Biotin
Biotin is a cofactor for carboxylase enzymes central to fatty acid synthesis, gluconeogenesis, and amino acid metabolism, and supports keratin infrastructure.
Medically reviewed by Dr. Jonathan Snipes, MD. Last reviewed May 6, 2026.
What It Is
An injectable form of biotin (vitamin B7) at 10mg/mL. Self-administered intramuscular or subcutaneous. Often used for hair, skin, and nail support.
How It Works
Biotin serves as a coenzyme for carboxylase enzymes in energy and lipid metabolism and supports the keratin structure of hair and nails. Injectable delivery ensures full dose availability independent of gut absorption.
Who It's For
Patients seeking hair, skin, and nail support or correcting biotin insufficiency. Popular as an adjunct to broader wellness protocols.
Who Should Avoid It
Biotin can interfere with laboratory immunoassays (thyroid panels, troponin, hormone tests). Flag for provider review if bloodwork is pending. Otherwise very well tolerated.
