Gastrointestinal side effects are the most common adverse events, which usually occur during the dose escalation period and then decrease over time
[7] [8] Oral NAD+ precursors (NR or nicotinamide) generally produce milder side effects, most commonly mild gastrointestinal upset, including nausea, diarrhoea, or indigestion
The latest research further confirms that taVNS slows gastric motility by inducing vagal efferent impulses, highlighting it regulates appetite through the dorsal vagal complex [54]
They work to help the body use macronutrients (carbohydrates, fat and protein) for fuel and also play an important role in brain function and DNA production
Conclusion In summary, our study provides an integrated and functionally validated characterization of metabolic remodeling during early NGN2-mediated neuronal differentiation
