Protects brain function
Biotin helps keep our brain function healthy. We need vitamin B7 to produce myelin, which is a substance that protects our nerve cells and helps them communicate with each other. Myelin is essential for a healthy brain, and without it, we would not be able to think or remember properly. Biotin deficiencies have been linked to cognitive problems and dementia.
Most people get enough biotin from their diet or from supplements and do not need to take extra biotin for brain health. However, some people may benefit from taking extra biotin if they have a deficiency or are at risk for cognitive problems.
