Dulse is a whole sea vegetable dense in naturally occurring nutrition — trace minerals, iron, potassium, B12, and iodine — in the form nature assembled them.
I've used dulse in my clinical practice for over 20 years. What makes it valuable isn't any single nutrient; it's the whole-food matrix. Dulse supplies a broad cross-section of trace minerals in a highly absorbable form, along with a moderate, naturally occurring level of iodine that supports normal thyroid function — without the concentrated dose of an isolated iodine supplement.
Dulse is also one of the few plant sources of B12, which makes it worth knowing about for anyone eating a plant-based diet.
Sea vegetables have a long traditional history of use as mineralizing foods, and dulse is among the cleanest. I went to considerable lengths to source the purest dulse I could find — wild-harvested from cold North Atlantic waters off the eastern seaboard, certified organic, and tested for heavy metals and contaminants.
This is a single-ingredient product. Dulse, and nothing else.

Frequently Asked Questions
Q: How much iodine is in Dulse Capsules?
A: A moderate, naturally occurring amount — enough to support normal thyroid function without the concentrated dose of an isolated iodine supplement. Dulse delivers iodine within a whole-food matrix of complementary trace minerals.
Q: I have a thyroid condition — is dulse right for me?
A: If you're managing a diagnosed thyroid condition or taking thyroid medication, talk with your healthcare provider before adding any iodine-containing supplement. Individual needs vary, and that conversation is the right place to start.
Q: Is the dulse organic?
A: Yes — our dulse is OCIA certified organic and wild-harvested from clean North Atlantic waters. It is tested for heavy metals and contaminants. Because the capsule shell is not an organic-certified component, the finished product carries a "made with organic ingredients" claim rather than a full USDA organic seal.
Q: How is Dulse different from other iodine supplements?
A: Most iodine supplements deliver isolated potassium iodide or molecular iodine. Dulse is a whole sea vegetable that provides iodine alongside B12, iron, potassium, and a full spectrum of trace minerals.
Q: Where does the dulse come from?
A: It is wild-harvested from the cold, clean waters of the North Atlantic off the eastern seaboard of the United States and Canada, then dried and milled. Every lot comes with a certificate of analysis.
