As of November 2026, B12 has been mentioned in one podcast episode on PowerfulJRE (Jun 2024). Discussed as an essential vitamin, with warnings about the cyano form of B12.

Vitamin B12, also known as cobalamin or extrinsic factor, is a water-soluble vitamin involved in metabolism. One of eight B vitamins, it serves as a vital cofactor in DNA synthesis and both fatty acid and amino acid metabolism. It plays an essential role in the nervous system by supporting myelin synthesis and is critical for the maturation of red blood cells in the bone marrow. While animals require B12, plants do not, relying instead on alternative enzymatic pathways.
