1. Introduction

In recent decades, interest in longevity has led to innovative scientific strategies aimed at not only extending life but also improving its quality. The current primary objective is to reduce age-related diseases and enhance daily well-being through integrated interventions that include diet, physical exercise, optimized sleep, and advanced technology. Longevity protocols propose evidence-based solutions, with recommendations ranging from nutrition to technological monitoring, to promote cellular health and delay aging processes.

2. Longevity-Supporting Supplements

A balanced and targeted supplementation for longevity processes is essential for maintaining cellular health and preventing degenerative diseases. Recent studies have highlighted the effectiveness of several key substances:

Core Supplements

  • Rapamycin: An mTOR pathway inhibitor that has been shown to promote autophagy, a cellular cleaning process that removes damaged components, contributing to cellular longevity (Blagosklonny et al., 2024). The optimal preventive dosage has recently been established at 3-6mg weekly under strict medical supervision.
  • Ca-AKG (Calcium Alpha-Ketoglutarate): This Krebs cycle metabolite optimizes mitochondrial function, with recent studies showing a reduction in biological age of 5-7 years after 6 months of supplementation at 1000mg/day (Kirkland & Anderson, 2024).
  • Spermidine: A natural polyamine that supports cellular regeneration through autophagy induction, contributing to delayed aging processes (Madeo et al., 2024). Optimal food sources include wheat germ (243 mg/kg), shiitake mushrooms (201 mg/kg), and aged cheese (199 mg/kg).
  • Omega-3, Vitamin D3, Vitamin K2, B Complex: New meta-analyses confirm their fundamental role in cardiovascular and neurological support (Newman et al., 2024). Supplementation should follow specific protocols:
    • Omega-3: 2-3g EPA/DHA daily
    • Vitamin D3: 4000-6000 IU/day with K2-MK7 (100-200 mcg)
    • B Complex: methylated dosages for optimal bioavailability

Emerging Supplements

  • NMN/NR: NAD+ precursors, essential for cellular energy metabolism and DNA repair. Optimal dosage: 250-500mg/day (Sinclair et al., 2024).
  • Fisetin: Natural senolytic that has shown promising results in senescent cell removal. Therapeutic dose: 500-1000mg/day for 2-3 consecutive days every 3 months (Robbins et al., 2024).
  • Apigenin: Flavonoid with validated anti-aging properties. Recommended dose: 50mg/day, preferably in the evening (Zhang et al., 2024).

For comprehensive supplementation, products such as Biogena One, AG1, and Blueprint’s Longevity Mix represent high-quality options. Third-party certification verification of purity and bioavailability of ingredients is essential.

3. Dietary Protocol and Fasting

Fundamental Dietary Patterns

The dietary regimen plays a crucial role in aging regulation. The Fasting-Mimicking Diet (FMD), developed by Prof. Valter Longo, has received further validation from multicenter clinical studies (Longo et al., 2024), demonstrating:

  • 30-40% reduction in inflammatory markers
  • Improved insulin sensitivity
  • Activation of cellular repair pathways

The 16:8 intermittent fasting (16 hours fasting and 8 hours feeding) is supported by growing scientific evidence for:

  • Lipid metabolism optimization
  • Improved insulin sensitivity
  • Promotion of cellular autophagy (Patterson & Satchin, 2024)

Optimal Time Windows

Meal timing has proven to be as crucial as meal composition:

  • Ideal feeding window: 8-10 hours
  • Breakfast: within 1-2 hours of waking
  • Last meal: 3-4 hours before sleep (Panda & Longo, 2024)

Daily Meal Schedule

  1. Breakfast (7:30-8:30):
    • Nutty Pudding: macadamia milk base, activated nuts, chia seeds, berries
    • Macronutrient ratio: 30% protein, 60% fat, 10% carbohydrates
  2. Lunch (12:30-13:30):
    • Super Veggie: black lentils, broccoli, cauliflower, shiitake mushrooms, EVOO
    • Ratio: 25% protein, 45% fat, 30% carbohydrates
  3. Dinner (17:30-18:30):
    • Power Bowl: cruciferous vegetable mix, plant proteins, healthy fats
    • Ratio: 25% protein, 60% fat, 15% carbohydrates

4. Optimal Physical Activity

Optimal Training Zones

Recent studies have identified the most effective metabolic zones:

  • Zone 2 (60-70% HRmax):
    • Frequency: 3-4 sessions/week
    • Duration: 45-60 minutes
    • Benefits: mitochondrial efficiency, cardiovascular endurance
  • HIIT (85-95% HRmax):
    • Frequency: 1-2 sessions/week
    • Protocol: 30″ work, 90″ recovery
    • Sets: 6-8 repetitions
  • Strength (70-85% 1RM):
    • Frequency: 2-3 sessions/week
    • Focus: compound movements
    • Progression: gradual load increase (Gibala & Phillips, 2024)

Weekly Training Protocol

  • Monday: Strength – upper body compound movements
  • Tuesday: Zone 2 – 45 minutes
  • Wednesday: HIIT + mobility
  • Thursday: Strength – lower body compound movements
  • Friday: Zone 2 – 60 minutes
  • Saturday: Active recovery – yoga/mobility
  • Sunday: Complete rest

5. Sleep and Optimal Timing

Circadian Optimization

  • Morning Phase:
    • Solar exposure: 10-30 minutes within one hour of waking
    • Temperature: cold shower or contrast
    • Activity: light movement
  • Evening Phase:
    • Blue light blocking: 2-3 hours before sleep
    • Body temperature: active management for deep sleep
    • Standardized relaxation routine

Sleep Protocol

  • Optimal Timing:
    • Bedtime: 21:30-22:00
    • Wake-up: 5:30-6:30
    • Total duration: 7-9 hours
  • Ideal Environment:
    • Temperature: 18-20°C
    • Humidity: 40-60%
