What Does Caffeine Do?
Caffeine is the primary alkaloid found in green and roasted coffee beans. Common dietary sources include coffee, tea, soda, energy drinks, and chocolate. It stimulates the central nervous system and the autonomic nervous system to prevent drowsiness. Caffeine’s most recognized mechanism of action is temporarily blocking adenosine from entering its receptor. Adenosine makes the body aware of drowsiness, and blocking its receptor induces alertness.
Caffeine is best known for its stimulant properties, but it is also a notable nootropic, performance enhancer, and fat burner. It also supports longevity. Caffeine synergizes with other supplements to enhance the benefits of both.
Potential Caffeine Benefits
Many people start their day with coffee to boost their energy and ward off drowsiness throughout the day. However, caffeine has several other beneficial properties.
Caffeine and Energy Levels
Caffeine boosts energy lives while simultaneously combating fatigue. Blocking adenosine serves two functions. It prevents adenosine from signaling drowsiness, and it increases levels of dopamine. Dopamine helps regulate energy and decrease fatigue.
Pre-Workout Caffeine Benefits
Caffeine is a popular ingredient in pre-workout supplement blends. In addition to boosting energy levels, it enhances athletic performance. Numerous studies have shown that consuming caffeine before exercising increases peoples’ endurance while decreasing their perception of physical exertion. Caffeine enhances physical performance in both younger and older adults, regardless of age, existing fitness levels, and fat levels. Some individuals also experience an increase in their power output following caffeine consumption.
Caffeine as a Fat-Burner
Caffeine increases metabolic rate, which allows individuals to burn more calories while at rest. Caffeine also disrupts typical fat storage while supporting healthy gut microbiota. Caffeine also increases the likelihood of individuals meeting their recommended physical activity levels by boosting energy and reducing fatigue.
Caffeine and Cognition
Caffeine’s cognition-enhancing potential is particularly notable among those who don’t regularly consume caffeine. However, daily coffee drinks can still reap cognitive benefits by combining caffeine with L-Theanine.
Caffeine and L-Theanine
L-Theanine is an amino acid found abundantly in green tea. It works with caffeine to improve alertness, attention switching, and focus by reducing susceptibility to distractions. L-Theanine modulates the stimulatory side effects of caffeine without inhibiting alertness. L-Theanine may reduce caffeine-related sleep disturbances as well.
Other Caffeine Benefits
Caffeine supports the healthy functioning of numerous organs, including the liver and the heart. The cumulative benefits of caffeine also have the potential to enhance longevity. Caffeine also has antioxidant properties that may enhance overall health.
Potential Caffeine Side Effects
Caffeine supplements may cause mild side effects, which are more likely in individuals that do not regularly consume caffeine. These include upset stomach, bowel urgency, and jitters. Caffeine supplements may interfere with sleep if taken later in the day.
