If you are taking medications for diabetes, it is important to consult with your doctor before starting any new supplements, including biotin. Biotin is typically found in abundant amounts in food, so a deficiency is rare. It is best to focus on a healthy diet rich in fruits and vegetables to ensure you are getting all the necessary nutrients. If you suspect a biotin deficiency, speak with your healthcare provider to discuss potential testing and appropriate supplementation. It is always important to consult with a healthcare professional before making any changes to your medication or supplement routine.
