SKU: X130 Category:


L-Arginine is an amino acid that helps make proteins and is necessary for the production of nitric oxide. Nitric Oxide is a signaling molecule that is required for a variety of bodily processes and functions including blood flow regulation, mitochondrial function(energy) and cellular communication.

To achieve maximum muscular growth, your working muscle needs adequate blood flow to improve muscular
efficiency of ATP production in the mitochondria (reducing the oxygen cost of exercise).

The removal of ammonia and other metabolites through better blood flow allows athletes to recover more quickly
and may result in better growth stimulus and adaptive growth response to micro-tears.

Recommended dose is 2 capsules 30-60 minutes before exercise.

Medical Information

Nitric Oxide booster is a highly effective supplement for athletes. XENOLABS combined a pure form of natural supplements that optimize the nitric oxide level in the body. These ingredients comply with the USDA-certified organic ingredient criteria and do not involve any synthetic chemicals. It is essential to mention that the premium quality ingredients synergize the health outcomes of each other. Moreover, these ingredients were processed in a well-certified facility using GMP guidelines. Plus, a third-party lab dually tested the final product for safety and efficacy. The final formulation does not contain any soy, preservative, and gluten for maximum acceptability and palatability.

Benefits of Nitric Oxide Booster 

  • Support Blood Circulation
  • Boosts Energy production
  • Increase Nitric Oxide level
  • Relieve Muscle Soreness
  • Strengthen the Immune system

Role of Ingredients:

The nitric oxide booster contains four main ingredients, including Calcium, L-Arginine, L- Arginine Alpha-Ketoglutarate, L- Citrulline, and L- Arginine ketoisocaproate that naturally increases the concentration of nitric oxide in the body. [1, 2, 4] Increased nitric oxide level widens the blood vessels, improves blood circulation to the muscles, and supports optimum muscle growth. Moreover, proper concentration of nitric oxide potentiates physical performance and helps nutrient absorption and distribution to the needy parts of the body. [4, 6]Besides, the Alpha-Ketoglutarate speeds up wound healing, modulates the immune response, and helps bone and muscle development. L-Citrulline and L-Arginine also help muscle soreness, relieve fatigue and increase energy production that boosts physical performance. [2, 3, 5] Thus, the nitric oxide booster formulation supports the anabolic process, increases muscle endurance, and provides a stronger pump.
