Energy supplements are products consumed to increase feelings of energy and focus. They come in a variety of forms, some of which include drinks, pills and powders. A number of natural, plant-based alternative exist for boosting energy, many of which can be purchased over-the-counter for under $15.
Korean Ginseng
Panax (Korean) ginseng is a supplement derived from the root of the ginseng plant. It is included in a variety of over-the-counter energy supplements and may be taken in its natural form for increased energy and stamina.
Ginseng is an adaptogen, meaning it has the ability to help the body deal with stress more efficiently. According to a study by Marina Davydov and colleagues in the October 2000 issue of the "Journal of Ethnopharmacology," ginseng has antioxidant and immune-enhancing properties that may help protect against exposure to radiation and other physical stressors. It may be taken as a pill or brewed into tea for its energizing effects.
Coffee
Coffee is a well-known energy-boosting beverage popular for its ability to enhance alertness and fight fatigue. It is made from the roasted seeds of the coffea plant and contains caffeine, a mild stimulant. According to Science Daily, mid-life coffee drinking has been linked with a lower risk for developing dementia and Alzheimer's disease later in life.
Coffee is safe when consumed in moderation and can provide a temporary boost in energy and focus. Excessive coffee consumption may cause side effects like jitteriness, agitatation and insomnia. One cup of coffee contains approximately 120 milligrams of caffeine.
Tea (Camellia Sinensis)
Tea is a drink made from the leaves of the Camellia sinensis plant. It is available in many forms, including green, oolong, white and black, all of which come from the same plant. Tea is high in healthy compounds like antioxidants, polyphenols and minerals, such as manganese, selenium and zinc. It contains less caffeine than coffee and is therefore less likely to produce unwanted side effects.
Yerba Mate
Yerba mate tea comes from the Ilex paraguariensis plant and is a popular drink in South America. It differs from regular tea in that it contains several compounds from the xanthine family, including theobromine and theophylline in addition to caffeine.
Despite its relatively high caffeine content, yerba mate may be less likely than other caffeine-containing beverages to cause side effects due to its monoamine oxidase inhibiting properties. It is also high in magnesium, manganese and potassium.
Guarana
Guarana is a plant native to Brazil whose fruit is prized for its energy-enhancing effects. It is added to many energy drinks for its high caffeine content, which is about double that of coffee beans. While it is generally recognized as safe, guarana can cause side effects like jitteriness and insomnia when consumed in excess.
