insightsAnalysis

This NOW brand product delivers 600 mg of N-Acetyl Cysteine per capsule, a compound that supports the body's natural antioxidant defenses by serving as a precursor to glutathione. It also includes the essential trace minerals Selenium (as L-Selenomethionine) and Molybdenum (as Sodium Molybdate).

This supplement is formulated to provide general support for cellular health, detoxification processes, and overall well-being. It is a practical choice for those seeking a foundational NAC supplement with added mineral benefits in a convenient 100-serving size.

thumb_upPros
  • Contains a standard and effective 600mg dose of NAC.
  • Includes L-Selenomethionine, a well-absorbed form of Selenium.
  • Reasonable price per serving for a 100-count bottle.
  • From a widely recognized and trusted brand.
  • Good for those who prefer a smaller quantity initially.
thumb_downCons
  • Molybdenum is in the less preferred Sodium Molybdate form.
  • Selenium dosage (25mcg) is on the lower side.
  • Price per serving is higher than the larger 250-count option from the same brand, offering less long-term value.
warningWarnings
  • NAC may cause mild gastrointestinal upset; taking it with food might help.
  • Consult with a healthcare professional before starting any new supplement, especially if you have existing health conditions.
  • A sulfur-like odor is normal for NAC and does not indicate spoilage of the product.
