Key Features

  • Health Benefits - NAC (N-Acetyl-L-Cysteine) is a powerful antioxidant precursor to glutathione, supporting detoxification, cellular defense, and overall wellness. It can help maintain lung function and respiratory health. Selenium is a natural micronutrient that may play a vital role in many essential body functions. Selenium contributes to normal spermatogenesis, maintenance of hair, maintenance of nail, function of the immune system, thyroid function, and protection of cells from oxidative stress.
  • Maximum Strength - Each capsule contains 600 mg of N-Acetyl-L-Cysteine (NAC) and 100ug of L-Selenomethionine, an organic form of selenium, a perfect combination designed to enhance the body's natural production of glutathione and support detoxification pathways. This formula is ideal for addressing environmental toxin exposure and other health conditions associated with oxidative stress.

Frequently Asked Questions

NAC helps boost the body’s glutathione levels, a key antioxidant for detoxification. Selenium (as selenomethionine) supports immune function, thyroid health, and protects cells from oxidative stress. Together they enhance each other’s protective effects.

It’s especially useful for those exposed to environmental toxins (pollution, smoke, chemicals), those under oxidative stress (e.g. high training loads, poor diet), or anyone aiming to support immune system resilience. It may help support respiratory health and reduce damage from free radicals.

Some users report feeling more resilient (less fatigue, improved breathing comfort or immune responses) within 1-2 weeks; more noticeable antioxidant support or respiratory improvements tend to come with consistent use over 4-6 weeks.

Take 1 capsule daily with food and water. Pairing with a diet rich in antioxidants (fruits, vegetables), staying hydrated, and avoiding exposure to known oxidants (like smoke) will help this formula work better.

This formula is most valuable for people facing moderate oxidative stress who want a strong, combined antioxidant & immune support. If symptoms persist or stress is very high (e.g. illness, pollution, heavy workload), some users later combine with other respiratory or immune-support products or increase supportive lifestyle changes.
