What Are Electrolytes?

Electrolytes are essential for basic life functions and maintenance of electrical neutrality in cells,  generation, and conduction of action potentials in the nerves and muscles.

These electrolytes can have imbalance that disrupts the normal bodily functions and can even lead to even life-threatening complications (1). 

Gatorade zero also contains gum arabic, a natural thickener. To give the beverage a body to the palate, gum arabic is added, a natural plant polysaccharide. 

Non-caloric sweeteners added are Acesulfame Potassium and Sucralose. Both of these are declared by the US FDA as safe for use in humans.

Package Flavors and Sizes

Why Do People Drink Gatorade Zero?

Gatorade Zero boasts its electrolyte replenishment that cannot be supplemented by plain water. Most especially for individuals who are highly physically active. But how essential are electrolytes to the body? 

To facilitate important bodily functions, electrolytes are distributed through the fluid in the body and utilized as electrical energy, since these are charged ions (2).

These are important to control (3):

  • Water balance
  • Regulate blood pressure
  • Aids in muscle contraction – including the heart
  • Maintain correct body pH

Common electrolytes include calcium, magnesium, potassium, sodium and chloride. Gatorade Zero contains potassium and sodium. Concentrations vary with every electrolyte water available in the market. 

This contains no sugar and 2 grams of carbs. No sugar spike in Gatorade Zero, such that it contains alternative sweeteners: acesulfame potassium and sucralose which are known to have little to no effects on the blood sugar. 

When Should Gatorade Zero Be Consumed?

Anytime of the day, although this is great with any physical activity such that it helps replenish electrolytes that are lost. 

Generally after an hour of activity, exercising outdoors or a heavy sweater, sports drinks may be consumed (4). 

It can also be taken under the signs of dehydration such as, feeling dizzy, fatigued, headaches and rapid heartbeat. These are signals that the body is lacking fluid and electrolytes (5). 

Is Gatorade Zero Keto Friendly?

Gatorade zero contains very low calories, however it contains the artificial sweeteners acesulfame potassium and sucralose which strict-ketogenic dieters tend to avoid.

Because of this, Gatorade zero is okay for low-carb diet, and ‘dirty-keto’ but not for strict-keto, even though it’s sugar-free and might not kick you out of ketosis.

Where to Buy

Gatorade Zero can be bought on, Walmart and in Gatorade’s online store.


Gatorade Zero contains 5 grams of carbs per serving which is okay for low-carb dieters. However since it contains artificial sweetener, it would be avoided by strict-keto dieters.
