Algae Oil vs. Fish Oil: Omega 3 DHA Sources Compared

Blog Omega 3

Omega-3 fatty acids, notably eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been championed for their extensive health benefits. While fish oil has historically been the primary source of these essential nutrients, an enlightening fact is that fish themselves do not produce omega-3s. Instead, they accumulate these fatty acids by consuming algae. Thus, with sustainability and purity concerns on the rise, algae oil emerges as a direct and promising source of DHA. 

Omega 3 DHA: The Importance and Its True Source

DHA is a long-chain omega-3 fatty acid integral to the proper functioning and structure of our brain and eyes. While fish are rich in this compound, it's important to understand they obtain it from their diet, primarily algae. This realisation positions algae, not fish, as the foundational source of omega 3 DHA. It's known to be particularly important during pregnancy and early childhood for neural and vision development. Additionally, numerous studies have indicated that adequate intake of DHA might help reduce the risk of certain chronic diseases, such as heart disease.

Fish Oil: The Traditional Source


  • Rich in EPA and DHA: Fish oil not only contains DHA but also EPA, another essential omega-3 fatty acid with its unique health benefits, including potential anti-inflammatory effects.
  • Long-standing research: Numerous studies spanning decades back up the health benefits of fish oil supplements.


  • Environmental and Ecological Concerns: The demand for fish-derived omega-3s contributes to overfishing, which not only depletes fish populations but also disrupts and damages marine ecosystems. There's also the issue of bycatch—unintended marine life that gets caught in the process. This can have cascading effects on the food chain and marine biodiversity, exacerbating the global overfishing crisis and contributing to the decline of critical marine habitats.
  • Pollutants: Many fish, particularly large predatory species, accumulate toxins such as mercury. These toxins can make their way into fish oil supplements, though many high-quality brands undergo processes to remove them.
  • Taste and odour: The fishy aftertaste can be unpleasant for some consumers.

Algae Oil: The Plant-Based Alternative


  • Sustainable: Algae can be cultivated sustainably in controlled environments, reducing the environmental impact.
  • Purity: Grown in controlled environments, algae are less likely to contain pollutants like heavy metals.
  • Vegan and Vegetarian-friendly: A boon for those avoiding animal products.
  • Straight to the Source: By using algae oil, consumers are accessing the origin of fish-derived omega 3s, ensuring a more direct nutrient source.


  • Primarily DHA: While algae oil is rich in DHA, it generally contains minimal to no EPA. Some modern formulations, however, are working to address this imbalance.
  • Cost: The cultivation of algae for oil can be more expensive, though costs may decrease as the technology advances.

The Verdict

In the journey of understanding the primary sources of Omega-3 DHA, one thing becomes crystal clear: algae stand as nature's original and direct source of this essential fatty acid. This knowledge repositions our approach towards omega 3 supplementation.

Our plant based algae-derived liquid omega-3 stands out in this new era of nutritional supplementation. Not only is it rooted in the primary, sustainable source of DHA, but it also offers an impressive potency. Without the use of any carrier oils, every 1ml delivers a potent serving of 530 mg of plant based DHA. This ensures that individuals receive a substantial amount of this crucial nutrient in a single, efficient serving, without any fishy aftertaste or environmental drawbacks associated with fish-derived products.

In essence, by opting for a vegan, algae-based omega 3, consumers are embracing a future-forward, more eco-friendly, and direct approach to health supplementation. It represents a pure, potent, and environmentally responsible choice, aligning with modern preferences and ethical considerations. As we move forward in the realm of health and nutrition, returning to nature's original sources, like algae, seems not only logical but also imperative for the well-being of both individuals and our planet.
