the prevention of high blood pressure and other cardiovascular diseases. <sup>[6\u20137]<\/sup><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">What areas of our everyday lives does it impact the most?<\/h3>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"heart\">1. Supports heart function<\/h3>\n\n\n\n<p>Potassium influences heart function on multiple levels. Firstly, as one of the main electrolytes, it plays a crucial role in transmitting electrical signals between heart cells. This is essential for maintaining<strong> a regular heart rhythm,<\/strong> allowing the heart muscle to contract and relax effectively. As a result, <strong>blood is pumped efficiently throughout the body.<\/strong> <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[6]<\/sup><\/mark><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>This mineral also impacts heart function through its effect on blood pressure. As mentioned earlier, it helps <strong>excrete excess sodium, thereby regulating the volume of circulating blood.<\/strong> This action reduces the risk of developing high blood pressure (hypertension), which places a significant strain on the heart.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>The positive effect of potassium on heart function and blood pressure is supported by numerous studies. For example, they show that <strong>increased potassium intake leads to a reduction in blood pressure among individuals with hypertension.<\/strong> Additionally, this reduction also lowers the risk of stroke by as much as 24%. The findings suggest that increasing potassium intake has beneficial effects on<strong> heart and vascular health.<\/strong> However, this applies only to individuals with healthy kidneys, which can adequately excrete excess potassium and prevent its accumulation in the body. <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup> [8, 11]&nbsp;<\/sup><\/mark><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">What dietary changes can help lower blood pressure?<\/h4>\n\n\n\n<p>For those looking to adjust their diet to prevent hypertension, the DASH diet (Dietary Approaches to Stop Hypertension) is recommended.

It supports the excretion of excess sodium, <strong>preventing water retention in the body<\/strong> and thereby easing the burden on the kidneys. Studies suggest that adequate potassium intake is also associated <strong>with a lower risk of developing kidney stones.<\/strong> This is largely due to potassium&#8217;s ability, particularly in the form of potassium citrate, to bind with calcium, preventing the accumulation and formation of calcium stones. Additionally, potassium aids the kidneys in <strong>maintaining acid-base balance by<\/strong> participating in the excretion of excess acids. Thus, optimal potassium levels in the body rank among the factors that help keep the kidneys healthy. <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[1, 9]<\/sup><\/mark><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"bones\">3.

Experts explain that <strong>potassium helps decrease acidity in the body,<\/strong> keeping pH at optimal levels. Without potassium&#8217;s role in this process, calcium would have to combat the acidic environment, leading to <strong>unwanted calcium depletion from the bones.<\/strong> This could ultimately result in conditions such as osteoporosis, also known as bone thinning. <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[16]<\/sup><\/mark><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Conclusions from several studies also indicate that adequate potassium intake is associated with<strong> improved calcium absorption<\/strong> from the diet and<strong> promotion of bone mineralization.<\/strong> Some experts also mention a potential <strong>positive effect of potassium on the conversion of vitamin D<\/strong> into its active form, which is no less important for bone health. <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup> [17]<\/sup><\/mark><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1124\" height=\"749\" src=\"https:\/\/gymbeam.cz\/blog\/wp-content\/uploads\/2024\/09\/a58229a0-4be2-4f48-8e31-5cc2317918e0-1124x749.jpg\" alt=\"The benefits of potassium\" class=\"wp-image-613771\" title=\"The benefits of potassium\" srcset=\"https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/a58229a0-4be2-4f48-8e31-5cc2317918e0-1124x749.jpg 1124w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/a58229a0-4be2-4f48-8e31-5cc2317918e0-400x267.jpg 400w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/a58229a0-4be2-4f48-8e31-5cc2317918e0-1536x1024.jpg 1536w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/a58229a0-4be2-4f48-8e31-5cc2317918e0-2048x1365.jpg 2048w\" sizes=\"auto, (max-width: 1124px) 100vw, 1124px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"blood-sugar\">4.

Without it, we wouldn&#8217;t be able to spring into action for a squat or a jump at a moment&#8217;s notice. Potassium<strong> enables us to react swiftly to unexpected stimuli,<\/strong> like catching a ball thrown our way. This quick reflex is what we call reaction speed.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>During athletic performance, potassium shifts <strong>from the cells into the intercellular space.<\/strong> This transfer is essential for <strong>neuromuscular transmission<\/strong> and, consequently, muscle contraction. However, this rapid exit of potassium from the cells can lead to a deficiency. Combined with losses through sweating, this further exacerbates the potassium deficit. As a result, we may notice <strong>diminished muscle function and quicker onset of fatigue<\/strong> during training. A serious potassium deficiency can manifest as<a href=\"https:\/\/gymbeam.com\/blog\/muscle-cramps-how-to-prevent-and-relieve-them\/\"> <strong>muscle cramps<\/strong><\/a> and, in extreme cases, even heart rhythm disturbances (arrhythmia). <mark class=\"has-inline-color has-orange-color\" style=\"background-color: rgba(0, 0, 0, 0);\"><sup>[13\u201315]<\/sup><\/mark><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Endurance athletes<\/strong> are particularly at risk of reduced performance due to low potassium levels.

They are a good option if you want to increase your intake of this micronutrient.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1124\" height=\"749\" src=\"https:\/\/gymbeam.cz\/blog\/wp-content\/uploads\/2024\/09\/iStock-1153773419-1124x749.jpg\" alt=\"Potassium and cooking\" class=\"wp-image-613901\" title=\"Potassium and cooking\" srcset=\"https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/iStock-1153773419-1124x749.jpg 1124w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/iStock-1153773419-400x267.jpg 400w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/iStock-1153773419-1536x1024.jpg 1536w, https:\/\/gymbeam.com\/blog\/wp-content\/uploads\/2024\/09\/iStock-1153773419-2048x1366.jpg 2048w\" sizes=\"auto, (max-width: 1124px) 100vw, 1124px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">2. Potassium in dietary supplements<\/h3>\n\n\n\n<p>Potassium supplements are ideal<strong> for athletes who experience higher losses through sweat.<\/strong> They can also benefit individuals who don&#8217;t regularly consume foods rich in this nutrient. Dietary supplements with potassium come in various forms, such as potassium chloride, citrate, phosphate, aspartate, carbonate, or gluconate. This raises the question: <strong>\u201cWhich form of potassium is best?\u201d<\/strong> Studies indicate that all forms have similar absorption rates, so you don&#8217;t need to worry too much about this.
