• Thunder god vinePreliminary or mixed

  NCCIH: may help some symptoms and add to standard treatment; low-to-moderate quality studies and serious toxicity.

• Fish oilPreliminary or mixed

  Reviews suggest less pain and joint swelling with omega-3-rich foods; evidence is low quality.

• Omega-3 fatty acids (ALA, EPA and DHA)Preliminary or mixed

  Omega-3-rich diets may ease joint symptoms; evidence is low quality.

• Peony (white peony root)Preliminary or mixed

  A 2021 review found fewer liver side effects and less leukopenia when the extract was added to arthritis drugs; no placebo-controlled studies of the root exist.

• BoragePreliminary or mixed

  Cochrane: moderate evidence that GLA oils including borage seed oil give some symptom relief; few trials.

• UC-II (Undenatured Type II Collagen)Preliminary or mixed

  Two 1990s trials of oral type II collagen gave mixed results (one benefit in severe disease, one no significant difference in early disease). These do not show modern UC-II is useful or safe here; ask a clinician first.
