Why Test Your Iodine Levels?

If you’re not sure whether you have adequate amount of iodine, or if you're low, then you need this test.

Excess iodine can trigger thyroid flares, disrupt gut health, and increase antibodies for women with underactive thyroid, or Hashimoto’s. But deficiency can also impair thyroid hormone production.

Rather than guessing what your iodine amount is, this test shows you exactly where your iodine levels sit, so you can personalise your thyroid support confidently.

This Test Is Best For You If:

You have Hashimoto’s or thyroid autoimmunity

You experience worse thyroid symptoms after changing supplements

You want a clear baseline before adding in or adjusting iodine intake

What’s Included?

At-home urine test kit

Laboratory analysis of your iodine levels, processed in a UK accredited lab using advanced ICP-MS methodology.

Easy-to-follow collection instructions

UK shipping included

Results emailed directly to you

If chosen, you'll also get a video interpretation of your test result

Why This Test Matters:

For some women with thyroid issues, iodine levels can shift dramatically due to diet, supplements, or autoimmune activity. This test helps you make informed decisions with expert-level data specific to your body.

No more guessing if you need supplements with iodine in them or not

Avoid accidental iodine overload from foods and "thyroid support" products

Get confident data before making changes to your plan

Reduce risk of unnecessary thyroid flares
