Yeast

[Alfabeta]

I read the following on the livescience website in relation to b12

‘Nutritional yeast is the best vegetarian source of vitamin B12, ... Just 2 teaspoons (6 grams) a day of nutritional yeast should cover an adult's vitamin B12 needs. ‘

Is this true?

if it is fortified with B12 which it often is.

would be helpful to have link to the article if people want to look at and check on the references

No it isn't true.

Vitamin B12 tablets are the best vegetarian source of B12. Just one tablet every 3 days should cover an adult's Vitamin B12 needs.

The tablets are cheaper than yeast, they don't go off as quickly and they don't taste as horrible. They also contain the exact same B12, grown in the exact same vats, by the exact same bacteria as the B12 that is added to yeast to make it 'nutritional'.

Marmite - you either love it or hate it. It does have small amounts gluten depending on thr source of the yeast so be careful if your gut has gluten intolerance issues like mine does.

0.5 mcg per serving. So 5 lots of marmite will give you all the B12 you need for one day.

I like Marmite, but not that much. I'd still stick to the pills.

No, Nutritional yeast (Saccharomyces Cerevisiae) doesn't produce Vitamin B12 the only life forms that do are prokaryote (bacteria and archaea) - not eukaryotes (fungi, plants or animals - including humans) they (even plants like seaweed) instead use prokaryotes to do it for them although particularly in plants this could be pseudovitamin B12 which humans

can't convert to an active form.

The only way commercially produced Saccharomyces Cerevisiae (Nutritional yeast) contains Vitamin B12 is if it artificially added - technically in the wild Saccharomyces Cerevisiae can grow with Vitamin B12 producing bacteria.
