The iodine in dry kelp varies from 70000 to 100000 microgramme, after soaking, washing and process, there is around 95% of iodine lost from the kelp. The daily dosage varies according to ages,

150mcg for adults

200mcg for pregnants and during nursing

50mcg for babies under 3years old

90mcg for children between 4 to 10 years old

120mcg for children between 11 and 13 years old

Pure natural seaweed iodine is extracted from kelp by physical methods, besides the organic iodine, other kelp nutrients are retained, such as algin gum, calcium, iron, vitamins, it is a more comprehensive nutrition of daily health food, with the following characteristics:

1. seaweed iodine contains about 20% of organic iodine (tyrosine iodine), can be absorbed evenly by the human body. The organic iodine is easier to be stored in our body so that it can be replenished in time when the body needs it. Compared with inorganic iodine, it is not affected by the restriction of iodine absorption due to insufficient protein intake. The inorganic iodine in seaweed can be quickly absorbed and utilized by the human body, but the excess inorganic iodine will be excreted, so excessive intake of the iodine will not happen. Therefore, pure natural seaweed iodine has the dual advantages of organic iodine and inorganic iodine, and is an ideal iodine nutrient for human body, which can effectively reduce the incidence of hyperthyroidism.

2. Seaweed iodine is also rich in polysaccharides sulphate, fucoate polysaccharides, alginic acid, algin gum, unsaturated fatty acids and other substances, which can improve human biological activity, promote the secretion of insulin and adrenal hormone, improve the activity of lipoprotein esterase, and promote the metabolism and utilization of glucose and fatty acids in liver, fat and muscle tissue. So it can play the role of lowering blood sugar and blood lipid. Polysaccharides sulphate and fucoides polysaccharide can inhibit helicobacter pylori and reduce the occurrence of gastrointestinal tumors. Algal polysaccharide has anti-coagulation, anti-arteriosclerosis, anti-virus, anti-tumor and so on. Seaweed iodine also contains potassium, which is also helpful for expanding peripheral blood vessels and preventing hypertension.

3. Organic iodine from seaweed contains more organic matters,such as fats, amino acids and proteins, and has good stability and is not volatile at high temperature. Inorganic iodine mainly exists in the form of elemental iodine and iodine ion, which is more volatile at high temperature. Using this property can effectively distinguish the true and false seaweed iodine. 

   The inorganic iodine is reduced to iodine ion in the gastrointestinal tract, which is absorbed by the human body in 2-3 hours, and the human utilization rate is low. Organic iodine is more conducive to human storage and utilization. After being absorbed by human body, it will participate in body metabolism. During anabolism, excess iodine can be stored in the form of protein and fat. During catabolism, it breaks down in the body and releases iodine, which is then used by the thyroid gland.

   Inorganic iodine is mainly stored in the human thyroid gland, and excessive iodine can cause poisoning. Organic iodine can be stored in fatty acids throughout the body without causing toxic reactions.

4. pure natural seaweed iodine contains more organic matters and more protein, and a lot of foam is formed on the surface when stirred, the foam automatically disappears after standing for a certain time, while the foam is thin and less after false seaweed iodine is stirred.

5. pure natural seaweed iodine is processed by extraction, multiple vacuum low-temperature concentration and low-temperature crystallization, filtration centrifugation, instantaneous sterilization, full physical production process. PH is alkaline, contains more salts, therefore, the shelf life of pure natural seaweed iodine is more than 5 years if sealled well, the longer it is stored, the richer of seafood flavor. The fake seaweed iodine is made by mixing potassium iodide with monosodium glutamate, chicken essence, pigment and a small amount of kelp liquid extract, which smells bad and has a shelf life of only eight months.

6. Seaweed iodized salt, is a green pure natural iodine supplement, a new concept of health of high-tech biological products. Its good thermal stability, absorbability, safety and adjuvant dietary therapeutic effect make it gradually replace chemical iodine as a new salt iodization additive and more and more popular.
