I am 22 years old and I just starting taking these vitamins a few weeks ago to help boost my immunity and help my hair, skin, and nails grow. At times, I’ve felt fatigued and I’ve noticed that I get sick quite often. In the past few weeks, I haven’t gotten sick and I did notice that my nails were growing a bit stronger. I’m hoping that over time these will continue to work and help my body stay healthy. I purchased these at Target and they were averaged priced for these vitamins. I recommend giving these a try if you’re a woman looking to try new vitamins!
