6 Vegetarian Sources of Omega-3s
Typically found in oily fish, omega-3s are important for your heart, brain, eyes, and more. But there are plenty of plant-based sources, too.

If your omega-3 strategy begins and ends with a salmon fillet, you're leaving a lot of nutritional ground uncovered — and if you don't eat fish at all, you may be missing the nutrient entirely without realizing it. Omega-3s support brain function, cardiovascular health, and eye health, and while oily fish gets most of the credit, plant-based sources deliver a form called ALA that counts toward your daily needs. According to Vogue, the NIH recommends 1.6g of ALA daily for adult men and 1.1g for women, with slightly higher targets during pregnancy and lactation.
The Plant-Based Lineup Worth Knowing
The most potent option by volume is flaxseed oil — one tablespoon delivers 7.26g of ALA, making it nearly impossible to miss your daily target. It's also been linked to improved skin barrier function, which is a quiet bonus. Flaxseeds themselves offer fiber and gut health benefits, but the oil is the more bioavailable form if omega-3 intake is your actual goal. Chia seeds come in second at 5.05g of ALA per ounce, plus nearly 10g of fiber and solid protein — genuinely one of the more efficient ingredients you can add to a morning routine without thinking about it. Hemp seeds are quieter but surprisingly impressive: three tablespoons contain 2.6g of ALA, more protein than a large egg, roughly two-thirds of the recommended daily magnesium for women over 30, and about 85% of the potassium in a medium banana. They also carry omega-6 fatty acids, which Harvard Medical School noted in 2019 can lower LDL and raise HDL cholesterol.
Walnuts offer 2.57g of ALA per ounce alongside polyphenols — antioxidants that reduce inflammation and oxidative stress — with a 2023 Nutrients study linking them to lower LDL cholesterol. Soybean oil clocks in at 0.92g per tablespoon; despite the ongoing backlash against seed oils, Harvard Medical School's 2025 guidance is clear that using a few tablespoons for cooking or dressing is a perfectly healthy choice. And then there's algal oil, arguably the most interesting option on the list. As sports medicine physician and holistic pain management expert Dr. Reuben Chen explained to Vogue, algae is the original source of EPA and DHA — the forms of omega-3 that fish accumulate by eating it — so supplementing with algal oil means going straight to the source. Consult your doctor before adding any supplement to your routine.
You don't need fish to build a solid omega-3 foundation — you just need to know where to actually look.
