Fertility Support for men & women with PureSea®

Fertility challenges are on the rise worldwide, with approximately 1 in 7 couples in the UK, struggling with infertility.1 An essential nutrient to consider is iodine. Europe is currently recognised as a region with widespread iodine deficiency, affecting nearly 2 billion individuals worldwide.

Seaweed and iodine have the potential to positively influence fertility in both men and women. This connection stems from the critical requirement of adequate iodine for the optimal functioning of the thyroid gland. The thyroid gland plays a pivotal role in overseeing various metabolic processes within the body, including those related to reproductive health.

PureSea®, gold-standard sustainable seaweed is an organic, plant-based, natural source of essential iodine that could potentially benefit both men and women’s fertility in 5 ways:

Thyroid Function: Iodine is a key component of thyroid hormones, namely thyroxine (T4) and triiodothyronine (T3). These hormones are essential for regulating the body's metabolism, including the menstrual cycle in women and sperm production in men. Proper thyroid function is critical for maintaining hormonal balance and fertility.

Hormone Regulation: Iodine helps in the synthesis and regulation of sex hormones like oestrogen and testosterone. Balanced levels of these hormones are necessary for reproductive health in both men and women. An iodine deficiency can lead to hormonal imbalances that may adversely affect fertility.

Menstrual Cycle: In women, iodine deficiency can disrupt the menstrual cycle, leading to irregular periods or even amenorrhea (absence of menstruation). Maintaining a healthy thyroid and hormonal balance is essential for ovulation and overall fertility.

Sperm Quality: Iodine is also important for men's fertility. Adequate iodine levels can support healthy sperm production and function. Iodine deficiency can result in reduced sperm count and motility, potentially affecting male fertility. 

Antioxidant Properties: PureSea® seaweed contains antioxidants, which can help protect reproductive cells from oxidative damage. Oxidative stress can impair fertility by damaging sperm and eggs.

PureSea® is a well-researched ingredient backed by science which allows up to six different EFSA Health Claims relating to natural iodine source.
