Many people experience B12 deficiencies that can lead to fatigue, cognitive issues, and weakened immune function

Therefore, you must obtain it from animal products (meat, fish, dairy, eggs) or supplements
At the maintenance dose of 2.4mg per week, that same 10mg vial lasts just over four weeks

This makes the fatigue and weakness even worse
