Let’s be honest—most people still think about nutrition in terms of protein, carbs, or calories. Fat is often treated like the nutrient we should fear—or at best, something people don’t think much about at all. Thanks, macro-counting culture.
But the reality is that certain fats—especially omega-3s—aren’t just “nice to have.” They’re foundational.
Omega-3 fats play critical structural and functional roles throughout the body, supporting everything from cardiovascular and brain health to exercise recovery, healthy aging, and overall inflammatory balance. Simply put, you need them.
When omega-3s do come up, most people immediately think of fish. Which leads to one of the most common questions I hear:
How are you supposed to get enough omega-3s—especially EPA and DHA—if you don’t eat fish? Or if you don't like anything fishy-like.
Here’s where things get interesting.
Omega-3 isn’t a single nutrient. It’s a family of fatty acids, and each type plays a different role in the body. The two most talked-about forms—particularly when it comes to cardiovascular health, brain function, and recovery—are EPA and DHA (I break down the different types of omega-3s a bit further below).
But what many people don’t realize is that while fish and seafood are familiar sources of EPA and DHA, they don’t actually produce these fats.
They get them from algae.
In other words, algae is the original source of these long-chain omega-3 fatty acids. Who knew?!
So no, you don’t need to rely on fish to get EPA and DHA. You can go directly to the source.
And that’s exactly where algae oil comes in!
My Top Vegan Omega-3 Supplement (Algae Oil for EPA & DHA)
So what exactly is algae oil—and why would you use it instead of fish oil?
Algae oil is a plant-based source of omega-3s—specifically EPA and DHA—derived directly from microalgae, which is actually where these fatty acids originate in the first place.
When it comes to getting EPA and DHA in a way that's plant-based, simple, and completely non-fishy, this is one of the few supplements I consistently come back to! The one I personally use is Nature's Way Plant-Based Omega-3.
While I don't rely on supplements as the foundation of health—that always comes back to whole foods rich in phytonutrients, fiber and an overall anti-inflammatory diet pattern—this is one of the few that actually makes sense to support overall health.
Here's why: while the body can technically convert plant-based omega-3s (ALA) into EPA and DHA, that conversion is limited and varies from person to person. Rather than leaving that up to chance, I prefer to get EPA and DHA directly. This product provides a meaningful dose in a small, manageable amount, making it easy to incorporate into a daily routine.
Even if you're not fully plant-based, this can still be a great option. It provides EPA and DHA without the fishy taste or burps—and without relying on the marine food chain, where environmental contaminants such as mercury, PCBs, and dioxins can accumulate in certain fish species.
Why I Continue To Use It
• Provides 1000 mg EPA + DHA per teaspoon
• Delivers EPA and DHA directly from algal oil (the original source)
• Completely plant-based and vegan
• No fishy taste, burps, or lingering aftertaste
• Light, pleasant flavor
• Liquid format that's simple to take and easy to digest
At the end of the day, there are several quality algae oil supplements on the market, and this is simply the one that has worked best for me. It provides a meaningful dose of EPA and DHA, fits seamlessly into a plant-based lifestyle, sits well on my stomach, and is the one I continue to use day after day.
Understanding ALA, EPA, and DHA
This is where things get a little more nuanced—and where much of the confusion around omega-3s tends to come from.
Omega-3 isn't a single nutrient. It's a family of fatty acids, each with distinct functions in the body. The three primary forms are ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid).
All three are important—but they're not interchangeable.
ALA (Alpha-Linolenic Acid)
If you follow a plant-forward diet, most of your omega-3 intake will come from ALA. Foods such as flaxseed, chia seeds, hemp seeds, and walnuts are among the richest plant sources.
ALA is an essential omega-3 fatty acid, meaning the body cannot produce it on its own and must obtain it through food. Higher ALA intake has been associated with cardiovascular health, healthy aging, and healthy inflammatory balance, making it an important component of an anti-inflammatory nutrition approach.
ALA is most often associated with:
• Cardiovascular health
• Healthy aging
• Healthy inflammatory pathways
• Cellular health
This is one of the reasons I'm such a strong advocate for regularly including nuts and seeds in the diet. These foods provide far more than omega-3s alone—they also deliver fiber, antioxidants, phytonutrients, minerals, and other beneficial compounds that support overall health.
That's why you'll see them featured repeatedly throughout my recipes, smoothies, and Vegan Detox approach.
However, ALA is not the same thing as EPA and DHA.
The body can convert ALA into EPA and DHA, but the conversion process is relatively limited and varies considerably between individuals.
EPA (Eicosapentaenoic Acid)
EPA is a long-chain omega-3 fatty acid best known for its role in supporting cardiovascular health and healthy inflammatory balance. Because of these functions, EPA is often valued by active individuals and those following an anti-inflammatory nutrition approach.
EPA is most often associated with:
• Cardiovascular health
• Healthy inflammatory pathways
• Exercise recovery
• Joint health and mobility
DHA (Docosahexaenoic Acid)
DHA is a major structural component of the brain and retina and is found throughout the nervous system. Because of its important role in these tissues, it is considered an important omega-3 fatty acid for cognitive health, eye health, and overall neurological function.
DHA is highly concentrated in:
• The brain
• The retina of the eye
• The nervous system
The Bottom Line
When it comes to omega-3s, ALA, EPA, and DHA each serve unique functions in the body and are all important for overall health.
Whole-food sources of ALA, such as flaxseed, chia seeds, hemp seeds, and walnuts, remain a foundational part of an anti-inflammatory nutrition approach because they provide omega-3s alongside fiber, antioxidants, phytonutrients, and other beneficial compounds.
At the same time, obtaining EPA and DHA directly is a practical way to support overall omega-3 intake without relying entirely on the body's conversion of ALA.
That's exactly why I use algae oil.
It allows me to prioritize nutrient-dense plant foods while also obtaining EPA and DHA directly from the original source—without relying on fish or the marine food chain.
The Plant-Based Fat Sources I Prioritize
While I personally supplement with algae oil to obtain EPA and DHA directly, whole-food fat sources remain a foundational part of my approach.
That's because foods like hemp seeds, chia seeds, ground flaxseed, pumpkin seeds, walnuts, pistachios, almonds, and avocado provide much more than healthy fats alone. They also deliver fiber, antioxidants, phytonutrients, vitamins, minerals, and other beneficial plant compounds that support overall health.
In fact, dietary patterns rich in nuts, seeds, and other whole plant foods have been associated with benefits for:
• Cardiovascular health
• Healthy inflammatory pathways
• Blood sugar regulation
• Satiety and weight management
• Healthy aging (both inside and out - hello, good skin!)
• Long-term health and chronic disease prevention
One of my personal favorites is hemp seeds. In addition to providing ALA omega-3 fats, hemp seeds also deliver plant protein, magnesium, iron, zinc, and other nutrients that support recovery, muscle health, skin health, and overall vitality.
This is exactly why you'll see these foods featured so heavily throughout my recipes, smoothie formulas, and nutrition programs. One of the simplest ways I've found to consistently increase the nutritional value and anti-inflammatory potential of the diet is by incorporating them into a daily smoothie.
Including adequate amounts of nutrient-dense fats can help support satiety, stable energy levels, nutrient absorption, and a more sustainable approach to healthy eating.
That's why I view algae oil as a complement to—not a replacement for—a strong nutritional foundation built on whole, nutrient-dense plant foods.
If you're looking for a simple place to start, these are many of the same foods and smoothie principles I teach inside the 7-Day Green Smoothie Challenge and Vegan Detox: 21-Day Anti-Inflammatory Diet jumpstart program.
Final Takeaway
If there's one thing I hope you take away from this article, it's this:
Healthy fats matter.
Consuming a wide variety of nutrient-dense plant foods—including nuts, seeds, legumes, fruits, vegetables, and other fiber-rich whole foods—is one of the most powerful things you can do to support cardiovascular health, healthy inflammatory pathways, healthy aging, and long-term wellness.
When it comes to omega-3s specifically, foods like hemp seeds, chia seeds, flaxseed, walnuts, and other plant foods provide ALA—an essential omega-3 fatty acid that the body cannot produce on its own and must obtain through the diet.
At the same time, fish aren't the only way to obtain EPA and DHA.
Because fish get these omega-3s from algae, you can go directly to the original source.
For me, that means prioritizing both: a diet rich in whole plant foods and a direct source of EPA and DHA through algae oil.
The supplement featured in this article is simply the one I personally use because it provides a meaningful dose of EPA and DHA, fits seamlessly into my plant-based lifestyle, sits well on my stomach, and is easy to take consistently.
And because so many people ask me which omega-3 supplement I use, now you have my answer.
Most importantly, remember this:
Fat is not the enemy.
The right fats provide some of the most important nutrients your body needs to support energy, recovery, cellular health, and long-term well-being.
Choose them wisely, consume them consistently, and let your daily habits do the heavy lifting.
