Is It Safe to Take Melatonin Every Night?

Taking melatonin every night is generally safe for short-term use, but long-term daily use requires careful consideration. The American Academy of Sleep Medicine notes that melatonin is well-tolerated for periods up to 3 months in most adults. However, your body naturally produces melatonin, and regular supplementation may affect this natural production over time. Common side effects include morning grogginess, headaches, and vivid dreams. The optimal dose ranges from 0.5-3mg taken 1-2 hours before bedtime. Consult your healthcare provider before starting nightly melatonin use, especially if you take other medications or have underlying health conditions, as melatonin can interact with blood thinners and diabetes medications.
