Positive Nutrition

Positive Nutrition is a nutritional therapy practice based in Dublin, Ireland, offering personalised nutrition and lifestyle support alongside functional medicine testing. Formerly known as Glenville Nutrition, the practice provides in-person and online consultations, with assessments that consider individual symptoms, medical history, dietary habits and relevant test results.

The practice supports patients with a range of health concerns, including fertility and reproductive health, hormonal imbalances, perimenopause and menopause, digestive problems, thyroid conditions, weight management and chronic fatigue. Its nutritional therapists also provide support for irritable bowel syndrome (IBS), small intestinal bacterial overgrowth (SIBO), food intolerances, polycystic ovary syndrome (PCOS), endometriosis and autoimmune thyroid conditions.

Available functional medicine tests include nutritional and vitamin profiles, gut microbiome analysis, food intolerance testing, SIBO breath testing, thyroid function assessments, fertility-related investigations and hormone testing. Results are reviewed alongside individual symptoms and health histories to inform personalised nutritional recommendations.

The practice develops tailored dietary, supplement and lifestyle plans, with follow-up consultations to review progress and adjust recommendations where appropriate. Its nutritional therapists also work alongside GPs, consultants and other healthcare professionals to complement existing medical care.
