Melatonin 20mg 90 veg caps

Taking 20mg of melatonin provides a strong dose to promote sleep by regulating the sleep cycle, but it's often considered very high and can lead to side effects like headaches, dizziness, grogginess, nausea, or irritability, with lower doses (1-5mg) typically recommended for general use; this high dose is best used cautiously, under guidance, for severe issues like jet lag or shift work, not routinely.
