What Is a Dual Carbohydrate Energy Drink and Do You Need One?

You may have come across sports drinks described as containing dual carbohydrates. But what does this mean, and how is it relevant to your endurance training or events

Understanding Carbohydrates

During endurance exercise the body relies heavily on carbohydrates as a primary fuel source. Over time, these carbohydrate stores become depleted, leading to fatigue and decline in performance.

To maintain energy levels and support performance during prolonged exercise, it is recommended to consume carbohydrates. However, the type and amount of carbohydrate you take in can affect how well your body absorbs and uses this energy.

What Does “Dual Carbohydrate” Mean?

Sports nutrition products typically contain either one or two types of carbohydrates. The most common sources are:

• Glucose or Maltodextrin
• Fructose

When a product is referred to as containing "dual carbohydrates," it means it includes both glucose (or maltodextrin) and fructose. These two types of carbohydrates are absorbed by the body through different pathways, allowing for more efficient fuel uptake.

Here are some great dual source carbohydrate energy drinks:

• OTE Super Carbs Performance Energy Drink
• High5 Energy Drink
• Precision Fuel Carb Only Drink Mix
  
• STYRKR MIX90 Dual-Carb Drink
  

Why Is This Important for Endurance?

The body can absorb and use up to 60 grams of glucose or maltodextrin per hour. Consuming more than this from a single source may lead to gastrointestinal discomfort because the body cannot absorb the excess.

However, when fructose is added as a second carbohydrate source, the body can absorb more than this due to the use of separate absorption pathways. This means you can increase your carbohydrate intake without increasing the risk of gastrointestinal issues.

Carbohydrate Recommendations for Endurance Exercise

Should You Use a Dual Carbohydrate Drink?

If your training or competition lasts more than 2.5 hours, using a dual carbohydrate drink can help you:

• Maintain energy levels more effectively
• Delay fatigue
• Reduce the risk of gastrointestinal issues

For shorter sessions, single-source carbohydrate products may be sufficient. Choosing the right type of carbohydrate product based on exercise duration ensures more efficient fuelling and better overall performance.
