What The FDA Has To Say
Any claims that you can lose weight effortlessly are false. The only proven way to lose weight is either to reduce the number of calories you eat or to increase the number of calories you burn off through exercise. Most experts recommend a combination of both.
When consumed in high enough amounts, for a long enough time, or in combination with certain other substances, all chemicals can be toxic, including nutrients, plant components, and other biologically active ingredients.
The term "natural" on labels is not well defined and is sometimes used ambiguously to imply unsubstantiated benefits or safety. For example, many weight-loss products claim to be "natural" or "herbal" but this doesn't necessarily make them safe. Their ingredients may interact with drugs or may be dangerous for people with certain medical conditions.
Dietary supplement manufacturers may not necessarily include warnings about potential adverse effects on the labels of their products.
A product recall of a dietary supplement is voluntary and while many manufacturers do their best, a recall does not necessarily remove all harmful products from the marketplace.
