Intra Carbs

Intra Carbs by Apex Formulas is a precision-formulated intra-workout carbohydrate powder delivering a 75:25 ratio of Highly Branched Cyclic Dextrin (HBCD) to Fructose.

Designed to fuel high-performance training and support sustained energy delivery, this unflavoured formula can be used on its own or mixed seamlessly with your favourite amino acid or hydration product.

With 60 servings per tub, each 20g dose provides a dual-pathway carbohydrate system that maximises energy availability and reduces fatigue. Ideal when stacked with Apex Muscle Juice, this product is a performance essential for endurance, strength, and recovery.

Highly Branched Cyclic Dextrin (15g per serving)

Also known as Cluster Dextrin®, this is a cutting-edge carbohydrate source developed for high-performance athletes. Its unique molecular structure allows for:

• Rapid gastric emptying without causing bloating or GI discomfort

• Sustained energy release during long or intense workouts

• Low osmolarity, meaning it doesn’t draw excess water into the gut (ideal during training)

• Efficient glucose delivery to working muscles to support strength, endurance, and performance

HBCD is widely used in elite-level intra-workout nutrition and is especially beneficial for those engaging in resistance training, bodybuilding, endurance sports, or high-volume gym sessions.

Fructose (5g per serving)

Fructose is a naturally occurring simple carbohydrate found in fruit. Unlike glucose-based carbs, fructose uses a separate absorption pathway in the body (via the GLUT5 transporter), which makes it the perfect pairing with HBCD.

Benefits include:

• Dual-carbohydrate absorption to increase total carb uptake without saturation

• Improved glycogen replenishment during prolonged exercise

• Balanced blood sugar response when consumed with glucose-based carbs

• Supports sustained energy without insulin spikes or crashes

Fructose is especially useful for intense gym sessions and endurance training especially in long sessions where your body's need for glucose uptake capacity is maxed out.

Why the 75/25 Carbohydrate Ratio Matters

The 75/25 split of HBCD to Fructose in Apex Intra Carbs is backed by real-world data and research. Glucose-based carbohydrates (like HBCD) are absorbed through the SGLT1 pathway, while fructose is absorbed through GLUT5. By combining both in the correct ratio, this formula:

• Maximises total carbohydrate absorption capacity

• Reduces gut discomfort or saturation

• Supports higher energy delivery rates per hour

• Delivers clean, stable energy for longer training sessions

This strategic carb ratio is ideal for intra-workout fueling, especially when combined with amino acids or Apex Muscle Juice, creating a powerful synergy for muscle preservation, hydration, and performance.
