Sound sparkling water
The company Sound infuses sparkling water with a variety of organic teas, herbs, and fruit extracts to create unique flavor combinations.
These drinks are free of calories, sweeteners, and artificial ingredients. The green and black tea varieties contain 45 mg of caffeine per 12-ounce (355-mL) can, while the ginger and hibiscus tea flavors are caffeine-free.
Though Sound’s products haven’t been studied specifically, green and black teas are linked to a host of health benefits due to their high concentration of plant compounds called flavonoids.
For example, multiple human studies associate green tea with a reduced risk of heart disease.
