No! Doping substances are not permitted in food, for a variety of reasons, chiefly because they have pharmacological action, and are not safe when used in food. Therefore, food products with added doping substances are not legally on the EU or UK market.
This depends on classification. Food supplements and some foods with vitamins and minerals may need to be notified. An assessment is required. Lack of notification, when mandatory, may result in fines, product seizures, and recalls. Furthermore, it is often in demand by online marketplaces such as Amazon. Member States, particularly France, have diverging criteria on classification, which may create significant issues.
Only health claims authorised under Regulation (EC) No 1924/2006 can be used. For example, creatine has an authorised claim on improvement in muscle strength, in combination with resistance training. However, compliance and appealing advertising is not the result of “copy and paste” of regulations, but precise and original application of existing rules and case-law.
There are good grounds to conclude that it is merely a statement, which must comply with the principles of fair food information, but not with Regulation (EC) No 1924/2006. It should be noted that some Member States take a more restrictive approach, though this limits the ability of consumers to use products in an appropriate manner.
The European Court of Justice has decided that CBD is not a psychoactive ingredient in the current state of scientific knowledge and thus not in the scope of the Single Convention on Narcotic Drugs. This has opened the way for the authorisation of CBD for use in foods, including sports nutrition products. However, no authorisation has been granted so far. In the UK, on the contrary, CBD is permitted, under transitional measures.
