Omega-3 Interactions

Alcohol raises blood triglycerides through liver metabolism, which may partly offset one of omega-3's main benefits.

Fat from omega-3 supports absorption of the fat-soluble vitamin D

Phosphatidylserine and omega-3 fatty acids (especially DHA) are both core structural components of neuronal membranes, and a PS-DHA form mirrors the way the two naturally occur together in brain phospholipids. In older adults with subjective memory complaints, supplementing the pair has shown modest, mostly subgroup-level improvements in memory measures, though the strongest single figures come from small, uncontrolled studies and the placebo-controlled evidence is weaker than the synergy is sometimes presented to be.

Omega-3 fatty acids (EPA and DHA) and curcumin lower inflammation through complementary pathways — omega-3s remodel cell membranes and generate specialized pro-resolving mediators, while curcumin inhibits NF-kB and downstream inflammatory cytokine signaling. Human trials in migraine patients show the combination can reduce inflammatory markers more than either alone.

Omega-3 fatty acids (EPA and DHA) are polyunsaturated and highly susceptible to oxidation, which can blunt their cardiovascular and anti-inflammatory benefits. Vitamin E acts as a lipid-soluble antioxidant that helps protect omega-3 fatty acids from peroxidation both during storage and after absorption, which is why most quality fish oils already include a small amount of mixed tocopherols.

Boswellic acids inhibit 5-lipoxygenase to reduce pro-inflammatory leukotrienes, while EPA and DHA from omega-3s lower the arachidonic acid available to inflammatory enzymes and serve as substrates for specialized pro-resolving mediators (resolvins, protectins) that help switch inflammation off. The two act at different steps of the same lipid cascade, giving complementary anti-inflammatory coverage. Evidence in joint pain is modest but consistent.
