Apart from the ridiculously incompetent proofreading that you would expect from daily exoress, glad to see b12 getting a mention.
However this extract;
"A deficiency in vitamin B12 causes the number of enzymes that help with digestion to decrease in the bloodstream.
This then increases the amount of waste in the blood(???), which has the potential to cause bad breath"
Have I missed a crucial bit of medical knowledge here or is that meant to say gut instead of blood
