Healthcare providers may recommend an initial treatment period of 4-6 weeks with 1-3 doses per week [21]
NAD+/NADH ratio assays, SIRT1 activity assays, and mitochondrial respiration measurements (such as oxygen consumption rate via extracellular flux analysis) are standard methods for studying this combination's proposed effects in cell-based models, typically comparing single-compound and combined-compound treatment conditions against untreated controls
Levels decline naturally with age, and that decline is tied to fatigue, cognitive decline, muscle loss, neurodegeneration, and metabolic disease
If you are mildly B12 deficient but are otherwise in good health, you may be able to raise your B12 levels with a few simple dietary adjustments
