I was just perscribe methylb12 injections by my doctor for low energy, etc. Is there any side effects of taking too much. I will be taking an amount way over the recommened daily amout. I will be taking on average 1.25 mg every day in an injectable form. Is this too much because the recommened intake is only 6mcg per day! I know one can take alot of b12 but is 1.25mg in injectable form too much?THakn
