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.
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.

With deep knowledge of medications, supplements and interactions, Alexandra helps ensure our formulations are safe, effective and grounded in clinical practice.
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 longevity nutrient
Protein. It really does matter more after 50.
Protein is essential throughout life, but as we age, our bodies become less efficient at using it to maintain and build muscle. This is known as anabolic resistance.
Getting enough quality protein, spread across the day, becomes increasingly important for maintaining muscle, supporting bone health and staying strong and active.
1.2–1.5g
per kg bodyweight, daily. What experts now recommend after 50.
50%
of bone volume is protein. It's an essential nutrient for long term health
25–30g
per meal. It's important to spread your intake across the day.
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.

Same Food, Different Number: How Drying and Frying Multiply Energy
A baked potato and a bag of crisps start as the same food, yet one has nearly six times the energy. We compared 12 everyday foods with their dried, fried or concentrated versions using Australian data. Here's what's really going on, and why dried fruit still deserves a place in your pantry.

Mayo or Mustard? The Most Energy-Dense Foods in Your Kitchen.
Mayonnaise has nearly eight times the energy of mustard, gram for gram. We ranked 23 everyday foods by kilojoules using Australian data, from oils and nuts to spreads and condiments, and looked at what each one brings besides energy. We also found a few "healthy" snacks that pack more than you'd think. Dense doesn't always mean bad.
