"Vitamin B12 is actually a red porphyrin pigment. It is an essential building block of red blood cells. Porphyrins are miniature, crystal-like molecules. Vitamin B12 contains a cobalt ion at the centre of its porphyrin ring; hence the reference to cobalamin. Between this Organic Liquid B12 and the Synergy B12 we can barely keep these products in stock — the efficacy is unmatched by all other products in the market. And both are products produced by family-run businesses." ~ David Wolfe
