Recent laboratory tests of 27 types of multivitamins has again demonstrated the worrisome fact that many packages of dietary supplements on store shelves don’t contain what their labels say.
The tests, conducted by a specialist research and publishing firm that performs independent testing of supplements for the industry and consumers, assigned nine of the 27 products a failing grade. This means they failed either to contain the labeled ingredients in the amounts described, or failed related tests of disintegration and impurity levels.
One product aimed at pregnant women contained only 75 percent of the listed amount of folic acid – a troublesome finding since insufficient levels of folic acid have been found to be closely associated with serious birth defects.
