Rule 1 L-Glutamine delivers 100% pure, pharmaceutical-grade L-glutamine powder engineered to accelerate post-workout recovery, support immune function, and protect lean muscle tissue. Glutamine is the most abundant amino acid in the human body, but intense physical exercise can rapidly deplete your natural reserves. Unflavoured and completely free from fillers, sugars, or stimulants, Rule 1 L-Glutamine provides a clean, highly effective way to restore critical amino acid levels so you can bounce back faster from demanding training sessions.

Key Benefits & Features

• Accelerates Muscular Recovery: Helps replenish depleted amino acid stores following heavy weightlifting, high-intensity cardio, or endurance sessions.

• Supports Gut & Digestive Health: Serves as a primary fuel source for intestinal cells, promoting optimal gut lining integrity and nutrient absorption.

• Protects Lean Muscle Mass: Acts as a powerful anti-catabolic agent to minimise muscle tissue breakdown during periods of hard training or dieting.

• 100% Pure & Micronised: Specially processed for maximum solubility, dissolving effortlessly into liquid with zero gritty texture.

• Unflavoured & Versatile: Mixes seamlessly into your post-workout protein shake, BCAAs, or pre-workout without affecting flavour.

How It Works

During periods of heavy physical exertion, the body utilizes large quantities of glutamine, often exceeding its natural rate of synthesis. When cellular glutamine levels drop, recovery slows, muscle tissue breakdown increases, and immune function can be compromised.

Rule 1 L-Glutamine works by rapidly restoring plasma and intramuscular glutamine pools. This helps maintain positive nitrogen balance, essential for repairing micro-tears in muscle fibers. Additionally, the cells lining the gastrointestinal tract rely on glutamine as their main source of energy. By supporting healthy intestinal mucosal integrity, L-glutamine enhances overall digestive comfort and nutrient uptake, ensuring your body efficiently utilizes your wider athletic diet.

Recommended Use

Mix 1 level scoop (5g) with 200–300ml of water, fruit juice, or your daily post-workout protein shake in a Sprint Fit shaker. Consume once daily. On training days, take immediately following your workout. On non-training days, consume one serving first thing in the morning or right before sleep for continuous recovery support.
