Caffeine - Nutrakey (100 Capsules)



Caffeine, a xanthine alkaloid compound, is known for its stimulating effects on the central nervous system, temporarily increasing alertness. It is widely consumed and considered a legal psychoactive agent. Found in various plants such as guarana berries, mat, chocolate or cocoa, tea leaves, and kola nut, caffeine may also coexist with other stimulants like theophylline and theobromine.

Key Features:

  • Enhances mental alertness and cognitive function.
  • Increases muscle strength and endurance.
  • Boosts energy levels.
  • Aids in increasing metabolism and promoting fat burning, which is why it is commonly found in many diet pills.


Caffeine's Role in Fat Burning:

Caffeine can be a valuable ally in reducing body fat percentage. It increases the level of free fatty acids in the bloodstream, making it easier for the body to use fat as a fuel source. Studies have shown that caffeine intake can lead to a significant increase in plasma-free fatty acids, and it enhances the rate of fat oxidation during aerobic activities. Some research has reported a 50% greater fat oxidation in individuals who consumed caffeine before exercise.

Caffeine's Impact on Performance:

Besides promoting fat burning, caffeine can also improve total aerobic capacity. During aerobic activities, the body relies on both fat and glycogen (sugar) for energy. By consuming caffeine, the level of free fatty acids in the blood rises, resulting in a "glycogen-sparing" effect. This means that the body uses more fat as fuel, delaying the depletion of glycogen stores and reducing fatigue. Consequently, caffeine can prolong exercise duration and improve overall performance during aerobic activities.

It's important to note that while caffeine may offer these benefits, individual responses to caffeine can vary. As with any dietary supplement, moderation and personal considerations are crucial. It's recommended to consult with a healthcare professional before making significant changes to your caffeine intake or exercise regimen.
