Intra-Workout

What are intra-workout supplements?

Intra-workout supplements are products formulated to be taken during a training session, with the aim of maintaining energy levels, reducing muscle fatigue and supporting hydration throughout physical exertion. Unlike pre-workouts, which prepare the body for exercise, and post-workouts, dedicated to recovery, intra-workout supplements act in real time to extend performance and limit muscle breakdown during long or high-intensity sessions.

What are the main ingredients and what do they do?

Intra-workout supplements are typically available as powders to dissolve in water during training, combining active compounds with complementary roles:

• BCAAs (branched-chain amino acids – leucine, isoleucine, valine): essential amino acids used to support the reduction of muscle breakdown during prolonged exercise.
• EAAs (essential amino acids): a more complete amino acid profile compared to BCAAs alone, increasingly used in modern intra-workout formulas.
• Fast-absorbing carbohydrates (maltodextrins, cyclic dextrins, Vitargo®): provide rapid energy to muscles during exercise and support the maintenance of glycogen stores.
• Electrolytes (sodium, potassium, magnesium): sodium contributes to normal muscle function and the maintenance of fluid balance; essential for preventing cramps and compensating for sweat losses.
• Citrulline and L-glutamine: supporting ingredients for microcirculation and muscular endurance during intense sessions.
• B vitamins: contribute to normal energy metabolism and the reduction of tiredness and fatigue.

When and how should you take them?

Intra-workout supplements are taken directly during training, sipping the solution throughout the session. They are particularly recommended for workouts lasting over 60–75 minutes, for endurance disciplines (running, cycling, swimming, CrossFit) or for those training in intense heat with heavy sweating. Prepare the dose by dissolving the powder in 400–600 ml of water. Always follow the directions on the label. Remember: food supplements are not intended as a substitute for a varied and balanced diet and a healthy lifestyle.
