With Australia being the second highest prescriber of anti-depressants in the world, as a health professional with a passion for mental-emotional wealth, I feel compelled to explore anything that has a positive impact on mental and emotional wellbeing.
Over the last 19 years that I have been in practice as a Health Coach for 19 years, I have accrued solid clinical evidence that point to brain allergies, nutrient deficiencies and unhelpful thinking styles contributing to anxiety, mood swings and depression. More recently, I came across a relatively unknown ‘mother’ of all nutrients, non radio-active, inorganic iodine. Iodine is an essential nutrient which means that you need to consume it daily as the body does not store it. Every single cell in the body has an iodine receptor site on it, making it vital to optimal wellbeing. The brain holds a significant number of iodine receptors. Iodine deficiency is a worldwide problem. The World Health Organisation has recognised that iodine is a significant health problem in 129 countries with up to 72% of the world’s population being affected by an iodine deficiency disorder. (WHO IBID 12 Nov. 1998)
Dr Guy Abraham and Dr David Brownstein, imminent world researchers and clinicians on iodine have found that 96% of 6000 humans tested were iodine deficient 
In reviewing some of the research, I have found what a profound role, non radioactive, inorganic Iodine plays in creating mental wealth:
Slowed Brain Function
Studies have shown the correlation between the shortage of iodine and cognitive function, particularly in the gestation period in children. In fact, one study from 2009 found that iodine supplementation in mildly-deficient children helped improve their perceptual reasoning 
Anxiety and Mood Imbalances
Your hormones play a huge role in affecting how you feel. Low hormone levels, such as in the case of hypothyroidism, can leave you feeling down in the dumps. Excess of hormones such as in hyperthyroidism, leads to frequent anxiety or panic attacks. If you have regular feelings like this, it might be a good idea to get your thyroid fully tested before considering a course of action.
Mood Disorders Related to Hormone Imbalance
Hormones and mental health are closely related, especially when we’re discussing thyroid hormone. We’ve got an antidepressant epidemic in this country, and part of the problem is that patients are being prematurely labelled depressed and needing antidepressants when they really just need to balance their hormones through iodine into their thyroid.
Do children need iodine? Without a doubt, the answer is “yes”. Children need adequate amounts of iodine for normal brain development, to form the normal architecture of the glandular tissue as well as for the optimal function of the thyroid gland and the entire hormone system.
Due to the continual and steady exposure to toxic iodine blocking agents (goitrogens) in our daily environment, iodine supplementation is more important than ever, especially in children. Daivd Brownstein and Guy Abrahams believe that iodine deficiency is one of the main causes (or the main cause) of ADHD and autism. ADHD and autism are occurring at epidemic rates right now. They feel that there is an imbalance in the body, particularly, ADHD and autism are a sign of a nutritional and hormonal imbalance. The rapidly falling U.S. iodine levels could explain why we are suffering from an epidemic of both ADHD and autism as well as other childhood behavioral and physical problems
Improved Mental Performance
Improved iodine status was found to be associated with improved mental performance and physical skills in schoolchildren that were iodine deficient .
1.The most accurate way to have your iodine levels checked is through a 24 hour urine load test.
2.It is important to note that simultaneously detoxifying bromide, fluoride and chloride off the iodine receptors is part of the ideal protocol for successfully increasing your iodine uptake inside your body.
3.For accelerated health benefits, ensure that you use an iodine product that contains both iodine and potassium iodide.
4.For a comprehensive thyroid function, ensure you are tested for TSH, FT4, FT3, rT3, Anti TPO, Tgab, Trabs.
