Improvement after a supplement is not the same as a comparative result
Start with the comparison. A before-and-after change alone cannot isolate the contribution of an ingredient.

What does a research result actually tell you?
Reading researchNo significant difference and an unreadable result mean different things
A reported null comparison contains a result. An abstract without an interpretable comparison leaves a question unresolved.
Ten papers do not necessarily mean ten independent studies
Count original research separately from research that reanalyzes it. Publication volume is neither replication nor a quality rating.
