• Best Time to Take: Morning (aligns with NAD+ circadian rhythm)
• Optimum Dose: 250-500 mg/day
• Long-Term Safety: Appears safe based on current research; long-term data limited due to novelty
• Interactions: May enhance effects of other B vitamins; avoid with alcohol (competes with NAD+ pathways)
• Purpose: Increases NAD+ levels, critical for mitochondrial energy production and repair

5. Resveratrol

• Type: Polyphenol (plant-derived antioxidant)
• Major Variants: Trans-Resveratrol (active form), found in grapes, red wine, supplements
• Half-Life: Approximately 2-4 hours (short, benefits from sustained-release forms)
• Best Time to Take: Evening (mimics calorie restriction effects, aligns with sirtuin activation)
• Optimum Dose: 150-500 mg/day
• Long-Term Safety: Generally safe; high doses (>1,000 mg) may cause GI distress
• Interactions: May inhibit cytochrome P450 enzymes, affecting drug metabolism (e.g., warfarin, statins)
• Purpose: Activates sirtuins, promotes mitochondrial biogenesis, and reduces oxidative stress

6. PQQ (Pyrroloquinoline Quinone)

• Type: Vitamin-like compound
• Major Variants: BioPQQ (natural form), synthetic PQQ
• Half-Life: Approximately 3-5 hours
• Best Time to Take: Morning (supports energy production)
• Optimum Dose: 10-20 mg/day
• Long-Term Safety: Appears safe at recommended doses; limited long-term human data
• Interactions: Synergistic with CoQ10; no major adverse interactions reported
• Purpose: Stimulates mitochondrial biogenesis, protects against oxidative damage

7. Magnesium

• Type: Mineral
• Major Variants: Magnesium citrate, glycinate, threonate (varies in bioavailability)
• Half-Life: Approximately 24-48 hours (depends on body stores and excretion)
• Best Time to Take: Evening (supports relaxation, ATP synthesis)
• Optimum Dose: 300-400 mg/day (elemental magnesium)
• Long-Term Safety: Safe at recommended doses; excess may cause diarrhea
• Interactions: May reduce absorption of bisphosphonates or antibiotics; enhances B vitamins’ effects
• Purpose: Cofactor in ATP production, stabilizes mitochondrial membranes

8. Creatine

• Type: Amino acid derivative
• Major Variants: Creatine monohydrate (most studied), creatine HCL
• Half-Life: Approximately 3 hours (as creatine in plasma)
• Best Time to Take: Post-workout or anytime (with food for absorption)
• Optimum Dose: 3-5 g/day (maintenance); 20 g/day (loading phase, split doses)
• Long-Term Safety: Safe for long-term use; rare kidney strain in high doses with pre-existing issues
• Interactions: No significant interactions; pairs well with carbohydrates for uptake
• Purpose: Boosts phosphocreatine stores, enhances mitochondrial energy buffering

9. Omega-3 Fatty Acids

• Type: Essential fatty acids
• Major Variants: EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), ALA (plant-based precursor)
• Half-Life: Days to weeks (stored in cell membranes)
• Best Time to Take: With meals (fat-soluble, improves absorption)
• Optimum Dose: 1,000-2,000 mg/day (combined EPA/DHA)

Notes

• Half-Life: Exact values depend on formulation (e.g., sustained-release vs. standard) and individual metabolism; estimates are based on typical pharmacokinetics.

• Safety and Interactions: Long-term safety data is robust for established supplements (e.g., CoQ10, magnesium) but limited for newer ones (e.g., NR, PQQ). Always consult a healthcare provider, especially if on medications.

• Dosing: Optimal doses vary by individual needs and health goals; these are general guidelines supported by research and clinical practice.

This list reflects supplements with strong evidence or consensus for mitochondrial support, balancing efficacy, safety, and practicality.
