While vitamin D supplements have surged in popularity, a report in the *Journal of the American Medical Association* noted a significant increase in adults taking more than 4,000 IU per day. It is crucial for women to understand the safe maximum d3 per day to avoid potential health risks associated with excessive intake.

According to the National Institutes of Health (NIH), the tolerable upper intake level for most adults is 4,000 IU of vitamin D per day, a threshold that should not be exceeded without medical supervision. This maximum IU of vitamin D per day is a critical safety guideline, as excessive intake can lead to harmful side effects.
