PureSea® and Collagen – The Ultimate Marine Match-Up

With growing popularity in the Beauty from Within market, innovation is a must. PureSea® Protect is a microencapsulated seaweed ingredient delivering all the benefits found in the Gold-Standard PureSea® seaweed with none of the flavour or aroma of the sea. It provides sustainable, natural iodine that helps support thyroid hormone regulation, which is key to maintaining healthy hair, skin, and nails (EFSA Claim), whilst Collagen Type I delivers the essential protein structure they depend on.
Pairing PureSea® Protect and Marine Collagen Type I could offer a powerful beauty-from-within solution, as collagen supports elasticity, hydration, and firmness of the skin1, while promoting stronger nails and shinier hair, whereas PureSea® Protect may support the underlying thyroid functions2 that influences their health.
This innovative, sustainably sourced ingredient is available in two distinct grades: the original Gold-Standard PureSea® ingredient and PureSea® Protect – a new, innovative version developed for superior formulation flexibility.
PureSea® Protect offers all the advantages of the original Gold-Standard PureSea®, all thanks to its natural iodine content. In addition to its 'beauty from within' benefits, both grades are produced from DNA-authenticated starting raw materials and are supported by six EFSA Approved Health Claims. These claims include the maintenance of healthy thyroid function, energy-yielding metabolism, cognitive health, and proper functioning of the nervous system, all attributed to their natural iodine content.
Unlike synthetic iodine sources – which may release nutrients too early in the stomach – research on PureSea® Protect has highlighted that it has a lower release rate in the gastric phase. This delayed release helps improve nutrient absorption, with this study using polyphenols as a marker to track how and when nutrients are released.
By pairing PureSea® Protect with our premium Fish Collagen Peptides, formulators can deliver both visible beauty and e inner wellness, using scientifically validated ingredients and EFSA approved health claims for iodine and skin health. Together, these marine-derived ingredients offer a distinctive solution for modern wellness.
