Yes, Vitamin B12 is water-soluble. This characteristic is essential for its role in the body, as it allows B12 to dissolve in water and be carried through the bloodstream. The solubility in water means that any excess amounts of B12 are usually excreted through the urine rather than stored, making B12 toxicity rare. However, regular intake is necessary to maintain healthy B12 levels, especially for those with dietary restrictions or absorption issues.
