Omega 3 and psoriasis: what should you know?

Omega 3 fats are found in foods such as oily fish, some seeds and fortified products. They are involved in normal cell and immune functions. Psoriasis is an inflammatory skin condition, so people often ask whether changing dietary fat intake can ease flares. A supplement may be useful for some people, but its effect on plaques, itching or scaling is not predictable. It also cannot confirm whether a rash is psoriasis; a clinician may need to examine the skin.

Active psoriasis can involve dry, red, itchy or scaly patches, and scratching may lead to cracking. Explore more about [Psoriasis](/conditions/psoriasis/) and related concerns such as [Dry Skin](/symptoms/dry-skin/) or [Itchy Skin](/symptoms/itchy-skin/).

Keep prescribed creams, tablets or light-based treatment consistent unless your clinician changes them. If you are considering an omega 3 supplement, share the product, dose and other medicines with a doctor or pharmacist first. This matters especially if you use medicine that affects bleeding, have a planned procedure, or have a condition requiring dietary advice. Food choices can be discussed as part of a balanced eating pattern; avoid treating a supplement as a quick fix.

Use a plain moisturiser regularly and avoid picking scales. Note where plaques appear, how itchy or cracked they become, and whether a new product or illness preceded a flare. [Cracked Skin](/symptoms/skin-cracking/) and [Scaly Skin](/symptoms/skin-scaling/) can help you describe what you are seeing.

Arrange a dermatology review if the diagnosis is uncertain, plaques are spreading, or symptoms interfere with sleep, work or movement. Seek prompt medical attention for rapidly worsening redness, marked warmth, pus, fever, extensive skin peeling, or painful cracks that do not settle. Sudden widespread redness with feeling unwell needs urgent assessment. Psoriasis can also affect joints, so report new swelling, stiffness or pain rather than managing it with supplements alone.

Ask whether omega 3 is appropriate with your medicines, whether your skin findings fit psoriasis, and which treatment is best for the body areas involved. You can also ask how to moisturise during a flare and what changes should trigger an earlier appointment.
