Three major studies published in recent weeks disprove the effectiveness of some of the most profitable pharmaceutical drugs. The risks of antidepressants in children and teens far outweigh the benefits, as the drugs routinely increase suicidal behavior. Scientists are also reporting that cholesterol drugs, which 15 million Americans are prescribed, are completely worthless. A third major study found that giving children multiple vaccines at once is unsafe. The studies underline that there may be no better medication than a healthy lifestyle.
