It can be easy to ingest more than 10,000 IU of vitamin A (more than three times the amount recommended for men and four times the amount recommended for women) if you eat a lot of fortified cereal and liver in addition to taking a multivitamin containing retinol or retinyl compounds every day.

Plenty of evidence from earlier research shows too much vitamin A can harm bones. Excess vitamin A can have other effects as well. Birth defects occur more often in fetuses when pregnant women take more than 10,000 IU of supplemental vitamin A. To protect yourself, get most or all of your supplemental vitamin A in the form of beta carotene, and try to adhere to the Recommended Dietary Allowance (RDA) for vitamin A.
