    Omega-3 Fatty Acids for Sjögren's Syndrome

    Omega-3 supplements have not demonstrated meaningful improvement in the hallmark dryness symptoms of Sjögren's syndrome.

    Overview

    Omega-3 supplements have not demonstrated meaningful improvement in the hallmark dryness symptoms of Sjögren's syndrome.

    Verdict

    Insufficient evidence

    How It Works

    Sjögren's is an autoimmune disease targeting moisture-producing glands. Omega-3 fatty acids have general anti-inflammatory effects via resolvin pathways, which prompted interest in reducing glandular inflammation.

    Evidence is insufficient: omega-3 trials in dry eye disease, notably the large DREAM study using 3 g/day combined EPA+DHA, found no benefit over placebo, and no trial has established benefit specifically in Sjogren syndrome. Artificial tears, punctal plugs, ciclosporin or lifitegrast drops, pilocarpine for dry mouth and hydroxychloroquine for systemic features are the options with evidence.

    Evidence

    What the studies say

    Several small trials of omega-3 in Sjögren's have failed to show consistent improvement in tear or saliva production or validated dryness scores. Standard care — preservative-free artificial tears, saliva substitutes, pilocarpine or cevimeline, and hydroxychloroquine for systemic features — remains the evidence base. Vitamin D deficiency is common and worth screening. New dry eyes plus dry mouth in middle age warrants rheumatology assessment; dryness with joint pain or fatigue suggests systemic disease.

    High-dose omega-3 did not relieve dry eye symptoms beyond placebo.

    Safety

    Caveats

    Sjogren syndrome needs rheumatological follow-up: it raises lymphoma risk and can involve kidneys and lungs. Persistent dry mouth accelerates dental decay - dental review matters more than a supplement. Safety ceiling: below 3 g/day EPA+DHA without supervision; higher raises bleeding risk with anticoagulants and antiplatelets and should be stopped before surgery. Standard doses acceptable in pregnancy, but anti-Ro/La antibodies require fetal cardiac monitoring - see a specialist.

    Less likely to help if

    Everyone: the definitive dry-eye trial at 3 g/day found no benefit over placebo.
