June 1, 2015 • There is mounting evidence that small amounts of essential nutrients like choline and folate have a big impact on human health. However, nutritional studies that attempt to quantify the effects of essential nutrients often produce unclear or contradictory results.
There are several reasons for this, but chief among them is the assumption that all of us process food exactly the same way. This is simply not the case. No one is metabolically identical or even similar to anyone else – not even identical twins. We all require different amounts of specific nutrients and vitamins. Scientists at the UNC Nutrition Research Institute believe this common misconception is responsible for so many contradictory study results.

And, yet, nearly half of the U.S. population takes multivitamin supplements—even in times of financial downturn. In 2010 the U.S. supplements industry reached $28 billion in annual sales. And, although no clear scientific need has been defined for vitamin supplementation, the most common reason for taking vitamins is a desire to “improve” or “maintain” overall health, according to a poll conducted by the National Institutes of Health in 2013.
