The Role of Vitamin D and Other Nutrients in Psoriasis: Natural Sources and Supportive Approaches

Vitamin D plays a central role in psoriasis management due to its immune-modulating effects. People with psoriasis often have lower vitamin D levels, and deficiency can worsen inflammation and flares.
Vitamin D: Why It Matters for Psoriasis
Mechanism — Vitamin D receptors are present on skin cells and immune cells. It helps regulate keratinocyte (skin cell) growth, reduces pro-inflammatory cytokines (like IL-17 and IL-23), and promotes anti-inflammatory pathways.
Topical Vitamin D Analogs — Prescription creams like calcipotriene (Dovonex) or calcitriol are standard treatments, often combined with steroids for better results.
Oral Vitamin D Supplementation — Many studies show that correcting deficiency (common in psoriasis patients) can improve symptoms. Doses of 1,000–4,000 IU daily (or higher under medical supervision) are often used, with blood tests to monitor levels. Some people report reduced scaling and itch after months of supplementation, especially when levels reach optimal range (50–80 ng/mL).
Natural Sources of Vitamin D
Sunlight — 10–30 minutes of midday sun exposure (arms and legs) several times a week can boost levels (depending on skin tone, location, and season).
Foods — Fatty fish (salmon, mackerel, sardines), egg yolks, fortified dairy or plant milks, mushrooms exposed to UV light.
Other Helpful Vitamins and Nutrients
Omega-3 Fatty Acids — Found in fatty fish, flaxseeds, chia seeds, walnuts. They reduce inflammation and may lower IL-17/IL-23 activity.
Vitamin A — From sweet potatoes, carrots, spinach, and liver. Supports skin health but avoid excess supplementation.
Vitamin E — In nuts, seeds, spinach, and avocados. Acts as an antioxidant to protect skin cells.
Zinc — From oysters, pumpkin seeds, lentils. Supports immune balance and wound healing.
Selenium — In Brazil nuts, fish, eggs. Helps reduce oxidative stress.
Antioxidants — From berries, green tea, turmeric (curcumin), and broccoli. These combat inflammation naturally.
Combining these with an anti-inflammatory diet (like Mediterranean) amplifies benefits. Many people find gradual improvements in plaques and overall energy by focusing on nutrient-rich foods and addressing deficiencies.

Addressing nutrient needs holistically—through food first, then targeted supplements under guidance—can be a supportive part of psoriasis care.
