enXtra is a patented version of Alpinia galanga root, a member of the turmeric family used in southeast Asian cuisine for generations.

enXtra acts on dopamine and has been shown to:

• Support alertness better than caffeine for up to 5 hours†
• Assist with mental energy†
• Promote a feeling of calm†

Often studied in combination with caffeine, enXtra may help to reduce the energy crash associated with caffeine use.† However, unlike caffeine, it has not been found to have an effect on the sleep-wake cycle, and does not lead to the consequences that occur after cessation of consistent caffeine use.†

When you consume caffeine, it breaks down into different metabolites. enfinity is a branded version of the metabolite paraxanthine. Because it comes from caffeine, paraxanthine offers many of caffeine’s famous properties.

Paraxanthine has been shown to:

• Promote dopamine levels†
• Support a positive mood†
• Help provide steady energy—no jitters†
• Help maintain brain function†
• Promote energy expenditure†

One trial indicated that paraxanthine may be better for mental performance than caffeine alone.†

Because paraxanthine has a shorter half-life than caffeine, it clears your system faster. That means you get the energy you want when you need it, and when your work and your day are done, the effect wears off, so there’s little reason for it to interfere with sleep.† 

Furthermore, unlike caffeine, there are none of the effects you hate. No “caffeine crash” or other lingering unpleasant feelings that result from caffeine’s downsides.

Certified by Informed Ingredients, enfinity is guaranteed pure and free of banned substances.

Derived from mango leaf (Mangifera indica), Zynamite is non-stimulating. It works by helping to stop the breakdown of dopamine, supporting overall levels.

Zynamite has been shown to:

• Support mental and physical energy†
• Promote reaction time†
• Help decision-making†
• Support muscle endurance and power output during exercise†
• Help buffer against the sensation of muscle “burn” during exercise and post-workout muscle soreness†

Despite its impact on exercise performance, Zynamite has not been shown to have any effect on heart rate. Zynamite appears along with the polyphenol quercetin in Korrect ENERGY, as research indicates quercetin can augment Zynamite’s physical performance benefits.†

The polyphenols in both green coffee and green tea are known to have metabolic benefits independent of caffeine. Both are currently being studied for a possible synergistic effect with paraxanthine and are showing promising results in preliminary trials.

Korrect Edge is sweetened with Glyvia™, a natural, zero-calorie sweetener shown to support healthy glucose metabolism and healthy blood glucose levels.† It dissolves easily into water to help you power up with a delicious, sugar-free mango fruit flavor.
