Interval running is one of the most effective training methods for improving endurance, burning fat, and increasing speed. By alternating between short bursts of high-intensity running and periods of lower-intensity recovery, you can push your body to new limits. However, to maximize your performance and recovery, the right supplementation is essential. Let’s explore the key active substances that can take your interval running to the next level.

1. Caffeine – Instant Energy Boost

Caffeine is a powerful stimulant that enhances alertness, reduces perceived effort, and improves endurance. It works by stimulating the central nervous system, allowing you to push through fatigue and maintain high intensity during intervals.

Dosage: 200-400 mg taken 30-60 minutes before training. Avoid exceeding 400 mg daily to prevent side effects like jitters and insomnia.

2. Beta-Alanine – Delaying Muscle Fatigue

Beta-alanine is an amino acid that increases carnosine levels in muscles, helping buffer acid build-up and reducing muscle fatigue during high-intensity efforts. This means you can sustain intense intervals for longer without burning out.

Dosage: 3-6 g daily, ideally split into smaller doses to minimize tingling sensations (paresthesia) that can occur.

3. Creatine – Explosive Power and Speed

Creatine monohydrate is one of the most researched and proven supplements for improving short bursts of power, making it ideal for interval running. It enhances ATP production, allowing you to generate more energy for sprints and recover faster between intervals.

Dosage: 3-5 g per day, taken at any time, with or without food.

4. BCAAs – Faster Recovery and Reduced Soreness

Branched-chain amino acids (BCAAs) support muscle repair and reduce exercise-induced muscle damage. They also help maintain muscle mass, preventing excessive breakdown during intense training sessions.

Dosage: 5-10 g before or after workouts to optimize muscle recovery.

---

5. L-Carnitine – Enhanced Fat Burning

L-Carnitine plays a key role in transporting fatty acids into the mitochondria for energy production. This results in improved fat metabolism and increased endurance, making it an excellent supplement for interval runners.

Dosage: 500-2000 mg per day, best taken before workouts for optimal effects.

---

6. Electrolytes – Hydration and Endurance

During interval training, sweating leads to significant electrolyte loss, which can cause cramps, fatigue, and dehydration. Replenishing sodium, potassium, magnesium, and calcium ensures optimal muscle function and endurance.

Dosage: Follow the product-specific recommendations, usually taken before, during, or after workouts.

Why Supplementation Matters for Interval Running

Supplementing with the right nutrients allows you to train harder, recover faster, and reach your running goals more efficiently. Whether you’re looking to boost energy, improve endurance, or speed up recovery, these active substances will give you a competitive edge.
