A member asked:

I want to know if there are any side effects in using pre-workout , green coffee extract and fat burner supplements ?

A doctor has provided 1 answer

Yes: It depends on the make up of the fat burner supplement. Many over the counter weight loss supplements have stimulants in them. If taken in excess, they can cause palpitations, trouble sleeping, nervousness, etc... I generally do not recommend supplements to lose weight as most are unproven and the best way to lose weight and stay healthy is just plain diet and exercise in moderation.
