Upgrade Your Endurance Fuel With Proxima C


Does your endurance fuel need an upgrade? Proxima C Endurance Fuel by Ultraverse Supplements is a no-expense-spared fuel that can likely give you the boost you need to take your endurance performance to another level. Whether you struggle with chronic stomach issues during long events or want to improve your performance, Proxima C has you covered.  

If any of the following apply to you, consider replacing your current endurance fuel with Proxima C and feel the difference for yourself.

You can’t take in the recommended amount of calories/per hour for your event.

It is well known that the longer your endurance event, the more calories/hour you should be taking in. 

For example, in a 100-mile ultramarathon, one should aim for a minimum of 300 calories/hour, and 350-400 is even better. The vast majority of these calories should come from carbs. A well-formulated endurance fuel is the simplest and, for most people, the most effective way to do this. Food digests much slower than carbohydrate drinks, which can leave you bloated and wreak havoc on your G.I. system.  

How Proxima C Endurance Fuel can help.

Proxima C was formulated to be consumed in amounts that would likely cause issues when using the BIG brands. Cluster Dextrin (the primary carb in Proxima) has a super-fast gastric emptying time, allowing you to take in more carbs more often. Proxima C will help you elevate your caloric intake above traditional fuels. 

You experience Gastrointestinal distress during long endurance sessions.

Gastrointestinal distress is ubiquitous during long endurance events.

G.I. issues are the #1 reason for DNFs during ultramarathons and are all too common come race day. Of course, much of this can be prevented by adequately training your gut. That said, most endurance fuels were not formulated to prevent G.I. issues over super-long periods of endurance exercise – like ultras.

Proxima C’s carbohydrate blend was formulated to not only help you perform at your very best but also to prevent G.I. issues like nausea, bloating, diarrhea, and indigestion better than any other endurance fuel on the market.

Best carbohydrates for ultra-runners

Proxima C excels in this area because of its primary carbohydrate – Cluster Dextrin. Cluster Dextrin leads to less G.I. distress than any of the traditionally used endurance carbohydrates like sucrose, maltodextrin, fructose, and dextrose.

In fact, Cluster Dextrin has been shown to cause as few G.I. disturbances as drinking water alone. It’s no wonder Cluster Dextrin won the Ringier Technology Innovation Award in 2020 for its ability to enhance stamina, reduce intestinal discomfort, decrease perceived exertion, and suppress inflammatory stress in athletes.

Ultraverse Supplements didn’t stop there in the pursuit to eliminate G.I. issues. Each electrolyte in Proxima C was selected based on gut tolerability, absorption, and overall effectiveness, not by price.

You develop “taste fatigue” during prolonged usage of your current endurance fuel.

The likelihood of taste fatigue increases the longer endurance exercise persists and is typically due to excessive sweetness.

How Proxima C Endurance fuel can help.

Proxima C was developed for super-long efforts. Proxima C’s flavor profile was formulated with these things in mind. Proxima C has a light flavor profile and is significantly less sweet than conventional endurance fuels, preventing palate fatigue.  

You experience significant energy swings during long efforts or races.

Fueling entirely with simple carbohydrates like sucrose and/or dextrose will lead to significant energy swings throughout a very long event. This is due to the high glycemic impact of these particular carbs.

How Proxima C Endurance fuel can help.

Proxima C solves this issue by utilizing various carbohydrates, with most calories coming from lower glycemic carbs like Cluster Dextrin and Palatinose.

That’s not to say higher glycemic carbs like sucrose and dextrose don’t have their place in an endurance fuel (we use those, too), but using them exclusively isn’t optimal in long endurance efforts. 

You’re willing to pay a little extra for a performance boost.

When companies use carbs like sucrose, dextrose, and maltodextrin exclusively, they can undoubtedly create a more affordable final product. To again use Cluster Dextrin as an example, the price of Cluster Dextrin is about 5x the price of any of the previously mentioned carbohydrates. 

But in this case, you get what you pay for, and while expensive, carbs like Cluster Dextrin and Palatinose have significant benefits over their cheaper competition.

How Proxima C Endurance Fuel can help.

Proxima C only contains ingredients believed to be the best for endurance athletes based on various factors. It was formulated by ultra-runners and nutrition experts utilizing those ingredients in ratios believed to be optimal for super-long endurance efforts.

From the carbohydrate profile down each individual electrolyte, Proxima C was formulated to do as much as an endurance fuel can possibly do for optimal performance, with no consideration for formula price. 

This can understandably lead to a price tag beyond what some are willing to spend. However, it also results in the best extended-duration endurance fuel on the planet.
