Quote from the page I referred to: "according to Acu-Cell Nutrition, when you receive an overabundance of vitamin B12, it can result in a severe calcium deficiency. According to the University of Maryland Medical Center, people whose calcium is low are at higher risk for developing hypertension. This means when vitamin B12 is taken to excess, you risk decreasing your calcium level and increasing your risk of hypertension." I really don't see how you could get the impression that you should take more B12 from that statement.
