Health 4 U
EMPOWERING WELLNESS THROUGH SCIENCE
Personalised Gut, Hormone & Metabolic Health — Expert, Nurse-Led Health & Nutritional Care
Support for bloating, fatigue, weight gain, low energy and hormone-related symptoms using nutrigenomics and personalised nutrition.
Personalised Support for Sustainable Health
Sinéad specialises in supporting busy women over 35 who are experiencing bloating, fatigue, weight gain, low mood, irritability, and reduced energy, helping them restore balance, confidence, and a positive mindset in a way that fits real life.
As a Registered General Nurse (ABA / NMBI) and Registered Nutritional Practitioner (ANP), Sinéad brings a unique blend of clinical experience and personalised nutrition to every client she works with. Her approach is grounded in evidence-based care, compassion, and a deep understanding of how gut health, hormones, metabolism, and lifestyle interact.
Where appropriate, functional and genetic testing is used to provide clarity and insight into a client’s health picture, allowing for truly individualised nutrition and lifestyle plans — focused on identifying contributing factors rather than masking symptoms.
In addition to individual client work, Health 4 U delivers corporate diagnostic health screening services, providing on-site cardiometabolic point-of-care testing (POCT) for organisations. These services offer rapid results, practical guidance, and workplace-relevant health insights to support employee wellbeing and long-term health outcomes.
Corporate Diagnostic Health Screening
Personalised Nutrition, Testing & Programmes
Available exclusively for corporate clients, Health 4 U provides advanced on-site diagnostic health screening focused on cardiometabolic risk — one of the leading contributors to long-term illness, absenteeism, and reduced workplace performance.
Using state-of-the-art Point of Care Testing (POCT), employees receive results within minutes, along with clear, practical guidance on what those results mean and how to reduce risk through lifestyle and preventative health strategies.
These screenings support organisations to improve employee wellbeing, productivity, and engagement, while helping to reduce sickness absence and long-term health costs — all delivered through a professional, nurse-led service aligned with workplace wellbeing frameworks.
Health 4 U specialises in personalised nutrition and lifestyle support, grounded in naturopathic nutrition and a strong clinical nursing background. The focus is on identifying the root cause of symptoms — not simply managing them — so clients can achieve sustainable, long-term health.
Sinéad offers a range of individualised programmes designed to support gut health, metabolism, hormones, energy, and overall wellbeing. Where appropriate, functional and genetic testing is used to provide deeper insight and guide targeted, personalised recommendations.
Support is delivered through structured programmes and an online client platform, allowing individuals to begin their health journey with clarity, education, and ongoing guidance — at a pace that fits real life.
Gain Control of Your Health — and Restore Balance for Life & Work
Whether you are managing ongoing symptoms, navigating a demanding stage of life, or simply feeling run down from the pressures of work, family, and everyday stress, Health 4 U offers professional, personalised health support tailored to you.
Support is available for adults at all stages of health — from those with complex or persistent symptoms to those seeking evidence-based nutrition, lifestyle, and wellbeing guidance to improve energy, resilience, and long-term health.
