Does Coffee Have Potassium? Your Question Answered Below!

Coffee and Potassium 

You may be wondering, does coffee have potassium? Potassium is a micronutrient that is necessary for the proper functioning of cells. It has a high degree of reactivity in water and produces positively charged potassium ions. 

These ions contribute to the body’s ability to carry electrical impulses throughout its entirety. This is essential for a wide variety of bodily processes. You’ll find approximately 98% of the body’s total potassium inside the cells.

Does Coffee Have Potassium?

Does coffee have potassium in it? Coffee is a good source of potassium. Every 3.5 ounces (100 grams) serving of coffee has a potassium content of 0.002 ounces (0.045 grams). This results in the food having a low potassium content. If you consume more than three cups of coffee daily, it raises potassium levels in the body. 

The addition of creamers or milk can result in an even greater rise in the potassium level of the coffee. It may be the same case for tea. Therefore, daily consumption of 0.17 ounces (4.7 grams) of potassium is a recommendation for optimal health and proper operation of the body’s systems. 

Coffee high in potassium can lessen the chance of a stroke, reduce the risk of developing kidney stones, lower blood pressure, and keep muscles from cramping. Potassium is present in many wholes, unprocessed foods, including fresh leafy greens, avocados, tomatoes, potatoes, and beans. 

A low potassium level (known medically as hypokalemia) and high potassium in coffee (known medically as hyperkalemia) can lead to dangerous conditions and even threaten one’s life.

Is Coffee Bad for Your Kidneys?

The first thing that many people do when they get up is make themselves a coffee cup and settle in for the day. Caffeine in coffee gives us a surge of energy, allowing us to tackle the challenges of the day.

How Much Potassium Can I Have?

As an adult with kidneys that are working properly, you should consume approximately 0.16 ounces (4.5 grams) of potassium daily. And this is something that is typically not too tough to accomplish with a regular diet.

The Adequate Intakes of potassium, as determined by the National Institutes of Health, range from 0.08 to 0.12 ounces (2.3 to 3.4 grams) daily. This amount differs depending on the person’s gender and age.

On the other hand, a person afflicted with renal (kidney) disease would typically need to adhere to a potassium-restricted diet of approximately 0.07 ounces (2 grams), which can be challenging given the abundance of foods containing potassium.

Is There Potassium in Tea?

It is common knowledge that tea is one of the most beneficial beverages regarding its positive effects on one’s health. Is it true that tea also contains a lot of potassium? If you drink a lot of tea, you need to be aware of the potential adverse effects of either a lack of potassium or a high potassium level on your health.

If you are following a diet low in potassium, it is usually okay to consume tea as it contains very little potassium. Although the potassium concentration of different types of tea might differ significantly from one another, on average, tea has a very low potassium content.

The amount of tea potassium varies depending on the type of tea that you consume. For example, one serving of 8 ounces (226.8 grams) of black tea contains 0.003 ounces (0.09 grams) of potassium (less than 2 percent of the necessary daily consumption). 

One serving of 8 ounces (226.8 grams) of green tea provides around 0.0007 ounces (0.02 grams) of potassium, and one cup of herb tea includes approximately 0.0007 ounces (0.021 grams) of potassium. 

You will immediately be able to determine which type of tea is best for you to drink, depending on whether you want to increase or decrease the amount of potassium you consume. 

The amount of potassium that a healthy adult should consume daily is between 0.12 and 0.17 ounces (3.5 and 4.7 grams). On the other hand, the recommended daily consumption of potassium for a low-potassium diet is between 0.07 and 0.11 ounces (2 and 3 grams).

The Benefits of Potassium

The following are some of the bodily processes that benefit significantly from potassium’s presence:

Maintains Fluid and Electrolyte Balance

The human body has roughly 60 percent water, of which 40 percent is inside the cells in the intracellular region and is the intracellular fluid (ICF). You can find the remainder of the fluid outside the cells in the extracellular space (such as the blood) and the spaces between the cells. 

The term “extracellular fluid” can also refer to this fluid (ECF). Electrolytes, primarily potassium and sodium, are responsible for maintaining the correct fluid balance between the ICF and ECF. Because potassium is the primary electrolyte found in the ICF, it is responsible for controlling the amount of fluid found inside the cells. 

Since sodium is the primary electrolyte found in the ECF, it is responsible for regulating the quantities of fluid found outside of the cells. When there is an imbalance in the amounts of electrolytes, the cells either contract or enlarge and explode. Therefore, consuming a suitable quantity of fluids and electrolytes, particularly potassium, is necessary to keep organs healthy.

Maintains the Nervous System

It takes care of the nervous system, responsible for transmitting messages between the brain and the rest of the body. Potassium ions are responsible for transmitting electrical impulses down the nerves, which is how the body controls muscle contractions, nerve reflexes, and other bodily activities. 

It is the movement of sodium ions into the cells and the movement of potassium ions out of the cells that results in the production of nerve impulses.

Regulates Muscle Contractions, Including the Heart

Potassium is necessary for muscle contraction, including the process that occurs in the heart and gut muscles.

How to Protect Your Kidneys Against Too Much Coffee

It is essential to have enough information on coffee and kidneys. Coffee is not harmful to people who enjoy drinking it, but there are a few things you should keep in mind to protect your kidneys from the effects of drinking too much coffee:

The Amount of Coffee You Consume

The first thing you should consider is the nutritional profile of coffee. In a cup of 8 ounces (226.8 grams) in size, there are 0.004 ounces (0.11 grams) of potassium as black coffee. This item has a relatively low potassium concentration overall. Despite this, many people drink more than one cup of coffee daily.

It is advisable to consume three to four cups of coffee each day, which is high in potassium and may cause your potassium levels to rise. Adding creamer or milk to your coffee can bring the total amount of potassium it contains up to an even higher level.

Generally, we consider any amount of coffee consumed daily that is lower than three cups risk-free. The nutritional value of black coffee is almost null due to its low levels of phosphorus, salt, calories, carbohydrates, and protein.

Your Fluid Intake

You should count coffee as one of the fluids in your daily consumption. You should count coffee toward your daily fluid quota if you are only allowed a certain amount of liquid consumed daily. 

In conclusion, those with kidney issues can drink coffee without adverse effects. When consumed in moderation, it poses a minor threat to individuals who already have kidney disease.

You can increase the potassium and phosphorus in coffee by consuming it with milk and various creamers. People who are unsure how much coffee is appropriate for them should discuss the matter with a trained dietitian or a licensed medical practitioner.


The things added to coffee are frequently the source of more problems than the coffee itself. For example, an 8 ounces (226.8 grams)cup of plain cafe latte contains 0.012 ounces (0.3 grams) of potassium and 0.007 ounces (0.19 grams) of phosphorus. These amounts depend on the absence of flavored syrup. 

Creamers are another potential source of problems. Chemical phosphates are frequently included in coffee creamers by their makers. Patients with kidney conditions should try to consume as little of these chemical phosphates as possible because the body rapidly absorbs them.

Should You Drink Coffee When You’ve Got Kidney Diseases?

Coffee is a fluid. If you are on a diet that limits the number of liquids you consume each day, you should still allow yourself to drink coffee.

In conclusion, coffee is a drink that those with kidney illnesses should not avoid. Those who already have kidney illness aren’t likely to be adversely affected if they ingest it in moderation. People who drink coffee but aren’t sure how much of it is healthy for them should consult a qualified dietitian or a physician about the quantity that’s right for them.
