<h3>What is
b-vitamin?</h3>
B vitamins are a group of water-soluble vitamins that are crucial for red blood cell production and cell metabolism. Despite having names that sound similar (B1, B2, B3, etc.), these vitamins are chemically different substances that frequently coexist in the same foods. Dietary supplements that include all eight are typically referred to as vitamin B complexes. The exact number or name of each vitamin, such as B1 for thiamine, B2 for riboflavin, and B3 for niacin, is used to identify individual B vitamin supplements. Some substances, like pantothenic acid, biotin, and folate, are better known by their names than by their chemical names.
Each B vitamin either functions as a cofactor (usually a coenzyme) for important metabolic processes or functions as a precursor required to produce one.
