B12

B12 5000 MCG Daily

Vitamin B12 is unique because it is primarily found in animal products. Excellent dietary sources include meat, fish, poultry, eggs, and dairy. Fortified foods like certain cereals, plant-based milks, and nutritional yeasts are important for vegetarians and vegans. Deficiency can lead to serious health problems, most notably megaloblastic anemia, which causes fatigue, weakness, and shortness of breath due to impaired red blood cell production. Neurological symptoms such as numbness, tingling, difficulty walking, memory problems, and even psychiatric issues can also arise, as B12 is crucial for nerve health. Certain conditions, like pernicious anemia, Crohns disease, and some medications (e.g., metformin), can impair B12 absorption, making supplementation necessary. Regular intake or supplementation is essential for overall health and well-being.
