It shocks me how many people will pop over-the-counter pills blindly without safety even crossing their minds. It’s a common belief that if something makes it onto a health food store shelf or is natural, it must be safe, but in fact, this is part of the naturalistic fallacy. Plants and other naturally-occurring substances can be poisonous. They can also be beneficial or neutral in low doses but harmful in a high dose. Individual tolerance may vary as well, as some people have allergies, take meds or have medical conditions.
Fair and balanced viewpoint on miracle diet pills here.
Stick with intake control and output maximization.
