A winning formula built on trust


Quality, efficacy and safety are the measure of our integrity

For more than 30 years, the infant formula industry has placed its trust in Carbery to supply ingredients that precisely meet international standards of quality, efficacy and safety. Our integrity as a whey-based ingredients supplier is reflected in our long-term supply relationships and our ongoing research and development partnerships with some of the world’s most successful infant formula companies.

Trust and traceability – your natural advantage

Carbery’s commitment to quality begins at source. Our unique location on Ireland’s south-western seaboard is the perfect environment for sustainable dairy farming. It’s from here our farmer-owners supply the highest quality milk from grass fed dairy herds. Complete control of our supply chain means complete supply chain visibility and traceability. Beyond the farm gate, innovative, sustainable and efficient processing to ISO 9001:2015 standards secures the nutritional value of this high quality milk.

Every infant nutrition formulation includes carefully defined energy and macro-nutrients to suit different development ages. Our processing quality and hygiene systems work to consistently meet these stringent nutritional and microbiological specifications.

As a customer, you benefit from our unique combination of sustainable dairy, uncompromising quality, professional integrity, extensive R&D and pioneering research.

Advanced whey proteins

We produce a specific range of whey proteins for infant formula. Our custom nutritional solutions include targeted molecular weight profiles, specific mineral compositions and microbiologial profiles.

Our expertise is in the development of partially hydrolysed whey proteins for comfort infant formula under our Optipep® portfolio. Whey protein hydrolysates are easier to digest and absorb than intact proteins and can enhance digestive comfort in formula-fed infants. Carbery’s proprietary hydrolysis technology has the capacity to target specific and unique hydrolysate characteristics.

We supply Kosher and Halal whey proteins for both dry and wet mix processes.

Innovating for the next generation

We are actively advancing research that will enable our customers to enhance the role of maternal nutrition and the early days of an infant’s life. This fundamental research is wide ranging and includes a focus on  specialised nutritional formulae.

We identify, characterise and compare relevant compositions and bioactive fractions in milk to discover nutritional benefits most suited to specialised formulations. Our unique disciplinary approach to milk mining leverages the expertise of paediatricians, food scientists, microbiologists and immunologists within our Food for Health Ireland research partnership.

We are relentless in our pursuit of new functionality and better understanding the mode of action of dairy-based ingredients which; enhance nutrient absorption, gut microbiology, immune protection, manage inflammatory disorders and milk allergies – for next generation infant formulae.

Here is an introduction to our ingredient brands:

Optipep, our innovative range for specialised nutritional applications includes hydrolysed whey protein isolates (90% protein) and hydrolysed whey protein concentrates (80% protein). Targeted hydrolysis enzymatically digests the native proteins into smaller fractions and peptides. These are rapidly digested and absorbed delivering essential protein nutrients for growth and maintenance of muscle mass. Learn more about Optipep® Infant and Optipep® Sports.


The Optipep production process

Isolac, our whey protein isolate range, for use in performance nutrition, infant formulae, dietetic products and clinical nutrition, are high in protein (90%), low in fat and lactose. We use cross flow micro-filtration technology, a natural process that removes fat and lactose while concentrating the valuable whey protein fractions. Read more about Isolac here.>


Carbelac, our high quality whey protein concentrates offer great versatility across a wide range of food and beverages due to its functional (texture and mouthfeel enhancement) and nutritional (higher protein) benefits. Through ultrafiltration, we target premium concentrates with 35-80% protein. Read more about Carbelac here.>


Carbery recognise that infant formula is second to breastfeeding, in line with the World Health Organisation (WHO) recommendations.
