Are energy drinks halal? Taurine, caffeine and what a certificate covers

Updated 9 November 2026

Energy drinks come with a bull on the can in some cases and a rumour about taurine in most, and people ask whether the drink is halal at all. This page separates the rumours from what can be checked, and says where we found no ruling.

What is taurine, and where does it come from?

Taurine is an amino acid-like compound found naturally in animal tissue, which is the origin of the old rumour that it comes from bulls. In energy drinks it is made industrially. Red Bull states in its own FAQ that its taurine is synthetic and not made from bulls. We checked only that brand, so for another can, look at the maker's statement or the certificate.

Is there a ruling on energy drinks?

LPPOM MUI, the certification body of Indonesia's Ulema Council, published guidance on energy drinks in 2019. It says the origin of the taurine, any gelatin coating on added vitamins and the flavourings must be known, and it advises choosing a certified drink. We found no formal ruling declaring the category halal or haram from JAKIM, MUI, HMC or HFA. Certification attaches to a named product in a named market. A product can be certified in Indonesia and not in the UK, and the same brand can carry different recipes in different countries. Scholarly answers exist on individual brands: an AskImam answer addresses Red Bull and V, and you should read the reasoning for yourself. If you follow a certifier, look for its mark on the can.

What should I look for on the label?

• A halal mark from a certifier you trust, on this product.
• Colours. Carmine (E120) is an insect-derived red; see the carmine page.
• Flavourings. Alcohol is sometimes used as a carrier, as set out in alcohol in food flavouring.
• Gelatin. LPPOM MUI's guidance lists gelatin coatings on added vitamins as something to verify. We found no evidence that any particular brand uses one.

What about caffeine?

Caffeine does not make a drink haram, and we found no ruling that says otherwise. Whether to drink it is a health decision. A 250 ml can of Red Bull contains about 80 mg of caffeine, according to its product page, and the NHS advises no more than 200 mg of caffeine a day in pregnancy.
