Vitamin B12 deficiency with Dr Brian Clement
Studies show that those following a typical animal-based diet require more vitamin B12 than those who do not. This is because the typical diet leads to digestive atrophy. Because B12 is peptide-bound in animal products and must be enzymatically cleaved from the peptide bonds to be absorbed, raw food vegans who have a more powerful digestion actually get more B12 by reabsorption from the bile than they do from external food.
