Kirkland Signature Extra Strength Energy Shot is a convenient, low-calorie, zero-carb energy supplement designed to deliver fast-acting, sustained energy for both mind and body. Each 2 fl oz shot contains 230 mg of caffeine along with a 2,110 mg proprietary energy blend — providing more caffeine than a standard cup of coffee in a pocket-sized, easy-to-take bottle. The formula is sugar free, gluten free, and USP verified for quality and purity.

Each box includes 48 individual shots — 24 Berry flavor and 24 Blue Raspberry flavor. The energy blend contains amino acids L-Tyrosine, Taurine, and L-Phenylalanine, as well as brain-supporting nutrients Glucuronolactone and Alpha Glycerylphosphorylcholine. B vitamins including Niacin (B3), B6, B12, and Folic Acid support carbohydrate energy metabolism for both mental and physical performance. With zero sugar and zero carbs, the shots deliver hours of energy without a post-energy crash.

For maximum energy, drink one entire bottle at once. For moderate energy, drink half a bottle or less. Do not consume more than two bottles per day, spaced several hours apart. Persons sensitive to caffeine should use with caution. Not for use by pregnant or nursing individuals or those under 18 years of age. Phenylketonurics: contains L-Phenylalanine.
