Nothing over oral: unless you have some type of severe B12 deficiency or pernicious anemia.

B12 injections : There are no benefits to getting B12 injections unless you have a deficiency and you are not able to absorb it thru the gut . Some times Vegans can become deficient because they do not eat animal fat and they would have to get injections . I have heard of psychiatrists giving B12 injections during periods of increased stress ; not sure why !! Perhaps to calm the nerves . Hope this helps

I would add that there is a "range" of normal levels of B12 and one person may have more energy, feel better emotionally, and lose weight more easily at a higher level than another. B vitamins are critical for energy , fat burning, and mood stabilizing reactions. Finally, some people have a genetic "typo" and require their B vitamins, to be activated and should request "methylated" B vitamins.

Please advise if it's bad to take both b-12 and b-complex?

OK to take both: B12 is relatively more expensive than the other Bs. Consequently, most manufacturers put about 100 mcg in their multis. OK to take additional B12.

Usually not : Your body will eliminate excess vitamins in your urine. Never take more than 1 b complex tablet/day.
