LOS ANGELES — Children’s snack brand Bitsy’s is introducing Bitsy’s Swish, a line of hydration and immunity drink mixes.

The products are sweetened with organic stevia and monk fruit and are fortified with vitamin C, zinc and electrolytes. Flavors include blue raspberry, pink lemonade, fruit punch and cotton candy.

“Our goal has always been to make kids’ snacks and drinks that are healthy, tasty and most importantly, accessible for all families,” said Gabrielle Union, co-founder of Bitsy’s and actor.

Prior to launching the business with Ms. Union, Bitsy’s co-founders Alex Buckley and Maggie Patton established generationOn, a federally funded after-school initiative addressing the issue of childhood obesity. The effort was recognized by the Alliance for a Healthier Generation, American Heart Association and Clinton Global Health Initiative. The experience inspired the founding of Bitsy’s, which plans to offer cookies and crackers, nutrition bars and meals for children that are nutritious and accessible to all families.

Bitsy’s Swish is available for $4.98 per six-count box at more than 3,500 Walmart stores nationwide.
