The Good Guide helps you find the best natural, safe, and organic products wherever you shop. For each product you can see a photo, and information on where it's rating came from. This rating comes from a variety or ratings including the ingredients of the product, the manufacturing process, and the ethical practices of the company.
You can also set up shopping and avoid lists for the stores you shop at. To do this you need to create an account at http://goodguide.com though.
If safe, natural, or organic products are important to you, the Good Guide is a fantastic reference.
