Polydatin

Summary

Polydatin (piceid, 3,4',5-trihydroxystilbene-3-beta-D-glucoside) is a stilbene glucoside isolated from Polygonum cuspidatum and also found in grapes, peanuts, hop cones, red wine and cocoa products; it is not a peptide. · pmid:23862567

History

A review of research since 1990, drawing on English- and Chinese-language databases including CNKI, found studies centred on cardiovascular effects, neuroprotection, anti-inflammatory and antioxidant actions, and liver and lung protection. · pmid:23862567

Where the evidence actually sits

Proportion of the 1 claim about Polydatin standing at each tier. Community volume is shown on the Consensus tab beside this and is never averaged into it.

Structure

No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for Polydatin yet.

Dose evidence, rung by rung

No established safe human dose. Nothing on file establishes one. That is a statement about the evidence PepJunkie holds, not a promise about the molecule.

1. Approved-label dose · a resolved regulatory document names a labelled dose

   nothing resolved on this rung

2. Studied human doses · resolved human studies at the established tier

   nothing resolved on this rung

3. Observational evidence · resolved human data at the emerging tier: thin, or contested

   nothing resolved on this rung

4. Community-reported protocols · protocol propositions from distinct members, counted once per human

   nothing resolved on this rung

5. Preclinical evidence · resolved animal, cell or mechanistic work
