Well, if you go in on bulk B12 with some friends at $1k/kg, I guess you could limit it to 10¢. In reality, more accessible supplements run me closer to $5/month

Well, if you go in on bulk B12 with some friends at $1k/kg, I guess you could limit it to 10¢. In reality, more accessible supplements run me closer to $5/month. I'm fine with that. Risking a deficiency isn't worth $5/month, and I don't have an efficient or viable alternative.
