Tart cherry juice is a great ingredient to add to your toolkit when you're looking for food to support your immune system. It's believed to contain melatonin, which helps control your sleep-wake cycle. And we all know that when we get more sleep, we decrease our stress levels and help our immune system work properly.

So try this delicious and fizzy mocktail from TJ Collins. Drink it as a nightcap before you go to bed or as a refreshing afternoon treat.

1/4 cup tart cherry juice
1 cup orange juice
1 sprig of rosemary
Splash of plain seltzer

Sir all the ingredients — except the seltzer — together in a pitcher with ice. Pour into your favorite glass and top with a splash of seltzer.
