Kelp Benefits

Kelp is seaweed found off the coast of Hawaii, Iceland and Pacific North America. It grows in long, trailing fronds that can reach up to 200 feet in length. For over a century kelp was used as a treatment for thyroid problems due to its high iodine content. It remains an excellent source of dietary iodine and is also used in treating radiation and heavy metal exposure, heart disease and preventing infections.

Vitamins and Minerals

In addition to iodine, kelp contains minerals including calcium, iron and potassium, and vitamins B1, B2, and B12. The use of kelp to treat thyroid problems has been largely superseded by synthetic medications, although it is still an effective way to incorporate iodine into the diet.

Heart Disease

The sodium alginate in kelp may also help to reduce cholesterol in the bloodstream. For those individuals who are not sensitive to salt, sodium alginate may also act to reduce high blood pressure.

Infection Prevention

Kelp may help to prevent infection from some types of viruses. Kelp may also be useful as an impromptu bandage. Constituents in kelp interfere with the growth of some bacteria and fungi and may help prevent infection, particularly for cuts and scrapes that may have been exposed to seawater. Try applying kelp to the wound until a better bandage can be obtained.

Radiation and Toxic Metals

Sodium alginate is used to prevent the absorption of radioactive elements. In particular, it protects against strontium-90 a by-product of nuclear power generation and weapons production. It may also protect the body from other toxic heavy metals including plutonium, cesium, barium and cadmium. Those working in or living around facilities that use radioactive materials may, at some point, be inadvertently exposed to these substances. Taken as a supplement, sodium alginate is used primarily as a treatment for recent exposures that occur from ingestion. It has been shown to absorb over 80 percent of ingested strontium-90.
