Does Your Multivitamin Have Too Much Folic Acid?
Folic acid is in multivitamins because it is provides the essential B vitamin, folate. Getting too much folate, however, carries risks. What most people don't know is that you actually get 70% more folate from folic acid than labels currently reveal and many supplements expose you to amounts of folate which are not only way above what you need but over the daily limit for tolerable intake. Companies now have until mid-2018 or later correct their labels, but until then you may be in the dark.
To find out which multivitamins exceed the tolerable limit for folate, see the update in the Multivitamins Review. You'll also learn how the daily requirements for many other nutrients have changed and differ from what labels currently tell you.
