Though there have been no side effects documented from vitamin B12 use from either supplementation or food consumption, you should always check with your doctor prior to beginning supplementation of any type
Regardless of which method used, a healthcare professional will typically inject the vitamin using a sterile needle and precise dosing instructions
If we are treating autoimmunity or pernicious anemia, you will receive B12 weekly or twice weekly for 6-12 weeks
The B12, whether methylcobalamin or cyanocobalamin, goes into the muscle and into your system without depending on a digestive step that may not be working well for you
The needle should be inserted at a 90-degree angle for most patients, though very thin individuals may need to use a 45-degree angle or pinch the skin to ensure subcutaneous rather than intramuscular injection
I got my first loading dose on Monday and boy did it hurt going in
