Tangle kelp

Laminaria hyperborea is primarily valued for its high-quality alginate, but its side streams contain laminarin and phlorotannins with potential antioxidant and metabolic benefits. Preclinical studies suggest its extracts may support gut health and reduce methane emissions in ruminants. Human clinical evidence for direct health benefits remains limited.
