5hour

5hour is a brand name most commonly associated with 5-hour Energy, a caffeinated energy shot that originated in the United States in the early 2000s. The product is marketed as providing five hours of energy from a small 2-ounce bottle and is produced by Living Essentials LLC. The term “5hour” is an informal rendering of the product’s branding.

Product characteristics: The standard shot delivers approximately 200 mg of caffeine per serving and includes a B-complex vitamin blend along with amino acids such as L-tyrosine. It is advertised as sugar-free and calorie-free, using artificial sweeteners. It is sold in multiple flavors and formulations, including original and extra-strength variants.

Usage and regulation: 5hour is sold as a dietary supplement rather than a drug, and labeling is not evaluated by the FDA for efficacy. Consumers are advised not to exceed one shot per day and to avoid use by children, pregnant or nursing individuals, or people sensitive to caffeine.

History and market presence: Living Essentials LLC introduced the product in 2004; it became a leading energy-shot brand in the United States. The brand has expanded distribution and diversified its product line with several flavors and versions to maintain consumer interest.

Safety notes: As with other high-caffeine products, excessive consumption can cause jitters, insomnia, caffeine dependence, or heart-related effects in susceptible individuals. Users should consult a healthcare professional if unsure about interactions with medications or medical conditions. See also energy drinks, caffeine, and dietary supplements.
