The Active Ingredient Is: Spirulina (Arthrospira platensis)

Spirulina, a blue-green microalgae, is a concentrated whole-food source used as a supplement ingredient for its nutrient-rich profile.

This form is derived from Arthrospira platensis and is provided as a tablet supplement containing the spirulina organism as the active ingredient.

What Does Spirulina Do?

Spirulina participates in antioxidant pathways via phycocyanin and provides unsaturated fatty acids that contribute to normal cardiovascular function, while zinc supports immune function in line with EFSA guidance. This combination helps support overall antioxidant capacity and immune health in line with normal physiological roles.

This information aligns with general EFSA and NHS understandings of how nutrients support normal body functions.
