Testing & Certifications Explained

Consumers should be aware that the absence of third-party testing means the brand's claims are not independently validated.

How FNX Compares

Compared to other brands in the specialty supplement category, FNX's trust score of 50/100 places it lower than brands with verified certifications. For example, a brand like Klean Athlete (trust score 85+) has NSF Certified for Sport certification, while Garden of Life (trust score 70+) has certifications from organizations like Informed-Sport. These certifications provide a higher level of assurance compared to FNX.
