Why should I take an iodine-free multivitamin?

 The complete guide to multivitamins: what do they do?


In theory, we should get all the vitamins and minerals we need from a healthy, balanced diet. But, sometimes, this just isn’t achievable. And there are many possible reasons for this: rising stress levels can deplete the body’s nutrient reserves; the demands and pressures of modern life often make unhealthy, nutrient-poor, convenience food more appealing; and pollution, toxin exposure, and soil nutrient depletion can inhibit nutrient intake.
 
Supplementing with a multivitamin can be a helpful insurance policy to cover these nutritional shortfalls. Multivitamin formulas aren’t a substitute for healthy eating. Instead, they simply plug small but meaningful gaps to prevent low nutrient intakes.
 
Of course, everyone’s nutritional needs vary depending on circumstance, age, and gender. And for some people, taking an iodine-free multi is the most appropriate choice. Here, we take a look at some of the reasons why.
 

What does iodine do in the body?

 
Iodine contributes to the normal production of thyroid hormones and normal thyroid function. It also contributes to normal cognitive function, energy-yielding metabolism, the normal functioning of the nervous system, and the maintenance of normal skin.
 
Iodine is an important trace mineral required at all life stages, especially during the early years. That’s why women need slightly more iodine during pregnancy.
 
Since the body can’t produce iodine, you need to ensure an adequate and comprehensive supply from food sources, such as those of a marine origin, like shellfish or seaweed.
 
There’s no doubt iodine is vital for good health; your entire metabolism and thyroid depends on it. But some people need to exercise caution when it comes to supplemental iodine. 
 

Thyroid issues and supplemental iodine

 
Given iodine role in thyroid function, you should always choose an iodine-free multivitamin if you experience thyroid issues, such as hypothyroidism (an underactive thyroid) or hyperthyroidism (an overactive thyroid). Taking too much may exacerbate your condition and worsen your symptoms.
 
For instance, if you suffer from hyperthyroidism (an overactive thyroid), supplementing with iodine may lead to increased episodes of anxiety, irritability, insomnia, and weight loss.
 

Medication and supplemental iodine

 
Supplemental iodine is known to interact with certain medications, especially those used to manage thyroid conditions. Lithium (a mood stabiliser) and blood pressure medication may also negatively interact with iodine. If you take these medications regularly, we recommend choosing an iodine-free multi.
