Biotin is important for the functioning of your nerves, normal metabolism, and many other body processes. The National Academy of Sciences has determined that an adequate daily intake of biotin for adults is 30 micrograms (mcg). Most people can meet their daily biotin needs by consuming foods that contain biotin. Among others, these foods include nuts and nut butters, soybeans and other legumes, whole grains, bananas, and cooked eggs. However, some conditions (such as Crohn's disease) and medications (such as antibiotics or anticonvulsant drugs) may raise your risk for biotin deficiency, increasing the likelihood that you would need a biotin supplement such as Meribin.
Talk to your doctor about whether you need to take Meribin or any other dietary supplement.
