Nail growth help?

Hey ladies! I have such terrible thin/bendy/peeling nails. I’m looking for something I can maybe take like a pill or put on my nails like a polish that will help me grow stronger/tougher nails that maybe I could eventually grow out and shape myself to paint and actually look decent. Is there such thing? I’ve tried biotin and all that hair skin and nails stuff and none of it seems to help. I just took off my acrylics that I’ve had on forever now and my nails are looking so sad ☹️
