Source Naturals Sleep Science offers a liquid melatonin product with a 1.0mg dose, which is often recommended as an ideal starting point by nutritionists for its gentle effectiveness and minimal risk of side effects. The liquid form is a significant advantage, allowing for highly precise dosing (e.g., half a serving for 0.5mg, or more for higher needs) and faster absorption compared to pills. This versatility makes it suitable for individuals of all ages (with medical consultation for children) and for addressing various sleep issues, from mild sleeplessness to jet lag. Its competitive price per serving adds to its value.
