Quick answer
Why is Affron different from many generic saffron supplements?
Because Affron is a studied extract with published standardization language, named human trials, and a clearer ingredient identity. Generic saffron extract is a broader market category that may include different extraction styles, different composition targets, blends, inconsistent labeling, or products that simply do not match the extract used in a trial.
That does not prove generic saffron never works. It does mean that research on a named extract should be applied carefully rather than copied onto every saffron product by default.
