GLP-1 & Thyroid Health: How PureSea® Delivers the Right Support
- 09 February 2026
- Written by LEHVOSS Nutrition
As interest grows in GLP‑1 focused products that help manage appetite, more brands are searching for complementary solutions that support nutrition whilst using GLP-1 products as well as long term, efficient, metabolism support.
This is where thyroid health – and PureSea® – plays a key crucial supporting role, as PureSea® offers consistent wholefood nutrition through a natural, clean label, traceable and sustainably sourced seaweed ingredient.
Normal thyroid function1,2 drives the body’s metabolic rate, and this process depends on a reliable supply of iodine. As a natural source of iodine PureSea® helps maintain healthy thyroid hormone production, providing steady metabolic support that fits everyday nutritional needs.
The thyroid plays a key role in metabolism, influencing how efficiently food is converted into energy. Over 5 billion people — around 68% of the global population — are estimated to be iodine-deficient3, which can lead to thyroid-related issues. Maintaining a consistent intake with a natural resource as PureSea® is important for supporting metabolic function4.
PureSea® is the gold-standard, nutrient‑dense seaweed ingredient that offers a unique solution thyroid health. As a natural source of iodine, it enables six EFSA‑approved health claims related to normal thyroid function, energy‑yielding metabolism, cognitive health and more, all supported by exceptional provenance and proprietary production PureSea® is available in two forms: PureSea® Natural, a wholefood seaweed naturally rich in nutrients, and PureSea® Protect, a microencapsulated version with none of the sea’s flavour or aroma, ideal for combining with other ingredients, minerals or in power blends.
