Study says Ahiflower oil matched fish oil in mouse heart-health tests

A new animal study in Journal of Functional Foods found Ahiflower® oil produced cardiovascular and vascular benefits comparable to fish oil in mice fed a high-fat diet. The results could bolster interest in plant-based omega-3 sources for supporting blood lipids, circulation and platelet health.

Why it matters: - The findings add to evidence that plant-based omega-3 sources may support cardiometabolic and vascular health. - The study suggests Ahiflower oil could offer a fish-free option for people looking for omega nutrition through supplements, foods or beverages. - The results matter because the measured effects included blood lipids, vessel function and platelet activity, not just one health marker.

What happened: - Researchers published a 12-week dietary study in Journal of Functional Foods on Ahiflower® oil, a plant-based omega-3 and GLA source from Buglossoides arvensis. - The study tested Ahiflower oil in mouse models of high blood lipids and thrombosis. - The trial compared Ahiflower oil directly with fish oil for the first time in an animal study focused on heart-health outcomes. - Researchers examined markers linked to a high-fat Western diet, including blood lipids, inflammation and clot formation.

The details: - Mice receiving Ahiflower oil with a high-fat diet showed lower triglycerides, total cholesterol and LDL cholesterol. - The same mice showed higher HDL cholesterol and improved liver enzyme markers, including ALT and AST. - Ahiflower oil also improved markers of blood vessel function and reduced signals tied to vascular inflammation. - The study found increased signals related to nitric oxide, which supports healthy circulation. - In thrombosis-related models, Ahiflower oil reduced platelet aggregation, or the tendency of platelets to clump together. - The benefits also appeared in an inflammation-driven model even when blood lipid levels did not change much. - The study used an Ahiflower oil dose equivalent to about 1.0 to 2.5 grams per day in humans. - That amount can be reached through dietary supplements and certain foods and beverages. - When fish oil was tested directly, both oils showed similar benefits across blood vessel function, platelet aggregation and blood lipid levels. - Ahiflower oil produced those effects without EPA or DHA. - Ahiflower oil instead contains ALA, SDA and GLA.

Between the lines: - The study suggests Ahiflower oil may influence multiple pathways tied to cardiovascular and vascular health, not only omega-3 status. - The results support the idea that plant-based omega sources may complement preformed EPA and DHA rather than simply replacing them. - The direct comparison with fish oil gives the findings more relevance for nutrition products aimed at consumers seeking plant-based alternatives.

What's next: - Further research will likely need to test whether the same effects appear in humans. - Additional studies could help clarify how Ahiflower oil compares with fish oil across longer time frames and different health populations. - Interest may grow in supplement and food applications that combine plant-based precursor fatty acids with other omega-3 strategies.

The bottom line: - In this mouse study, Ahiflower oil delivered heart- and vessel-related benefits that were broadly comparable to fish oil, supporting its case as a plant-based omega option.
