Human studies show NR reliably and safely raises NAD+ levels, supporting mitochondrial function, neuroprotection, and anti-inflammatory pathways
non-supplemented baseline Before: 145 lbs, 28% body fat, active trainer, strong metabolic baseline Protocol: 300 kcal deficit, 1.8g protein/kg, 2g L-carnitine daily, 4 resistance + 3 cardio sessions weekly After: 135 lbs, 22% body fat (10 lbs loss, ~9 lbs fat + 1 lb muscle), visible abdominal and shoulder definition Result: L-carnitine + training allowed aggressive deficit while preserving strength
A problem at any part along the way can impact the bioavailability of vitamin B12
Brain & Nervous System Function B12 is critical for maintaining the myelin sheath that protects nerve fibers, supporting cognitive function, memory, and neurological health
Standard oral glutathione has a real bioavailability problem: stomach acid and gut enzymes break the molecule apart before much of it reaches your bloodstream intact
