A better measure for B12.
A new method has been developed to measure cobalamins. It uses one of two separation techniques--capillary electrophoresis and micro-high-performance liquid chromatography--combined with a detection technique called inductively coupled plasma mass spectrometry. This hybrid method allows scientists to quickly detect and measure levels of specific individual cobalamins in food and supplement samples.
