On the label
For occasional sleep support,* start with half a teaspoon of Natural Vitality CALM® Sleep Drink Mix, gradually increasing to two leveled teaspoons as needed. Place powder into a cup or mug, add 2-3 ounces of warm water and let your drink fizz. Stir the drink until the powder is completely dissolved, then fill the remainder of the cup with warm or cold water. Enjoy before bedtime and experience CALM.
General guidance based on the ingredients, not a substitute for the label or your doctor.
