Acharya Prashant addresses the concern that a vegetarian diet might be insufficient for essential nutrients like Vitamin B12, particularly for young people. He argues that modern life is already heavily dependent on factory-made products, such as vaccines and medications, which are not found in nature. He points out the inconsistency in accepting factory-made vaccines for diseases like COVID-19 or smallpox while insisting that nutrients like B12 must come from 'natural' animal sources. He suggests that if a nutrient is lacking, one should simply take a factory-produced supplement rather than resorting to the slaughter of animals.
