Our science

    Nutrition designed for how your body actually works.

    Healthy ageing isn't about chasing miracle ingredients.

    It's about understanding how the body changes over time and creating nutrition that works with those changes, not against them.

    Every BOLD formulation begins with science, guided by research and developed to support strength, movement, bone health and healthy ageing.

    Explore our philosophy

    Science before supplements.

    We don't formulate around trends. We formulate around biology.

    Every ingredient is selected because it serves a specific purpose in helping the body stay strong, active and healthy as we age.

    Evidence-led formulation

    Every ingredient is selected for a specific physiological purpose and supported by published research.

    Nutrition scientist formulated

    Developed with nutrition scientist Louise Fisher to reflect current evidence in healthy ageing.

    Designed for absorption

    Because nutrients only matter if your body can actually use them. Ingredient form, combinations and digestive support all matter.

    Australian owned & operated

    Thoughtfully formulated in Australia for healthy ageing.

    The people behind the science

    Guided by experts.

    Every BOLD formulation is informed by experts in nutrition, healthy ageing and movement. Their combined experience helps ensure our products are grounded in evidence and designed for the real challenges of ageing well.

    The longevity nutrient

    Protein. The single most important nutrient for healthy ageing.

    From the age of 50, the body becomes less efficient at using protein — a process called anabolic resistance. The same meal you ate at 30 no longer delivers the same repair signal. Today's longevity research is clear: older adults need more protein, not less, to maintain muscle, bone, immunity and energy.

    1.2–1.5g

    per kg bodyweight, daily — what experts now recommend after 50.

    the protein needed at 70 vs 20 to trigger the same muscle response.

    25–30g

    per meal — the sweet spot for muscle protein synthesis.

    Active adult over 50 living boldly

    Four principles behind every BOLD formula.

    Systems, not single ingredients.

    The body doesn't use nutrients in isolation. Protein, vitamins, minerals and healthy fats all work together. So do we.

    Better  absorption.

    Nutrition isn't just about what goes in. It's about what gets absorbed. That's why digestive support and nutrient interactions matter.

    Every ingredient earns its place.

    No trendy ingredients. No unnecessary fillers. If it doesn't improve the formulation, it doesn't belong.

    Healthy ageing is connected.

    Strong muscles support healthy bones. Healthy digestion supports nutrient absorption. Energy supports movement. Everything is connected.

    How we build a formula.

    1. Research

    We review the latest scientific literature.

    2. Understand the biology

    We identify age-related nutritional needs.

    3. Review clinical evidence

    We evaluate safety, efficacy and relevance.

    4. Select ingredients

    We choose high-quality ingredients with a clear purpose.

    5. Optimise absorption

    We consider bioavailability, synergy and digestive support.

    6. Test nutrient interactions

    We ensure ingredients work well together.

    7. Final formulation

    We create effective, evidence-based formulas you can trust.

    Our complete protein system

    Better absorbed. Built for the body after 50.

    Most protein powders just give you protein. Bold Health Protein Boost is designed as a complete system — pairing high-quality plant protein with the digestive support, minerals and energy nutrients your body needs to actually use it.

    Organic pea & brown rice protein

    A complete amino acid profile from plants — gentle on digestion and easy to absorb after 50.

    Digestive enzymes + prebiotic fibre

    Helps your body actually break down and use the protein you eat — overcoming age-related absorption decline.

    Calcium, magnesium & vitamin D

    Supports the muscle-bone system as a whole, not just one part of it.

    B12, folate & algal DHA

    Energy-metabolism and brain-health nutrients to help you feel the difference day to day.
