Potassium
articles
Potassium is an essential mineral and electrolyte. You need to get potassium from your diet and withoutenough potassium, bodily functions related to heart health, muscle and nerve function, fluid balance and pH maintenance, and even the synthesis and metabolism of nutrients can’t occur properly. A dietary shortfall in potassium can lead to negative health effects over time, so it’s important to get the recommended 2600–3400 mg per day. Our product includes 90 mg per day to help supplement your diet towards that goal.
If you’re wondering what does potassium do for your body, it’s a key player in many critical functions that work to keep us healthy. Three of the main benefits of getting enough potassium are discussed below.
Potassium is the main electrolyte in your intracellular fluid, which resides inside your cells and accounts for forty percent of the water found in your body. Working alongside sodium, potassium determines fluid balance, or how much water is inside and outside your cells at any given time. [1]
When the number of electrolytes inside and outside of your cells is balanced, this is called having normal osmolality. If osmolality is abnormal, this fluid imbalance can cause cells to shrink and burst, which can lead to health conditions. [2]
Potassium supports heart function by helping to control the activity of the heart muscle. Having enough potassium is necessary for healthy nervous system signals and normal muscle contraction. The movement of potassium in and out of your cells supports a regular heartbeat.
The involvement of potassium in nerve and muscle function means that imbalances can impair these normal processes in the body. Nerve impulses, which help regulate heartbeat, muscle contractions, and reflexes, occur when sodium moves into cells and potassium moves out of cells. [3]
Having too low or too high levels of potassium can alter the voltage of nerve cells throughout the body. For instance, if potassium levels drop too low, this may have a negative impact on your body.search has demonstrated the importance of getting enough potassium for heart health, particularly in relation to sodium intake. Research has shown the importance of following dietary patterns that are rich in potassium and low in sodium for heart health. Specifically, the DASH trial showed that a diet higher in potassium and lower in sodium, saturated fat and added sugars supported healthy blood pressure. Those on the DASH diet consume about 4,000 mg potassium/day and 8 servings of fruits and vegetables. [10] For heart health and to counteract the effects of excessive intake of sodium in the diet, professional organizations recommend no more than 2,300 mg/day of sodium and 4,700 mg/day potassium.
While it’s a nutrient on its own, potassium is also involved in larger nutrition-related processes in the body. It helps synthesize proteins as well as metabolize carbohydrates, both of which are essential macronutrients for health, growth, and energy.
Other research suggests that decreased intracellular potassium slows the rate of cell growth because of how it impacts protein synthesis. [5, 6]
Now that we’ve covered what does potassium do for your body, you’re probably wondering how much of this mineral you need.
There isn’t enough evidence to establish a recommended dietary allowance (RDA) for potassium, so instead there are adequate intakes (AI) for this mineral. AIs indicate the daily amount presumed to be enough to ensure nutritional adequacy for healthy individuals.
Below is a list of AIs for potassium based on sex and age: [7]
If you have kidney function issues, be sure to speak with your healthcare provider before supplementing.
Potassium is considered a shortfall nutrient. What this means is that a high percentage of the population is not consuming enough of an essential nutrient in their diet to meet recommended daily amounts. The latest Dietary Guidelines for Americans list potassium as a “nutrient of public health concern” since a dietary shortfall of this nutrient is associated with adverse health effects, including heart health concerns. Women of childbearing age, especially, are not consuming enough potassium since 68% of women ages 31-44 years and over 66% of women ages 15-30 years have an inadequate intake of potassium in their daily diet. Even more concerning, only about 2% of Americans overall are meeting daily potassium recommendations as set by professional health organizations (4700 mg per day)[8,9]. Because of inadequate daily potassium intake among so many Americans, the Food and Drug Administration required manufacturers to include potassium content on the Nutrition Facts food label [7]. Potassium deficiency is uncommon and requires a blood test to confirm levels. Speak with your healthcare provider if you have questions about the test.
Knowing what does potassium do for your body is one thing, while understanding where it’s found is another. Potassium is found in many types of foods that are easy to incorporate into meals and snacks, especially those listed below.
Some of the most potassium-rich fruits are bananas, cantaloupes, cherries, oranges, tomatoes, and watermelons. Enjoy fruits as a snack on their own, as a topping for cereal, oatmeal, pancakes, or yogurt, or blended into smoothies.
Avocados, beets, carrots, mushrooms, potatoes, spinach, parsley, broccoli, and Brussels sprouts are great sources of potassium. Vegetables can be eaten raw with a creamy dip, roasted in the oven, pureed into sauces, or cooked in soups and casseroles.
In addition to foods, you can also find some potassium in orange juice, milk, coffee, and certain types of non-dairy milk. Check the label to see how much potassium is provided per one-cup serving.
Beans are a nice meat alternative and can offer up to a whopping 1800 mg of potassium in just a half-cup serving. Peas and lentils, as well as nuts like almonds, walnuts, and cashews, are also good sources that you can add to soups, salads, casseroles, or grain dishes.
If you’re not sure where to start, try to include at least two or three servings of potassium-containing foods at a meal.

The best place to find potassium is in whole foods like the ones listed above, as these foods also offer other health benefits. However, if a potassium-rich diet is not feasible, a potassium supplement may be helpful to make sure you’re meeting the AI for this nutrient.
Note that if you take a multivitamin with minerals, these generally include approximately 99 mg of potassium in them already. While this is only a small portion of the AI for potassium, check the label before adding another source of supplemental potassium. Always speak to your doctor before adding a potassium supplement, or other dietary supplements, to your routine to make sure that it’s safe and appropriate for you to do so.
Potassium supplements can come in forms like powders, capsules, liquids, and tablets. The most common forms include potassium chloride, potassium citrate, potassium gluconate, potassium phosphate, potassium bicarbonate, and potassium aspartate. There is no strong evidence that one form is better than the others. [7] Nature Made Potassium Gluconate 550 mg contains 90 mg of potassium, which helps control the normal activity of the heart, muscle, and nerve function.†
Potassium is a critical nutrient for numerous bodily functions, and many of us aren’t getting enough of it in our diets. Fortunately, it’s easy to find in foods like fruits, vegetables, nuts, legumes, and certain beverages. If you don’t eat a potassium-rich diet or are concerned about your intake, speak to your doctor about adding a potassium supplement.
