[86] Fortified foods [edit] Foods for which vitamin B 12 -fortified versions are available include breakfast cereals, plant-derived milk substitutes such as soy milk and oat milk, energy bars, and nutritional yeast
The following groups of people are at a greater risk of developing a vitamin B12 deficiency: Vegans or vegetarians People 75+ years Having a digestive system disorder like Crohns or celiac disease Drinking excessive amounts of alcohol Having Sjgrens syndrome Taking certain medications like oral birth control or metformin Common symptoms of a vitamin deficiency include fatigue, numbness, poor balance, memory loss, and breathlessness
Blood glucose, insulin, lipid panels, and liver function tests would help track both efficacy and potential adverse metabolic effects
If the label says it contains B12 but the solution shows no color, either the B12 concentration is extremely low (possible but unusual), the B12 has degraded (possible if exposed to light), or there was a labeling error (possible at any pharmacy)
It is important however, to know what disease process may be contributing to a B12 deficiency and to follow the correct dosing protocol for oral or injectable B12 supplementation
