The role of PureSea® & Beauty from Within

PureSea®, gold-standard sustainable seaweed has benefits nutritionally for beauty-from-within, thanks to the natural source of nutrition that it provides. This centres on iodine – a nutrient which is essential for many aspects of health, including optimising the condition of hair, skin and nails. A diet deficient in iodine can lead to an underactive thyroid (hypothyroidism), common symptoms of which include hair loss, dry skin and brittle hair and nails. Let’s take a look at this into more detail:

Hair: When thyroid hormone levels are low, the rate at which hair grows can be reduced and even stop completely. Therefore, it is unsurprising that many people who have suffered from iodine deficiency disorders have also experienced hair loss. In fact, in a study of 700 participants, it was found that 30% of those that presented with low thyroid hormone levels had experienced some form of hair loss.1

Nails: Nail health can also be impacted by thyroid issues, with one reason for this being that a reduced metabolic rate impacts the amount of sweat produced by the body. Sweat plays a role in maintaining the moisture of the skin and nails and in its absence, it can cause them to become dry and brittle. In more extreme cases, a condition known as onycholysis can occur – a condition where the nail becomes separated from the nail bed.2

Skin: Another common symptom of iodine deficiency is dry, flaky skin. This has been attributed to a lowered rate of skin cell regeneration as a result of lower thyroid hormone levels.3 In one study, 63% of people with hypothyroidism reported that they were suffering with dry skin.1

Iodine plays such a key role in skin health, that products containing a good source of the nutrient can use an EU approved health claim surrounding the maintenance of skin, making PureSea® ingredients a great choice. The powders and granules are supplied in various formats, for ease of use in nutrition, food and beverage products.
