When most people think of omega-3s, fish oil is often the first thing that comes to mind. But there’s another, more plant-aligned source gaining attention: algal oil. Derived from marine algae, algal oil offers a fascinating alternative for those interested in exploring a non-animal-based option for omega-3s.

What Exactly Is Algal Oil?

Algal oil is a lipid extract obtained from algae—specifically, from a strain of microalgae known as Schizochytrium sp. This microscopic organism is naturally found in marine environments and has the unique ability to produce high amounts of long-chain omega-3 fatty acids, including DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid).

Unlike macroalgae (seaweed), which are visible and often used in culinary applications, microalgae like Schizochytrium are single-celled organisms. These marine microorganisms serve as a foundational food source in aquatic ecosystems, often consumed by krill and small fish, which then pass along omega-3s up the food chain.

Extracting Algal Oil 

The process begins by cultivating Schizochytrium sp. Once the algae reach a desired density, the next step is harvesting. The biomass is collected, dried, and prepared for lipid extraction where the oil is carefully extracted from the algae. This results in a golden, nutrient-dense oil that is naturally rich in omega-3 fatty acids.

A Plant-Based Option from the Sea

One of the most compelling features of algal oil is its marine origin without involving fish or other animal sources. Algal oil offers a way to trace omega-3s directly to their original source—algae—rather than obtaining them second-hand from fish who consume algae in their diet.

This characteristic makes algal oil a desirable option for those who follow a plant-based lifestyle or prefer supplements not derived from marine animals. It also provides an option for individuals avoiding common allergens like shellfish.

The Composition of Algal Oil

An algal oil supplement includes a defined amount of omega-3 fatty acids. These may include DHA, EPA, and occasionally other supporting fatty acids, all of which occur naturally within the algal lipid profile.

It's important to note that not all the oil is composed of omega-3s. The remaining portion consists of supporting fatty acids and lipids that serve as carriers. These components are naturally part of the microalgae’s cell structure and are preserved during the extraction process.

In Summary

Algal oil offers a glimpse into the untapped potential of the marine plant world. Cultivated from Schizochytrium sp., this microalgae-based oil delivers a clean and traceable source of omega-3s that originates from the ocean’s very foundation. With its careful cultivation, extraction, and composition, algal oil represents a unique way to reconnect with the sea—one drop at a time.

As always, talk to your doctor before taking any supplements. Get professional advice if you think you might need any algal oil supplement or are already taking one to ensure you’re not exceeding the amounts you may need.
