But are these drugs excellent medication, or even a waste of money?
"Nutritional supplements are never a substitute for the well balanced, healthful food plan," claims Dr. JoAnn Manson, a professor of drugs at Harvard Health care University and professor of epidemiology at Harvard's T.H. Chan School of General public Well being. "And they may be a distraction from healthful Life-style tactics that confer A lot bigger Positive aspects."
