I absolutely love Soure of Life Vitamins. I was always fatigued and my nails and hair didn't grow. In fact, my hair was faliing out and fast. I have a variety of health challenges and was looking for supplements that will help me feel better. I never expected to find it all in one bottle. My nails grow so fast. I'm constantly cutting and trimming them. My hair is so healthy and soft. I just cut the split ends a few days ago. Can you believe it! My hair is actually growing. I am very pleased.
