Arginine and its derivative, AAKG (arginine alpha-ketoglutarate), are popular ingredients in pre-workout supplements, known for their properties to promote nitric oxide production and improve blood flow to muscles. As a result, arginine and AAKG are often used to increase muscle “pumps” and improve physical performance, making them extremely popular among athletes and bodybuilders.
How do arginine and AAKG work?
Arginine is an amino acid that plays a key role in the synthesis of nitric oxide—a compound that dilates blood vessels and improves blood flow. Improved blood supply to the muscles leads to an increased supply of oxygen and nutrients, which can contribute to increased physical performance and a more intense muscle “pump” during training. AAKG, a combination of arginine and alpha-ketoglutarate, further supports energy metabolism, which can contribute to even better training results.
Why use arginine and AAKG?
The use of arginine and AAKG has numerous benefits for strength trainers and athletes. Supplementing with these compounds can contribute to increased physical performance, improved circulation, and intensified muscle “pump,” which translates into better training results. In addition, arginine and AAKG promote muscle recovery after training, which is essential for building muscle mass and preventing overexertion. Regular use of arginine and AAKG can also support cardiovascular health.
How to use arginine and AAKG?
Arginine and AAKG are best taken before training to maximize their properties of supporting nitric oxide production and improving blood flow. The recommended dose is usually 3-6 grams of arginine or AAKG, consumed about 30 minutes before training. These supplements can be taken in powder or capsule form, dissolved in water. Regular use of arginine and AAKG, combined with a proper diet and training, can provide significant benefits in terms of increasing physical performance and improving overall physical condition.
