Biotin is an important part of enzymes in the body that break down substances like fats, carbohydrates, and others. There isn't a good test for detecting low biotin levels, so it's usually identified by its symptoms, which include thinning hair and red scaly rash around the eyes, nose, and mouth.
Biotin is used for biotin deficiency. It is also commonly used for hair loss, brittle nails, and other conditions, but there is no good scientific evidence to support these uses. Biotin supplements might interfere with some lab tests. Talk with your doctor if you are taking biotin supplements and need to have any blood tests.
Uses & Effectiveness ?
Likely Effective for
Possibly Ineffective for
When applied to the skin: Biotin is likely safe for most people when applied in cosmetic products that contain up to 0.6% biotin.
Special Precautions and Warnings
Children: Biotin is likely safe when taken by mouth. It's been used safely in doses of 5-25 mcg daily.
An inherited condition in which the body cannot process biotin (biotinidase deficiency): People with this condition might have low levels of biotin and may need a biotin supplement.
Kidney dialysis: People receiving kidney dialysis might have low levels of biotin and may need a biotin supplement.
Smoking: People who smoke might have low biotin levels and may need a biotin supplement.
Laboratory tests: Taking biotin supplements might interfere with the results of many different blood lab tests. Biotin can cause falsely high or falsely low test results. This might lead to missed or incorrect diagnoses. Tell your doctor if you are taking biotin supplements, especially if you are having lab tests done. You may need to stop taking biotin before your blood test. Most multivitamins contain low doses of biotin, which are unlikely to interfere with blood tests. But talk to your doctor to be sure.
