Danone North America has expanded its Silk portfolio with the introduction of a new multi-serve beverage containing plant-based protein.

A source of calcium, Silk Ultra is available in creamy chocolate, unsweet and original flavours, and can be enjoyed straight out of the carton, in a smoothie or over cereal.

The brand says that the beverage is geared towards athletes and offers 20g of complete plant-based protein per serving. Silk Ultra is also a source of vitamins A, D, B2 and B12.

“Fitness enthusiasts know that protein plays a critical role in supporting muscle performance, and serious athletes are incorporating more plant-based options into their diets and training regimens,” said Andrew Hartshorn, senior vice president, plant-based food and beverages for Silk.

“As the experts in developing delicious plant-based beverages for over 30 years, Silk saw a real consumer need for a great-tasting plant-based beverage in the protein space. Silk Ultra delivers complete plant-based protein and truly delicious taste, so athletes don’t have to compromise.”

Silk Ultra is available in multi-serve cartons, for an MSRP of $4.99 per 59oz product, from grocery stores nationwide in the US.

Last year, Danone North America added to its Silk portfolio with a new range of Almondmilk Mix-Ins Yogurt Alternatives.
