Inner Beauty Revolution with PureSea® Gold Standard Seaweed

As beauty-from-within continues to evolve, formulators are looking beyond traditional ingredients to create products with a strong point of differentiation. PureSea®  Gold Standard seaweed offers a unique wholefood approach, helping brands develop beauty-focused formulations with the advantage of EFSA-approved skin maintenance claims, thanks to the natural iodine content.

Behind these visible beauty benefits is the thyroid, which plays an important role in cellular renewal and normal physiological function. When thyroid function is compromised, visible changes can appear in the skin, hair and nails. Research has linked low thyroid hormone levels with hair loss¹, dry skin² and brittle nails², highlighting the importance of nutritional support for thyroid balance in beauty-from-within formulations.

PureSea® helps address this challenge through its naturally occurring iodine content. Iodine is required to produce thyroid hormones, which in turn help regulate metabolic processes^3-7 and skin cell renewal⁸. As the only significant natural, plant-based source of iodine, seaweed offers formulators a unique opportunity to develop differentiated beauty-from-within product at a very low dose.

According to the manufacturer, PureSea® is wild-harvested in Scotland’s Outer Hebrides using documented low-impact harvesting practices. The seaweed undergoes controlled drying and milling processes, while DNA authentication and independent certification support product authenticity, traceability, and quality assurance throughout the supply chain.

PureSea® is available as a wholefood ingredient (PureSea® Natural) or a microencapsulated format (PureSea® Protect), enabling seamless integration into a wide range of applications. PureSea® Protect is designed for smooth integration into powders and advanced sports nutrition blends as it benefits from no sea taste or aroma. This versatility makes it ideal for collagen blends, beauty powders, functional foods and other applications where taste is critical.
