Speaker 2
Thank you very much, Sir Edward.  It's a pleasure to serve under your chairmanship this afternoon, and I beg to move that the Committee has considered the draft Food Supplements Purity Criteria (Magnesium L-threonate monohydrate) (England) Regulations 2026.  Magnesium L-threonate monohydrate, just to say it again, has recently been authorised as a novel food following a public consultation and safety assessment by the Food Standards Agency, which concluded that it is safe under the proposed conditions of use. 

The instrument sets the purity criteria, that is the required safety and quality standards for this form of the mineral magnesium, to permit its use and sale in food supplements in England.  Honourable members, this statutory instrument is a routine and technical measure which ensures food supplement regulations continue to operate effectively following the authorisation of novel substances for use in food supplements.  The regulatory approach taken here is well established: when new substances are authorised, it is necessary to update the relevant legislation so that they can be used in practice and to ensure that clear and enforceable quality standards are in place.  Honourable members will be aware that under our existing legal framework, vitamins and minerals may only be used in food supplements if they are both listed in legislation and meet appropriate safety and quality standards. 

Magnesium itself is already a permitted mineral listed in legislation.
