What do these mean? ▾

Beneficial. Linked to benefits in published research. Tiers show evidence strength.

Restricted or banned. Restricted or banned by a regulator in at least one country.

Under research review. Being studied or re-evaluated by researchers or regulators.

Contextual. Not flagged, but there is a note worth reading.

Standard. Everyday components like vitamins and minerals.
