  • Antioxidant Protection — Vitamin C and NAC are both antioxidants that neutralize harmful free radicals.*
  • Detoxification Support —   Animal and human studies have demonstrated that both vitamin C and NAC help the body detoxify a range of pollutants, including heavy metals, automobile exhaust, tobacco smoke, industrial chemicals, and pesticides.*
  • Immune Support —   Human clinical trials have shown that daily intake of vitamin C during the cold-weather season can promote immune response.* A placebo-controlled study also found that people who took NAC in the winter maintained their well-being.*

Why Fast-C? It delivers 54% more vitamin C into the tissues in the first 2 hours vs. the leading premium brand. It's buffered —  No upset stomach and no heartburn.
