Functional foods must be safe and efficient. There should be scientific evidence to prove both their biological activity and their safety.

This must be guaranteed if customers are to feel safe and confident with the products. We have a wide range of methodologies that comply with Spanish and European safety standards (Agencia Española de Seguridad Alimentaria-AESAN and European Food Safety Authority-EFSA) and guarantee that foods are safe for human consumption. We perform the following studies:

• Chronic, sub-chronic and acute toxicity studies in several animal species.
• In-vivo and in-vitro mutagenicity studies (Ames test, micro-nucleus, chromosomal, erc.).
• Studies on interactions between ingredients.

CTNS also carries out a variety of microbiological analyses and impurity controls of minority components or contaminants o ensure the biological and chemical safety of food.
