Just senior consultant Katy Sparks will head up the account for the brand.
The campaign will be focused on UK healthcare professionals and consumers and will include development of educational materials targeting the over 55s who have been diagnosed with high cholesterol.
Emmi UK marketing director Stephen Kimber said: ‘We believe there is a real opportunity for the brand, by broadening our communications to healthcare professionals as well as our target consumers.'
Sparks said: ‘Functional foods are playing an increasingly important role in supporting self-management of health conditions. We see this as a strong area for growth for Just, and we will be looking at this as we continue to strengthen our consumer health client base in 2010.'
In 2009, Just supported a number of consumer-focused campaigns, including OTC hayfever brand Clarityn on behalf of Schering Plough.
Joint MDs Emma Crozier and Jennie Talman founded the agency in February 2006. Just currently employs 24 staff, having added six consultants to the team in 2009.
