Riboflavin (Vitamin B2)
Is it halal?
That depends on the source used, which is why this page states the source rather than a verdict:
Varies by manufacturer
Can be made from either plant or animal fat, including pork, depending on the producer. The label rarely says which, so a halal mark or a written answer from the manufacturer is what settles it.
Usually produced by bacterial fermentation today, but can be derived from egg or liver. Certified products state the source.
- Found in
- Cereals, sauces, dairy, vitamin supplements
Others from the same source
This page describes what additives are made from. It does not issue rulings. Where a source varies by manufacturer, the only reliable answer for a specific product is its halal certification or the manufacturer’s own statement — and where the schools of law differ, the position of the school you follow is the one that answers your question.
