L-Citrulline is converted in the body to L-Arginine, which increases nitric oxide (NO) levels — a key molecule responsible for relaxing blood vessels and improving circulation. This leads to greater endurance, fuller muscle pumps, and better nutrient uptake. Unlike direct arginine supplements, L-Citrulline is absorbed more efficiently, offering superior and sustained nitric oxide support. Bull Nutrition L-Citrulline uses only pure, high-grade raw material to ensure maximum potency and clean performance.
Mix 1 scoop (3 g) with 6–8 oz of water or your pre-workout beverage and consume 20–30 minutes before training.
For advanced users, take 2 scoops (6 g) for enhanced pumps and endurance.

Supplements aren’t meant to replace real food — they complement your diet. Even with balanced eating, most people fall short on certain nutrients like Vitamin D, Omega-3s, or Magnesium. Supplements help fill those gaps, support performance, recovery, and overall wellness. The key is to use them strategically, not excessively.
Protein powder: Best taken within 30–60 minutes after a workout to support muscle recovery and growth. It can also be used as a meal replacement or snack during the day.
Pre-workout: Take it 20–30 minutes before training for maximum energy, focus, and endurance during your session.
Most high-quality supplements are safe when taken as directed. Always follow label dosages and consult your healthcare provider if you’re pregnant, nursing, or on medication. Choose trusted brands that are third-party tested and transparent about their ingredients — this ensures purity, potency, and safety.
