stomach and intestine.

How it works

AstaReal® Astaxanthin supports mucosal immunity, which functions as a first  line of defense against inhaled and ingested pathogens. AstaReal® Astaxanthin supported immunity even when salivary antibody (sIgA) levels were challenged by adverse conditions such as mental exercise, mild physical stress, or athletic training regimen.

The benefits of AstaReal extend from oral immune exclusion through to the gut where natural astaxanthin helps support a healthy microbiome, and may increase levels of the good gut bacteria called Akkermansia. Finally, AstaReal’s outstanding antioxidant and anti-inflammatory properties support immune function throughout the body, promoting overall wellness.
