For decades, fish oil has been the go-to source of omega-3 fatty acids.
One of the biggest misconceptions is that fish are the original source of omega-3s. When in reality, it’s actually algae that contain the original source of omegas.
The omega-3 fatty acids DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) originate in marine microalgae and phytoplankton.
Fish accumulate these beneficial fats by eating algae directly or by consuming smaller marine organisms that have already done so.
This means fish are simply a vehicle for omega-3s rather than the producer. Learn more on this process here.
The Same Essential Omega-3s
Whether they come from fish oil or algae oil, DHA and EPA are chemically identical. These are the omega-3 fatty acids that have been extensively researched for their role in supporting brain function, heart health, eye health, pregnancy and healthy ageing.
Clinical research has shown that algae-derived DHA and EPA are well absorbed by the body and are an effective way to increase omega-3 levels.
Rather than obtaining these nutrients second-hand through fish, algae oil provides them directly from their natural source.
A Cleaner Source of Omegas
Because algae are grown in controlled cultivation systems, algae oil offers a highly controlled and traceable source of omega-3s. Fish can accumulate environmental contaminants from the marine food chain over time, which is why quality fish oil manufacturers use extensive purification processes.
Algae oil bypasses this food chain entirely, providing a direct source of omega-3s from cultivated marine microalgae.
High-quality algae oils are produced under carefully controlled conditions, resulting in a consistently pure and reliable product.

Better for Our Oceans
The world's demand for omega-3 supplements continues to grow, placing increasing pressure on marine ecosystems.
Choosing algae oil helps reduce reliance on wild-caught fish used for omega-3 production. Because microalgae can be used sustainably, they provide a renewable source of DHA and EPA without depending on fish stocks.
As consumers become more conscious of their environmental impact, choosing the original source of marine omega-3s offers a practical way to support both yourself and the ocean.
Ideal for Plant-Based Lifestyles
Algae oil is naturally vegan and vegetarian-friendly. Many people following plant-based diets struggle to obtain enough DHA and EPA because common plant sources such as flaxseed, chia seeds and walnuts contain ALA (alpha-linolenic acid).
While ALA is an omega-3 fat, the body's conversion of ALA into DHA and EPA is relatively limited.
Algae oil provides DHA and EPA directly, making it an excellent option if you want a plant-based source of these important nutrients.
Why Source Matters
When choosing an omega-3 supplement, it is worth looking beyond the words "fish oil" or "omega-3" on the label.
Consider where the omega-3s come from, how they're produced and whether the product aligns with your values around sustainability and quality. Learn more in our article ‘How to Choose a Good Omega-3 Supplement: 5 Things to Look For’.
At Phytality, we believe the future of omega-3 nutrition starts where nature intended, with marine microalgae. Our algae-derived omega-3 delivers both DHA and EPA directly from the original source, offering a clean, sustainable and ocean-friendly alternative to traditional fish oil.
The science is simple, fish don't make omega-3s. Algae do. By going straight to the source, you can enjoy the same essential marine omega-3s while supporting a more sustainable future for our oceans.
