Mechanistic highlights
- NAD+ Precursor Activity: Trigonelline acts as a novel NAD+ precursor, enhancing cellular energy metabolism and mitochondrial function through NAD+-dependent pathways
- Anti-inflammatory Action: Reduces pro-inflammatory cytokines (TNF-α, IL-6) in neural tissues and systemic circulation
- Neuroprotection: Normalizes neurotransmitters (dopamine, noradrenaline, serotonin) in the hippocampus, supporting cognitive function
- Metabolic Regulation: Enhances β-cell function, improves insulin sensitivity, and modulates glucose/lipid metabolism enzymes
- Antioxidant Defense: Activates Nrf2 pathway, reduces oxidative stress markers, and protects against cellular damage
Safety & practical use
- Usual supplemental range: 100-500mg/day (based on coffee consumption providing 50-300mg daily)
- Upper-dose tolerance: Well-tolerated up to 1g/day; no adverse effects reported in animal studies up to 10mg/kg
- Drug interactions: May enhance effects of antidiabetic medications; monitor blood glucose if diabetic
- Natural dietary sources: Coffee (50-300mg/cup), fenugreek seeds, peas, oats
- Populations needing medical oversight: Diabetics on medication, pregnant/nursing women (limited safety data)
- Storage: Keep in airtight container away from moisture; hygroscopic compound
