Nascent Iodine: Do UK Citizens Need to Supplement?

Nascent Iodine: Do UK Citizens Need to Supplement?

We have often written about vitamins, minerals and nutrients which are lacking in the traditional British diet.

Iodine is another important element of sound nutrition which many Brits fail to get enough of. This is cause for major concern, since iodine contributes to the thyroid as well as other aspects of health.

In this blog we intend to discuss the importance of iodine – and by extension nascent iodine, the ideal form of the mineral recognised by the body. We’ll also discuss why the public awareness of iodine and its benefits is falling well short in the UK.

What is Iodine?

Iodine is a trace mineral required by the body to make thyroid hormones, which regulate our metabolism.

The body also relies on these thyroid hormones to facilitate the development of healthy bone and brain tissue during pregnancy and infancy. Because we are unable to produce iodine on our own, we must rely on our diet.

With obesity reaching pandemic proportions throughout the western world in particular, the importance of regulating one’s metabolism couldn’t be more obvious.

A natural corollary of low iodine levels is a sluggish metabolic rate due to the thyroid gland’s inability to synthesise necessary amounts of thyroid hormone. The consequence of this chain of unfortunate events is weight gain.

While you may be busy counting calories and breaking a sweat in the gym, an iodine deficiency could unknowingly be hindering your fat-loss efforts.

Iodine for Diabetes and Pregnancy

But it’s not just hormones and metabolism: iodine is needed for healthy skin and proper nervous system functioning. It also increases the excretion of toxic halogens (bromides, fluorine, chlorine) and heavy metals, which we unwittingly ingest every day.

What’s more, there is anecdotal evidence to suggest it can benefit those battling allergies, brain fog, fatigue, psoriasis, type-2 diabetes, depression, cholesterol and lung conditions.

“I have found that type 2 diabetic patients can often stop their oral medication after iodine supplementation, as their blood sugar dramatically improves,” notes Dr. David Brownstein, one of the world’s foremost authorities on iodine and author of the book Iodine: Why You Need It, Why You Can’t Live Without It.

“For those patients treated with insulin, I have been able to lower insulin dosages in nearly every patient treated with iodine.”

Research in 2013 focused on the specific benefits of iodine supplements taken before conception, during pregnancy and during breastfeeding. The analysis suggested iodine supplements could boost children’s IQ scores by an average of 1.22 points; save the NHS £199 per pregnant women; and offer financial benefit for every women equal to £4,476, based on higher earnings and lower education costs for her child.

Separate studies undertaken by the WHO have found an IQ difference of up to 13 points between communities that have adequate amounts of iodine in their diet and those that don’t.

Dietary Sources of Iodine and Why Brits Are Deficient

Cow’s milk is the richest source of iodine in the British diet, and the fact that so many people have adopted vegan diets – and cultivated a love of plant-based milks such as soy and almond – partly explains the rocketing rate of iodine deficiency in the UK.

Britain now has the unfortunate distinction of being one of the top ten most iodine-deficient countries on the planet.

Young women have been identified as particularly at-risk. In a 2011 study of 737 teenage girls, almost 70% were found to have levels below 100 mcg per litre, which is classed as the acceptable “minimum level” by the World Health Organisation.

Almost one fifth of subjects, meanwhile, exhibited troublingly low iodine levels below 50 mcg per litre.

This is especially worrying since pregnant and lactating women actually need more iodine than the rest of us (as thyroid function is ramped up during pregnancy). The results of one 2016 study of pregnant women in Southwest England thus make for grim reading.

Given that iodine deficiency during pregnancy is believed to impair neurological development in the foetus, the finding that median urinary iodine concentrations (UIC) for the 308 subjects were just 88 mcg per litre was cause for serious concern.

Remember, 100 mcg/l is considered the minimum level by the WHO. The results caused the researchers to announce that measures to develop optimum prevention and treatment strategies were “urgently needed.”

Is the RDI for Iodine Sufficient?

The current UK recommended daily intake for iodine is 140 mcg, though the World Health Organisation insist pregnant and lactating women should consume 250 mcg. This is why an increasing number of pregnancy supplements are being fortified with iodine, and why iodised salt is recommended for food preparation.

In the view of many integrated and functional medical doctors, the RDI is woefully insufficient: they contend that it was calculated from how much iodine the thyroid needs to avoid goiter, not perform optimally.

The requirements of other organs were not factored into the number, and nor was a proper consideration of iodine-inhibiting polluters given.

Since 250 mcg is tricky to achieve via diet alone, and kelt and seaweed are not advised as an iodine source for pregnant women, many expert medical groups advise that iodine supplements be taken during and following pregnancy to ensure iodine needs are consistently met.

The WHO make the same recommendation in areas which do not have access to iodised salt. Most salt on sale in Britain is not iodised, and the iodine concentration of the major UK brand of iodised salt is actually very low (115 mcg per kg).

Even if they were high, UK public health campaigns aimed at reducing salt consumption make hitting an RDI – even an insufficient one – very difficult.

Iodine Deficiency: A Public Health Concern in 47 Countries

Of course, it is not just Brits who are deficient. Studying data from 1997 to 2006, the WHO determined that iodine deficiency remained a public health problem in 47 countries, with almost two billion individuals worldwide estimated to be deficient.

Iodine deficiency remains the world’s greatest single cause of preventable brain damage, with the relatively low iodine content of most foods to blame.

As mentioned, cow’s milk is by some margin the greatest source of dietary iodine. That is not to say that it is the only source, however: iodine also crops up in fish (who extract it from seawater) and seaweed; dairy products like cheese and yogurt; and a few specific fruits and vegetables – prunes, cranberries, green beans and watercress among them.

Himalayan pink salt is yet another terrific source, with a half gram yielding 250 mcg of iodine.

Is Iodine Bioavailable?

There is, however, the question of bioavailability. The BBC show Trust Me, I’m a Doctor decided to compare the iodine-raising effects of eating white fish, sea vegetables or milk.

In their human trial, they found that participants were only able to absorb around half as much iodine from the seaweed as from milk or fish. In other words, although sea vegetables were deemed to be a plentiful source of iodine their bioavailability was poorer than from cow’s milk or fish. Indicating, once more, that vegans are particularly at risk of iodine deficiency.

To these at-risk groups (young women, vegans), we should perhaps add those increasing numbers who have begun to follow Palaeolithic diets. According to a 2017 study published in the European Journal of Clinical Nutrition, these common fat-burning diets put one at a higher risk of iodine deficiency.

Do Other Factors Influence Iodine Deficiency?

Aside from insufficient dietary intake, other factors impact our iodine levels. As noted by Lynne Farrow in her book The Iodine Crisis, “iodine is vulnerable to displacement by environmental toxins such as bromide, pesticides and food additives… Bromine fire retardants surround us. Introduced in the 1970s, they have accumulated in our homes, cars and work places.”

Indeed, Farrow is convinced that our bromine-saturated environment has much to answer for, pointing out that “iodine is the biochemical antidote for toxic bromine but it takes time. Bromine is a persistent chemical bully. Like any bully, it has to be outflanked, outnumbered and outwitted. The right dosage of iodine is your ally.”

Such is its use in pesticides, plastics, prescription medications, baking ingredients, electronics and upholstery, bromine is rather tricky to avoid.

Ensuring a sufficient intake of iodine – whether by eating plenty of iodine-rich foods, using a good-quality supplement or both – is vital to minimise the potential damage. Otherwise, bromine will bully what little iodine we get through our diet off the receptors.

It is also wise to avoid other health-damaging chemicals known to block iodine uptake, not least fluoride and chlorine. You can reduce the fluoride and chlorine content of your drinking water by using a multi-stage undersink system such as the Energy Plus. The water filter also removes heavy metals, chloramine, herbicides and other unnatural components of drinking water.

How Iodine Metabolism is Hindered by Goitrogens

Lastly, eating an abundance of goitrogenic food is best avoided. Goitrogens are substances which interfere with the way our body utilises iodine.

They are found mainly in plant foods such as soy and cruciferous vegetables like broccoli, cauliflower and cabbage. If our iodine intake is healthy, consuming reasonable amounts of these foods won’t do us much harm.

However, if we’re already hovering near deficiency and goitrogenic foods constitute the bulk of our diet – as is likely for vegans – it spells worry.

Nascent Iodine: UK Citizens’ Need to Supplement

Public Health England insist that a varied diet should provide all the iodine you need. However, PHE is so anti-supplement that this advice should be taken with a good-sized pinch of salt.

We have made references to several studies indicating chronic deficiency among the population at large, and there are many more. Unless you are drinking plenty of cow’s milk and/or regularly eating seafood and seaweed, you are simply unlikely to be getting enough.

Nascent iodine is a form of supplemental iodine available in atomic rather than molecular form. Highly bioavailable, it is recognised by the human body as the same iodine which is taken up by the thyroid, and is thus rapidly absorbed.

Nascent iodine can be taken sublingually (placing drops under the tongue), or alternatively you can add a drop to water and drink. As a wellness supplement, nascent iodine has been used since the 1920s.

The brand of Nascent Iodine we stock is from Harmonic Innerprizes, a company founded in 1994 and well known for their pioneering work on monatomic elements. Their proprietary Pureodine™ process enables them to make nascent iodine utilising only glycerin and pure elemental iodine: no alcohol, water or other ingredients.

This glycerite of nascent iodine is completely unique in the market and offers far superior stability compared with nascent iodine supplements of the past. A single drop of this high-quality, super-absorbable iodine yields 450 mcg.

Recommended Dosage for Iodine

You may be wondering whether a dosage of 450 mcg is really necessary. But similar dosages are recommended by physicians Guy Abraham, MD, and the aforementioned David Brownstein, MD.

Indeed, their iodine supplement protocol recommends 500 mcg of iodine daily. (They also recommend several adjuncts including 3,000 mg of vitamin C, 300-600 mg magnesium, 200 mcg selenium and half a teaspoon of unprocessed sea salt.)

It is worth noting that the tolerable upper limit of iodine is 1,100 mcg per day, so 450 mcg is perfectly safe for consumption. Women with pre-existing thyroid conditions, however, should seek advice from their medical practitioner prior to taking this or indeed any nutritional supplement.

It is easy to see the value in consuming nascent iodine. UK citizens would do well to follow the work of The UK Iodine Group, a collective of experts in iodine nutrition who have tasked themselves with eradicating iodine deficiency domestically. But truthfully, this is a global problem and one which requires a sustained and committed response.
