8 Foods That Contain Electrolytes

8 Foods That Contain Electrolytes

When you think of electrolytes, you most likely think of brightly colored sports drinks sold in supermarkets, convenience stores, and gas stations. In reality, these sports drinks contain a hefty amount of sugar, dyes, added flavors, and preservatives. You get more sugar than electrolytes when you consume them.

What Are Electrolytes?

Electrolytes are essential minerals, including calcium, sodium, chloride, magnesium, phosphate, and potassium. The term “electrolytes” refers to particles that carry positive or negative electric charges. From a nutritional standpoint, these are the vital nutrients in your sweat, blood, and urine. When potassium, sodium, or calcium dissolve in a fluid, they form electrolytes, which are positive or negative ions in metabolic processes. Electrolytes are necessary to keep the nervous system and muscles functioning. They also help to balance your internal environment.

Although drinking electrolyte-rich beverages can help fuel the body, they aren’t the only sources. You can find a variety of electrolytes in various fruits and vegetables, the top eight of which we detail below. 

Coconut Water

Coconut water refers to the clear liquid found within a young, green coconut. Some scientists refer to it as nature’s sports drink because it exhibits an impressive electrolyte composition. Coconut water offers potassium, magnesium, sodium, and calcium, all of which play critical roles in maintaining hydration, ensuring muscle and nerve function, and regulating heart function. 


Watermelon is the quintessential fruit of summer. Not only is it refreshing and hydrating, but it is a great natural source of electrolytes. Watermelon contains potassium, a small amount of sodium, and magnesium. Those electrolytes aid with muscle function, balancing bodily fluids, and hydration. Watermelon is also rich in other nutrients, such as vitamins A and C and lycopene, which is an antioxidant beneficial for heart health. 


Just like watermelon, tomatoes also contain lycopene, which gives them their signature red color. Tomatoes are often underestimated as a hydrating fruit, but they are naturally rich in water and electrolytes. They are great sources of potassium, which is vital for muscle contractions, nerve function, and fluid regulation. Additionally, tomatoes contain magnesium, sodium, and other antioxidants that support overall health. 


Strawberries are known for their great taste and impressive antioxidant content, but they also provide several electrolytes. They contain potassium, which helps nerve signaling and heart function. Strawberries also provide magnesium, which works to regulate blood sugar levels and supports muscle and nerve function. 


These small but mighty nuts may cost a pretty penny, but they are oh so worth it. Pistachios contain magnesium, and potassium, both of which support nerve signal transmission and blood pressure regulation. In addition to the electrolytes they provide, pistachios offer healthy fats and antioxidants. That makes these nuts a great addition to any balanced nutrition program. 

Spinach And Kale

Yet another reason to eat leafy greens, kale and spinach offer lots of magnesium and potassium. These two electrolytes work to regulate blood pressure and support overall heart function. Spinach has a mild flavor, so you can incorporate it into a variety of dishes. Kale tends to have a slightly bitter flavor, but you can tame that if you combine it with the right ingredients. Kale also offers calcium, which supports healthy bones and teeth, in addition to heart function.


People praise avocados for their healthy fat content, but they also contain a couple electrolytes: potassium and magnesium. They even contain more potassium than bananas! Both magnesium and potassium work to maintain fluid balance, muscle contractions, and nerve signals. Finally, the healthy fats in avocados are essential for the absorption of fat-soluble vitamins and provide slow-burning fuel for the body. 


Oranges are naturally rich in vitamin C, but they also contain potassium and calcium. That combination of nutrients makes oranges great for maintaining hydration and overall health. While potassium contributes to optimal heart function and nerve signaling, calcium supports bone health and has a hand in nerve transmission and muscle function. To reap these benefits, make sure you consume fresh oranges or freshly squeezed orange juice. Do not just consume store bought orange juice and think that you will get the same benefits, because you won’t.
