In the EU, the categorization of a substance is made based on its effects on the body. If the substance contributes only to the maintenance of healthy tissues and organs, ie helps the body maintain a healthy level of inflammation, then it may be considered to be a food ingredient. If it can be shown to have modifying effects on the body's natural physiological functions and is sold as treating a medical condition, then it will be considered a medicinal product. Nutraceuticals have elements of both foods and medicinal products, but do not completely satisfy the requirements of either regime. Due to the peculiarity of their design they are presently unregulated. This would allow RCP to market Abloc in the EU.
