Powerful
Brand: Xenadrine
Dr. Feb's Analysis
Scientific Mechanism
Xenadrine Powerful operates primarily through its key stimulant, Caffeine Anhydrous (1,3,7-trimethylxanthine). At a cellular level, caffeine acts as an adenosine receptor antagonist. By blocking adenosine, it prevents the onset of fatigue and promotes alertness. This triggers the release of adrenaline, which increases lipolysis—the breakdown of fat cells—freeing fatty acids for energy. The proprietary Xenadrine(R) Blend likely synergizes this effect, utilizing thermogenic properties to elevate metabolic rate and core body temperature, thereby burning more calories throughout the day.
Key Benefits
Key benefits include:
- Increased metabolic rate for efficient calorie burning

Usage & Safety
The label suggests taking 1 rapid-release capsule daily. However, the warning notes that one serving contains up to 2 capsules. Do not exceed the recommended dosage. Take with a full glass of water. Because of the high caffeine content (equivalent to 2 cups of coffee), avoid taking late in the day to prevent insomnia. Consult a doctor if you are sensitive to stimulants, have heart conditions, or are taking blood thinners. Discontinue use 2 weeks prior to surgery.
