About CTD

CTD is a US-based specialty supplement brand operating independently. The founding date of CTD is unknown. They offer a range of supplements in the specialty category.

Product Specialization

CTD specializes in specialty supplements. Specific product types are not specified, but the focus is on supplements outside of mainstream categories like vitamins or protein.

Testing & Certifications Explained

CTD does not have any third-party testing certifications on record. This means that no independent organization has verified the quality, purity, or potency of CTD's products. Consumers should be aware that the absence of third-party testing increases the risk of inaccurate labeling or contamination. Therefore, it is difficult to verify if CTD is third-party tested.

How CTD Compares

Compared to other brands in the specialty supplement category, CTD's trust score of 50/100 is lower than brands with verified third-party testing. For example, a brand like Klean Athlete (trust score 85/100) has NSF Certified for Sport certification, while Garden of Life (trust score 78/100) has multiple certifications. This difference highlights the importance of independent verification in building consumer trust.

Buying Guidance

Given CTD's trust score and lack of third-party testing, consumers should exercise caution when purchasing CTD products. Purchase from reputable retailers and carefully examine product labels. Consider choosing third-party tested supplements from brands with higher trust scores for greater assurance of quality and safety.
