Nutrition and Psoriasis: Can Diet and Supplements Help?

Psoriasis is a chronic inflammatory skin condition. While standard treatments exist, research suggests that certain nutrients and dietary strategies may help reduce symptoms. Clinical trials have studied vitamin D, omega-3 fatty acids (fish oil), gluten-free diets, and B-vitamin supplementation as possible supportive therapies.

Vitamin D and Psoriasis

  • Topical Vitamin D3 Analogs
    In a 2007 British Journal of Dermatology study, patients with plaque psoriasis used vitamin D3 cream for 8 weeks.
    • High-dose treatment: 26% were clear or nearly clear of lesions.
    • Placebo: No improvement.
  • UV Light and Vitamin D
    UV therapy may work partly by boosting vitamin D in the skin (Cutis, 1993).
  • Vitamin D Deficiency
    A study in Acta Derm Venereol (1987) showed lower vitamin D levels in psoriasis patients compared to healthy controls.

Omega-3 Fatty Acids (Fish Oil) and Psoriasis

  • High-Dose Benefits
    In a 1993 Clinical Investigator trial, patients consuming high-dose fish oil (EPA + DHA) saw 45–75% improvement in symptoms within 10 days.
  • Low-Dose Limitations
    Smaller amounts of fish oil showed little effect, suggesting that dose matters.

Gluten-Free Diet and Psoriasis

A 2003 study (Acta Derm Venereol) found that a gluten-free diet improved psoriasis in some patients, especially those with gluten sensitivity.

Homocysteine, B-Vitamins, and Psoriasis

  • Psoriasis patients often have higher homocysteine levels (British Journal of Dermatology, 2006).
  • More severe psoriasis = higher homocysteine.
  • Since vitamins B6, B12, and folate help lower homocysteine, supplementation may support skin health.

Conclusion:Nutrition and Psoriasis Research

Emerging research suggests that nutrition and psoriasis are linked. Vitamin D, omega-3 fatty acids, gluten-free diets, and B-vitamins may offer measurable benefits. These strategies should be considered as complementary therapies, not replacements for standard medical care.
