The HA Nutritionist

Julia Haarhuis, the HA Nutritionist, helps women who have functional hypothalamic amenorrhea (HA). HA happens when your body is under stress, often due to a combination of low energy intake, moderate/high intensity exercise, and stress. During HA, your body is in 'survival mode'; it minimises energy expenditure by stopping functions not essential for survival, such as menstruation.

Our mission is to give women science-backed nutrition and lifestyle guidance to restore their periods.

Julia Haarhuis is a PhD researcher and HA Recovery Nutritionist. After recovering from over two years of hypothalamic amenorrhea (HA), Julia now combines scientific insight with lived experience to help active & high-performing women support their cycles through nutrition.
