While it is a beloved staple in Britain, Marmite's high vitamin content has caused a few headaches abroad. In 2011, Denmark made headlines when it enforced a ban on foods with added vitamins, which included our favourite yeast extract. The ban was due to laws restricting the sale of fortified foods without specific approval, leading to a temporary disappearance from Danish shelves until it was reportedly lifted in 2014.

Canada has also had a complicated relationship with the spread, with reports of it being banned or seized over the years due to certain additives being deemed illegal under their food regulations. These incidents serve as a stark reminder that one country's treasure can be another's contraband.
