Plenish has introduced Protein Oat Drink, a high-protein oat beverage made with four ingredients and without oils or additives, designed to boost daily protein intake. 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 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 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.

What Makes This Trend Stand Out
- Protein-enriched Plant Milks
- Everyday dairy alternatives are evolving into functional nutrition platforms, creating whitespace for clean, high-protein beverages that fit existing consumption rituals.
- Clean-label Functional Drinks
- Minimal ingredient formulations are reshaping the functional beverage category as shoppers seek performance benefits without oils, additives or unfamiliar components.
- Routine-based Nutrition
- Protein fortification in familiar formats such as cereal, porridge and smoothies reflects demand for health upgrades that require little behavioral change.
Sectors Adopting This
- Plant-based Beverages
- The category is expanding beyond dairy replacement into targeted wellness benefits, opening opportunities for differentiated products built around protein, texture and simplicity.
- Functional Foods
- Complete amino acid claims in accessible oat formats signal a broader shift toward mainstream products that combine convenience with measurable nutritional value.
- Grocery Retail
- Supermarket launches of clean protein drinks show how retailers can capture health-driven shoppers through affordable, familiar and shelf-ready plant-based innovations.
