<i>Euglena gracilis</i> Suppresses Cold Symptoms in Healthy Individuals: A Double-Blind, Randomized, Placebo-Controlled Trial.

ABSTRACT: The immune system functions to eliminate pathogens, such as viruses, and regulate physiological responses and pathways. General immunity is affected by various factors, including fatigue, stress, and aging. A weakened immune system reduces the ability of the body to eliminate pathogens, thereby increasing the risk of infections, including the common cold. Euglena gracilis is a microalga rich in various nutrients, including β-1,3-glucan paramylon, which aids in maintaining and regulating immune function. In the present study, we aimed to investigate the effects of E. gracilis administration on cold symptoms in healthy individuals. Euglena gracilis was administered orally in capsule form (once daily, in the morning) continuously for 8 weeks to healthy adult Japanese men
