Isopure is best recognized for its whey protein isolate products, designed to use only essential ingredients. The range includes Whey Protein, providing 25 grams of protein from whey protein isolate, and Collagen, made with Type 1 collagen and vitamin C to support healthy skin and joints.
The products are now available through retailers including Holland & Barrett, Boots UK, Amazon, Sainsbury’s and Ocado Retail.
Josi Robson, head of healthy lifestyle brands at Glanbia Performance Nutrition, said that the expansion into the UK was a “natural next step following its long-standing success in the United States.”
Glanbia acquired the U.S. sports nutrition firm The Isopure Company for US$ 153 million (£94.1M) in 2014 in a move to strengthen its Global Performance Nutrition portfolio.
The Isopure brand is one of several in the performance nutrition range, which also includes Think!, Amazing Grass and the well-known Optimum Nutrition, which, according to Glanbia’s Half Year financial report published in August 2025, makes up 67% of total sales.
Demand for clean-label products
“UK consumers are increasingly looking for simplicity and quality in their nutrition choices—values that sit at the heart of Isopure,” Robson told NutraIngredients. “Our products are built around a ‘less is more’ philosophy.”
According to a recent Mintel report, clean label emerged as one of the main trending topics in sports nutrition in 2024.
The report stated: “The clean label movement is having an impact on the sports nutrition industry, as consumers are increasingly favoring a simple ingredients list on the products they buy. There is a strong consumer interest in natural sports nutrition products that align with a ‘clean label’ image.”
Robson affirmed this, noting there is a “clear demand in the market for products with minimal and recognizable ingredients—formulations that provide quality nutrition without unnecessary additives.”
As part of the launch, Glanbia is taking a ‘multi-channel’ marketing approach, using digital platforms, influencer partnerships and in-store retail experiences to connect with consumers.
This included partnering with a select group of fitness and health influencers including Daisy Reed (head of social, SheerLuxe), Millie McIntosh (lifestyle influencer), Sinead Crowe (content creator) and Jessica Avey (wellness influencer).
Collagen and protein powder trends
Robson said the Isopure launch in the UK comes at a time when protein and collagen are increasingly used to support overall wel-lbeing and active lifestyles.
Social media has become a driving force behind key nutrition trends, changing how people approach health and wellness.
A recent YouGov survey of over 2,000 adults in the UK revealed that 27% of 18- to 24-year-olds, and 37% of 25- to 34-year-olds regularly drink protein shakes. Furthermore, the UK collagen market was valued at US$ 623.18 million in 2025 and is projected to climb to US$ 854.61 million by 2030, according to insights from Mordor Intelligence.
“As the brand grows, we’ll assess opportunities to expand the range or introduce new formats that meet evolving consumer needs,” Robson said.
