Before you answer this question you need to know the difference between the two.
Herbal weight loss supplements are natural and, for the most part, non toxic. They contain several bioactive constituents that work together to establish an overall state of wellness and balance. Although they have greatly aided a myriad of people to lose weight, they are not guaranteed to have the same degree of success to everyone.
Weight loss drugs are synthetic chemicals designed specifically for weight loss. They have gone through a rigorous review process, before being approved by the FDA, that guarantees their efficacy. However, as with all drugs, some unpleasant side effects may be associated with their usage.
a. I would consider taking an over-the-counter weight loss drug, provided it has minimal side effects and is doctor and FDA approved.
b. I want to avoid taking drugs even if they are FDA approved. I am looking for a high quality herbal supplement that contains all natural ingredients and has been studied for its effectiveness in weight loss.
