Sport Armour CITRULLINE

Sport Armour Citrulline is a clean, focused single-ingredient-plus formula delivering Citrulline Malate 2:1 and Taurine to support nitric oxide production, blood flow, endurance, and pump. Each scoop provides 2,500mg of Citrulline Malate and 100mg of Taurine in a 2.6g serving.

Citrulline Malate 2:1 is a compound combining L-Citrulline and malic acid in a 2-to-1 ratio. It is one of the most widely researched pre-workout ingredients, associated with enhanced nitric oxide production, improved blood flow, better muscle pumps, and delayed onset of fatigue.

Sport Armour Citrulline is designed to support better pumps, increased vascularity, improved blood flow, reduced fatigue, and enhanced stamina during training. The addition of Taurine supports electrolyte balance, hydration, and neuromuscular performance.

Taurine (100mg per serving) is a conditionally essential amino acid included to support electrolyte balance, endurance, neuromuscular performance, cellular hydration, and oxidative stress reduction post-exercise.

Yes. Sport Armour Citrulline contains no caffeine or stimulants. It is a clean pump and performance formula suitable for any time of day, including evening sessions, or for stacking with a stimulant pre-workout.

Mix one scoop (2.6g) with water and consume before training. Its light serving size and clean formula make it easy to incorporate as a standalone pump ingredient or as part of a broader pre-workout stack.

Yes. As a stimulant-free, single-focus pump formula, Sport Armour Citrulline is well-suited for stacking with stimulant-based pre-workouts, creatine products, or other pump formulas to build a customised pre-training stack.

Sport Armour Citrulline is ideal for athletes seeking better pumps and blood flow, pre-workout users wanting to boost nitric oxide naturally without stimulants, and those who prefer clean, simple, single-ingredient-focused supplementation.

L-Citrulline is the pure amino acid, while Citrulline Malate bonds L-Citrulline with malic acid. The malate component may contribute additional energy support via the Krebs cycle, and the 2:1 form is the most common ratio used in sports nutrition research.
