Nutrition for
Every life stage
About Optivance
Optivance is an Australian nutrition brand for the days when good nutrition is harder to keep up with.
Whether you are managing a busy adult routine, training regularly, focused on healthy ageing, supporting an older parent, keeping up with pregnancy nutrition, nourishing yourself while breastfeeding or helping a toddler with a small appetite, Optivance helps make everyday nutrition easier.
Our range includes THE GOOD LIFE NutraSupplement®, a high-protein Formulated Meal Replacement shake for adults, along with nutritional smoothies made for pregnancy, breastfeeding and toddlers.
Each product is thoughtfully formulated to support the needs of a specific life stage, with practical smoothie and shake formats that are easy to prepare and easier to keep up with.
Our Mission
Our mission is to make quality nutrition simpler, more enjoyable and more practical for real daily routines.
Our Science-led products are made around who you are, what stage you are in, and the nutrition support you need to keep going.
Trusted Through Real Life Stages
Our customers choose Optivance because it is easy to use, thoughtfully formulated and made for real life. Their experiences continue to shape our belief that good nutrition should feel clear, practical and easy to keep up with every day.
Support for Life's Changing Needs
Our nutritional smoothies are made for pregnancy, breastfeeding and toddler nutrition, while THE GOOD LIFE NutraSupplement® is our high-protein Formulated Meal Replacement shake for adults.
THE GOOD LIFE NutraSupplement® is designed for busy routines, training lifestyles, healthy ageing and older adults who need a practical option when meals are rushed, missed or less balanced.
For active adults, NutraSupplement® offers a convenient high-protein option when food is not ready after training or during a full day.
For healthy ageing, it helps make protein and key nutrients easier to keep consistent as routines, appetite and nutrition needs change.
For older adults, it provides a simple, easy-to-prepare meal replacement option when cooking, appetite or regular meals become harder to manage.
For pregnancy, our Prenatal Vitamin Shake offers key prenatal nutrients in an easy smoothie format for daily routines.
For breastfeeding, our Breastfeeding Mummy Smoothie is made to support everyday nutrition when meals are rushed and time for yourself is limited.
For toddlers, our Toddler Smoothie provides practical nutrition support for busy family routines and little appetites.
Skip the Hassle, Not the Meal
NutraSupplement® is made to provide broader daily nutrition in a convenient format. It is high in protein, low in sugar and formulated to replace a missed, rushed or less balanced meal as part of a normal diet.

Kristy Petersen is a renowned Australian nutritionist specialising in gut health and children's nutrition — a trusted expert dedicated to the wellbeing of families through optimal everyday dietary practices.
A journey fuelled by passion
Kristy's path into nutrition began with a deep curiosity about how diet shapes overall health — and a particular fascination with the relationship between gut health and wellbeing. That curiosity led her into extensive education and clinical training, where she honed her expertise in gut health and its central role in how the body functions.
Expertise in children's nutrition
Children's nutrition is a cornerstone of Kristy's work. She understands the unique needs of growing children and the long-term impact early dietary habits have on lifelong health. Kristy works tirelessly to help parents provide balanced diets rich in essential nutrients, so every child has what they need to thrive — physically and mentally.
An advocate for maternal nutrition
Kristy's passion extends into maternal nutrition — especially through pregnancy and breastfeeding. She believes ample, well-considered nutrition during these stages sets the foundation for lifelong health for both mother and baby. As a mum of three herself, she understands these needs from lived experience, not just theory.
A holistic, evidence-based approach
Kristy's approach is holistic — she considers how body systems connect, and tailors her advice to the individual. She continually updates her knowledge through research and professional development, so the families she works with always benefit from the latest in nutritional science.
Making a difference
Through her work, Kristy is making a real impact on family health.
