Clinging to the rocky, wave-lashed coastlines of the North Atlantic — from the craggy shores of Iceland and Ireland to the cold Canadian Maritime provinces — Palmaria palmata — Dulse — has been gathered, dried, and eaten by coastal peoples for over 1,500 years. In Ireland, it is still sold as a snack food in seaside markets; in Iceland, it was a staple food for Viking Age farmers; and in Atlantic Canada, it remains a beloved regional food tradition. Its Gaelic name 'duileasc' has been in continuous use since at least the 7th century CE.
Dulse is one of the most nutritionally complete sea vegetables available — a true ocean superfood delivering natural iodine for thyroid support, significant plant protein (up to 25% by dry weight), complete B-vitamins including B12 (exceptionally rare in plant foods), iron, potassium, magnesium, and a broad antioxidant polyphenol profile. Its iodine content, while lower than brown seaweeds like Bladderwrack, is significant enough to meaningfully support thyroid hormone production without the risk of iodine excess. Dulse is also a source of phycoerythrin — the red pigment responsible for its distinctive burgundy color — which has shown anti-inflammatory and neuroprotective properties in preliminary research. For those following plant-based diets, dulse offers one of the rare sea-sourced B12 and iron combinations. In Scottish and Norse folk traditions, sea plants like dulse were used in prosperity spells and protection charms — tied to the elemental power of the ocean and the blessings of sea spirits.
For a comprehensive sea-mineral and thyroid-supportive blend, pair Dulse with our Nettle Leaf — a land-based mineral powerhouse — our Irish Sea Moss for synergistic sea mineral and prebiotic support, and our Bladderwrack for a deeper iodine and fucoidan complement.
Dulse contains iodine — those with thyroid conditions (hyper- or hypothyroidism, Hashimoto's, Graves') should consult their physician before regular use. Quality sourcing matters: sea vegetables can accumulate environmental contaminants depending on their harvest location. Those on blood thinners should use with awareness as dulse may have mild anticoagulant activity. As always, consult a qualified healthcare practitioner before use, especially if you are pregnant, nursing, or taking medications.
* Complete ocean superfood — protein, B12, iron, iodine, potassium, magnesium in one sea plant
* Supports healthy thyroid function with natural, food-source iodine
* One of the rare plant sources of B12 — valuable for plant-based diets
* Phycoerythrin pigment shows anti-inflammatory and neuroprotective properties
* Traditionally eaten by coastal peoples of Ireland, Iceland, and Atlantic Canada for over 1,500 years
* Used in Scottish and Norse folk traditions for prosperity, protection, and ocean-spirit connection
1. Measure 1–2 teaspoons of dried Dulse per 8 oz of water.
2. Add to cold water, bring to a simmer, and steep covered for 10 minutes.
3. Strain and drink warm — the flavor is salty, savory, and distinctly oceanic.
4. Drink 1 cup daily as a mineral tonic. Dulse's moderate iodine content makes daily use appropriate at 1–2 servings.
5. Can also be added directly to soups, broths, and salads as a mineral-boosting food ingredient.
For a full sea-mineral thyroid support blend, combine Dulse, Bladderwrack, and Nettle Leaf. This ocean-land mineral trio provides comprehensive thyroid and mineral nutrition.
