    A silver-white soft light low-melting monovalent metallic element of the alkali metal group that takes place perfectly in nature particularly combined in minerals. [1]

    The essentials of potassium

    Potassium is a vital mineral that is required by all tissues in the body. It is sometimes described as an electrolyte due to the fact that it carries a little electrical charge that activates different cell and nerve functions. Potassium is discovered naturally in many foods and as a supplement. Its main function in the body is to assist keep regular levels of fluid inside our cells. Salt, its equivalent, maintains typical fluid levels beyond cells. Potassium likewise helps muscles to agreement and supports regular blood pressure. [2]


    Potassium salts in the form of saltpeter (potassium nitrate, KNO3), alum (potassium aluminum sulfate, KAl( SO4) 2), and potash (potassium carbonate, K2CO3) have been known for centuries. They were used in gunpowder, coloring, and soap making. They were scraped from the walls of latrines, made from clay and sulfuric acid, and gathered as wood ash respectively. Decreasing them to the element defeated the early chemists and potassium was classified as an ‘earth’ by Antoine Lavoisier. Then in 1807, Humphry Davy exposed damp potash to an electric existing and observed the formation of metal globules of new metal, potassium. He kept in mind that when they were dropped into water they skimmed around on the surface, burning with a lavender-coloured flame. [3]

    Mechanism of action

    Potassium ion is the main intracellular cation discovered in essentially all body tissues. The total amount of body potassium in grownups is approximated at 45 millimole (mmol)/ kg body weight (about 140 g for an adult weighing 175 pounds; 1 mmol = 1 milliequivalent or 39.1 mg of potassium). Potassium generally remains in cells, and a percentage can be discovered in the extracellular fluid. The quantity of potassium that remains in the cell (intracellular) is 30 times that of extracellular concentration, creating a trans membrane gradient, managed by the sodium-potassium (Na+/ K+) ATPase transporter. This is an essential gradient for nerve conduction, contraction, and renal function. Throwing up, diarrhea, renal illness, medications, and other conditions that modify potassium excretion or move it inside or beyond cells. In healthy patients’ individuals with typical renal function, considerably high or low potassium levels are uncommon.

    Effect on blood pressure

    Potassium reduces lowers intravascular volume, by minimizing salt reabsorption through a boost in urinary salt excretion. This short-term result, nevertheless, does not explain the long-lasting effects of potassium on high blood pressure. Increased plasma potassium levels that happen through intake are connected with vasodilation taking place by means of stimulation of the sodium-potassium adenosine triphosphatase pump (Na+/- K+ATP ase) and opening of potassium channels of the sodium-potassium adenosine triphosphatase pump. Other possible mechanisms of action for potassium may include changes in barroreflex level of sensitivity and hormonal agent sensitivity in vascular smooth muscle and cells of the sympathetic nervous system.

    Result on electrolyte balance and body systems

    The potassium gradient throughout the membrane of a cell manages cell membrane capacity, kept predominantly by the sodium-potassium (Na+/- K+ ATPase pump). Transmembrane electro-chemical gradients encourage diffusion of Na+ extracellularly and K+ intracellularly. Potassium supplementation prevents hypokalemia to maintain this balance and is often utilized in an oral option or injection type in the medical setting, preventing hazardous results such as arrhythmias, irregular muscle function, and neurological disturbances. When triggered, the Na+/- K+ ATPase pump exchanges two extracellular K+ ions for 3 intracellular salt (Na+) ions, impacting membrane potential via either excitation or inhibition. This is especially crucial in the homeostasis of the nervous system, kidney, and cardiac muscle tissue. The body and cell circulations of potassium in normal conditions are referred to as internal and external balance, respectively. Reduced serum potassium (or imbalance) increases the risk of ventricular arrhythmia, cardiac arrest and left ventricular hypertrophy (LVH). [4]

    Health Advantages of Potassium

    It is frequently considered a necessary nutrient that cures blood pressure, minimizes stress and anxiety and tension, and enhances a lot more health disorders. Let’s have a look at the typical benefits in detail.

    Stimulates Neural Activity

    It plays a crucial role in keeping brain function at a typical level. High levels of potassium permit more oxygen to reach the brain, consequently stimulating neural activity and increasing cognitive function. There is a great reason that people call bananas brain food; they include remarkably high levels of this mineral.

    It is of terrific value in preventing the event of stroke in the human brain. Dr. Elizabeth Barrett-Connor and Kay-Tee Shaw, M. Sc., through their research, found that a high intake of potassium from food sources might protect versus stroke-associated death. It is no secret that people at high risk for this terrible condition are frequently discovered to be deficient in this vital nutrient. Considering that it serves as a vasodilator, the capillary relax throughout the body when an appropriate quantity of this mineral is taken in. This indicates that blood flows more easily and is less most likely to clot and break off to trigger strokes.

    Stabilizes Blood Sugar Level

    Studies recommend that lower levels of potassium are associated with a higher threat of diabetes. A study released by a group of researchers from Johns Hopkins University, Baltimore, U.S.A., found a link in between high levels of insulin/glucose and low levels of potassium in individuals who were otherwise considered to be healthy. This is likewise why those struggling with diabetes are encouraged to keep their potassium levels regular, to lower the possibilities of unpredictable spikes and plunges in their glucose and insulin levels by stabilizing the blood sugar level levels throughout the body. Medical professionals consider low levels of potassium with high levels of insulin as attributes of developing diabetes.

    Minimizes Muscle Disorders

    An adequate concentration of this mineral is needed for the regular contraction and relaxation of muscles. The majority of the potassium ions in the human body lie in the muscle cells. It preserves ideal muscle and nerve function and helps keep our reflexes fast due to the fact that it stimulates the neural connection of muscles and the brain.

    Avoids Cramps

    Muscle cramps are a typical outcome of low levels of potassium in the blood, a condition called hypokalemia (source: Journal of Athletic Training). If you consume a banana every day, you can quickly avoid muscle cramps because bananas have abundant potassium content.

    Improves Bone Health

    The advantages of potassium even encompass improving the health of your bones. There are particular qualities of this mineral that reduce the effects of different acids in the body, which helps in retaining and preserving calcium, making it accessible to utilize for bone strength and durability. Moreover, a study at the Linus Pauling Institute Micronutrient Information Center states that eating vegetables and fruits having high levels of this mineral leads to greater mineral density in bones, further enhancing and extending their life.

    Manages Neural Function

    Potassium channels play a key function in preserving the electrical conductivity of the brain and considerably impacting the brain function. It is likewise involved in greater brain function like memory and knowing. In addition to this, ailments like epilepsy relate to the dysfunction of potassium channels that can happen through its deficiency. There are potassium currents that play a significant role in mammalian nerve cells. These channels are interconnected with a huge selection of neural function and can help moderate and manage electrical currents throughout the body.

    Stabilizes Blood Pressure

    Potassium is valuable in reversing the role of sodium in unbalancing regular high blood pressure, as researched by Cappuccio Francesco P et al. published in the Journal of High blood pressure. Therefore, it acts as a vital component that preserves the normality of blood pressure in the human body. This more lowers the danger of heart diseases and high blood pressure. Regulation of high blood pressure is one of the most important functions of this effective mineral. As mentioned earlier, it has vasodilation homes that work to eliminate the tension of capillary, which is among the primary causes of high blood pressure.

    Enhances Muscles

    One of the useful benefits of potassium is its function in ensuring the appropriate development of muscle tissues and the utilization of energy launched throughout metabolic process, which includes significantly to muscular strength. The muscles, consisting of those all-important heart muscles, are prone to paralysis due to a deficiency of potassium in a person’s diet plan.

    Promoting cell growth and offering the metabolic energy to do so is an important function of potassium and muscular health would be compromised without it. Also, without the contraction and relaxation that potassium allows muscles to perform, exercise and extra muscle training would be impossible.

    Improves Metabolism

    Potassium helps in the metabolic processing of various nutrients like fats and carbs. Thus, it is of a terrific worth in extracting energy from the nutrients that are consumed. In-depth research studies carried out in Denmark have actually revealed that this mineral is likewise an important part of the synthesis of protein, which has an impact on tissue regrowth, cell development, and general balanced metabolism.

    Lowers Anxiety & Tension

    Potassium is of terrific value for people struggling with undesirable mental states like stress and anxiety and tension. It is thought about an effective stress buster and for that reason, guarantees an efficient mental performance. Stress and anxiety and stress are very destructive to other parts of the health and any bonus offer from things like potassium is considered an excellent concept if you struggle with chronic tension. This mineral can help control numerous hormonal agents in your body, consisting of tension hormones like cortisol and adrenaline, excess amounts of which can be damaging to the body.

    Enhances Heart Health

    The health advantages of potassium ensure health for the heart along with the kidneys. It plays an irreplaceable function in controling the metabolism and keeping the heart and kidneys running smoothly. Furthermore, this mineral helps the kidneys in getting rid of waste through the procedure of excretion. Nevertheless, it is strongly encouraged to consult your physician to get recommendations about potassium dosage, due to the fact that it can assist promote the body to soak up more calcium than required, which can in fact calcify and trigger kidney problems, instead of solve them.

    Maintains Water Balance

    Another significant role that potassium plays remains in the upkeep of an optimum fluid balance in the body. Different types of cells need a correct water balance for efficient performance and potassium help these cells in managing the balance. Fluid balance keeps all of our organ systems functioning in one method or the other, which is why many people suggest consuming bananas after athletic events or after a night of heavy drinking, in order to rehydrate and enhance fluid balance.

    Manages the Level of Fluids

    Potassium is also a fantastic electrolyte in the human body. It helps in managing the level of fluids in the body and hence help in a variety of important body functions. Moreover, electrolytes help send electrical charges throughout the body from the brain and nerve system, so extra electrolytes keep everything functioning faster.

    Enhances Nerve System

    Potassium assists increase the effectiveness of nerve reflexes that send the message from one body part to another. This, in turn, assists in muscle contraction to perform various activities every day without getting tired quickly, which is additional benefited by potassium and is needed to induce muscle contraction and function.

    Word of Caution: Excess of this mineral in the body can be hazardous; for instance, patients with kidney issues who can not appropriately process this mineral, may have precariously high levels. This can result in heart problem, muscle paralysis, bothered breathing, tingling in the hands and feet, heart arrhythmia, and queasiness. Potassium can be an amazing addition to specific diets, however always take care that you do not exaggerate, and if you choose to include potassium supplements in your diet, consult your doctor initially. [5]


    People with irregular kidney function and those on potassium-sparing medications or ACE inhibitors, which are generally utilized for dealing with high blood pressure, might require to monitor their intake of potassium and probably should not be on a potassium supplement. If for some reason your healthcare provider has suggested this anyhow, your blood will be kept an eye on carefully to prevent hyperkalemia (high blood potassium).

    If you’re taking specific medications, you ought to avoid taking potassium supplements. These kinds of medications consist of spironolactone, triamterene, amiloride, captopril, enalapril, fosinopril, indomethacin, ibuprofen, ketorolac, trimethoprim-sulfamethoxazole, pentamidine, heparin, digitalis, β-blockers, α-blockers, losartan, valsartan, irbesartan, and candesartan.

    Whenever you have a question about potential interactions, consult your doctor.

    Water Tablets Undermine Potassium

    Individuals who take water tablets (also called diuretics) are often recommended potassium at the same time. This due to the fact that as the body gets rid of extra fluid, it likewise flushes out electrolytes like potassium.

    Meet Your Potassium Requirements

    The ideal way to satisfy your potassium requires is to eat a variety of whole foods consisting of fruits like avocados, oranges, bananas, vegetables (such as sweet potatoes, squash, and dried beans), low-fat milk, and specific sources of protein like salmon and chicken.

    It is no knock on supplements to say that food is your very best source of nutrition. (After all, they’re called “supplements” for a factor: They’re planned to supplement what’s missing out on from your food diet.) Besides, it’s approximated that the body takes in about 85 to 90 percent of dietary potassium.

    If you have actually had trouble adding fresh fruit and vegetables to your diet plan, think about including frozen vegetables and fruits. Food is frozen at peak freshness, improving its dietary value.

    Many individuals associate bananas with potassium. But a few other fruits actually consist of more potassium than bananas. It can be enjoyable to find out which ones.

    Foods High in Potassium

    According to the USDA nutrition database, the following are foods high in potassium. See listed below for a list of these foods followed by the quantity of potassium each contains:.

    • Acorn squash (1 cup cooked without salt): 896 milligrams
    • Apple (1 medium with skin): 195 milligrams
    • Artichokes (1 cup hearts prepared): 480 milligrams
    • Avocado (1/4 of the whole): 172 milligrams
    • Banana (1 medium): 430 milligrams
    • Beets (1 cup raw): 442 milligrams
    • Broccoli (1 cup chopped and cooked): 457 milligrams
    • Child Brussels sprouts (13 pieces): 315 milligrams
    • Beans (1/2 cup dried– quantities differ based on variety): 1,813 milligrams
    • Cantaloupe (1 cup cubes): 427 milligrams
    • Carrots (1 cup sliced): 410 milligrams
    • Cherries (1 cup without pits): 342 milligrams
    • Milk (1 cup low-fat): 350-380 milligrams
    • Mushrooms (1 cup whole): 305 milligrams
    • Orange (1 little): 238 milligrams
    • Peas (1 cup raw): 354 milligrams
    • Peppers (1 cup chopped): 314 milligrams
    • Parsley (1 cup chopped): 332 milligrams
    • Potato (1 medium baked with skin): 930 milligrams
    • Quinoa (1 cup cooked): 318 milligrams
    • Salmon (6 ounces): 730 milligrams
    • Spinach (1 cup prepared): 839 milligrams
    • Sweet potato (1 cup baked ): 664 milligrams
    • Tomatoes (1 cup chopped): 430 milligrams
    • Watermelon (1 cup diced): 170 milligrams

    Compared to a control diet plan (offering 3.5 servings a day of vegetables and fruits and 1,700 milligrams per day of potassium), eating a diet that included 8.5 portions each day of fruit and vegetables and 4,100 mg daily of potassium has actually been shown to lower blood pressure. Research studies have also found that eating more fruits and vegetables (foods naturally rich in potassium) can minimize high blood pressure.

    Go into Yogurt

    Plain, nonfat yogurt is a great source of potassium, packaging 625 milligrams of potassium in a 1-cup serving.

    Processed Foods

    Some processed and packaged foods likewise include added potassium salts or naturally happening potassium (such as dried beans and whole grains). If you should monitor your potassium consumption, bear in mind labels. The majority of active ingredient labels will list “potassium chloride” as an additive. This is normally found in foods such as cereal, snack foods, frozen foods, processed meat, soups, sauces, treats, and meal bars.

    You may also discover included potassium in products such as Emergen C (a powdered drink). Foods which contain a minimum of 350 milligrams per serving are permitted by the FDA to state, “Diet plans including foods that are excellent sources of potassium and low in salt might decrease the danger of high blood pressure and stroke.” [6]

    How can I get more potassium in my life?

    Easy– simply eat foods high in potassium. While bananas are frequently promoted as a potassium powerhouse– and with 422 milligrams per medium fruit, it does have a good quantity– it’s not the just excellent source. Two cups of spinach has 334 milligrams of potassium, one cup of Brussels sprouts has 389 milligrams, and one cup of lentils has a whopping 731 milligrams.

    If you do want to stick to fruits, one cup of cubed cantaloupe has 427 milligrams, one cup of dried apricots has 1,720 (!) milligrams, and one cup of oranges has 326 milligrams– making them all terrific sources.

    However, while loading up on potassium-rich foods is generally not an issue for the majority of healthy individuals, getting too much potassium can be a problem for individuals who have kidney problems, Aaron says. Your body’s potassium is processed in the kidneys; if your kidneys aren’t working appropriately, your body may have a tough time filtering out the excess. “Those with impaired kidney function should consult their physician about going on a potassium-restricted diet plan if potassium build-up is an issue,” Aaron states.

    It’s clear that potassium is significantly essential to the body, and thankfully, it’s not too difficult to get enough of this important nutrient– and doing so can be scrumptious! If you are fretted about your potassium levels, book an appointment with your physician who can do blood work ensuring your levels are where they ought to be. And hi, possibly pack a banana to eat on your way home. [7]

    Adverse effects

    When taken by mouth: Potassium is likely safe for the majority of people when taken by mouth in amounts of approximately 100 mEq (3900 mg) of total potassium daily. In some people, potassium can trigger stomach upset, nausea, diarrhea, vomiting, or digestive gas.
