While the 8mg dose is higher than the daily recommended intake for most adults, it is well within safe limits and beneficial for those with specific needs. However, if you're new to biotin or prefer a lower dose, you might want to start with a smaller amount. Also, the price is slightly premium, reflecting the brand's clinical-grade quality.

Overall, THORNE Biotin is a reliable, high-quality supplement that delivers on its promises.
