About Iodine :
Iodine is listed as one of the 64 “minerals of the genetic code” (1)
It is coupled with and requires the amino acid Glutamine. It is stored and regulated in the thyroid gland and is the major component in making the hormone thyroxine.  There is a relationship between iodine and potassium – if iodine is deficient then often so is potassium. Caffeine toxicity coupled with a deficient iodine can lead to fibrocystic tumours and cysts.
When women are iodine deficient they crave chocolate.
Those who live near the ocean are likely to receive a reasonable amount of iodine from the seaside atmosphere.
 
The brain can’t develop without iodine – a baby who develops without iodine will be born mentally retarded and have irreversible brain damage. Adults with low iodine struggle with below average IQ and mental abilities, plus reduced motor skills. Low iodine through childhood develops in to goitre (enlarged thyroid) later in adulthood. Low basal body temperature is associated with low iodine.
Fluorine inhibits iodine uptake by the thyroid gland which results in an underactive thyroid, low thyroxin, inability to metabolise sugar (heading towards diabetes !), fats, amongst other problems as well. Iodine protects the brain against harmful toxins, protects the thyroid from x-ray and radiation exposure (potassium iodide), assists with the assimilation of phosphorous, calcium, silica (all needed for bone strength), is found in the blood / spleen / tears /  perspiration, is essential for thyroid, spleen , liver and brain function, neutralises albumin. Iodine needs selenium for good absorption
 
Benefits of iodine / potassium iodide : promotes a healthy thyroid, brain, helps you live longer, may help to prevent breast cancer (and cancers generally), helps the body to remove toxic halogens such as bromide, fluoride, and chloride, assists in keeping intestinal parasites under control, maintain motor skills, wards off cholesterol build up in arteries, manage - weight gain, joint pain, infertility, energy and heart disease and more.
 
Iodine is not stored in the body, which means we need to get our daily requirements from our diet. As modern foods are either lacking in it or the iodine content is compromised (by chemicals, fluorides, etc), then supplementation is something many people need to resort to. It is helpful to keep an eye on your thyroid function via blood tests (see your GP). If you are on thyroid medication, please consult with your GP before deciding to use this formula.
 
How to Take :
Approximate measurements :
1 drop = approx. 0.01ml. At 10% solution. This solution is in a strength that does NOT require more than 1 drop daily to improve and maintain iodine levels.
DO NOT take more than 1 drop at a dose
1 drop daily in water is the recommended dose. If your levels are known to be very low, maintain this dosage daily for about 2 – 3 weeks then reduce to 1 drop every 2 – 3 days or take for the 2 days over a weekend or as you feel is needed. (guideline only)
