The NIH notes that vitamin B12 deficiency can cause fatigue, anemia, and neurological changes such as numbness or tingling, which is why visit context matters more than simply ordering a wellness shot online
Individuals with Digestive Disorders Conditions like Crohns disease, celiac disease, or gastric bypass surgery can impair B12 absorption
In UK primary care, patients with a B12 above 1,000 pmol/L had a one-year cancer incidence rate ratio of 4.72 compared with those in the reference range
To evaluate growth on solid media, in all cases -with the exception of the metE mutant, which only grew in the presence of B12 and, therefore, plating with and without B12 was performed from liquid cultures supplemented with B12- the liquid cultures grown without B12 were plated in solid 7H10-ADC plates supplemented with or without AdoCbl (10 g/mL) and/or L-Met (25 g/mL)
