CalmEZ Brain Tonic was developed by a family of physicians from Vietnam for mood boost, brain function, calming, and sleep. The formula originates from a unique application of Oriental medicine used over several generations. Utilizing herbal extracts from traditional Chinese medicine (TCM) in a novel combination, CalmEZ provides support for deep sleep, while also supporting the major organs involved with the feeling of refreshment in the morning, the liver and the heart. CalmEZ also supports increased circulation in the brain, and can be used during the day for calming and mood enhancement.
