The studies below reference peer-reviewed research on the key active ingredients in this product. These are ingredient-level studies.
Iodine (from Kelp, potassium iodide)
-
Ma et al., 2016 · European Journal of Nutrition
Randomized controlled trial; n=112; 6 months; participants with mild iodine deficiency
Participants with mild iodine deficiency who received iodine supplementation showed statistically significant improvements in urinary iodine concentration and thyroid function markers compared to those who received no supplementation; results are specific to deficient populations and may not reflect outcomes in iodine-sufficient individuals.
-
Clark et al., 2003 · American Journal of Clinical Nutrition
Randomized, double-blind, placebo-controlled crossover trial; n=36; multiple treatment periods; healthy adults
Healthy adults who received kelp as a dietary iodine source showed measurable increases in urinary iodine excretion compared to those who did not receive kelp; the study authors noted that high doses of kelp-derived iodine produced elevations in serum thyrotropin, indicating a potential dose-dependent effect on thyroid function.

How it works
Every ingredient, chosen with intention.
Here's what's in this bottle - and why each ingredient earned its place in the formula.

Iodine from sea kelp and potassium iodide
A trace mineral the thyroid gland uses to synthesize T3 (triiodothyronine) and T4 (thyroxine) hormones, which regulate metabolism, energy production, and other physiological processes throughout the body.
Why we chose itSourced from two complementary forms: sea kelp for the whole food plant matrix, and potassium iodide for precision and consistency. Kelp's iodine content varies naturally harvest to harvest, the potassium iodide standardizes the total to a reliable 225mcg in every tablet.

Questions, answered
What customers often ask.
Why do vegans need to supplement iodine?
Iodine in the food supply comes mostly from dairy (where cows are supplemented) and seafood. Plant-based diets that avoid both, and don't regularly use iodized salt, tend to fall short of the daily reference amount. A consistent daily iodine source helps your body maintain the levels your thyroid relies on.
Can I take this if I have a thyroid condition?
Please consult your healthcare provider before supplementing iodine if you have a diagnosed thyroid condition or are on thyroid medication. Iodine intake, even at moderate levels, can interact with certain thyroid conditions and medications in ways that require professional monitoring.
Why does this use both kelp and potassium iodide?
Kelp's natural iodine content varies from harvest to harvest, making it unreliable as a sole source. Potassium iodide standardizes the total to a consistent 225mcg per tablet. The kelp contributes the whole plant matrix; the potassium iodide makes the dose precise.
How long until this makes a difference?
Research in participants with mild iodine deficiency shows that iodine status can normalize within weeks of consistent supplementation. For broader thyroid-related changes, the timeline is longer and depends on individual baseline levels, your healthcare provider can test iodine status if you're curious about your starting point.
When should I take this tablet?
Any time of day works. There's no significant timing advantage for iodine. Many people take it with breakfast as part of a morning supplement routine. You can take it with or without food.
Can I stack this with Vegan B12?
Yes, iodine and B12 are two of the most common nutritional gaps on a fully plant-based diet. Taking both daily addresses two different needs: iodine for thyroid function, B12 for energy metabolism and nervous system support. They don't interact.
