Testing & Certifications Explained

Amazing Grass is USDA Organic and GMP Certified. USDA Organic certification ensures that products are produced using agricultural practices that promote ecological balance and conserve biodiversity.

Amazing Grass falls in the middle, with a B+ grade. Garden of Life distinguishes itself with more rigorous third-party testing, while Nested Naturals shares a similar lack of third-party verification.
