How to Take It
Best taken in the evening
Take 30–60 minutes before bed. It's a circadian signal, not a daytime supplement. Vitamin B6 is easier on the stomach taken with food.
With food
On the label
1 to 3 sprays before bedtime. Each spray delivers approx. 1.5 mg of melatonin. For best results, allow liquid to remain in the mouth for 30 seconds and swish before swallowing.
General guidance based on the ingredients, not a substitute for the label or your doctor.
