The efficacy of different supplements for improving symptoms or disease activity is unclear. There have been some pilot trials, but most of them have been limited by a small sample size, short duration, and/or lack of appropriate blinding.
The following supplements have been studied in preliminary trials for psoriatic arthritis:[1]
- Vitamin D
- Omega-3 fatty acids
- Primrose oil
- Gamma linolenic acid
- Coenzyme Q10, vitamin E, and selenium aspartate (in combination)
- Tripterygium wilfordii (i.e., thunder god vine)
- Paeony
- Curcumin
