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.

Data coverage and detailed study classifications
Paper counts are separated by research topic below. One paper may contribute to multiple findings.
Analysis status: Public-ready
Ingredient analysis date:
How the grade was determined: C
The 33.7 evidence score includes 2 independent human studies and 2 clinical studies in the representative benefit area. The C tier remains conservative because of limited repetition across independent human clinical studies, limited repeated evidence for directly felt outcomes.
The grade is based mainly on the research area with the most evidence. It does not mean the same result was found in other areas.

How to read research findings
How should I read research findings?
Research guidesNo clear difference and an uninterpretable result are different
A reported null comparison contains a result. An abstract without an interpretable comparison leaves a question unresolved.
Paper counts and study counts are different
Count original research separately from research that reanalyzes it. Publication volume is neither replication nor a quality rating.
Side effects and combination findings
Findings from this ingredient alone are shown separately from those involving another supplement or medication.
No combination cautions are available to show in the current data. This does not guarantee safety.
Review 1 combination findings and 0 findings that outperformed an ingredient alone.
Reported improvements with combinations
Combination findings are grouped by how the study compared them. This is not a recommendation to combine ingredients.
Combinations with reported improvement
The combination showed improvement, but each ingredient's contribution is unclear.
Iron sulfateOral taurine demonstrated a statistically significant additive positive effect on hemoglobin, RBC count, and serum ferritin when co-administered with iron sulfate compared to iron sulfate alone.
