Researchers have evaluated recent developments in nutrition science, analytical technology and the continuing evolution of statutory regulations and conclude that most current international reference methods are no longer fit-for-purpose to accurately determine vitamin content in foods and food supplements.
They recommend that new and/or updated reference methods and regulatory standards should be considered for the analysis of vitamins A, D, E, K, B1, B2, B3, B5, B6, B7, B9, B12, C and carotenoids in foods and food supplements.
They also state that this area of nutrients may benefit from globally harmonised definitions specifying what compounds to include or exclude for analysis, and applicable bioactivity factors.
