OPTI-5 NUTRITION SYSTEM™
The early years are the most critical period in a child’s life. The Opti-5 formula helps parents lay a strong foundation for their child’s lifelong health.
A comprehensive nutritional system featuring over 40 essential micronutrients from high-quality sources, with composition and levels scientifically adjusted to support children at every stage of development.
SCIENCE-LED NUTRITION
FOR THE GOLDEN DAYS OF GROWTH
The Opti-5 Nutrition System™ is a comprehensive, integrated approach to children’s health – developed by our dedicated team of scientists to support optimal growth during the most important years of life.
The name “Opti-5” stands for Optimal Nutrition System – focusing on five key areas of health that are essential during infancy and early childhood, a period we call the “golden days” of development.
Through carefully designed, evidence-based formulations, the Opti-5 System provides targeted nutrients and functional ingredients to strengthen these five vital areas – helping nurture healthy growth, function, and resilience from within.
How the Opti-5 Nutrition System™ Was Developed:
The Opti-5 Nutrition System™ was developed by our scientific team to provide the most comprehensive source of balanced nutrition during the vital early years of growth. Every element was designed to work together – supporting both individual health areas and the natural synergy between nutrients.

COMPREHENSIVE NUTION
Opti-5 delivers all the essential nutrients needed to support the five key areas of growth and development – helping to optimise immune, cognitive, vision, digestive, and overall physical wellbeing.
It also supports nutrient synergies, recognising that nutrients often rely on one another to function effectively. For example:
- Calcium needs vitamin D₃ for proper absorption into the body.
- Vitamin K helps move calcium into bones, where it contributes to strength and density.
Together, these nutrients form a complete system for healthy bone growth – an approach that reflects how Opti-5 formulations are built around natural nutritional teamwork.
BALANCEDAND AGE-APPROPRIATE
Every stage of development has unique nutritional needs. The Opti-5 System is carefully tailored to ensure that each formula provides nutrients in the right amounts and ratios for the age it’s designed for.
During healthy growth: Infants and young children use nutrients more rapidly – especially during their “golden days” of development – so our formulations supply what’s needed to sustain daily growth and function.
When growth is challenged: During times of recovery or increased demand, our nutrient levels help support the body’s natural ability to get back on track – always maintaining safe, balanced proportions.
Through this science-led and holistic approach, the Opti-5 Nutrition System™ helps give little ones the strongest possible foundation for lifelong health and development.


FIVE KEY AREAS OF HEATH
Each of these areas plays a critical role in early life – working independently, yet together, to form the foundation of lifelong wellbeing. These systems are most active and sensitive during the first six years, when nutrition has the greatest influence on physical and cognitive development.
Immune
Building resistance to infection, promoting recovery, and compensating for nutrient loss.
The immune system protects children as they grow. When they are ill, their growth and development take a back seat, while their immune system kicks into gear to help get them back up to speed.
Digestion
Supporting intestinal function, gut immunity, gut microbiome, and preventing diarrhea, colic, or gut infections.
The digestive system controls how nutrients are extracted from food and absorbed into the body, and how waste is removed. When children are sick, nutrients are not absorbed well and are easily lost, affecting growth and energy levels.
Cognition
Nutrients for supporting brain development and activity, including memory formation, coordination, reflexes, social interaction, and emotional well-being.
The brain controls all the body’s systems and growth processes. It is also linked closely to gut health and vision. Sick children tend not to concentrate or interact well and are often tired, unmotivated, and have appetite problems.
Vision
Providing nutrition for the delicate parts of the growing eye to enable good image recognition, learning and hand-eye coordination.
Lower levels of some nutrients can affect all systems in the body, but specific vitamins and minerals (e.g. vitamin A) can cause vision problems. The eyes can also become infected during colds and flu.
Growth & Development
Nutrients that are used by growing tissues contribute to gains in height, strength, and physical movement.
Key nutrients such as amino acids from protein, calcium, and phosphorus are required to support the building up of new tissues, like bone and muscle. Short-term losses in many nutrients cause short-term growth delays.

THE FORMULARS
THESE AREA WITH:
- Advanced nutrient levels – higher, yet safely within recommended ranges
- Targeted functional ingredients, such as Wellmune® Beta-Glucan for immune support and DHA, lutein, and choline for brain and vision health
- Balanced nutrient profiles to help reduce the risk of deficiency and promote steady, harmonious growth.
BALANCED AND AGE-APPROPRIATE
How the Systems Work Together
The five Opti-5 health areas are deeply interconnected. A healthy gut supports a stronger immune system; a nourished immune system protects growth; and good nutrition fuels developing vision and cognition.
By supporting these systems both individually and collectively, Opti-5 helps build a strong foundation for balanced, long-term health and wellbeing.
Why Five Areas?
The human body is a complex network of organs and systems that rely on one another to function optimally. When one system is out of balance, it can affect the entire body.
After years of research, our scientists identified five key areas – Immune, Cognition, Vision, Digestion, and Growth & Development – as the most important and most vulnerable during early childhood. These form the foundation of the Opti-5 Nutrition System™, supporting healthy, connected development from the inside out.
