Actual date on which the first participant was enrolled.

Menopause and peri-menopause are associated with a number of symptoms and psychological well-being. Previous literature has found a relationship between diet and menopause management. For example, following the Mediterranean diet consuming a variety of vegetables, fruits, legumes and whole grains has found to improve menopausal symptoms particularly vasomotor symptoms. Few studies have explored the effects of dietary supplements on psychological well-being in menopause. The aim of the study is to explore the impact of an iodine-rich seaweed food supplement on menopause symptoms and mental well-being in those experiencing menopause. Online assessments of symptoms will take place pre-intervention and post-intervention and will be compared to the effects of a placebo.
