About ProSol

ProSol is an independent supplement brand operating in the US. The company's founding date is unknown. ProSol offers products in the specialty supplement category.

Product Specialization

ProSol specializes in specialty supplements. Specific product types are not detailed in the available information.

Testing & Certifications Explained

ProSol does not have any third-party testing certifications on record. This means that there is no independent organization verifying the quality, purity, or potency of ProSol's supplements. Consumers should be aware that the claims made by ProSol have not been validated by an independent source, and it's difficult to determine if ProSol is third-party tested.

How ProSol Compares

Compared to other brands in the specialty supplement category, ProSol's trust score of 50/100 is lower than brands that prioritize third-party testing. For example, a brand like Klean Athlete (trust score 85/100) has NSF Certified for Sport certification. Another competitor, Thorne Research (trust score 92/100), publishes extensive lab results and has multiple certifications. This makes it easier for consumers to assess if Thorne Research is a good brand.

Buying Guidance

Given ProSol's trust score and lack of third-party testing, consumers should exercise caution when purchasing their products. Buy directly from ProSol or authorized retailers to minimize the risk of counterfeit products. Carefully examine product labels and research individual ingredients before use.
