Additional Information

Many people do not get enough sleep during the night. As a result, waking up in the middle of the night and moving in bed back and forth is very energy-consuming not being able to sleep. Our body needs to rest to perform better the next day with all the activities during our day and work.

Our SLEEP products come in different potencies as SLEEP 1, SLEEP 3, SLEEP 5, SLEEP 10, SLEEP 12, SLEEP 15, SLEEP 20, SLEEP 30, SLEEP 40, SLEEP 50, SLEEP 60. This is the mg of Melatonin it has per capsule since everyone requires different potencies.
