I've been on the vitamins for six weeks and have noticed improvements in my hair, skin, and surprisingly my health. I have a high risk for breast cancer and visit a doctor every six months to keep track of breast pain. Since being on the vitamins I have not had as much (virtually none) pain in them (breast). The doctor asked what I was doing different and I mentioned I had started taking VitaStrand. He thought they may have contributed to the improvement I noticed in my breast. My hair is growing, my nails are healthy, and my skin is beginning to clear up. …my health has benefited.
