This grouping is Tavita's own editorial reading of NIH Office of Dietary Supplements fact sheets — it isn't a transcription of a single published table. The established or emerging label next to each nutrient reflects the strength of the evidence behind it, not a guarantee of an effect for you. See the methodology page for how the library is built and verified.

This is educational information, not medical advice. Talk to your clinician before changing your supplement routine, especially if you take medication or manage a condition.
