Take 1 capsule twice daily, 30 to 60 minutes before your two largest meals; avoid taking within 4 hours of bedtime. Because it contains caffeine, consider taking earlier in the day and limit other caffeine sources. Taking with a full glass of water may improve tolerance to cayenne.

Caffeine stimulates the central nervous system and increases catecholamines, which may enhance energy expenditure and fat oxidation.
Caution: May cause jitteriness, rapid heartbeat, or sleep disruption; avoid taking near bedtime and consider total daily caffeine from all sources.
Green coffee supplies chlorogenic acids that may influence glucose and fat metabolism, supporting use of fat for energy.
Caution: Contains natural caffeine and may interact with stimulant sensitivity; discontinue use if nervousness or palpitations occur.
Green tea catechins and natural caffeine may support thermogenesis by promoting norepinephrine activity and fat oxidation.
Caution: Contains caffeine and may contribute to insomnia or restlessness; take earlier in the day if sensitive.
Capsaicinoids may increase thermogenesis and perceived heat, modestly raising energy expenditure.
Caution: May cause stomach discomfort or a warming sensation; take with water and avoid on an empty, sensitive stomach.
L-theanine modulates brain neurotransmitters like GABA and alpha-wave activity, which may promote calm focus alongside caffeine.
Caution: May cause drowsiness in some individuals; assess personal response when combined with caffeine.
Caffeine and green tea catechins act on thermogenesis and fat oxidation, while green coffee’s chlorogenic acids influence how the body handles carbohydrates and fats. L-theanine helps smooth the stimulant effects of caffeine for focused energy, and cayenne provides a thermogenic nudge to caloric burn.
Label Warning: Adults only. Consult a healthcare professional before use if pregnant or nursing, have a medical condition, or use prescription medications. Contains caffeine roughly equal to one and a half cups of coffee per recommended dose; limit other caffeine sources to reduce risk of nervousness, irritability, sleeplessness, or rapid heartbeat. Allergen caution: manufactured on equipment that may process milk, eggs, soy, wheat, shellfish, fish, tree nuts, peanuts, and sesame.
Who should be cautious: People sensitive to caffeine, with sleep difficulties, heart concerns, anxiety, or high blood pressure may need extra caution. Those with liver issues should be cautious with green tea extracts. Individuals with gastrointestinal sensitivity may react to cayenne. If you take medications, especially stimulants or sedatives, discuss with a healthcare provider before use.

Double Your Weight Loss‡
There are hundreds of weight loss supplements on the market, but we think too many fail to deliver what they promise, and even more problematic, some cause you to lose the wrong type of weight - too much muscle and not enough fat.
LeanFire® is different. It contains Verilean®, a thoroughly studied, scientifically backed thermogenic ingredient, working to double your weight loss‡ while helping you burn more fat relative to muscle as part of your transformation. No one wants to lose 10 pounds and still look flabby.
Paired with this powerful ingredient is a precise combination of caffeine and L-theanine, giving you clear, smooth energy to help you overcome diet fatigue and suppress your appetite, with virtually no jitters and no crash. It's a scientific symbiosis we call thermovigilance®.
The result of LeanFire's carefully selected matrix of ingredients is weight loss without compromise. Now as part of your workouts, you can achieve the lean, sexy physique you crave in less time. LeanFire just works, and that's what you want.
In a clinical study, participants who took Verilean®, the key ingredient in LeanFire®, and maintained a low-calorie diet for 60 days lost an average of 10.95 lbs. The placebo group only lost an average of 5.4 lbs.
‡Results from a 60-day randomized, double-blind, placebo-controlled study of African green coffee bean extract (Coffea canephora)
