Hi Tammy!
I take Biotin 1000mcg every day. I have psorias and have pitts in my nails and let me tell you it has helped and they are actully growing again. I used to have beautiful nails and now they are beautiful again!
You can buy it at Walmart - the Rexall brand is only $4.99 for 120 pills....
Good luck!
