Nexus Sports Nutrition NAC delivers pure, high-grade N-Acetyl Cysteine designed to boost your body's natural antioxidant defences, enhance cellular detoxification, and support optimal immune function. Crafted for athletes, hard-training gym-goers, and health-conscious Australiaers, this essential amino acid derivative helps combat exercise-induced oxidative stress, keeping your body performing and recovering at its absolute peak.

Key Benefits & Features

• Master Antioxidant Precursor: Directly fuels the production of glutathione, the body's most powerful natural antioxidant.

• Cellular Detoxification Support: Promotes healthy liver function and assists the body in processing metabolic waste and environmental toxins.

• Immune & Respiratory Defence: Helps maintain healthy bronchial function and strengthens immune system resilience against intense physical stress.

• Reduces Muscle Fatigue: Combats cellular oxidative damage caused by heavy lifting and endurance training to accelerate recovery.

• 100% Pure & Unflavoured: Clean, filler-free powder that mixes effortlessly into your favourite daily shakes or sports supplements.

How It Works

N-Acetyl Cysteine (NAC) is a stable, bioavailable form of the non-essential amino acid L-cysteine. In the body, NAC acts as the primary rate-limiting building block for the synthesis of glutathione—an intracellular antioxidant that neutralises harmful free radicals and protects cellular membranes from oxidative damage.

During strenuous resistance workouts and high-volume training blocks, oxidative stress levels rise sharply, accelerating muscular fatigue and slowing down recovery. By replenishing intracellular glutathione stores, Nexus NAC shields muscle tissue, supports vital liver detoxification pathways, and promotes clear respiratory airflow, ensuring whole-body recovery and sustained training longevity.

Recommended Use

• Serving Size: Mix 1 scoop (approx. 1g) into 150–250ml of cold water, juice, or your preferred daily supplement shake.

• Timing: Consume 1 serving daily, preferably with a carbohydrate-containing meal to optimise amino acid absorption.

• Usage Tip: Because pure NAC powder has a naturally sour, acidic taste profile, it is best mixed into flavoured beverages or fruit juices.
