This is due to the fact that around 350 of the plants in question have not had their conservation status assessed, which means there is a danger that many of them could be at risk of extinction.
On improving global health Dr Samuel Pironon from Kew and co-author of the study emphasised: “More than two billion people suffer from malnutrition worldwide so improving long-term access to a diversity of wild and cultivated plant sources…is key to human subsistence”.
Meanwhile, before those plants are made available on the shelves of the UK, there are a number of other sources of vitamin B already in existence.
Sources of vitamin B12 include meat, fish, milk, cheese, eggs, and some fortified breakfast cereals according to the NHS.
