Nucleotides are made from yeast cells including torula yeast and brewer yeast. One of the larger manufacturer of nucleotides is using a specific strain of torula yeast and growing on alcoholic beverages such as beer and wine to manufacture the Nucleotide. But the residual of amount of alcohol in nucleotide is very minimum such as 200 part per millions (PPM).
Nucleotides are now adding to infant formulas such as in Similac and Enfamil brands. Islamic dietary laws considered alcoholic beverages are Haram. Nucleotide is considered as Mushbooh ingredient by MCG.
