Main Facts about Kelp

Kelp (Laminariales Phaeophyceae)
Kelps are large annual seaweeds, they grow from a spore to maturity within a single year. It grows in underwater "forests" (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 23 to 5 million years ago. Kelp is found mainly in kelp forests within shallow bodies of saltwater and can grow up to half a meter a day, ultimately reaching heights of 30 to 80 meters. The kelps have in common a capacity for some of the most remarkable growth rates in the plant kingdom.

Using Kelp

Kelp is well known as an excellent source of most of the important minerals. Kelp contains many vitamins, especially B vitamins, which are essential for cellular metabolism and providing your body with energy. It also contains vitamins C and E, which are both strong antioxidants and promote blood vessel health. Minerals, such as calcium, boron and magnesium are plentiful in kelp; they are necessary for strong bones and normal muscle function. Kelp, like other seaweeds, is rich in sodium alginate, which is an element effective at protecting the body from radiation and removing it. Kelp is also a rich source of iodine, which is a crucial nutrient for the thyroid. Consuming iodine from plants like kelp also helps reduce the effects of radiation exposure.


Although some iodine is essential for thyroid function, ingesting too much of it can negatively affect thyroid function, causing hypo- or hyper-thyroidism. Kelp might also contain arsenic, and consuming large amounts of kelp supplements might lead to arsenic poisoning.
