What Is Euglena? A Complete Guide to the Okinawan Superfood

A nutrient-dense microorganism with a wellness story

Although Euglena has been used in Japan for decades, it is only recently gaining global attention as interest grows in healthy aging, gut health, and whole-food nutrition. Rich in naturally occurring nutrients and cultivated in Okinawa, Japan, Euglena represents a new generation of multifunctional superfoods.

What Is Euglena?

Euglena (Euglena gracilis) is a unique freshwater microalga that naturally contains 59 nutrients, including vitamins, minerals, amino acids, unsaturated fatty acids, and Paramylon—a naturally occurring beta-1,3-glucan found only in Euglena.

Unlike many other algae, Euglena has no rigid cell wall, making its nutrients more readily accessible and highly digestible.
