TESTING OF B-VITAMINS BY CONSUMERLAB.COM FINDS SEVERAL SHORT ON FOLIC ACID
— New Report Covers B-Complexes, Thiamin, Niacin, B-6, B-12, Biotin and Folic Acid
WHITE PLAINS, NEW YORK — SEPTEMBER 10, 2007 — Half of the B-complex supplements recently selected by ConsumerLab.com for testing were found to lack the total claimed amounts of folic acid, an essential nutrient also known as vitamin B-9. 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. According to Nutrition Business Journal, B vitamins are one of the top selling supplements in the United States, with sales of $937 million in 2005.
"It's terrible that some supplements are missing a significant amount of folic acid. People count on folic acid to prevent disease and treat deficiency," said Tod Cooperman, MD, President of ConsumerLab.com. Folic acid supplementation may decrease the risk of colon cancer and, along with vitamin B-6, reduce the risk of heart disease and stroke in adults. Deficiency can have wide-ranging effects including anemia and an increased risk of spinal cord defects in infants. It is important, for example, that women who are or may soon become pregnant get 400 mcg of folic acid each day from a supplement in addition folic acid from their diets. Folic acid is particularly susceptible to being destroyed by exposure to heat and moisture, as may occur with improper shipping or storage.
Tests results for twenty-six B vitamin supplements (including B-complexes and single B vitamins) are published in the new report found at www.consumerlab.com/results/vitaminb.asp.
