Some Marmite is kosher, but not the jar you usually buy. Only two formats are certified by the Kosher London Beth Din (KLBD): the 8g individual portions and the 600g catering tubs, and only when they carry the KLBD logo. The standard supermarket jar is not kosher-certified. So with Marmite, checking the mark on the specific pack is the whole game.
This is information, not a ruling. Follow your own kashrut authority.
What is actually certified
As things stand, the KLBD certifies two Marmite formats as Parev (containing neither meat nor dairy, so it may be eaten with either):
- The 8g portions, when they bear the KLBD logo on the outer case, or carry an expiry date after 19 March 2024 on the individual portions.
- The 600g catering tubs, which bear the KLBD logo.
Those are the kosher ones. The KLBD’s own position on everything else is blunt: other sizes are not kosher.
What is not certified
The everyday Marmite jar, the one most people have in the cupboard, is not KLBD-certified, and neither are the Squeezy bottle or the various limited editions. They are made to the same vegan and vegetarian recipe, but kosher certification is a specific supervised status, not the same thing as “no meat in it”, and it has been granted only to those two formats.
This catches people out, because the certified and uncertified packs can look almost identical. Old stock in the same tub, without the KLBD stamp, is not kosher. The mark is the thing to look for, not the brand or the size alone.
It has been on and off over the years
Marmite’s kosher status has not been a constant. The certification has lapsed and been reinstated more than once, to the point where “Marmite is kosher again” has been a genuine headline in the Jewish press. This is another reason not to rely on memory or on what a jar’s status was a few years ago. Check the current pack.
Where to find the certified versions
The certified formats turn up through kosher shops and wholesalers rather than always sitting on a standard supermarket shelf. The 600g tubs are sold by the likes of Costco, and the 8g portions through online grocers. Wherever you buy, the rule is the same: look for the KLBD logo on that specific pack.

Quick answers

What does the KLBD certify Marmite as? Parev, meaning it contains neither meat nor dairy and can be eaten with either.
How do I know if my Marmite is kosher? Look for the KLBD logo on the pack. Without the mark, treat it as not certified, even if the tub looks the same.
