Optimum Nutrition Essential Amin.O. Energy

Overview

Optimum Nutrition Essential Amin.O. Energy is a dietary supplement that combines amino acids with caffeine sourced from tea leaf and/or coffee bean. It is formulated for anytime use, with a focus on energy, alertness, and post-exercise recovery support rather than a single-purpose ingredient formula.

Each serving provides 9 grams, which is about 2 scoops, and the formula is designed to let users adjust intake based on their preferred energy level. The source describes mild, moderate, and intense options depending on whether 2, 4, or 6 scoops are used, with corresponding increases in amino acids and caffeine. The product contains 0 g of sugar and is flavored with both natural and artificial flavors.

This supplement also carries the Informed Choice quality assurance designation, meaning products bearing that logo are regularly tested for banned substances by the LGC Limited sports anti-doping laboratory. That makes the formula notable not only for its energy and amino acid profile, but also for its sports-focused testing program.
