Supplements are so prevalent here in the United States that they have their own storefronts, loyal fan-bases, and are even touted across cable networks due to their popularity. Scientific evidence shows that some of these are beneficial to our overall health, but on one condition- they are most effective in conjunction with overall healthy behavior like diet and exercise. You can't take a magic diet supplement, for example, and expect to lose weight, all while pounding cheeseburgers and beer (wouldn't that be AWESOME?). So, in order to get the most out of your supplements, you need to support it with a healthy lifestyle.
