Who should take Klean Antioxidant?

Athletes with high training volume, endurance athletes, those exposed to environmental oxidative stress, and anyone wanting broad-spectrum antioxidant support beyond what diet provides.

When should I take Klean Antioxidant?

Take with a meal for optimal absorption. Time of day is flexible; consistency matters more than exact timing.

Does antioxidant supplementation blunt training adaptation?

Research is mixed. High-dose isolated vitamin C or E immediately post-workout may blunt some adaptations. Klean Antioxidant provides a balanced multi-nutrient blend rather than mega-doses, which minimizes this concern.

Is Klean Antioxidant NSF Certified for Sport?

Yes. Every batch is tested and certified through NSF Certified for Sport, verifying content, purity, and freedom from banned substances.
