Why Seaweed?


Seaweed is the unrivalled multi-supplement, which delivers a blend of natural nutrients that can be deficient from soils and feed. Seaweed contains over 60 minerals, and trace elements, vitamins, carbohydrates, amino acids, essential fatty acids, natural bioactive hormones, growth factors and anti-oxidants.

The ocean contains a constant reservoir of micronutrients that are absorbed by seaweed and stored within the algae in a protected, colloidal state. This colloidal structure means that > 98% of all the micronutrients are absorbed in the animal allowing them to fulfil their diverse range of functions.
