Are these magic-pill claims grounded in science, fairy tales, or somewhere in between? Here’s our guide to the new pop culture.

Workout Supplements Gone Wild
The A-Roids of the world aren’t the only ones enhancing performance with pre-workout supplements. Thanks to guarantees of unbridled power, faster muscle recovery, and a talk-of-the-gym body, “everyone is using them,” says Drew Prinz, a clinical nutritionist. But their effectiveness and safety (or lack thereof) are worth a second thought. Stimulants lend energy and focus; vasodilators boost circulation and, therefore, aerobic capacity; and amino acids supercharge endurance. “If you usually do four sets, you will—and then four more,” Prinz says.
But many contain banned components. One popular ingredient is illegal: The amphetamine-like stimulant DMAA has been linked to at least five fatal cardiac arrests, with the FDA trying to seize products, like Jack3d and OxyElite PRO, from warehouses. In general, “juicing masks what your body is supposed to feel,” says Stoler. Indulging anyway? N.O.-Xplode, the first on the scene, “still has the best reputation,” Prinz says.

The Truth About Powdered “Greens”
Green mixes, those dehydrated herbs and veggies, purport to boost vigor, vitality, and virility. Should you drink up?
The Pros
They’re convenient, with a longer shelf life than anything you’ll find in the produce aisle, and they make it easy to amp up variety. Kamut, anyone?
The Cons
Many minerals and much of the fiber are lost in processing, along with enzymes needed to absorb nutrients. Also, beware of fillers, including artificial sweeteners and, in some cases, heavy metals and pesticides. Avoid InnerLight Super Greens, which failed a recent ConsumerLab.com investigation for high levels of lead; Vibrant Health Green Vibrance (arsenic); and The Ultimate Meal (bacteria).
The Verdict
Vegetable powders are better than no vegetables at all. Try stirring a GMO- and gluten-free formula, like Athletic Greens, into hot cereal with goji berries.
