The Key Pillars of Longevity: Diet, Exercise and Supplements

As we venture further into 2025, the pursuit of a longer, healthier life has evolved from a fringe interest into a mainstream science. Research into longevity has exploded, with groundbreaking studies revealing that how long we live—and how well we live during those years—is far more malleable than previously thought.

The science of longevity points to three fundamental pillars that form the foundation of a longer, healthier life: diet, exercise, and strategic supplementation. Together, these elements create a powerful framework for extending not just lifespan (how long you live) but healthspan (how long you remain healthy).

Diet: The Cornerstone of Cellular Health

What we eat doesn't just affect our weight or energy levels—it fundamentally alters our cellular biochemistry, gene expression, and the rate at which we age.

The Longevity Diet Principles

Research from the world's longest-lived populations, or "Blue Zones," reveals remarkable consistencies in dietary patterns that promote longevity:

• Plant-centric approach: Approximately 80-90% of food consumption comes from plants, particularly legumes, whole grains, and a diverse array of vegetables
• Moderate protein intake: Excessive protein, particularly from animal sources, activates mTOR signalling, which may accelerate ageing when chronically elevated
• Healthy fat sources: Olive oil, nuts, seeds and fatty fish provide essential fatty acids that support cellular membrane health and reduce inflammation
• Polyphenol-rich foods: Berries, dark chocolate, green tea, and specific herbs contain compounds that activate longevity pathways

"The foods that create the greatest cellular resilience and stress resistance tend to be those that our ancestors consumed for millennia—not ultra-processed, novel foods that our biochemistry hasn't evolved to process efficiently."

Fasting Strategies for Cellular Rejuvenation

The timing of when we eat appears to be nearly as important as what we eat. Various fasting protocols have demonstrated remarkable effects on cellular health:

• Time-restricted eating: Confining food intake to an 8-12 hour window allows metabolic systems to reset and triggers cellular cleanup mechanisms
• Periodic longer fasts: More extended fasting periods (24-72 hours) several times per year can initiate more profound autophagy (cellular self-cleaning)
• Fasting-mimicking diets: Structured protocols that provide specific macronutrient compositions to simulate fasting while still consuming some food

Recent studies show that these approaches can reduce inflammatory markers, improve insulin sensitivity, and even remodel the gut microbiome to support longevity.

Exercise: Programming Your Body for Resilience

Physical activity doesn't just build muscle and cardiovascular capacity—it fundamentally rewires our metabolism, hormone production, and cellular signalling in ways that combat ageing.

Four Exercise Modalities for Longevity

A comprehensive approach to exercise for longevity includes:

1. Zone 2 Cardiovascular Training

This moderate-intensity cardiovascular training (where you can still hold a conversation) improves mitochondrial efficiency and metabolic flexibility. Studies show that 150-180 minutes weekly of Zone 2 training significantly reduces all-cause mortality risk.

2. Resistance Training

Maintaining muscle mass becomes increasingly crucial as we age. Research published in the British Journal of Sports Medicine found that twice-weekly resistance training reduced all-cause mortality by 23% compared to no resistance training.

Preserving muscle through regular strength work:

• Supports metabolic health and insulin sensitivity
• Prevents sarcopenia (age-related muscle loss)
• Maintains functional independence
• Provides a reservoir of amino acids for immune function during illness

3. HIIT (High-Intensity Interval Training)

Short bursts of high-intensity exercise with recovery periods have been shown to trigger unique cellular adaptations that support longevity:

• Enhanced mitochondrial biogenesis (creation of new cellular power plants)
• Improved VO2 max (oxygen utilisation capacity)
• Increased production of BDNF (brain-derived neurotrophic factor) for cognitive health

4. Mobility and Balance Work

Often overlooked, these modalities become increasingly important with age:

• Prevents falls (a leading cause of disability in older adults)
• Maintains joint health and range of motion
• Supports nervous system function
• Reduces chronic pain that can limit other physical activity

The Heart Rate Recovery Metric

One powerful indicator of longevity potential is how quickly your heart rate recovers after exercise. Your heart rate recovery (HRR) provides insight into autonomic nervous system health and overall cardiovascular fitness.

For a deeper understanding of this critical biomarker, see our article on HRR: How to Boost Your Heart Rate Recovery for a Longer Life.

Supplementation: Strategic Support for Longevity Pathways

While diet and exercise form the foundation of any longevity strategy, targeted supplementation can address specific cellular mechanisms of ageing and fill nutritional gaps.

The key is focusing on evidence-backed supplements that address fundamental ageing processes rather than simply treating symptoms.

NAD+ Precursors: Restoring Cellular Energy

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells that plays a critical role in energy metabolism, DNA repair, and gene expression regulation. NAD+ levels naturally decline with age, making its restoration a primary target for longevity interventions.

NMN (Nicotinamide Mononucleotide) is as a leading NAD+ precursor, supported by research showing its ability to:

• Enhance mitochondrial function
• Support DNA repair mechanisms
• Improve metabolic flexibility
• Potentially counteract various aspects of ageing

Our NMN Supplement provides a high-quality, stable form of this powerful compound. For those wondering how this compound works within the body, our guide on How NMN Works in the Body: A Simple Guide provides clarity.

For athletes and fitness enthusiasts, NMN has shown particular promise for enhancing performance. Research indicates it may supercharge aerobic capacity, making it a valuable addition to training programmes.

Sirtuin Activators: The Longevity Genes

Sirtuins are a family of proteins that regulate cellular health, stress resistance, and longevity. Certain compounds can activate these "longevity genes":

Resveratrol, found in red wine, berries, and available as a supplement, has been shown to activate SIRT1, a key sirtuin associated with longevity benefits. Our Resveratrol supplement provides a concentrated, bioavailable form of this compound.

For maximum synergy, many longevity researchers combine NAD+ precursors with sirtuin activators. Our NMN, Resveratrol and TMG Complex offers this powerful combination in a single formula. Learn more about the benefits of this combination in our article on NMN and Resveratrol Benefits.

Mitochondrial Support: Powering Cellular Health

Mitochondria—our cellular energy powerhouses—become less efficient with age, contributing to energy decline, increased oxidative stress, and cellular dysfunction.

Key mitochondrial support supplements include:

Coenzyme Q10 (CoQ10): This vital compound is essential for mitochondrial energy production and serves as a powerful antioxidant. Our Co-Q10 Supplement (300mg) provides a highly bioavailable form of this critical nutrient.

Alpha Lipoic Acid (ALA): Both water and fat-soluble, ALA serves as a universal antioxidant and supports mitochondrial function. Our Alpha Lipoic Acid supplement harnesses these benefits in a stable, effective formulation.

For comprehensive mitochondrial support, our Mitochondrial Health Bundle combines key nutrients that work synergistically to enhance cellular energy production. You can explore our full range of mitochondrial support options in our Mitochondrial Support Supplements collection.

Foundational Minerals: The Often Overlooked Essentials

While much attention in longevity science focuses on cutting-edge compounds, basic mineral status remains critically important. Magnesium, in particular, serves as a cofactor in more than 600 enzymatic reactions and plays a vital role in DNA repair, energy production, and protein synthesis.

Our Magnesium Complex provides multiple forms of this essential mineral for optimal absorption and utilisation. For more on how this fundamental nutrient supports longevity, see our article on The Proven Benefits of Magnesium for Longevity and Healthy Ageing.

Comprehensive Approach: The Longevity Matrix

While each pillar—diet, exercise, and supplementation—offers significant benefits individually, the most profound results come from their synergistic implementation. This integrated approach creates what longevity researchers call a "hormetic effect"—where multiple mild stressors combine to create greater resilience than any single intervention.

Personalised Strategies Based on Biomarkers

One size does not fit all in longevity science. Increasingly, researchers recommend personalised approaches based on individual biomarkers and genetics.

Simple at-home assessments can provide valuable insights into your current biological age and areas for improvement. Our guide on How to Measure Your Biological Age at Home: Eight Simple Tests offers practical strategies for self-assessment.

For those interested in a more technologically advanced approach, we've recently introduced a Biological Age Calculator that integrates multiple biomarkers for a comprehensive assessment.

Gender-Specific Considerations

Research increasingly shows that longevity strategies may need to be tailored based on biological sex differences:

For men, our Longevity Supplements for Men collection addresses specific male considerations such as testosterone maintenance, prostate health, and male-pattern cardiovascular risk factors.

For women, hormonal transitions throughout life require specific nutritional support. Our Longevity Supplements for Women collection addresses these unique needs.

Emerging Factors in Longevity Science

While diet, exercise, and supplementation form the core of longevity strategies, research continues to uncover additional factors that significantly impact healthspan:

Circadian Rhythm Optimisation

The timing of activities—from eating to sleeping to exercising—profoundly affects cellular function. Disruptions to our natural circadian rhythms, like those caused by shift work or Daylight Saving Time, can accelerate cellular ageing and increase disease risk.

Even seemingly benign habits, such as when we consume our morning coffee, can impact longevity. Recent research suggests that morning coffee consumption may extend lifespan compared to afternoon or evening consumption.

Stress Management and Recovery

Chronic psychological stress triggers inflammatory cascades, accelerates telomere shortening, and disrupts cellular repair mechanisms. Effective stress management—through meditation, nature exposure, social connection, and adequate sleep—is increasingly recognised as a fundamental longevity practice.

Environmental Factors

Our external environment significantly impacts our internal biology. Exposure to air pollution, endocrine-disrupting chemicals, excessive noise, and artificial light at night all potentially accelerate ageing processes at the cellular level.
