Analysis

This formula combines 500mg of NAC with 300mg of milk thistle seed extract to help the body produce antioxidants and support the liver. NAC is a key ingredient for glutathione synthesis, which is the body's primary detoxifier. Organic broccoli powder is also included to provide additional cellular support during metabolic processes.

This combination is well-suited for people who want more than just herbal support for their liver. The doses of both main ingredients are meaningful and fall within recognized ranges for metabolic health. It is a high-quality, transparent option for those focusing on internal clearance pathways.

  • Includes organic broccoli powder
  • High level of ingredient transparency

Cons

  • Milk thistle is not standardized to a silymarin percentage
  • Higher price per serving ($0.66)
  • Only 30 servings per bottle

Warnings

  • Take with plenty of water

N-acetyl cysteine and milk thistle seed extract are combined to support glutathione production and protect liver tissue. These ingredients facilitate the body's natural Phase II conjugation and provide antioxidant defense against metabolic byproducts.

The 500 mg dose of NAC provides a meaningful substrate for antioxidant synthesis. However, the lack of silymarin standardization makes it difficult to assess the exact therapeutic potency of the milk thistle component.
