In 2017, the FDA issued a safety warning alerting healthcare providers and the public that supplemental biotin can interfere with certain lab tests, leading to falsely high or low results for various analytes. A common question that has arisen from this is, "Does biotin affect vitamin D?"—particularly concerning routine blood work.

According to the FDA, high-dose biotin supplements may significantly interfere with specific lab tests, including those for vitamin D, potentially causing incorrect results. This interference can lead to false readings, not an actual increase in the body's vitamin D levels.

The Food and Drug Administration (FDA) issued a safety warning in 2017 about the potential for biotin to interfere with certain lab tests. This interference can impact immunoassays used to measure vitamin D, raising the critical question: can biotin affect vitamin D?

According to a Mayo Clinic study, over 7% of emergency department patients had biotin levels high enough to cause false lab results on commonly used assays. This critical risk highlights the importance of understanding **what does biotin interfere with**, especially regarding crucial blood tests for conditions like heart attacks and thyroid disorders.
