Beware of this label. It is one of the most unclear and falsified labels. This label is used by some to mean that no artifical or synthetic ingredients have been added to a product.This label is used by most to describe that the product is more wholesome or healthy than other products. However you can find natural juices made from GMO fruits and GMO corn syrup. You can buy clothes made from natural fibres but sprayed with harmful chemicals such as formaldehyde.

Actually, until May 10, 2016, you can join thousands to submit your comments to the FDA (U.S.) on how the natural label should be used and defined. 

"The FDA is taking this action in part because it received three Citizen Petitions asking that the agency define the term “natural” for use in food labeling and one Citizen Petition asking that the agency prohibit the term “natural” on food labels. We also note that some Federal courts, as a result of litigation between private parties, have requested administrative determinations from the FDA regarding whether food products containing ingredients produced using genetic engineering or foods containing high fructose corn syrup may be labeled as “natural.” 

 

 Any product labelled as natural requires extra scrutiny by any consumer to determine whether ingredients may cause health issues for you.
