That’s the question NPR’s Dan Charles asked recently:
Why Did Vitamins Disappear From Non-GMO Breakfast Cereal?, NPR, 5 December 2014
You can probably guess what they discovered:
Post Foods, the maker of Grape-Nuts, informed us in a prepared statement that vitamins were removed because “they did not meet non-GMO standards.”
Cereal and vitamin manufacturers weren’t forthcoming with exactly why vitamins didn’t meet non-GMO standards. But Charles and his crew discovered that:
- Some companies are most likely making vitamin B-12 and riboflavin using genetically modified microbes.
- Vitamin-makers have to show that their microbes consumed feed — glucose, for instance — that came from non-GMO sources.
- Some vitamins have to be mixed with other substances, such as cornstarch. [Most corn in this country is GMO.]
It seems pretty safe to conclude that most vitamins and dietary supplements sold in the US have been produced using genetic engineering, unless their labels indicate otherwise. Even then, a product may contain about 1% GMO and still meet the non-GMO definition.
