Benefits of Sea Kelp

Updated July 19, 2017

Kelp is a type of large, brown seaweed which grows in shallow and nutrient-rich waters. It is a natural source of essential vitamins and minerals, and its medicinal properties have been valued for centuries. Today, sea kelp is available as a dietary supplement and can be purchased in the form of capsules, tablets, liquids or powders.


Sea kelp contains high levels of iodine, which promotes a healthy thyroid and therefore helps to regulate metabolism.

Immune System

Because it is so rich in nutrients, sea kelp provides a boost to the immune system and can even help to ease symptoms of stress in the body.


Sea kelp is exceptionally high in calcium, even more so than milk. A daily intake of kelp can help to strengthen bones and prevent osteoporosis.


Sea kelp contains alkali, which is an ionic salt. Alkali balances the body's acidity levels, preventing acid indigestion and stomach ulcers.


Omega-3 essential fatty acids are found in sea kelp, and these are important for maintaining a healthy circulatory system. Sea kelp supplements can aid in protecting the heart by keeping the arteries free of plaque.
