Urine Iodine Test
Is iodine helping or hurting your thyroid? This simple at-home urine test gives you answers.

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.
