Yes. Zena holds 2 verified third-party certifications: NSF Certified, USDA Organic. Third-party testing means an independent laboratory — not the supplement company itself — has verified the product's contents, purity, and/or manufacturing practices. This is one of the strongest indicators of supplement quality because it removes the conflict of interest inherent in self-testing. Not all certifications are equal: NSF International and USP are considered the gold standard, while GMP certification indicates proper manufacturing practices.
