You take the label too literally
The daily value (DV) information on supplement labels was updated in July 2016, but panels won’t be fully updated until July 2019. This may result in getting too much or too little of a given nutrient if you rely on the label. “If you are taking folic acid, you may be getting as much as 70 percent more of this B vitamin than you need based on the older DV information,” says Tod Cooperman, MD, president of ConsumerLab in White Plains, New York.
There is an upper limit for folate from folic acid and we know that very high levels can cause kidney damage or mask vitamin B12 deficiency. Relying on the DV for vitamin D could put you at risk for a shortfall of this important vitamin.
