Translating a product from one that's warm and savoury to one that's ambient and sweet takes courage. The former is how consumers see it now. The latter is beyond the consumer imagination. It's a move that's either the brilliant reinvention of a category or something that consumers will see as too weird.

Bone broth is one of the growth stories in the American supermarket. Retail sales of broth grew rapidly from about 2020, passing $400 million in 2025. The Kettle & Fire brand is the market leader and can take much of the credit for the surge of interest in bone broth.

Comforting, consumed from a cup or bowl, and these days available in cartons, concentrates and powders, bone broth is a traditional food reinvented, associated with a range of benefits from skin health to digestion.

Now US-based brand Marro is trying to get people to think differently about broth, essentially reinventing the traditionally hot, savoury “soup” as “the first cold, sparkling, ready-to-drink bone broth beverage”. Headquartered in Georgia, Marro was created by Nick Foreste, an ultramarathon runner, who in a media interview described his motivation as wanting “the recovery and wellness benefits of bone broth without feeling like I had to drink soup”.

The product is made with water and concentrated beef broth. Each 355 ml (12 oz) can delivers 12g of protein from bone broth, plus electrolytes and vitamin B12. Sweetened with stevia, it has 0g of sugar. Flavours position it very clearly as a fruit soda: Blueberry Lemonade, Blackberry Lime, and Peach Mango. It’s positioned around benefits spanning hydration, gut health, muscle recovery, skin/hair/nail health and immune health.

Recently launched, it’s sold through Marro's own website and Amazon.
