The brand positions the product within its clean-label portfolio and says it delivers a complete amino acid profile while keeping a creamy oat texture. The drink supplies 10 g of protein per serving and 40 g per carton. Plenish frames the launch as an extension of its existing [clean protein range](https://www.trendhunter.com/trends/clean-protein-platform) and highlights everyday usability across occasions such as cereal, porridge and smoothies. The company cites UK shopper interest in increasing protein intake and rising searches for natural protein products. The product launched in selected [Tesco](https://www.trendhunter.com/trends/whites-oats) stores on 31 August and was set to be available online from 7 September with an RRP of £2.50. For consumers, the oat drink offers an accessible, plant-based route to added protein without changing eating habits. Its simple ingredient list targets shoppers seeking cleaner, familiar formats. The format aims to fit routine occasions while meeting demand for [protein-enriched plant nutrition](https://www.trendhunter.com/trends/ripple-organic-plantbased-milk).
