Algal oil is primarily valued for its high content of omega-3 polyunsaturated fatty acids, especially docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Scientific interest in algal oil for psoriasis arises from the established role of omega-3 fatty acids in modulating inflammation, a key factor in psoriasis pathogenesis. Several studies on fish oil (another rich source of EPA and DHA) have shown moderate benefits in reducing the severity and extent of psoriatic lesions, likely due to their anti-inflammatory effects, such as reducing pro-inflammatory cytokines and leukotriene synthesis.

Algal oil offers a plant-based, sustainable alternative to fish oil, delivering similar omega-3s without the risk of ocean contaminants. However, direct clinical evidence supporting algal oil specifically for psoriasis is limited. Most supportive data are extrapolated from fish oil studies or from general observations about omega-3 fatty acids’ benefits in inflammatory skin diseases. Only a few small studies and case reports have evaluated algal oil in dermatological contexts, and none provide strong, psoriasis-specific outcomes.

In summary, while the anti-inflammatory properties of algal oil’s omega-3s provide a plausible rationale for its use in psoriasis, direct scientific validation is currently modest. The evidence base is primarily indirect, and more robust, controlled trials are needed to determine its true efficacy for this indication.
