Homocysteine Homocysteine is another way to assess Vitamin B12 levels, it is not as specific as MMA because high homocysteine levels can also indicate a deficiency in B2, B6, folate, and B12
Usage: Vitamin B12 Injection (cyanocobalamin) is a prescription medication used to treat and prevent vitamin B12 deficiency
Rather than diet or oral supplements , an overdose of B12 is majorly caused due to high doses of injection, said (Ms) Roshan Kore, senior dietitian and nutritionist, SRCC Childrens Hospital, managed by Narayana Health (Haji Ali, Mumbai)
For research use only not for human or veterinary use
However, it isnt possible to know exactly how much B12 you are receiving this way
It's always advisable to consult with a healthcare professional before assuming B12 deficiency as the sole cause of fatigue, as they can guide appropriate testing and intervention
