Psoriasis is more than just a skin condition—it’s an autoimmune disorder that is deeply connected to nutrition and gut health. Many people focus on creams and medications, but few realize that nutritional deficiencies play a major role in psoriasis flare-ups. Addressing these deficiencies can be a powerful way to reduce inflammation naturally and improve symptoms.

What Nutritional Deficiencies Are Common in Psoriasis?

The most common deficiencies in psoriasis include vitamins D3 and B12, minerals like magnesium and zinc, and a lack of phytonutrients—plant-based compounds that help regulate inflammation. These nutrients are essential for immune balance and skin repair.

Key Deficiencies in Psoriasis:

• Vitamins: D3, B12
• Minerals: Magnesium, Zinc, Selenium
• Phytonutrients: Terpenes, Polyphenols, Chlorophyll, Isothiocyanates, Phyto Oils

Each of these nutrients plays a critical role in controlling inflammation, supporting gut health, and preventing psoriasis flare-ups.

How Do Vitamin Deficiencies Affect Psoriasis?

Vitamin D3: The Anti-Inflammatory Powerhouse

Vitamin D3 is crucial for immune system regulation and reducing inflammation. Studies show that people with psoriasis often have low vitamin D levels, which can lead to worsening skin symptoms.

• Best Sources: Sunlight, fortified plant-based milk, mushrooms, and supplements.
• Optimal Intake: 2,000–5,000 IU daily, depending on deficiency levels.

Vitamin B12: Essential for Skin and Nerve Health

B12 plays a role in cell regeneration and immune function. A deficiency can lead to skin irritation, fatigue, and nervous system issues, all of which can make psoriasis worse.

• Best Sources: Nutritional yeast, fortified cereals, plant-based supplements.
• Optimal Intake: 1,000 mcg daily (if deficient).

How Do Mineral Deficiencies Impact Psoriasis?

Magnesium: The Stress-Reducing Mineral

Magnesium helps regulate stress, muscle function, and immune balance. Since stress is a major psoriasis trigger, low magnesium levels can contribute to more frequent flare-ups.

• Best Sources: Leafy greens, nuts, seeds, legumes.
• Optimal Intake: 300–400 mg per day.

Zinc and Selenium: The Skin-Healing Duo

Zinc is needed for wound healing and immune function, while selenium has antioxidant properties that reduce inflammation and oxidative stress.

• Best Sources: Pumpkin seeds, Brazil nuts, whole grains, legumes.
• Optimal Intake: Zinc (8–11 mg/day), Selenium (55 mcg/day).

What Are Phytonutrients and Why Do They Matter for Psoriasis?

Phytonutrients are plant-based compounds that have powerful anti-inflammatory, antioxidant, and immune-supporting properties. They help heal the gut, which in turn reduces psoriasis symptoms.

Top Phytonutrients for Psoriasis:

Terpenes (Brain & Gut Health)

• Found in: Mushrooms, citrus zest, peppermint, basil, ginseng
• Benefits: Supports nerve function, digestion, and mood

Polyphenols (Antioxidant Protection)

• Found in: Berries, green tea, turmeric, cinnamon
• Benefits: Reduces oxidative stress and inflammation

Chlorophyll (Detox & Skin Repair)

• Found in: Leafy greens, wheatgrass, seaweed
• Benefits: Eliminates toxins, improves immune function

Isothiocyanates (Liver Support)

• Found in: Broccoli sprouts, kale, cabbage, brussels sprouts
• Benefits: Aids detoxification and inflammation control

Phyto Oils (Healthy Fats for Skin & Immunity)

• Found in: Flaxseeds, walnuts, avocados, extra virgin olive oil
• Benefits: Supports cellular repair and reduces inflammation

How Can You Fix Nutritional Deficiencies for Psoriasis?

Improving psoriasis naturally involves making small but effective dietary changes:

Increase plant-based, whole-food nutrition with a variety of colorful fruits and vegetables. Prioritize gut health by reducing sugar and processed foods while increasing fiber and probiotics. Supplement when necessary—especially for vitamin D, B12, magnesium, and zinc. Hydrate properly, as dehydration can make inflammation worse. Reduce inflammatory triggers like dairy, processed meats, and gluten if they worsen symptoms.

Taking Control of Your Health

Correcting nutritional deficiencies is a key step toward reducing inflammation and managing psoriasis naturally. By improving your diet with vitamins, minerals, and phytonutrients, you can take control of your symptoms and support long-term healing.

FAQs Section

What is the best diet for psoriasis? A diet rich in phytonutrients, healthy fats, and fiber while avoiding processed foods, sugar, and inflammatory fats is ideal.

Can vitamin D help psoriasis? Yes! Vitamin D3 is essential for immune balance and skin health. Sun exposure and supplementation can help improve symptoms.

How long does it take to see improvement from diet changes? Most people notice changes within 4–6 weeks of making dietary adjustments and correcting deficiencies.

Can gut health really improve psoriasis? Absolutely. Since 70–80% of the immune system is in the gut, improving digestion and microbiome balance directly impacts psoriasis severity.

Are there specific foods to avoid for psoriasis? Yes—processed foods, refined sugars, dairy, gluten, and excess animal fats can trigger inflammation and worsen symptoms.
