SISU NAC 600mg Details

SISU NAC 600mg provides a high-potency 600 mg of N-acetyl-L-cysteine in each vegetable capsule. It helps relieve symptoms of chronic bronchitis, and helps reduce symptoms of respiratory infection and support the immune system for those over 65 or suffering from chronic degenerative diseases. NAC helps replenish glutathione, the body's "master antioxidant". The therapeutic dose is just 1 to 2 capsules a day with a protein-containing meal. 120 vegetable capsules. Non-GMO, gluten-free and dairy-free. Its natural sulfur content gives NAC its distinctive odour. Made by SISU.

Who SISU NAC 600mg Is For

  • Adults looking to help relieve symptoms of chronic bronchitis
  • Adults over 65, or living with a chronic degenerative disease, who want to help reduce symptoms of respiratory infection and support the immune system
  • Anyone wanting to help replenish glutathione, the body's master antioxidant
  • People who want extra respiratory support during cold and flu season
  • Those concerned about second-hand cigarette smoke — SISU notes NAC helps protect against it

Who this product is NOT for:

  • People who are bothered by sulfur odours — NAC naturally smells of sulfur
  • Pregnant or breastfeeding women, unless a health care practitioner advises it
  • Anyone looking for a fast cough suppressant — NAC is an antioxidant and mucolytic, not a cough medicine

Vitamart's Take

NAC is one of the best-studied respiratory and antioxidant supplements, and SISU's version keeps it clean: 600 mg in a vegetable capsule with only two non-medicinal ingredients. We like that SISU spells out two clear uses on the label — chronic bronchitis, and respiratory and immune support for people over 65 or with chronic degenerative conditions. A 120-capsule bottle lasts two to four months depending on your dose. The sulfur smell is normal and a sign of the real thing.

How SISU NAC 600mg Compares

NAC vs. glutathione supplements

Glutathione supplements give glutathione directly. NAC supplies cysteine, which the body uses to build its own glutathione, and has well-defined respiratory uses.

NAC vs. SISU Cold and Flu Rescue

SISU Cold and Flu Rescue combines Ester-C, andrographis, NAC and echinacea for short-term use during a cold. NAC 600mg is single-ingredient and higher dose for ongoing respiratory support.

NAC vs. vitamin C

Both are antioxidants that support the immune system. Vitamin C is a general immune nutrient, while NAC is focused on glutathione and the respiratory tract. Many people take both.

What Is NAC (N-Acetyl-L-Cysteine)?

  • NAC (N-acetyl-L-cysteine) is a form of the amino acid cysteine
  • NAC helps increase levels of glutathione, considered the "master antioxidant" in the body and an important part of your cold defence system
  • Boosted by NAC, glutathione helps protect the lungs against respiratory illness
  • NAC decreases the frequency of flare-ups and symptoms of chronic bronchitis
  • SISU notes research showing that NAC significantly decreases the severity of cold and flu symptoms

How To Use

  • Chronic bronchitis: take 1–2 capsules daily, or as directed by a health care practitioner
  • Respiratory infection and immune support (adults over 65 or with chronic degenerative diseases): take 2 capsules daily, or as directed by a health care practitioner
  • Take with a meal that contains protein
  • Close the bottle tightly after use and store in a cool, dry place
  • Keep out of reach of children
