Editor quote: “Since I often have a tough time shutting off my mind at night — especially after a stressful day — I decided to mix myself the first glass of Natural Vitality Calm about an hour before going to bed. I could already feel my body start to relax as I sipped the drink while reading a book, and by the time I turned off the lights, I was completely ready to sleep. When I’m especially busy, I often have stress dreams about something I need to accomplish at work the next day or wake up in the middle of the night thinking about emails. After drinking Natural Vitality Calm, I slept right through the night — without feelings of stress or latent worries.” — Annalise Mantz, associate director, Branded Content
