b vitamins









































b vitamins are a class of water-soluble vitamins that play important roles in cell metabolism. though these vitamins share similar names, they are chemically distinct compounds that often coexist in the same foods. in general, dietary supplements containing all eight are referred to as a vitamin b complex. individual b vitamin supplements are referred to by the specific number or name of each vitamin: b = thiamine, b = riboflavin, b = niacin, etc. some are better known by name than number: niacin, pantothenic acid, biotin and folate.

b vitamins are found in highest abundance in meat. they are also found in small quantities in whole unprocessed carbohydrate based foods. processed carbohydrates such as sugar and white flour tend to have lower b vitamin than their unprocessed counterparts. for this reason, it is required by law in many countries (including the united states) that the b vitamins thiamine, riboflavin, niacin, and folic acid be added back to white flour after processing. this is sometimes called "enriched flour" on food labels. b vitamins are particularly concentrated in meat such as turkey, tuna and liver. good sources for b vitamins include legumes (pulses or beans), whole grains, potatoes, bananas, chili peppers, tempeh, nutritional yeast, brewer's yeast, and molasses. although the yeast used to make beer results in beers being a source of b vitamins, their bioavailability ranges from poor to negative as drinking ethanol inhibits absorption of thiamine (b), riboflavin (b), niacin (b), biotin (b), and folic acid (b). in addition, each of the preceding studies further emphasizes that elevated consumption of beer and other alcoholic beverages results in a net deficit of those b vitamins and the health risks associated with such deficiencies.
