About Ana Sever

Ana Sever is the Founder and Director of Meditrina Health, the company behind Windback.co.nz, a New Zealand wellness business dedicated to science-led nutrition, proactive health and healthy ageing.

Ana holds a Bachelor of Nursing, with an academic focus on nutrition, dietetics and human health. Her nursing education and professional experience working as a nurse in New Zealand provided a strong foundation in human health, patient care and the importance of nutrition and lifestyle in supporting long-term wellbeing.

Her interest in the relationship between nutrition, lifestyle and healthy ageing has remained a defining passion throughout her life, shaping her commitment to proactive health, illness prevention and evidence-informed wellness.

She is a member of the Australasian College of Nutritional and Environmental Medicine (ACNEM) and is committed to ongoing professional education in nutritional medicine, metabolic health, functional medicine and the emerging science of longevity. Her continuing education includes studies with PreKure and Stanford University Online, alongside participation in health conferences, research seminars and professional learning programmes.

Ana's approach to health is grounded in the belief that nutrition, movement, restorative sleep, metabolic balance and lifestyle choices play an important role in maintaining wellbeing as we age. She is particularly interested in how advances in nutritional science, cellular health and preventive healthcare can help people make informed decisions and take a more active role in their long-term health.

An advocate for a proactive, whole-person approach to wellbeing, Ana believes that good health is about more than simply avoiding illness. It is about maintaining the energy, strength, cognitive function and independence needed to enjoy life fully, at every age.

Her interests extend to the growing field of personalised health, including metabolic monitoring, continuous glucose monitoring (CGM), wearable technologies and the use of meaningful health data to better understand how nutrition and everyday habits influence wellbeing. She sees these developments as valuable tools that can complement established principles of good nutrition, healthy living and individualised care.

Alongside her health interests, Ana brings more than 20 years of senior leadership experience across New Zealand and international organisations. She also holds a Bachelor of Commerce (Honours) and a Postgraduate Certificate in Management (Distinction) from Macquarie Graduate School of Management. Her professional background has strengthened her analytical thinking, research skills and ability to translate complex information into practical insights, qualities she now brings to her work in health education and science-led wellness.

Ana is also an alumna of Global Women New Zealand and a member of the Institute of Directors New Zealand.

A deeply personal journey

While Ana's passion for nutrition and health began many years earlier, it was her mother's illness that gave that passion a profoundly personal purpose.

As her mother's health began to deteriorate for reasons that were initially unclear, Ana immersed herself further in nutritional research, holistic health and the complex relationships between lifestyle, chronic illness and wellbeing. This period reinforced her belief in the importance of recognising changes in health early, asking informed questions and taking a proactive approach to caring for ourselves and those we love.

In 2023, Ana made the decision to step away from her corporate career to care for her mother, who had been diagnosed with advanced stage 4 colon and liver cancer.

Her mother passed peacefully at home in January 2025, in Ana's arms, following a courageous journey through her illness.

Walking beside her mother through a time defined by love, faith, joy, dignity and compassion profoundly shaped Ana's understanding of health, resilience and what it truly means to live well.

Her mother's fearless faith, warmth and joyful approach to life remain a constant source of inspiration. That experience strengthened Ana's determination to help others value their health, recognise the importance of early action and make informed choices that support their wellbeing throughout life.

It also reinforced a deeply held personal conviction: food is medicine, and prevention, wherever possible, is more powerful than cure.

The purpose behind Meditrina Health and Windback

Meditrina Health was born from the convergence of Ana's nursing education and clinical experience, lifelong interest in nutrition, continuing health education and deeply personal experience of caring for someone she loved.

Through Windback.co.nz, Ana seeks to make science-led wellness more accessible to New Zealanders by bringing together carefully selected nutritional supplements, evidence-informed health education and practical guidance for everyday wellbeing.

Her philosophy is centred on healthspan, not simply lifespan. She believes the goal of healthy ageing should be to maintain physical strength, mental clarity, vitality and independence for as many years as possible.

Ana is particularly passionate about helping people understand the science behind nutrition, metabolic health, cellular wellbeing and the biological processes associated with ageing. Through her writing and ongoing research, she aims to translate emerging health science into clear, practical information that encourages informed decisions without promising quick fixes or unrealistic outcomes.

For Ana, good health is ultimately not an end in itself. It is what allows us to remain active, enjoy meaningful relationships, pursue our passions and participate fully in the lives we choose to lead.

Her mission is simple: to encourage a more informed, proactive approach to health, support healthier ageing and inspire others to create a life worth living.
