If your physique goals need a little fine-tuning, you may find yourself seeking help in the supplements aisle. While there, look for these key ingredients, which have proven benefits when it comes to increasing fat burn and revving metabolism. 

GREEN COFFEE-BEAN EXTRACT 

Also known under its scientific name, Coffea canephora robusta, this well-studied fat burner has ample research to back its benefits. One study showed that subjects supplementing with this ingredient lost almost 11 pounds in 60 days. Research also shows that green coffee-bean extract contains a compound called chlorogenic acid, which boosts fat metabolism in your liver. 

CAFFEINE ANHYDROUS 

Caffeine provides many advantages for hard-training women who are trying to control or reduce body fat. It works by encouraging your body to release stored fat that it can then use for energy while training. Caffeine also helps to boost your metabolism, so you burn more calories throughout the day, and helps suppress appetite while enhancing mood. At the gym, caffeine improves the amount you’re able to lift by helping reduce perceived pain (and exhaustion). Caffeine anhydrous—the dry form of caffeine—has been shown to be more effective for fat loss and strength gains compared with caffeine found in coffee and tea. 

COLEUS EXTRACT 

This herb, also known as forskolin, has long been used in traditional medicine. A powerful fat burner, it stimulates your brain to increase the neurotransmitters epinephrine and norepinephrine. These brain chemicals then encourage your body to release stored fat. In addition, the release of these hormones also helps increase your metabolic rate, or the amount of calories your body naturally burns each day. 

Putting It All Together

Hydroxycut Hardcore Next Gen from MuscleTech features all of these key ingredients to help improve weight loss, boost energy, and improve focus. Each two-capsule serving contains 400mg of a green coffee-bean extract blend, 290mg of caffeine anhydrous, and 100mg of Coleus extract. Because tolerance varies, MuscleTech recommends the following dosing: Take one capsule one time daily for the first two days, then two capsules as one dose on Days 3 and 4, followed by two capsules with your first dose and one capsule with a later dose on Days 5 and 6. Take two capsules with two doses on Days 7 and beyond. Take each dose 30 to 60 minutes before your two largest meals; don’t take for more than eight weeks at a time.
