Omega-3 fatty acids are essential to cardiovascular, brain and cellular health, yet many Americans—particularly those following plant-based or vegetarian diets—do not get enough of the most critical forms: EPA and DHA. Vegan omega oils derived from algae offer a clean, sustainable and effective solution to bridge this nutritional gap.

Omega-3s are considered essential fats because the body cannot produce them on its own. While plant foods such as flaxseed, chia seeds, walnuts and leafy greens provide omega-3s in the form of ALA, the body must convert ALA into EPA and DHA to support heart and brain tissues. Unfortunately, this conversion is highly inefficient—often less than 5 percent for EPA and under 1 percent for DHA—and may be further reduced by stress, aging, genetics and high intake of omega-6 fats common in modern diets.

EPA and DHA play a vital role in keeping cell membranes flexible, supporting healthy blood vessel function, regulating inflammation and maintaining stable heart rhythms. Without adequate levels, inflammation may linger, vascular function may decline and cardiovascular resilience may be compromised—even when cholesterol and blood pressure appear normal.

A useful tool for assessing omega-3 status is the Omega-3 Index, a blood test that measures EPA and DHA levels in red blood cell membranes. Unlike short-term dietary tracking, this test reflects long-term tissue levels. Research suggests an optimal Omega-3 Index falls between 8 and 12 percent, while levels below 4 percent are associated with increased cardiovascular and inflammatory risk. In the U.S., the average Omega-3 Index hovers just above 4 percent, highlighting a widespread need for improvement.

Traditionally, fish oil has been the primary supplemental source of EPA and DHA. However, algae-based omega oils provide these same nutrients directly from their original source. “Fish don’t actually make omega-3s,” explains Joakim Graff, founder of NORSAN. “They accumulate them from algae. That’s why we believe a high-quality algae oil should be left as close to its natural form as possible.” 

Algae-derived omega oils offer several advantages. They are fully vegan, environmentally responsible and produced in controlled settings, which reduces the risk of ocean contaminants. They also eliminate the fishy taste or aftertaste that can deter consistent use—an important factor, as omega-3 supplementation is most effective when taken daily.

Experts recommend a personalized, evidence-based approach: test omega-3 levels, supplement as needed and retest to ensure tissues are receiving adequate EPA and DHA. For individuals with low Omega-3 Index scores, intake of 1,500 to 2,000 milligrams of combined EPA and DHA daily is commonly suggested, ideally taken with meals containing healthy fats to support absorption. 

At the Central Florida Vegan Festival, Matthias Haberzettl, representative from NORSAN, emphasized that improving omega-3 intake benefits all diets, not just plant-based ones. “Behind everything we do at NORSAN are two central ideas,” he said, “To pass on knowledge about the effects of omega-3 fatty acids and to improve supply by offering high-quality omega-3 products.” 

For those seeking a plant-powered, ethical way to support heart and brain health while honoring environmental values, algae-based vegan omega oil offers a simple, effective and sustainable option—nourishing the body from the inside out.

NORSAN is a science-driven company dedicated to improving global omega-3 intake through high-quality oils in their most natural form and responsibly sourced from fish or algae.
