Danone Expands Silk Protein Line to Compete with Dairy Products

Current trends indicate that protein consumption extends beyond sports-focused diets, while plant-based purchases are increasingly popular among non-vegetarian consumers. Goodwin highlighted that Danone views this convergence as an opportunity to transition Silk from merely a dairy alternative to a comprehensive functional nutrition brand. She noted, "Danone sees a significant opportunity for plant-based products at the intersection of two converging trends: increasing interest in food and beverages that deliver functional, nutrient-dense benefits and growing consumer demand for protein."

Silk recently expanded from its base in refrigerated milk into plant-based yogurt and shelf-stable ready-to-drink (RTD) shakes, offering products suited for breakfast, snacking, and on-the-go consumption. Silk Protein Milk, which launched in January 2026, includes 13 grams of complete plant protein, 3 grams of fiber, and 50% less sugar than conventional dairy milk, positioning it as the highest-protein refrigerated plant-based milk on the US market. The new Silk Protein Shakes contain 30 grams of protein per serving and 5 grams of fiber, while Silk Protein Yogurt provides at least 12 grams of complete plant protein and 4 grams of fiber along with essential nutrients like calcium and vitamin D.

Goodwin remarked on the persistent consumer demand for protein, citing data that indicates 70% of Americans are trying to increase their protein intake, whereas plant-based sources constitute only about one-third of total protein consumption. At Danone, there is a clear intent to bridge this gap by providing plant-based options that deliver both nutrition and taste. She concluded that the company's extensive portfolio is aimed at meeting varied nutritional needs, which have often been underserved within the grocery sector.

Innova Market Insights identified the “Powerhouse Protein” trend as a significant focus for 2026, with nearly 60% of consumers globally aiming to increase their protein consumption; milk and dairy products remain the leading category for protein claims. Goodwin observed that the Silk brand's offerings, which combine protein with fiber and lower sugar content, align with consumer preferences for products that deliver multiple benefits.

Amid increasing interest in digestive health, brands are responding by integrating fiber and other functional benefits into protein-rich offerings. Innova's research shows that fiber has become a prominent consideration, with a majority of US consumers expressing an interest in its functional attributes. Goodwin acknowledged the importance of balancing nutritional benefits with taste and marketability for manufacturers.

While 60% of US households purchased plant-based foods in 2025, some consumers may still have misconceptions about the category's breadth. Danone's strategy involves positioning its plant-based products alongside traditional dairy products rather than promoting them as separate entities. Goodwin pointed out, "When Silk first entered grocery stores decades ago, it was the first plant-based brand to place soy milk alongside dairy on a national scale."

Recent feedback shows that about half of consumers switching to Silk Protein are coming from dairy, reinforcing its competitive profile. This shift is crucial for retailers, as new category growth relies on attracting customers beyond the existing plant-based consumer base. Danone's sales teams utilize retailer insights and shopper data to refine product placements and optimize space allocation.

Goodwin emphasized the ongoing efforts to enhance distribution and visibility, noting that the early success of the Silk Protein line indicates its potential to attract new consumers to the plant-based segment. While nutritional benefits play a significant role in purchase decisions, taste remains essential for ongoing consumer loyalty. Data indicates that 50% of consumers desire better taste in plant-based products.

Goodwin claims that as the leading plant-based beverage brand endorsed by registered dietitians, Silk is well-positioned to innovate within the plant-based category by offering products that effectively combine flavor, convenience, and essential nutrients. Looking forward, the company aims to evolve away from imitation products towards options that emphasize real nutritional value.

In line with this strategic direction, Danone's planned €1 billion (US$1.14 billion) acquisition of Huel reinforces its focus on mainstream functional nutrition and convenient, high-protein products.
