B vitamins are one of the top selling supplements in the United States, with annual sales exceeding $900 million. But half of the B-complex supplements recently selected by ConsumerLab.com for testing lacked the total claimed amount of folic acid.
An essential nutrient, folic acid may decrease the risk of colon cancer, heart disease and stroke in adults and reduce the risk of spinal cord defects in infants when taken by women during pregnancy.
Nearly half of the expected folic acid was missing in two products, one of which bore a USP verification seal indicating its ingredients had been tested and verified by that organization. A third B-complex supplement lacked more than one-quarter of the folic acid listed. A folic acid-specific supplement was also slightly low in the ingredient. Problems were not found with levels of other B vitamins in the products
