Skincare is the cornerstone
For eczema, the proven basics come first: frequent moisturizing (emollients), gentle cleansing, avoiding triggers, and prescribed treatments during flares. Supplements are a supporting layer with modest, mixed evidence [3].
Supplements with the most research
- Omega-3s may support a healthier inflammatory balance relevant to barrier-related skin issues [2].
- Vitamin D is worth correcting if low, given its immune and skin roles.
- Probiotics have been studied for eczema, especially in children and prevention contexts, with mixed results [1].
More preliminary options
- Evening primrose oil (GLA) is popular for eczema, but evidence has been disappointing in reviews.
- Ceramides (oral) are an emerging skin-barrier ingredient with limited data; topical ceramide moisturizers are better established.
- Zinc and hemp seed oil are sometimes used, with limited evidence.
Safety and the bigger picture
These are generally well tolerated, though omega-3s can add to blood thinners and probiotics warrant caution in immunocompromised people. Most importantly, supplements shouldn't delay effective eczema care — infected, weeping, or severe eczema needs prompt medical attention.
Practical guidance
Moisturize consistently and follow your clinician's flare plan; correct a vitamin D shortfall and support omega-3 intake; treat probiotics and evening primrose as experiments with modest expectations; and see a dermatologist for persistent, severe, or infected eczema.
