There's no evidence that Lipovarin — a popular, nonprescription diet pill — promotes weight loss. In fact, this product may actually pose serious health risks.
Lipovarin contains the ingredient synephrine, a constituent of bitter orange. Synephrine is a stimulant similar to ephedrine, which is found in the herb ephedra. Safety concerns led to the removal of ephedra products from the U.S. market.
However, many manufacturers simply substituted synephrine in products that used to contain ephedra. These products, including Lipovarin, likely have the same serious health risks as ephedra products — including increased risk of stroke and heart attack.
Remember, there are no shortcuts to permanent weight loss. The foundation of every successful weight-loss program is a healthy diet and regular physical activity.
