Natural Factors N-Acetyl-L-Cysteine (NAC) is a free form amino acid and a vital part of the body’s antioxidant defence system. It is needed for the production of glutathione, a key antioxidant involved in many physiological processes, such as fighting oxidative stress, maintaining a healthy immune system, repairing tissues, cellular detoxification, and supporting overall health. NAC supplementation has been clinically shown to increase the body’s antioxidant capacity and help reduce the severity and frequency of influenza-like symptoms in adults over 65. NAC is also the most stable and readily absorbed form of cysteine.

As a free form amino acid, cysteine is one step closer to producing glutathione than when it is consumed as part of a complete protein from food. Oral supplementation with NAC also increases glutathione levels more effectively than supplementing with glutathione itself. This is because glutathione breaks down in the gastrointestinal tract whereas NAC does not. It passes into the bloodstream intact.

The 1200 mg per day (600 mg 2 times per day) is supported by clinical research. This is an ideal nutritional supplement for adults who would like to improve their immune system health. NAC is an effective option for anyone with high levels of oxidative stress or depleted glutathione stores.

• Scavenges free radicals and reduces oxidative stress
• Replenishes depleted glutathione stores
• Aids respiratory health
• Reduces the frequency of flu-like symptoms in adults over 65
