About Melatonin
Pineal-gland hormone that signals 'night-time' to the body. Most useful for jet lag and shifted sleep schedules; lower doses (0.3 mg) often work better than 5–10 mg.
About Taurine
Calming amino acid that supports cardiovascular function and mitigates caffeine jitters. Recent research links it to extended healthspan.
