Kelp Supplements Guide

The seaweed known as kelp is perhaps best known for the prominent role it plays in traditional Japanese cuisine. People living in costal regions of the “Land of the Rising Sun” have been eating this savory seaweed for centuries, and many have touted its amazing health benefits over the years.

Nowadays, doctors in the West have become increasingly interested in the healing benefits of this humble seaweed. In this article, we’ll take a closer look at kelp’s many benefits and let you know all about what this super food can do for you.

What is Kelp?

As mentioned above, kelp is a kind of seaweed that generally grows in coastal regions. Perhaps the most famous areas of the world where kelp thrives include the coasts of Japan, Ireland, and the USA. Although the United Nations recently found that an astonishing 99 percent of the world’s seaweed is produced in Southeast Asia, a great deal of kelp has been produced on the California coast in recent years. Kelp can come in a wide variety of colors, including green, brown, and even red. In total, experts estimate that there are at least 30 varieties of kelp around the world.


The main side effects related to kelp usually have to do with taking in too much iodine. An overdose of iodine could lead to a condition known as hyperthyroidism, which is characterized by symptoms like weight loss, rapid heartbeat, and a fast metabolism. Anyone with diseases like hyperthyroidism or Grave’s disease is advised not to take kelp supplements without a doctor’s supervision.

Many people who take an excess of kelp report symptoms like diarrhea and heartburn. Since kelp has many laxative chemicals, these symptoms are to be expected, and sometimes they could actually be related to a healthy detox. Of course, always check with your doctor if your symptoms persist for numerous days. Also be sure to drink plenty of water to avoid dehydration.

You should let your doctor know how much kelp you are taking before undergoing any surgical procedures, since too much kelp in your system could cause you to bleed excessively during surgery.

Always speak with a medical professional or doctor before taking any supplements. Always read the product label for instructions and directions.

Taking Kelp

The most common way to take kelp, of course, is to eat it. Besides eating it in seaweed form, you could order products like kelp flakes or kelp noodles to incorporate into your weekly diet. There are also various kelp teas and tinctures available at many health food stores. A few popular Asian dishes that incorporate kelp include Miyeok-guk and Tsukudani.

People who don’t like the taste of kelp could take a kelp capsule on a regular basis. A majority of manufacturers make kelp capsules that are 600mg or fewer, so it’s very easy to track your daily intake of kelp. Under U.S. federal law, iodine levels in all kelp capsules must be no more than 225mcg. Anything higher than 225mcg is considered unsafe for the general populace.

Another interesting way to incorporate kelp into your life is to take either a kelp bath or make a kelp body wrap. Some nutritionists say you can really help the body absorb the nutrients in kelp by using this method.

What to Look for in a Good Kelp Supplement

The main thing to look for in a kelp supplement is whether or not the company added any bladderwrack to the product. Bladderwrack is another sea vegetable like kelp, however it is slightly toxic in high volumes. Some manufacturers try to pass off their product as kelp but actually use bladderwrack or some other form of seaweed as the main ingredient. One brand doctors say to avoid completely is called Maine Sea Coast Kelp.

You should also check where in the world your kelp is coming from. Kelp coming from oceans without pollution is, of course, ideal. The pure ocean waters can actually add minerals and nutrients to your kelp product that will enhance its overall healing effect.
