Boston Functional Nutrition is a place for women who are seeking supportive, individualized care for their wellness and nutritional concerns. Led by a registered dietitian, Boston Functional Nutrition was born out of a desire to support the unique health needs of women by marrying holistic mind-body medicine with evidence-based nutrition therapy, with a focus on recovering hormonal balance.
