As natural supplements and herbal actives grow ever more popular, we provide support in authenticating your ingredients and products, supporting your claims substantiation, and testing your products’ stability.

We have developed many robust and reliable analytical methods for a range of natural and herbal products and raw ingredients, with many of our tests analysing for a specific chemical unique to the original source. We aim to work with you to find a tailored approach supporting your particular product development needs.
