I love country life biotin from Vitamin Shoppe. The capsules are tiny enough to take without water!
I use Trader Joe's Multi...but lately I've been taking Green Vibrance (from Iherb). It's a green drink that is supposed to be more readily absorbed by the body, and have health benefits as well as hair, skin and nail benefits! I'll let you know my results...I've been taking it for a week now.
