Lamberts Iodine 150µg 180 Tablets is a food supplement that provides 150µg of iodine, as potassium iodide, in every tablet - the full Nutrient Reference Value (NRV) for this mineral in a single dose. Iodine contributes to normal thyroid hormone production, thyroid function and energy-yielding metabolism, making this a straightforward way to support daily iodine intake for those who need it.

Key Features

• Full daily iodine requirement in one tablet: Each tablet provides 150µg of iodine (as potassium iodide), 100% of the Nutrient Reference Value (NRV).
• Supports thyroid function and metabolism: Iodine contributes to normal thyroid hormone production, normal thyroid function and normal energy-yielding metabolism, as well as normal cognitive and neurological function.
• Large 180-tablet pack: At the standard dose, one pot lasts up to 6 months, reducing how often the supplement needs to be reordered.
• Adjustable daily dose: The stated dose of 1 to 2 tablets a day allows intake to be adjusted to individual needs.

Who might need to take an iodine supplement?

Most people get enough iodine from a varied diet that includes foods such as fish, eggs and dairy products. NHS guidance notes that people following a vegan diet, or anyone who avoids fish, eggs, milk and other dairy products, may want to consider iodine-fortified foods or an iodine supplement.

What is potassium iodide, and how much iodine does each tablet provide?

Potassium iodide is the form of iodine used in this supplement. Each tablet provides 150µg of iodine from potassium iodide, meeting 100% of the Nutrient Reference Value (NRV) for iodine.

Is there a safe upper limit for iodine, and should I check with a doctor before taking it?

NHS guidance suggests that taking 0.5mg (500µg) or less of iodine a day from supplements is unlikely to cause harm, and the recommended dose of this product (150-300µg a day) falls well within that. Taking much more than the recommended amount for a long period may affect how the thyroid gland works. Anyone with an existing thyroid condition, or taking thyroid medication, should speak to a doctor or pharmacist before taking an iodine supplement.
