'Riboflavin 5′- phosphate monosodium salt' or ' Vitamin B2' produced after phosphorylation of riboflavin 98 % (3a 826)

What it is. Synthetic vitamin additive consisting of the monosodium salt of riboflavin 5′-phosphate ester, obtained by phosphorylation of riboflavin (98 %) produced by fermentation from Bacillus subtilis. It is a solid product, with a minimum purity criterion of 65 %.

What it is for. This additive supplies vitamin B2 (riboflavin), used as a cofactor in energy metabolism and growth. It is authorised for all animal species and can be incorporated into compound feed, premixtures, or administered via drinking water. It would generally be used to cover riboflavin requirements when natural dietary supply is considered insufficient.

Points to watch. The instructions for use must specify storage conditions and stability to heat treatment. Due to risks of inhalation and skin or eye contact, organisational procedures and, where applicable, personal protective equipment (respiratory protection, safety glasses, gloves) are required when handling the additive and premixtures.
