Acharya Prashant addresses the common argument that meat consumption is necessary to obtain Vitamin B12. He questions why someone would go to a shop to buy meat specifically for B12 when they could simply purchase a B12 supplement from the same market. He points out that plant-based, vegan B12 supplements are readily available, organic, and significantly cheaper than meat. He explains that B12 is not produced by animals themselves but originates in the soil. Animals ingest it when they consume grass and plants that have soil attached to their roots. Historically, humans obtained B12 naturally by eating fruits and vegetables directly from the earth, but modern hygiene practices involving rigorous washing have removed these soil particles, leading to a deficiency. He concludes that since most people already take various supplements like Vitamin D or Calcium, it is more logical and ethical to take a B12 supplement rather than using it as a justification for eating meat.
