Does Orange Juice Have Electrolytes? How Much?

Orange Juice contains electrolytes like potassium and magnesium, which help maintain fluid balance. 

Recent research suggests that 100% orange juice is a better choice for hydration than many other beverages. A clinical study found that drinking OJ after exercise is just as hydrating as water or sports drinks, making it a healthy option for post-workout recovery.

For older adults, experts recommend consuming 100% fruit juice to maintain fluid intake and prevent dehydration while meeting food group recommendations.

Why is Hydration Important?

100% orange juice is mostly water, accounting for almost 90% of its content. Water is essential for your well-being as it constitutes the major part of all cells. It helps in the flow of fluids like oxygenated blood inside the cells, and plays a vital role in numerous cellular processes. 

Having enough water is crucial for the body to maintain its optimal function, including controlling body temperature, managing blood pressure, and carrying nutrients throughout the body. Sufficient hydration can also enhance the appearance of healthy skin by augmenting skin elasticity.

What are Electrolytes?

Electrolytes are essential nutrients that include potassium, sodium, magnesium, and calcium. These nutrients are charged with electricity in fluids and are responsible for transmitting signals in nerves and contracting muscles. They play a vital role in the proper functioning of the human body and are indispensable for the heart's beating.

Electrolytes are lost during fluid loss, especially through sweating. As water does not contain electrolytes, it is crucial to consume foods containing these nutrients to replace the lost electrolytes. Drinking fluids such as 100% orange juice that contain water and electrolytes can support hydration.


What Electrolytes does Orange Juice Have?

While some electrolytes like potassium and magnesium in orange juice are natural, fortified juices contain added electrolytes like calcium.


Potassium is the primary electrolyte present in all cells, which aids in regulating the body's fluid balance by collaborating with sodium, the primary electrolyte found in the bloodstream and outside of cells. 

The majority of people consume excessive sodium and not enough potassium. Orange juice is a beneficial source of potassium, with an 8-ounce glass of 100% orange juice providing 10% of the suggested daily value for potassium, which is comparable to a large banana.


Magnesium plays a crucial role in several significant bodily functions such as muscle contraction, cardiac excitability, and blood pressure regulation. It is the fourth most abundant mineral present in our body. 

Consumption of orange juice can aid in fulfilling the daily requirement of magnesium as an 8-ounce glass of it contains 6% of the recommended Daily Value for magnesium.


Fortified orange juice can be good source of calcium, as it contains around 30% of the recommended Daily Value. Calcium is crucial for various functions in our body, including muscle contraction, nerve transmission, and cardiovascular system regulation. 

This means that it plays an important role in keeping our body functioning properly. Additionally, the amount of calcium in fortified orange juice is comparable to that of an equal serving of milk. However, the sugar content of fortified and pasteurized juice can be high, and it may be better to get your calcium from other sources.

What Orange Juice is Best for Hydration?

Store bought orange juice will never be as pure or taste as fresh as cold pressed OJ. Oranges only grow in certain seasons, so orange juice providers had to find a way to store orange juice for longer periods of time, so they developed a process called “deaeration.” 

This involves picking and squeezing the oranges, heating the juice to eliminate bacteria, and storing it in large tanks with no oxygen. This process allows the juice to last for up to a year, but it also causes it to lose its taste and some nutritional value. To restore the flavor, formulas similar to those used by fragrance companies to create perfumes are added to restore the typical orange juice flavor.

In general, it's better for you to procure fresh cold-pressed orange juice, from both a taste and nutritional perspective. You're consuming the juice close to it's harvest date, therefore many of the nutrients are still in tact. With no heat processing, you don't lose all those critical nutrients.

Bottom Line

In conclusion, orange juice is an excellent source of electrolytes, and can be an important part of a healthy diet. It is packed with essential minerals, vitamins and antioxidants that help to maintain hydration and electrolyte balance, while also providing essential nutrition. 

Cold-pressed juice is a great way to enjoy the benefits of electrolytes while avoiding added sugars and other additives. As such, cold-pressed orange juice is a great choice for those looking to increase their intake of electrolytes without consuming unwanted additives and sugar.
