If you want to check out the testing for specific supplements go to the Consumer Lab's website. There is a small fee for subscribing to the website. Consumer Labs also has recommendations for specific vendors that it has found sufficient quality control (available without charge).

This is really important for folks with developmental disorders and mental illness.
