Caffeine is an energy booster and focus enhancer. It can be found in coffee, tea and energy drinks; with coffee being one of the more traditional beverages dating back centuries and energy drinks more recently appearing at gas stations and convenience stores.

Coffee and energy drinks both contain caffeine, but there are significant distinctions between them. Energy drinks contain more sugar and artificial ingredients than their coffee-related counterparts, leading to an unhealthy sugar crash after their initial boost of energy has worn off. Furthermore, high levels of sugar consumption have been linked with weight gain as well as an increased risk for heart disease and type 2 diabetes.

Traditional coffee is composed of roasted beans, water and cream; although some individuals add sugar, most do not. There are even low-cal options such as those sweetened with all-natural stevia or non-dairy creamers which provide sweetening without adding to caloric intake. Furthermore, coffee contains antioxidants which protect against disease as well as lower the risk of heart conditions; its caffeine is slowly absorbed into the bloodstream to provide sustained energy without sudden surges and drops experienced with energy drinks.

Consumption of too much caffeine can increase heart rate and blood pressure. Furthermore, it may contribute to anxiety and depression; however if consumed in moderation it is generally safe for most healthy adults.

Some individuals may be more sensitive to caffeine than others, which could be the result of food and beverage intake or medical conditions like pregnancy or heart problems. It would be prudent for such individuals to monitor their caffeine consumption carefully and contact their healthcare provider if any concerns arise.

Coffee may contain more calories than an energy drink, but it still comes out ahead in comparison with many flavored or sugary drinks sold at Starbucks and cafes. Specialty beverages can contain high levels of added sugars that make it hard to monitor how much you are consuming at one sitting; the best choice for those trying to reduce sugar consumption would be black coffee with organic beans for a more sustainable source of caffeine without added sugars or artificial ingredients like most energy drinks; furthermore it may offer additional health benefits including lower disease risks and a boost of antioxidants intake.
