Potassium iodide is a highly soluble form of iodine - an essential micronutrient that the body needs but cannot make on its own. Iodine is a core component of thyroid hormones (T3 and T4), which influence metabolism, energy regulation, temperature balance and more. Supplementing with potassium iodide can help support consistent iodine intake when dietary sources (like sea vegetables, dairy or iodised salt) may be variable.

Individuals seeking nutritional support for healthy thyroid activity

People whose diets are low in iodine-rich foods

Adults wanting to help support normal energy and metabolic pathways

Anyone looking for clean, targeted micronutrient supplementation as part of everyday well-being

Metabolics Potassium Iodide is crafted with clarity, absorption, and uncompromising quality at its core. Providing iodine in a highly absorbable, additive-free form, it’s designed for effortless daily use without fillers or artificial ingredients. Guided by practitioner insight and produced to exceptional quality standards, this formula delivers reliable, transparent nutritional support that works in harmony with the body - helping maintain healthy thyroid function and metabolic balance with confidence.

Potassium iodide is a source of iodine frequently taken by people exposed to radioactive iodine from leaking nuclear reactors such as Fukushima in Japan. Radioactive iodine results from uranium atoms split apart after being struck by a neutron in a nuclear reactor. The thyroid gland cannot differentiate between radioactive iodine and stable non-radioactive iodine Potassium iodide so potassium iodide taken before or shortly after iodine enters the body is absorbed by the thyroid gland resulting in less radioactive iodine being absorbed. So Potassium iodide does not neutralise radiation it simply prevents any more radioactive iodine being absorbed. Although much of the radioactive iodine will be eliminated from the body in a matter of weeks, the radiation can have a very damaging effect on the tissues resulting in genetic mutations.

Current regulations in the USA advise populations living within a 10 mile radius of a nuclear plant to maintain a supply of potassium iodide.

The Scottish Environmental protection agency constantly measures radiation levels in the UK and although increases were noted in 2011 after the tsunami that crippled Japan's Fukushimas reactors, these settled to background levels.

Recently concern lies in more leakage into the water surrounding the reactors and the effects of two further magnitude 5 earthquakes on 8th February 2014 off Japan's Fukushima area are still being monitored.

Thousands of litres of radioactive water are now being stored by Fukushimo leaking 300 tons into the ocean every day.

The Tokyo Electric Power Company (TEPCO) are now considering dumping the radioactive toxic water into the Pacific ocean. On the 7th February 2014 TEPCO admitted that they had detected radiation levels at 160,000 times the state standard for radioactive waste water normally released into the sea.
