Important Note

Many dietary supplements promoted for hair, skin, and nail benefits contain Biotin (Vitamin B7) levels up to 650 times the recommended daily intake.  High levels of Biotin can cause clinically significant incorrect lab test results, resulting in falsely high or falsely low results, depending on the test. Patients taking high doses of Biotin should be instructed to discontinue Biotin for at least 12 hours prior to lab testing.
