Claims substantiation

At GCRS in Cardiff, our claims substantiation service includes ensuring compliant labelling on products, covering claims such as: Vegan, natural, organic, paraben-free, non-GMO, cruelty-free, and non-toxic.

When you make claims about the nature of a product or potential benefits, it's essential to be able to prove it.


Claims can be substantiated through a range of methods including clinical testing, consumer trials, sensory evaluations or dermatological testing; in short, the method needs to be backed by data and supported by verifiable evidence. The team at GCRS will help you ensure that the claims testing and substantiation is done using scientifically valid methodology that can be reproduced, if required, using an appropriate range of subjects and uses tests that meet the criteria as set by the regulatory authority relevant to your product.


As well as being a legal requirement for many claims, it is an important part of branding for businesses; such statements can help you stand out in a competitive market, or offer something genuinely verified in a market where it can be harder to find a safe product. Being able to create trust is an important thing for any business.


Our support includes: 

  • Drawing up the study protocol to substantiate testing through clinical testing, sensory evaluation, and dermatological testing.
  • Having an experienced team to conduct the tests and studies. 
  • Help presenting claim substantiation information in a technical document according to the market guideline.
