Excellent supplement producer. I ordered Biotin supplements from Sports Research hoping to increase the health of my nails and hair. Within four weeks there was a very noticeable improvement in both nails and hair. I have continued to order this product because I finally have beautiful nails for the first time in my life! This product also stopped the thinning of my hair!
