Life Changing

My functional nutritionist recommended this supplement for me, as he takes it himself. I noticed almost an immediate difference in my mood and energy levels. I consistently hear the benefits of NAC across health professionals with new substantial evidence arising.† ~Emmy R.

Your cells are constantly under attack. Free radicals and oxidative stress from environmental toxins can significantly burden your liver.

Even normal processes like hormone metabolism contribute to toxicity. In our modern world, maintaining healthy antioxidant status and detoxification pathways is essential for your health.†

NAC by Seeking Health provides 500 mg of N-acetyl-L-cysteine per vegan capsule.

NAC (N-acetylcysteine) is an important sulfur-containing amino acid. By facilitating glutathione production, NAC supports healthy detoxification and antioxidant function in virtually every cell of the human body. NAC also has the unique ability to support the normal break up of mucus in the lungs, making it popular for lung and immune health protocols.†

NAC acts directly and indirectly as an antioxidant. Its unique chemical structure contains an outer sulfur group. This allows NAC to act as an antioxidant, particularly for NO2 and hydroxyl radicals.†

NAC is also a bioavailable source of cysteine. This rate-limiting amino acid is needed to build glutathione, which acts as your body’s master antioxidant.†

Your liver requires glutathione for multiple functions. Glutathione can readily donate electrons to act as a potent antioxidant. It also binds toxins, drugs, and hormones so your body can excrete them. The World Health Organization (WHO) recognizes NAC as a substance that supports liver cell health, especially with exposure to compounds known to cause liver damage.†

It is well known that cells (particularly immune, lung, reproductive, and brain cells) function optimally when glutathione levels are in peak range. However, glutathione levels decline naturally with age. They are depleted even faster when the body does not have enough cysteine.†

NAC by Seeking Health supports healthy glutathione levels by providing a bioavailable source of cysteine.†

Use of NAC can also support lung and respiratory health. It has been well established that NAC supports the normal thinning of lung mucus. It does this by interfering with the disulfide protein bonds found in mucus. This allows mucus to be more easily expelled from the lungs.†

NAC supports healthy:†

  • Lung tissue
  • Respiratory function
  • Glutathione production
  • Antioxidant status
  • Immune health
  • Hormone balance
  • Liver health
  • Detoxification
  • Oxidative damage defenses
  • Brain & Nerve health
  • Reproduction & Fertility
  • Healthy aging processes

In most supplement forms found on the market, glutathione may not be as well-absorbed or utilized as NAC. Supplementing with high-quality liposomal glutathione may not be an option for everyone due to the increased cost and strong sulfur taste. NAC is a cost-efficient way to support natural glutathione and antioxidant activity in your body.†

NAC by Seeking Health supports healthy glutathione production, detoxification, respiratory health, and much more. Always keep a bottle in your immune toolbox–this popular product tends to fly off the shelves!†

    NAC the best I used

    I went through not being able to tolerate other NACs until I bought Seeking Health NAC and I feel better taking the NAC then before I started taking. So far an excellent product.

    Not for everyone.

    I wanted to leave another review for this product. I have tried it more than once and gave some to other family members to try too. It didn't agree with them either. I am a celiac and homozygous for A1298c. I've read the other reviews and my reaction was similar to others that have this methylation snp too. For me it seems to increase increase glutamate and leaves me feeling anxious and wired. Product may work well for some, but it is not for everyone.
