What is Natural Coffee Bean Caffeine?
Manufacturers can synthesize caffeine from urea and chloroacetic acid, or they can extract it from coffee beans.
Natural coffee bean caffeine comes from the fruit of the Coffea arabica plant. Natural and synthetic
caffeine produce nearly indistinguishable effects, as they have identical chemical structures.
What Does Caffeine Do?
Caffeine is an alkaloid found in coffee beans, tea leaves, and cocoa plants. Its primary role is to stimulate the
central nervous system (CNS) and delay drowsiness. It achieves this by blocking adenosine, a compound that occurs
when the body breaks down adenosine triphosphate (ATP) for energy. As adenosine accumulates, it interacts with its
receptors to induce sleepiness. Caffeine attaches to adenosine receptors in a similar manner to inhibit this
Potential Coffee Bean Caffeine Benefits
Caffeine Pure for Energy
Many individuals consume caffeine for its energy-boosting properties. Some common caffeine sources include
coffee, energy drinks, soda, tea, and chocolate. However, it’s difficult to measure caffeine levels in many
dietary sources. Taking caffeine supplements provides better control over dosages and yields more consistent
results. Caffeine’s ability to block adenosine boosts energy levels in two ways. Adenosine can’t interact with its
receptors, which delays tiredness. It also boosts dopamine levels, which helps increase energy levels while
Caffeine Pre-Workout and Weight Management Benefits
Many pre-workout products contain caffeine to increase energy and enhance physical performance. It increases
endurance levels, enhances power output, and decreases the perception of physically taxing exercises. Unlike some
supplements, people of all ages, fitness levels, and body compositions can benefit from taking caffeine before a
workout. Caffeine also interrupts fat storage and increases metabolic rate, which can help individuals continue to
burn calories outside of exercise. Individuals are also more active after consuming caffeine, as they have more
energy and less fatigue.
Caffeine and Theanine for Focus
Caffeine can significantly boost cognitive function in individuals who don’t consume caffeine regularly. However,
those who consume caffeine often can experience cognitive enhancements by combining caffeine and l-theanine.
L-Theanine is an amino acid found in tea, with the greatest concentrations in green tea. A caffeine and l-theanine
combination improves focus, facilitates attention switching, increases alertness, and allows individuals to
disregard distractions. L-Theanine dulls the stimulatory edginess of caffeine without impeding alertness, and it
may diminish caffeine-induced nighttime sleeplessness.
Caffeine Side Effects
Individuals that don’t consume coffee are more likely to experience mild caffeine side effects, such as jitters,
bowel urgency, and digestive upset. Consuming caffeine in the afternoon can cause difficulty sleeping. Individuals
that are pregnant, nursing, or have a history of heart disease should not take caffeine supplements. Consult your
physician before taking caffeine supplements.
