Testing & Certifications Explained

Consumers should be aware that the absence of third-party testing increases the risk of inaccurate labeling or contamination. The question of "is Great Earth third-party tested?" is answered negatively.

How Great Earth Compares

Compared to other brands in the specialty supplement category, Great Earth's trust score of 50/100 is lower than brands that prioritize third-party testing. For example, a brand like Thorne Research (trust score 90/100) is fully third-party tested and GMP certified. Another competitor, NOW Foods (trust score 75/100), also has more visible certifications. This suggests that Great Earth lags behind competitors in demonstrating product quality and safety.
