I started taking vitamin supplements when a friend of mine told me that they would keep me healthy. But after sometime, I noticed that was feeling tired and dizzy easily. When I consulted a doctor, he found that I was consuming more than the required amounts of vitamins. He asked me to move over to customized vitamins and supplements as it would ensure that right amount of vitamins are consumed. Additionally, these custom made vitamins are tailor made for me, for my specific health concern. Now I lead a normal life and I do not suffer from any side effects.
