If you’re looking for ways to boost health, improve inflammation, and positively impact cardiovascular health, go no further than omega-3 fatty acids. They are essential for health but can only be obtained through diet since you don’t naturally produce them. While many of these sources are animal-based, you can still reap the benefits of a vegetarian or vegan diet. But before we explore some vegan omega-3 foods (and subsequent supplement options), let’s understand why omega-3s are important, how they benefit health, and what experts recommend for daily intake.
What are omega-3 fatty acids?
Omega-3 fatty acids are polyunsaturated fats that play essential roles in hormone production, inflammation, brain health, immunity
, fetal development, and blood clotting [1
]. Studies have also found that omega-3s positively impact cardiovascular health, as they help to reduce triglycerides, lessen the risk of arrhythmias, and slow plaque buildup (which can lead to atherosclerosis) [1
The three main omega-3 fatty acids are ALA, EPA, and DHA [5
ALA (alpha-linolenic acid):
This essential fatty acid is found in most plant foods and has been linked to a reduced risk of death from heart disease [9
EPA (eicosatetraenoic acid):
EPA occurs naturally in cold-water fatty fish (like salmon, mackerel, tuna, and sardines), seaweed, certain algae, and other animal products like enriched eggs, and meat and dairy from grass-fed animals. Research suggests that EPA may reduce inflammation and help with symptoms of depression [10
DHA (docosahexaenoic acid)
: DHA is also found in animal products (particularly cold-water fatty fish and shellfish) and has been shown to have positive effects on brain function, heart health, arthritis, high blood pressure, type 2 diabetes, and some cancers [11
How much omega-3 should you take each day?
While there are no official RDAs (recommended dietary allowances) for omega-3s, the IOM has established AIs (adequate intakes) for all ages based on omega-3 intakes in healthy populations [3
]. Currently, the AI for adult males is 1.6 g/day and 1.1 g/day for adult females but applies only to ALA because ALA is the only essential
omega-3 (meaning your body can’t make it). While the IOM does not have specific intake recommendations for EPA and DHA, which the body can only make in tiny amounts from ALA, evidence suggests an additional 250–500 mg/day of combined EPA and DHA can be beneficial for overall health [3
An omega-3 deficiency has been associated with depression, heart disease, arthritis, and various cancers [6,7,8].
Dietary sources of omega-3 fats
Since your body can’t produce all omega-3 fatty acids on its own, you must rely on dietary sources and/or supplements to meet your needs.
Fatty fish (such as salmon, trout, tuna, and sardines) and fish oil are excellent sources of DHA and EPA, while nuts, seeds, and flaxseed oil are rich in ALA [3
]. You can also use a fish oil supplement to fill in the gaps. However, if you follow a vegetarian or vegan diet, you may find it challenging to meet your omega-3 needs. Thankfully, you can still get your Omega-3s as a plant-based eater by filling up on these vegan foods [4
Seaweed (134 mg per ounce)
Chlorella (100 mg per 3 grams)
Brussels sprouts (135 mg per ½ cup cooked)
Flaxseeds (2.4 g per tablespoon)
Walnuts (2.6 g per ounce)
Chia seeds (5 g per ounce)
Hemp seeds (1 g per tablespoon)
Beans (100 mg per ½ cup)
Edamame (280 mg per ½ cup)
Vegan “fish oil” supplements
Introducing Iwi, Elo’s new vegan omega-3 product
Another great way to get your Omega-3s is with Iwi
, Elo’s new, ground-breaking vegan omega-3 product. Derived from Nannochloropsis microalgae, it’s rich in EPA and has been shown to reduce total cholesterol without decreasing HDL (good cholesterol).
Here are some other benefits of Iwi:
The omega-3 fats found in Iwi have been shown to be 50% more bioavailable than those in fish or krill because they’re bound to glycoproteins and phospholipids [12
Dosage. Each Iwi capsule contains 250 mg of omega-3s and 150 mg of EPA.
Sustainability. Since Iwi is farmed on land, it doesn’t disrupt fragile aquatic ecosystems like other marine omega-3 products. Instead, it’s farmed in saltwater in New Mexico and Texas, meaning that 97% of water entering the system is reused.
Studies have found that
Iwi’s vegan omega-3 reduces VLDL (bad) cholesterol levels by 25% after 12 weeks of supplementation (1g/day) [13
Omega-3 fatty acids are essential to overall health, as they play important roles in hormone production, inflammation, brain health, fetal development, and blood clotting. While you can consume them through both animal- and plant-based sources, you may find it challenging to meet your needs on a vegan diet. However, this feat isn’t impossible, as you can add certain omega-3 rich foods (such as walnuts, chia seeds, seaweed, and algae) to your diet and include Iwi supplements to fill in the gaps. As such, it’s possible for you to meet your omega-3 needs sans seafood.
