WHITE PLAINS, NY — MARCH 30, 2005 — ConsumerLab.com reported test results today for B vitamin supplements that it recently purchased in the U.S. and Canada. Most of the products were found to contain their claimed amounts of vitamins and all tablets and caplets were able to properly break apart for absorption. However, three products failed testing. Use of B vitamins has grown in recently years due to reported benefits in treating or preventing conditions ranging from heart disease to birth defects. Sales of B vitamins eclipsed those of vitamin C in 2001 and totaled $817 million in 2003 according to Nutrition Business Journal.
The products tested included B vitamin complexes as well as single B vitamins — B-1 (thiamin), B-2 (riboflavin), niacin (B-3), B-6, B-12, folic acid and biotin. Three products failed to pass ConsumerLab.com's testing for the following reasons:
B vitamins are generally safe, although high doses of some can cause side effects. Niacin in high doses, for example, can improve cholesterol levels but may cause skin flushing and tingling and even liver injury and should be used under medical supervision. Products with doses that exceeded tolerable levels are noted in the report.
The new report is found at www.consumerlab.com/results/vitaminb.asp. Test results are shown for forty-one products. ConsumerLab.com selected sixteen of the products. Twenty-five others are included for having passed the same testing through ConsumerLab.com's Voluntary Certification Program.
Reviews of other popular types of supplements are also available at www.consumerlab.com. Reviews soon to be released include omega- 3 & 6 fatty acids (ALA and GLA from black current, borage, evening primrose, and flaxseed oils), supplements used for menopause (including isoflavones, progesterone cream, and black cohosh), nutrition powders and drinks, chromium, weight loss supplements (including CLA and bitter orange), and magnesium.
