How it is made

From marine microalgae to Omega-3 rich algal oil

At our state-of-the-art facility in Blair, Nebraska, in the US, Veramaris uses natural microalgae, fermenting them with precision to yield a nutrient-rich oil full of essential Omega-3 EPA & DHA fatty acids. The zero-waste process includes cultivation, harvesting, and an efficient extraction method that not only yields nutrient-rich oil but also generates Veraferm, a valuable by-product for cattle feed.

By transforming these microalgae into precious algal oil, we set a new industry standard and contribute to the health of animals and humans globally, while reinforcing our commitment to sustainability.

Producing Omega-3 through waste-free fermentation

Our production site is located in Blair, Nebraska – right in the middle of the United States of America.
It is one of the biggest biotech production facilities worldwide.


The Veramaris process has been refined to the point where it requires only two main materials: sugar and marine algae. This is a result of 35 years of intensive research, including the study of some 6,500 different microalgae, and a sophisticated proprietary biotechnology. Any plain sugar can be used as a substrate, but since our facility is located in Nebraska we currently use locally-produced corn sugar that comes from 16 local counties. The process is also supported by some other basic ingredients, including salts, nutrients, acids, vitamins and water.


The raw materials are blended and this substrate is then transferred into a laboratory fermenter containing the precise balance of nutrients and vitamins necessary for the microalgae cells to flourish. Our algae are unique heterotrophic organisms that thrive without sunlight. The cells then move through progressively larger fermentation vessels, allowing the microalgae to accumulate high levels of Omega-3 EPA & DHA fatty acids, setting the stage for the subsequent harvesting and extraction of the algal oil.


When the algae cells are saturated with oil, they progress to the harvesting phase, where the cell walls are carefully breached. Using an enzymatic process, the oil is harvested and the co-product is also separated. This meticulous process is designed to be waste-free, reflecting Veramaris dedication to environmental responsibility.


During the harvesting phase, the valuable by-product, Veraferm, is isolated. Veraferm is the residual material left after the algal oil is extracted and consists of protein, coming from the microbial cell walls, and energy, from the remaining oil. This serves as a sustainable cattle feed in local farms, supporting the circularity of production.

Algal Oil

The result is Veramaris algal oil. With a concentration of 65% EPA & DHA, Veramaris algal oil delivers a potency that is up to five times that of traditional fish oil sources. This not only reduces the reliance on wild fish stocks, but also provides a consistent and scalable supply of these nutrients.

The algal oil product is certified by the Aquaculture Stewardship Council and the Marine Stewardship Council – underscoring our commitment to sustainable business practices.
