1) Kelp Quick Facts

Kelp is a natural source of Iodine. The formula is claimed to have no added yeast, lactose, gluten, sugar, artificial flavors, sweeteners, colors, dairy products, or animal-derived products.

Kelp is a type of seaweed and has been used for more than a century in the treatment of thyroid problems. The plant has high iodine content, but also features numerous minerals, such as Potassium, Iron and Calcium and vitamins including B1, B2 and B12.

Sever Iodine deficiencies can lead to hypothyroidism, while less severe deficiencies may increase the risk for brain disorders and severe goiter (thyroid enlargement), and cause problems in movement, speech and hearing. While synthetic iodine is largely spread today, kelp remains a good source of dietary iodine, still successfully used in thyroid treatments.

Scientific research on the benefits of Kelp is limited; however, the plant enjoys great popularity. Kelp is also recognized for other uses including prevention of estrogen-related cancers (ovarian and endometrial cancer), cholesterol reduction, infection prevention, and protection from toxic heavy metals exposure such as Cesium, Barium and Cadmium.

Nutrition Facts

2) Kelp Nutrition Facts

Kelp includes the following ingredients: Fucus vesiculosus (Kelp) extract equivalent to dry blade 1000mg, containing Iodine 240mcg.

3) Does Kelp Work and it is Safe?

Kelp 1000mg contains Fucus vesiculosus extract as it was designed to be a natural source of Iodine.

Maintaining adequate amounts of Iodine inside the body is essential for the proper functioning of the thyroid gland. Iodine is a vital component of thyroxine, the hormone that regulates the production of energy, maintains the body temperature, respiration and muscle tone. It also promotes healthy skin, hair, and nails. Since kelp is a natural source of iodine, it is absorbed by your body more slowly and safely than chemical iodine is. This substance is also absorbed naturally from foods such as iodized salt, marine fish, algae, seafood, etc.

The thyroid gland can cause turmoil inside the body due to deficiency or excess Iodine. When one is suffering from Iodine deficiency, his thyroid gland expands very much creating a swelling that looks like a goiter. Other symptoms include weight gain, decreased libido, palpitations, low body temperature, or behavior disorders. On the other hand, excess iodine can lead to tremors of the extremities, tachycardia, and flushing.

The manufacturer recommends taking one tablet daily with food, or as directed by a healthcare professional. One should always be careful when supplementing with iodine as it can cause allergies.

My doctor recommended me Kelp to compensate an old Iodine deficiency. I prefer natural supplements to synthetic ones, so this is great for me. My nails are stronger, my energy is up and these are only a couple of benefits of Kelp!
