We know what you’re probably thinking. Between the name and the packaging, Ener-C seems curiously similar to another mass-market powder-based electrolyte brand. A review of the company’s website gives us some insights into this. It turns out that Ener-C was founded by a group of people who formerly worked at Emergen-C and wanted to start their own brand after Emergen-C was acquired by a large pharmaceuticals company. Their motivation was to use their collective knowledge to create something better. They developed Ener-C with the intent of providing consumers a clean and healthy product made from planet-friendly ingredients. 

The HydrationReview team found Ener-C to be a good-tasting electrolyte supplement that was moderately effective when used before, during and after physical activities. Reviewers noted moderate to positive results when taking Ener-C in less strenuous situations such as during a day at the office or while road tripping. 

With only 1g of sugar and 125mg of sodium, Ener-C is objectively a lighter electrolyte supplement that can support moderate physical recovery or basic daily hydration practices. If you’re someone who likes to stay active but isn’t necessarily pouring sweat on the trails, Ener-C could be a good match for you. 

For readers who came here looking for a comparison to the other “C” electrolyte product, here’s our take: We like that Ener-C has a streamlined list of ingredients and found the drink goes down a lot easier. With Ener-C you don’t get as much “fizz” and the drink is a lot lighter and tastes better (though opinions may vary).

Ener-C is the perfect electrolyte to bring along during a hike. We found it tasted great with any amount of water ranging from 16oz to 24oz.


The Effectiveness score indicates the consumption of Ener-C resulted in a moderate effect when tested by our team. There weren’t any reports of significantly improved physical performance, though reviewers did note they felt hydrated and were able to get through the workouts they had planned without any trouble. One reviewer who typically chooses a medium distance run as his testing grounds for electrolytes didn’t report the same increases in physical output as he had with other electrolyte brands, though overall, he enjoyed testing the product.

“I had a solid run but didn’t notice any sort of improvement to my physical output. Taking it didn’t hurt though. I actually found the drink to be refreshing and it helped me get down more water before I hit the pavement.”


In other situations, reviewers tried Ener-C in more sedentary scenarios and noted they felt slight improvements to their physical well-being. Taking Ener-C helped restore hydration which in turn had some positive effects such as improved energy levels and increased alertness. One reviewer who spends a lot of time at the beach during the summer had this to say:

“I spend a good amount of my summer at the beach and even though I’m usually not in direct sunlight, I feel the need to keep hydrating…I liked Ener-C overall…I felt refreshed within 15 or so minutes after drinking it during the days I was testing it out.”

Here’s our final takeaway on effectiveness: You probably won’t feel a huge boost in energy after taking Ener-C, however, it will help you sustain basic hydration levels. Though this product is marketed as a “sport” formula, you’ll probably notice more of an effect using it as a supplement for daily hydration outside of physical activities.


Ener-C Sport only comes in the “mixed berry” flavor. When mixed with the recommended 16oz of water, it made for a good tasting pre-anything drink. The flavor isn’t overpowering and for some reviewers, it made it easier for them to put back water and stay hydrated. 

Compared to the other “C” brand, both the color and the taste of Ener-C is much lighter. For team members who had tried both brands, the choice for best flavor was unanimous. Go with Ener-C.

Mixed Berry is the only flavor available in the “Sport” line. If you’re looking for other flavors you can try “Ener-C” (non-sport) which comes in other flavors including Orange, Peach Mango, Lemon Lime and Raspberry.


In the ingredients list for Ener-C, you’ll find all of your core electrolytes including magnesium, sodium, chloride and potassium. Combined with an added 1g of sugar (which is derived from natural flavorings like raspberry juice powder and coconut water powder), a serving of Ener-C provides your body with the key ingredients for proper hydration. 

Ener-C is also listed with 1g of carbohydrates which makes this a great choice for readers who are on the keto diet.
