Detox

Your body does a fine job of detoxing itself. There is absolutely no need to purchase some sort of 'detox', which is usually a bunch of useless supplements for use in a modified fast. They are gimmicks.

You'd be better off buying some healthy food, a gym membership, new running shoes, etc.

Hi there... Not only have I read about them but I have done several. Kits can be confusing (so many to chose from) and expensive and may not address your personal needs. There is an extremely large book called Prescription for Nutritional Healing, I have the Fourth Edition. It is a practical A-Z reference to drug-free remedies using vitamins, minerals, herbs & food supplements, by Phyllis A. Balch, CNC. A friend of mine is a nurse and she recommended it so our family has been using it for quite some time and love it! Also it's not expensive! Try Amazon ; - ) or the local library.
Having said that, there is some great advise about detoxing, which I found helps get your organs going on the right track. I think it's imperative to your health personally.
Hope the book helps, it has a world of information in it.
Good luck...
