Understanding Coq10 Score
The CoQ10 Score is a simple 1-to-10 rating system designed to measure the purity, accuracy, and overall quality of CoQ10 supplements available on the market. It helps consumers understand what they are actually buying, how much CoQ10 is in the product, whether that amount matches what is stated on the label, and whether the manufacturer’s claims hold up under independent testing.
Rating

Each product receives a score from 1 to 10, with 1 representing the lowest level of accuracy and purity and 10 representing the highest. We compare the amount of CoQ10 found during testing with the amount advertised on the label. Products that contain the advertised amount receive full points for accuracy. Points are deducted when testing finds less CoQ10 than advertised, unexpected fillers, heavy metals, contaminants, or other differences between the contents of the product and the claims made on its packaging. This gives consumers a quick and simple way to compare CoQ10 supplements and see which products actually deliver what they promise.
Up to five points are awarded for label accuracy and brand transparency. When independent testing confirms that the amount of CoQ10 in the product matches the amount stated on the label, the product can earn all five points. If testing finds consistent discrepancies or lower levels of CoQ10 than advertised, points are deducted based on the results. The remaining five points are based on purity, manufacturing quality, and consumer safety. We review factors including manufacturing standards, facility certifications, fillers and additives, recall history, and testing for heavy metals and other potentially harmful contaminants. Products with accurate labeling, high purity, responsible manufacturing practices, and no concerning contaminants can earn the full 10-point CoQ10 Score.
