Protocol For Life Balance's PQQ Complex is formulated with four key ingredients known for their roles in cellular energy production and neurological health: Acetyl-L-Carnitine (200mg), BioPQQ (20mg), Coenzyme Q10 (30mg), and Vitamin B12 (1000mcg as Methylcobalamin). This combination aims to support mitochondrial function, which is central to brain health, energy, and metabolism. The inclusion of PQQ and CoQ10 specifically targets mitochondrial biogenesis and ATP production, while ALCAR supports fatty acid transport for energy and neurotransmitter synthesis. Vitamin B12 is crucial for nerve function and energy metabolism. Online reviews and nutritionist perspectives generally support the benefits of these individual ingredients for the advertised goals, though some experts might recommend higher dosages for certain conditions or for more pronounced effects, particularly for ALCAR and CoQ10. The forms used (Acetyl-L-Carnitine HCl, PQQ Disodium Salt, Methylcobalamin) are well-regarded for bioavailability.
