Energy drinks may give you a boost when you're feeling fatigued, but they're doing no favors in terms of your overall health and wellbeing. While studies have linked the popular beverages to everything from heart problems to liver health issues, energy drink consumption in the U.S. has steadily risen in recent years, with the prevalence of energy drink consumption increasing significantly for young adults and adults between 2016 and 2019.

However, when it comes to your health, not all energy drinks are created equal. Read on to discover the worst energy drinks on the market, according to dietitians. And while you'll soon learn about these unhealthy energy drinks, know that there are options that dietitians approve of including in your diet, like The Best Energy Drinks For 2021.

Full Throttle

Packing large amounts of sugar and more than 10% of the average adult's recommended daily caloric intake, Full Throttle doesn't pass muster for many dietitians.

"The energy drink that gets to the top of my worst list is Full Throttle, which comes in at 220 calories and is packed with sugar. The carbohydrates found in this particular energy drink are all from sugar at 58 grams," says Trista Best, RD, a dietitian at Balance One Supplements.

That sugar-packed Monster Energy drink isn't likely to get any dietitian's seal of approval.

"A 16-ounce serving of Monster Energy contains 54 grams of sugar," says Holly Klamer, MS, RDN, a registered dietitian nutritionist with My Crohn's and Colitis Team. "This amount of sugar is more than double the recommended daily sugar intake for women—25 grams per day according to the American Heart Association." Klamer notes that it also exceeds the 36-gram RDA of sugar for men.
