Ephedrine has been shown to dramatically improve weight loss results. Clinical studies have proven that ephedrine beats out diet and exercise alone when it comes to losing weight.
As mentioned, despite the usefulness of ephedrine for those seeking to lose weight, ephedrine can be dangerous for some people.
The most common side effect of ephedrine is probably a generalized feeling of jitteriness or restlessness. As a stimulant, ephedrine can make you feel overly energized and lead to difficulties with sleep.
