VIB7

Vitamin B7, also known as biotin, is essential for maintaining healthy hair, skin, nails, and supporting energy metabolism. While biotin deficiency is uncommon, it can lead to noticeable symptoms like hair thinning, brittle nails, or skin rashes. The Vitamin B7 test (Biotin) detects any deficiencies or imbalances that could impact your well-being.

Why the Blood Test for Vitamin B7 Matters?

Since biotin is directly linked to hair and skin health, undergoing a biotin B7 vitamin test can help clarify whether low levels are causing hair loss or poor skin condition. This test also plays a crucial role in diagnosing metabolic or nutritional issues that may stem from a vitamin B7 deficiency.

FAQs

What does the Biotin test measure?

The Biotin (Vitamin B7) test measures the amount of biotin present in your blood. Biotin is a water-soluble vitamin that plays an important role in energy production, metabolism of fats and carbohydrates, and maintaining healthy hair, skin, and nails. 

Who should consider this test?

This test may be particularly useful for people experiencing persistent hair loss, brittle nails, recurring skin rashes, or unexplained fatigue. It is also recommended for those with restrictive diets, people on long-term anticonvulsant therapy, or individuals having inflammatory bowel disease.

What are the symptoms of B7 deficiency?

Biotin deficiency is rare but can cause noticeable issues. Common symptoms include thinning or loss of hair, red and scaly skin rashes (often around the eyes, nose, and mouth), fatigue, irritability, and tingling in the hands and feet. 

Can supplements improve levels?

Yes. Biotin supplements, often found in hair and nail formulas, can restore low levels and support overall health.

Are biotin supplements safe?

For most people, biotin supplements are safe when taken at recommended doses. However, very high doses may interfere with certain blood tests, particularly those measuring thyroid, heart, or hormone function, leading to inaccurate results.
