Understanding Mitochondria
Mitochondria are the powerhouses of your cells β they produce ATP (energy) through oxidative phosphorylation. You have approximately 10 million billion mitochondria in your body.
Mitochondrial decline is a hallmark of aging:
- Reduced ATP production
- Increased oxidative stress
- Accumulation of damaged mitochondria
- Reduced mitochondrial biogenesis
1. CoQ10 (Ubiquinol) β Best Overall
Why: Essential component of the electron transport chain (Complex III). Without CoQ10, mitochondria cannot produce ATP efficiently.
Clinical Evidence:
- Mortensen et al. (2014): 300mg/day for 2 years reduced cardiovascular events by 43% in heart failure patients.
- Rosenfeldt et al. (2007): Improved cardiac function and exercise capacity.
Effective Dose: 100-400mg/day (ubiquinol form)
2. PQQ β Best for Mitochondrial Biogenesis
Why: PQQ (pyrroloquinoline quinone) stimulates the creation of new mitochondria via PGC-1Ξ± activation.
Clinical Evidence:
- Harris et al. (2013): PQQ (20mg/day) improved cognitive function.
- Ito et al. (2016): PQQ increased mitochondrial biogenesis markers. ,/ul>
- Ziegler et al. (2006): ALA (600mg/day) improved insulin sensitivity and reduced oxidative stress.
- Packer et al. (2001): ALA protected mitochondria from free radical damage.
- Montgomery et al. (2003): ALCAR (2g/day) improved cognitive function in elderly.
- Malaguarnera et al. (2008): ALCAR improved fatigue and cognitive function.
- Yi et al. (2023): NMN (500mg/day) increased NAD+ by 40-90%.
- Martens et al. (2018): NR (1,000mg/day) increased NAD+ by 60%.

Effective Dose: 10-20mg/day
3. Alpha-Lipoic Acid β Best Antioxidant
Why: Potent antioxidant that protects mitochondria from oxidative damage. Also supports glucose metabolism.
Clinical Evidence:
Effective Dose: 300-600mg/day (R-form preferred)
4. Acetyl-L-Carnitine β Best for Transport
Why: Transports fatty acids into mitochondria for energy production. Also supports brain function.
Clinical Evidence:
Effective Dose: 1,000-2,000mg/day
5. NMN / NR β Best for NAD+ Support
Why: NAD+ is essential for mitochondrial electron transport. Levels decline with age.
Clinical Evidence:
Effective Dose: NMN 500-1,000mg or NR 500-1,000mg/day
The Mitochondrial Stack
Morning: CoQ10 200mg + PQQ 20mg + ALA 300mg + NMN 500mg Evening: ALCAR 1,000mg + CoQ10 100mg
The Bottom Line
For mitochondrial health: CoQ10 (200-400mg) + PQQ (10-20mg) + ALA (300-600mg) + ALCAR (1,000-2,000mg) + NMN (500mg). This stack addresses energy production, biogenesis, antioxidant protection, and NAD+ support.
