Runivore Ucan Edge review

Runivore Tom and I are rarely in complete agreement regarding race fueling. We like to run different races, and he likes most energy gel flavors, while I believe there are no tasty gels, only palatable ones.

Well…Ucan Edge Energy Gels are something we can both get behind. Read his Ucan Edge energy gel review here.



With the popularity of the keto diet and fat as fuel concepts and more research on the adverse effects of sugar, Ucan has garnered interest among health-conscious athletes. Professional marathoners Sara Hall and Meb Keflezighi and distance runner Joe Klecker are some world-class athletes listed as Ucan users.

I fueled a 30km run at easy-to-moderate effort with two Ucan Edge energy gels. Below is my experience and what I’ve learned researching the brand.

What makes Ucan different? Livesteady, the secret sauce

“Ucan is here to help you finish your workout and day strong while fitting into your keto diet and lifestyle…powered by Livesteady – a unique, low glycemic, complex ingredient that delivers steady, long-lasting energy nutrition with no spikes and no crash,” the company claims.

The main ingredient of Ucan Edge is Livesteady, a corn-based complex carbohydrate. According to the company, in 2008, European scientists discovered a new way to process starches, which yielded a slow-digesting carbohydrate.

Unlike conventional sports drink mixes and energy gels made with simple sugars, which elevate blood sugar, here are several research-backed benefits listed on Ucan’s website.

  1. Optimized performance with steady energy without the spike and crash of sugar- and maltodextrin-based products.
  2. Sustained energy with time-released delivery of glucose, keeping you above baseline longer.
  3. Enhanced fat burn.
  4. Speedier recovery as your body can use protein to repair and restore your muscles rather than for energy since blood sugar is stable.
  5. No gastric distress because Livesteady is a large molecule that passes through the stomach quickly and is digested slowly in the intestines.

What are the ingredients of Ucan Edge?

Orange Flavor UCAN Edge Energy Gel Ingredients and Nutrition Info

I tested the Orange flavor. Ucan Edge also comes in Pineapple and Strawberry Banana.

Erythritol is listed second on the ingredient list behind Livesteady. Erythritol is a sugar alcohol often used as a low-calorie sweetener. It is especially low in calories, at 0.24 calories per gram, compared with table sugar, which contains 4 calories per gram. 

Erythritol also doesn’t raise blood sugar because humans don’t have the enzymes to process it. The sugar alcohol is absorbed into the bloodstream and then excreted unchanged through urine.


Nutritional facts

Ucan Edge is a 53 g gel with 70 calories of energy. The key energy source is 19 g of carbohydrates, specifically LIVSTEADY corn starch. 

The energy gel has zero fats and proteins, 55 mg of sodium, and provides 100% of recommended daily vitamin C intake.


The package of Ucan Edge is big, about 11 cm in length. If you choose it as your race fuel, ensure the gels fit in your short pockets and race belts.

Due to the length of the sachet and the narrower neck where the rip is located, it was difficult to completely suck out the content. This could be an issue when running at a harder effort and maintaining a steady breathing rhythm is imperative.

Taste and consistency

Although I tested the orange-flavored version, the taste was an indistinct fruitiness. It wasn’t bad. 

Texture-wise, it’s on the watery side but has a subtle gritty texture due to the use of Livesteady corn starch as an ingredient. It’s different but not unpleasant.

How did Ucan Edge energy gel perform?

I took two Ucan Edge Orange energy gels on a 30km run at easy-to-moderate efforts (the last 4km at marathon pace). The entire workout was 2 hours and 48 minutes. 

I began the run on an empty stomach and took the gels at the 1- and 2-hour marks.

In 2017-18, I experimented with a low-carb diet while training for my first 100-miler. I performed many fasted long runs and mostly avoided added sugar and starchy foods. Therefore, the nutritional concepts the company has incorporated into its products aren’t foreign to me.

Here are a few takeaways:

  1. My energy level was maintained at an optimal level. I’m currently running high mileage and expected to feel cumulative fatigue. Instead, I felt strong.
  2. The starchy texture was certainly different. The first gel consumed was a bit of a surprise, but overall, the taste and texture were tolerable.
  3. However, sucking out the gel took effort. To get to the gel at the bottom of the sachet, I had to use two hands, toothpaste-squeezing style.
  4. The energy gel is sugar-free, gluten-free, keto-friendly, vegan-friendly, and non-GMO. On paper, Ucan Edge is the healthiest energy gel I’ve tested. 


Ucan Edge is a big gel at 53 g but provides only 70 calories and 19 g of carbohydrates. Both the caloric and carbohydrate content are below average for such a large pack (a typical gel is about 30 g and provides around 100 calories and 20-25 g of carbohydrates).

However, the orange-flavored Ucan Edge sustained me on a 30km run at easy-to-moderate efforts and on tired legs. I was expecting to really feel the cumulative fatigue of the training block, but my energy level was good throughout.

The flavor is palatable, with an indistinct fruitiness and a subtle starchy texture.

If your digestive system is sensitive to sugar spikes, or you are practicing a keto diet or have diabetic conditions, we strongly recommend you look into Ucan products. 

This energy gel is Runivore approved.
