بيوتين

Three weeks in and my nails stopped peeling at the edges, which never happened with cheaper supplements. The high-potency dose is clearly doing something for my hairline too, and one capsule a day is all it takes.

The capsules are easy to swallow and I've noticed my nails feel a bit stronger after three weeks of taking one daily. I just wish the bottle came with a few more tablets since I'm already thinking about reordering.
