The B12 that I use in my practice is methylcobalamin - one of the coenzyme forms of vitamin B12 that is easy for the body to use
Common signs of B12 deficiency include fatigue, weakness, pale skin, shortness of breath, numbness or tingling in the hands and feet, difficulty maintaining balance, and cognitive issues like memory problems
Decrease dose if: Experiencing consistent side effects (headaches, fatigue, GI disturbance), achieving satisfactory results at current dose with no need for escalation, or cost considerations favor using minimum effective dose
People who dont eat animal products, like vegetarians and vegans, might struggle to get enough B12 through diet alone, although you can find B12 in fortified cereals and soy products
A deficiency of vitamin B12 can also cause shortness of breath or heart palpitations, as well as gastrointestinal symptoms including constipation, diarrhea, appetite loss, or gas
