CAN OMEGA-3 FATTY ACID HELPS WITH ECZEMA?

Yes, omega-3 fatty acids may help eczema in some people, but the evidence is not strong enough to consider omega-3 a proven treatment for eczema.

How might omega-3 help eczema?

Eczema (atopic dermatitis) involves skin-barrier dysfunction and an overactive inflammatory response. EPA and DHA may influence this inflammation.

A simplified pathway is:

EPA/DHA → altered inflammatory signaling → potentially less inflammatory activity → potentially less itching/redness

Omega-3 fatty acids may also contribute to maintaining healthy cell membranes and skin-barrier function. Research on topical omega-3s is promising, but more clinical trials are needed. (PubMed)

What does the clinical evidence show?

The evidence is mixed.

Reviews of clinical trials have generally found that fish oil/omega-3 supplementation does not consistently improve eczema severity. A recent systematic review concluded that evidence for nutritional supplements in atopic dermatitis remains weak overall. (PubMed)

There are, however, some encouraging individual studies. For example, a 2024 study in children found improvement after a combination containing omega-3 + GLA + vitamin D, but because several ingredients were given together, it cannot establish that omega-3 alone caused the improvement. (PubMed)

🐟 What about eating fish?

This is different from taking a high-dose supplement.

Including oily fish such as salmon, sardines and mackerel in a balanced diet provides EPA and DHA along with protein and other nutrients. This is generally a sensible way to obtain omega-3.

What should someone with eczema prioritize?

For established eczema, omega-3 should be considered supportive nutrition rather than primary treatment.

The fundamentals remain:

1. Moisturize regularly with a fragrance-free cream or ointment.
2. Avoid known irritants and personal triggers.
3. Treat active inflammation appropriately with dermatologist-recommended topical medication.
4. Maintain a balanced diet containing adequate omega-3.
5. Don't eliminate foods unnecessarily unless a genuine food allergy has been identified.

The American Academy of Dermatology emphasizes regular moisturizing and evidence-based topical/systemic treatments for atopic dermatitis. (American Academy of Dermatology)

For an older woman with eczema

If the goal is skin health + healthy aging, getting adequate omega-3—particularly EPA and DHA—may be worthwhile for its broader nutritional benefits, but I would not take a high-dose omega-3 supplement solely to treat eczema.
