I am one of those people who doesn't care for western medicine so much. I am learning to be proactive and preventative. I research a great deal but nothing compares to practical application. It is hard to monitor the effectiveness of each product specifically but it is often times better to remove things and see if there is a decline or taking the less is more approach to find out what really works for you. We all have problems, Iherb has provided me with a great tool to increase my quality of life. I thank iherb and the community for helping make the world a better place. If you desire change , take action.
