The Active Ingredient Is: Red Marine Algae Extract (Gigartina skottsbergii)

Red marine algae extract is a seaweed-derived ingredient containing polysaccharides, notably carrageenans, that contribute to normal immune function and cellular defence mechanisms.

This form is sourced from red seaweed and provides natural polysaccharide compounds that participate in the body’s frontline defence and antioxidant activity.

What Does Red Marine Algae Do?

Red marine algae supports immune health by helping modulate the body’s natural responses and by reducing the binding of unfriendly proteins to cell surfaces. It also provides antioxidant activity that helps protect cells from oxidative stress and can be associated with joint mobility support in some contexts.

These effects align with traditional and scientific observations of carrageenan-containing seaweeds contributing to immune modulation and antioxidant activity, as recognised in EFSA-aligned summaries of nutrient function.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
