Supermarket shelves across Ireland are filling with high-protein versions of everyday foods, carrying an average price markup of 31% despite nutrition data showing that the average adult already exceeds daily protein requirements. Food brands are capitalizing on a surge in demand driven by fitness influencers and marketing campaigns that frame added protein as an inherent health benefit.
The Cost of Added Protein in Irish Supermarkets
A recent market comparison of 10 everyday products in Ireland—ranging from cheese and milk to pancakes and flapjacks—revealed that shoppers pay significantly more for items sporting a protein label. The most extreme price hike appeared on Müller rice vanilla pots at SuperValu, where the protein version carried a 74% markup at €2.19 per pot. Avonmore protein milk reached €2.59 per litre, marking a 62.5% increase over regular whole milk, though it priced out at nearly the exact same cost per gram of protein at 5 cents.
Smaller daily items also carry inflated prices. Insomnia sells a protein latte for €4.80, representing a 14% markup over a standard €4.20 latte. In Lidl, high-protein vanilla yogurt from Irish Yogurts of Clonakilty costs €2.29 for 350 grams, while a full kilogram of Lidl own-brand natural yogurt costs just 85 cents. However, for most items in the surveyed basket, shoppers paid a lower price per gram of protein in the specialized versions, provided that specific nutrient was their primary goal.
Influencer Marketing and the Health Halo Effect
Food brands are successfully expanding their target markets by attaching black “protein” packaging to standard items like Babybel cheese, appealing to fitness-focused younger consumers and gym-goers. This retail pivot has been encouraged for years by state food board Bord Bia, which has urged food businesses to partner with influencers since 2018. Nutrition figures such as Jessie Inchasupé, known online as the Glucose Goddess, frequently link protein consumption to satiety and blood sugar regulation, often directing followers toward proprietary protein powders.
Sandra Wilkinson, communications manager and dietitian at the Irish Nutrition and Dietetics Institute (INDI), explained that consumer perception equates the protein label with healthfulness. However, she cautioned that a protein tag does not negate other ingredients. Nature Valley peanut and chocolate protein granola bars, for example, carry a 50% price markup relative to standard oats and dark chocolate bars while still containing high levels of sugar.
Actual Nutritional Needs Versus Public Perception
According to Wilkinson, population food consumption data shows that the average adult in Ireland already exceeds their protein requirements. Healthy adults require 0.83 grams of protein per kilogram of body weight under Irish guidelines, while actual intake typically ranges from 1 to 1.2 grams. “The majority of the time, people can meet their protein requirements easily through food,” Wilkinson said, noting that food companies benefit when consumers view protein as an isolated nutrient rather than part of normal meals.
While younger demographics drive the trend for fortified products, Wilkinson pointed out that older adults aged 65 and over stand to benefit most from extra protein relative to their body weight, particularly those experiencing reduced appetites. Public health data indicates that nine in 10 Irish people fail to consume enough fibre, representing a far more pressing dietary concern than protein intake.
Whey protein demand drives Glanbia market growth
Whey protein—used in clear protein drinks and specialty additives—is a natural by-product of cheese production. Nutrition multinational Glanbia noted in its annual results that it operates in a rapidly expanding market driven by unprecedented demand for the nutrient.
Do adults need protein-fortified foods and are they more expensive?
Do I need to buy high-protein supermarket products?
No. According to Sandra Wilkinson of the Irish Nutrition and Dietetics Institute, average adults in Ireland already exceed their daily protein requirements through normal food consumption.
Are protein-fortified foods more expensive?
Yes. A market basket comparison found an average 31% price markup per 100g or 100ml on protein-labeled versions of common groceries compared to their standard equivalents.
Who benefits most from added protein?
Research indicates that older adults over the age of 65 may benefit from increased protein relative to their body weight, especially if they experience lower appetites.
