Our Snacks That Relax box is specifically designed to help with stress and insomnia. The snacks have potassium, magnesium, beta-glucan, antioxidants, and polyphenols, which are scientifically proven to help these issues. For a one-time purchase, we offer three box sizes, small, medium, and large. Small boxes are intended to last a week for one person, a medium is for two people, and the large box will last three people a week. Want to subscribe and get enough snacks for the month? You can do that too! Our subscription service comes with a medium box bi-monthly subscription. You can buy the subscription separately each month, or buy the subscription for the entire year up front (which saves you $50!)
