Why is algae oil safe for human consumption?

Several versions of algae oil have GRAS (generally recognized as safe) status under the FDA framework and toxicology studies have demonstrated their safety.

This oil was formerly bottled and sold to consumers under the Thrive brand where it was distributed widely to grocery store locations (including Walmart, Sprouts, and Safeway) in the United States. From its launch in 2015 through 2018, Thrive® Culinary Algae Oil was sold to consumers at thousands of retail locations and the brand had a consistent five star rating on Amazon.

For more than 20 years, microalgae have played a crucial role in the production of oils concentrated in Omega-3 fatty acids like DHA (Docosahexanoic acid) and EPA (Eicosapentanoic acid), which are commonly added to infant formula and dietary supplements. Leveraging microalgae for Omega-3 production is widely acknowledged as a way to meet nutritional needs in these applications.¹³
