Nutritional Info

Drink to Prepare.
Drink to Refuel.
Drink to Recover.

Drink one specially designed 4.75 ounce bottle of XRCELTM Athlete Fuel 15 minutes before training or competing to give your body both an instant and extended release of muscle and brain fueling energy. Also use XRCELTM to refuel during lengthy training sessions or competitions to help you perform at your peak for a longer period of time.

  • RIGHT CARB

    Glucose - for immediate and sustained energy.

  • RIGHT LOCATION

    Specially formulated glucose micro-gels spend more time near the "glucose gateways" in the small intestine, improving the uptake of glucose into the body.

  • Right Time

    Patented micro-gels increase the release rate of glucose when body temperature levels rise during strenuous activity, providing you with more fuel in the heat of competition.

Ingredients to help you outperform, outthink and outlast your competition.

Supplemental Facts
XRCELTM Athlete Fuel is a great tasting, drinkable sports supplement made with specially formulated glucose, which is a simple carbohydrate (carb). Why glucose? Because glucose provides the most immediate source of fuel for your body and brain. What sets XRCELTM apart from other sports drinks and supplements is our patented glucose-loaded micro-gels. These pH and heat activated micro-gels are optimized to work with your body, to quickly and steadily release fuel as your body needs it, keeping you firing on all cylinders from start to finish. XRCELTM also includes essential electrolytes and minerals to give you the nutrients you need to maximize performance.

Glucose

Glucose is immediately available for energy.

The glucose in XRCELTM is a simple carb that can be converted to energy in one step. Fructose, galactose and other carbs, found in many sports drinks and supplements, require multiple steps to be converted to energy, making them a less efficient fuel source compared to glucose. [4-7]

XRCELTM delivers glucose to where your body needs it.

Along with an instant dose of muscle and brain fueling glucose, each 4.75 ounce bottle of XRCELTM delivers extended release micro-gels tuned to steadily release the right amount of additional glucose into your bloodstream. This extended release is controlled by the conditions in your digestive system, pH, and temperature. The micro-gels in XRCELTM are designed to optimize the release of glucose near the "glucose gateways" in the small intestine. XRCELTM also increases the glucose release rate as your core body temperature rises during strenuous activity.

Can too much glucose cause an energy crash?

Each 4.75 ounce bottle of XRCELTM delivers just the right amount of glucose to fuel your body, reducing the chance of elevating insulin levels and causing a crash in energy.

Carbohydrates

Fuel for your Body

What are Carbs?

Carbohydrates (carbs) are compounds made up of types of sugars, such as fructose, glucose, sucrose and galactose. Carbs come from the nutrients in the food you eat and are the most common fuel source used to power and replenish your muscles during physical activity. Carbs also have the most positive effect on exercise performance. [1-3] The carb your body looks for first when your muscles and brain need more energy is glucose, the main carbohydrate in XRCELTM.

Two types of carbs: [8-9]
Simple Carbs

Fruit
Sugar
Glucose
Sucrose
Fructose
Dextrose

Simple Carbs like glucose are broken down and absorbed quickly by your body, providing immediate fuel.

Complex Carbs

Vegetables
Whole Grains
Beans
Starch

Complex Carbs like starch are broken down slowly, taking longer to make the energy available.

How do carbs work?

Your body converts carbs, in the food you eat, into fuel for the body. All carbs are eventually converted to glucose, the main ingredient in XRCELTM, which is then rapidly converted to the energy that powers your muscles and brain. Any carbs not immediately used for fuel are converted to glycogen and stored in the muscles and liver for later use. Carbs provide both an immediate energy source and a way to store energy for later use. [3,15-20]

How can you use carbs to help maximize your body's potential?

Up to now, you had two fuel choices. Either immediate release carbs that upped the risk of an energy crash, or complex carbs that take longer to break down and may not be available when you need them. Ideally you want your body to burn carbs that provide immediate fuel for as long as possible, saving complex carbs as reserve fuel. XRCELTM Athlete Fuel helps you do just that by providing a combination of glucose that is available as immediate energy and an extended release dose of glucose your body will tap into later.

Extended Release

Fuel for when you need it

XRCELTM releases glucose when your body needs it.

Along with an instant dose of muscle and brain fueling glucose, each 4.75 ounce bottle of XRCELTM delivers extended release micro-gels tuned to steadily release the right amount of additional glucose into your bloodstream. This extended release is controlled by the conditions in your digestive system, pH, and temperature. The micro-gels in XRCELTM are designed to optimize the release of glucose near the "glucose gateways" in the small intestine. XRCELTM also increases the glucose release rate as your core body temperature rises during strenuous activity.

The extended release micro-gels in XRCELTM set free additional glucose when your body needs it, which could mean one less break to refuel during extended training or competitions. One less break can save you time and help you stay focused on outperforming your competition.

XRCELTM helps you push your body harder for longer.

Your body naturally stores enough energy for about two hours of exercise. To avoid hitting the wall, you need to refuel your body with carbs. XRCELTM is optimized to refuel your body with glucose – the most efficient carb - during athletic events. XRCELTM is optimized to help enhance athletic performance:

  • Instant release of glucose for immediate fuel
  • Glucose-loaded, extended release micro-gels provide an extended dose of fuel
  • Tuned to release glucose-loaded micro-gels when your body needs them
  • pH responsive formula puts fuel in the right location to optimize absorption, allowing rapid conversion of glucose to energy
  • XRCELTM helps the body use less glycogen and thus preserves energy reserves. And if reserves are depleted, XRCELTM helps restore them faster.
Simply put, XRCELTM lasts longer.
Distribution + Absorption:
More fuel where you need it

When you're pushing your body to the limit during physical activity, as much as 75% of blood flow is routed directly to your brain and muscles, reducing the amount of blood to your stomach and other parts of your body, including your digestive system. [12] This makes it harder for your body to digest food, so your brain begins searching for glucose, which it can immediately use as fuel. This is where the extended release micro gels in XRCELTM kick in. The micro-gels in XRCELTM wait next to the "glucose gateways" where they are efficiently absorbed into your bloodstream, taking the expressway to your brain and muscles. XRCELTM is an optimal way to supply your brain and muscles with the critical fuel needed to maintain your focus and intensity.

XRCELTM helps you stay focused and sharp.

Keeping your brain fed during intense exercise and competition is critical to maintaining focus and keeping your muscles moving. When the brain loses energy, it starts to shut down your muscles. [21-24] In the heat of intense activity, your brain seeks out the brain and muscle fueling glucose found in XRCELTM, which it can quickly convert to energy. Fueling up with XRCELTM gives you instant glucose, and more importantly, this new breed of carbohydrate supplement gives you an extended release of glucose as your body needs it. This means your brain and muscles are satisfied, letting you focus on the next mile, the spin of the ball, the trajectory of your shot and that split second between winning and losing. XRCELTM is an athlete fuel that helps with both the physical and mental part of performing at your peak.
