What supplements have evidence for psoriasis management?

Vitamin D, omega-3 fatty acids (high-dose EPA), curcumin, and oral nicotinamide have clinical evidence for supporting psoriasis management. Vitamin D is of particular interest since vitamin D analogs are established topical psoriasis treatments. Omega-3s at 3–4 grams EPA+DHA daily have shown modest improvements in some trials.

Can supplements alone treat psoriasis?

No. Psoriasis is a chronic autoimmune condition requiring medical management. Mild cases may respond to topical treatments (corticosteroids, vitamin D analogs, retinoids). Moderate to severe psoriasis often requires phototherapy, systemic medications, or biologics. Supplements may provide modest adjunctive benefits but cannot control the autoimmune inflammation driving the disease.

When should someone with psoriasis see a dermatologist about supplements?

All psoriasis patients should be under dermatological care. See a dermatologist for new or worsening plaques, joint symptoms (psoriatic arthritis), nail involvement, or psoriasis affecting quality of life. Some supplements may interact with immunosuppressive psoriasis medications. Never replace prescribed treatments with supplements.
