Support your body’s natural defense and detox systems with Focal Nutrition’s N-Acetyl L-Cysteine (NAC)—a stable, highly bioavailable form of the amino acid L-cysteine. NAC is a powerful precursor to glutathione, one of the body’s most important antioxidants, helping to neutralize free radicals, support liver health, and maintain respiratory function.

Ideal for those looking to strengthen their cellular defenses, enhance recovery, and promote long-term wellness.

1. Powerful Antioxidant Support – Boosts glutathione production to fight oxidative stress

2. Promotes Respiratory Health – Helps thin mucus and supports clear airways

3. Supports Liver Detoxification – Aids in the removal of toxins and metabolic waste

4. Neuroprotective Properties – May support cognitive health and brain cell resilience

5. Stable & Fast Absorbing – Highly bioavailable and well-tolerated

Mix 1 serve (approx. 1g) with water or juice, daily, or as directed by your healthcare professional. Best taken on an empty stomach.
