Giant Kelp

Also known as Macrocystis pyrifera

Giant kelp is a nutrient dense superfood. Not only does it have a particularly high iodine content, giant kelp is rich in vitamins, minerals, antioxidants and alginates (a form of dietary fibre). Macrocystis pyrifera is the largest of the seaweeds, growing up to half a metre a day in kelp forests in the Pacific Ocean.
