Melatonin Benefits
- ✓Sleep regulation, circadian rhythm restoration, antioxidant protection, immune system support, potential neuroprotection, anti-aging effects
Spermidine Benefits
- ✓autophagy induction
- ✓mitochondrial quality control
- ✓cardiometabolic support
- ✓healthspan association
Melatonin Dosing
0.5-10mg orally, typically 30-60 minutes before desired sleep time. Lower doses (0.5-3mg) often more effective for sleep onset
Spermidine Dosing
1-6 mg/day oral|daily supplementation protocols|dietary intake from food sources
Melatonin Side Effects
- ⚠Drowsiness, headache, dizziness, nausea, vivid dreams, potential hormone interactions, daytime fatigue with higher doses
Spermidine Side Effects
- ⚠GI upset
- ⚠bloating
- ⚠nausea
- ⚠odor changes
Research Overview
Melatonin
Melatonin has extensive clinical research supporting its efficacy for sleep disorders, jet lag, and shift work sleep disorder. Emerging research investigates its potential anti-aging, neuroprotective, and immune-modulating properties with promising preliminary results.
Spermidine
Spermidine has meaningful preclinical support and a growing human observational literature linking intake with healthier aging metrics. Its core longevity mechanism is thought to involve autophagy and improved proteostasis.
