                      Frequently Asked Questions About Kelp Supplements

                       

                      Q: What Is Kelp?

                      Kelp is a type of large brown algae that makes up one of thirty different Laminariales.

                      It’s more commonly referred to as seaweed but does vary in color, flavor, and nutrient profile compared to other seaweeds in the Laminariales family.

                      Kelp is harvested from shallow, nutrient-rich coastal waters and coastlines worldwide and contains many health benefits due to its strong nutrient profile.

                      It’s generally considered umami, a rich, savory flavor, and can be consumed raw, cooked, or in supplements.

                       

                      Q: What Are The Benefits of Kelp?

                      Kelp also contains a mineral called Vanadium, which has been shown to regulate blood sugar levels and help people with type 2 diabetes.

                      Recent studies suggest that kelp may also slow the spread of colon and breast cancers and lung and prostate cancer.

                      However, these studies in still ongoing, and it is yet to be proven that keep can reduce cancer in people.

                      Scientists are also investigating the benefit of fucoxanthin, a substance in brown algae that is believed to help with weight loss.

                      Q: Does Kelp Have Any Side Effects?

                      Like most things in life, kelp is best consumed in moderation.

                      Although deemed safe to consume, too much kelp may overstimulate your thyroid gland due to high levels of iodine. It would, therefore, not be suited for people who suffer from hyperthyroidism as it has been linked to too much kelp intake.

                      Also, as kelp is known to absorb nutrients from the water it grows in, it may contain harmful metals like aluminum and lead.

                      Therefore, it’s essential to do your research when choosing between different kelp supplements and make sure they’re certified for purity.

                       

                      Q: How Do I Take Kelp?

                      Depending on which one you have, as a general rule of thumb, you should always start by following the manufactures serving guidelines and adjusting your dose accordingly as you progress.

                      The average recommended daily intake of iodine for adults is 150 mcg.

                      The FDA’s guidelines state a recommended maximum daily intake of 225 micrograms for adults and children more than 4 years of age.

                      If you suffer from thyroid problems, consulting with your doctor first is highly recommended.
