The Role of Puresea® in Healthy Fertility & Pregnancy

Iodine is an essential component of the thyroid hormones T3 and T4, meaning that inadequate intake can result in hypothyroidism (an underactive thyroid). Hypothyroidism can subsequently result in adverse effects on female fertility, by impairing the developmental process of ovarian follicles and ovulation.1

Finding natural solutions to the increasing prevalence of iodine deficiency that can suit all dietary needs and improve fertility and pregnancy outcomes is of vital importance. One of the most natural solutions is through the use of PureSea® gold-standard seaweed ingredients in food supplements to provide a natural, plant-based source of iodine.

Iodine is required in higher amounts during pregnancy due to its critical role in foetal neurological development, with deficiency associated with an increased risk of congenital anomalies, miscarriage and stillbirth.2 It is imperative for women of childbearing age, who are hoping to conceive in the future, to achieve iodine sufficiency as foetal neurological development commences in very early pregnancy.3 Click here to read about the importance of iodine for fertility and pregnancy.
