Most people get enough vitamin B-12 in their diet, but a deficiency may occur in certain health conditions (e.g., poor nutrition, stomach/intestinal problems, infection, cancer)

For long-term storage, -20 C freezer storage is the conservative research default unless the supplier gives a different compound-specific instruction
Balanced diet: Incorporating leafy greens, nuts, and seeds can complement B12's benefits
