Protein Works Research

We don't just make multi-award-winning nutrition products - we study how people use them in their daily lives. This helps us understand exactly what our consumers want and need from their functional nutrition. 

Here in the Protein Works Research Hub, we publish original consumer studies drawn from thousands of real customers, covering usage habits, reported outcomes, motivations, and trends across the health & nutrition category. 

Data from real people who actually take our products. 
 

What We Research 

Real people. Real data. Every study published here is based on original consumer survey data collected directly from verified Protein Works customers. We publish the full methodology, sample sizes, and demographic breakdowns - so you can assess the findings for yourself. 

Our research covers: 

  • Who is using functional nutrition products and why 
  • How usage habits and motivations are shifting over time
  • What outcomes consumers actually report - and where expectations aren't being met
  • Emerging trends in areas like protein intake in older adults, the emerging use of creatine, and meal replacement behaviour

Meal Replacement Consumer Research 2026

474 respondents · UK adults · Published 2026 

71.7% of meal replacement users surveyed are women over 45 - and 95.5% say the product is well-suited to providing nutritional support to GLP-1 programmes. 

Interestingly, even in a category built around weight management, the majority say they want to feel better, not look better. 

The findings reframe what's actually driving the diet shake category.

Whey Protein Consumer Research 2026

444 respondents · UK adults · Published 2026

Over half of whey protein users surveyed are aged 45 or over, and breakfast - not post-workout - is when the majority of users are enjoying their shake. 

What's more, consuming whey protein shakes to provide nutritional support during GLP-1 medications is also emerging as a use-case for many, rising to nearly 8% among 45–54 year olds. The data points to a category moving from the historical link to exercise and performance to instead supporting every day lifestyles.

Creatine Consumer Research 2026

542 respondents · UK adults · Published 2026

Almost half of creatine users surveyed were aged 45 or over - and nearly 30% of those were female. 

While 91.3% of users agreed that Creatine 360 - BLACK helped them train harder or perform better, more of the cohort said that their primary motivation was to feel better, not look better.

The data challenges almost everything the industry assumes about who takes creatine and why.

Our Methodology 

We take research integrity seriously. Every Protein Works Research study follows a consistent methodology: 

  • Verified respondents - all participants are confirmed Protein Works customers who have purchased and used the relevant product 
  • Transparent sample sizes - we publish full respondent counts and do not extrapolate from small samples
  • Full demographic disclosure -  age & gender are reported for every study 
  • No selective reporting - findings that challenge assumptions or show mixed results are included, not removed 
     

We believe credible research means showing the full picture.
