Optimum Nutrition Essential Amino Energy

Optimum Nutrition Amino Energy: 5 g of amino acids and 100 mg of caffeine

Optimum Nutrition Essential Amino Energy is a flavoured amino energy drink: each 2-scoop serving gives a 5 g blend of free-form amino acids and 100 mg of caffeine from green tea and green coffee extracts, with 5 calories and no sugar. Amino Energy is popular as a light pre-workout, a morning drink instead of coffee, or a tasty way to drink more water during training. The amino blend includes the three BCAAs plus glutamine, arginine, citrulline, beta-alanine and taurine. It suits adults who want a gentle caffeine lift without a heavy pre-workout.

What’s in a serving (2 scoops, 9 g)

Amino blend: taurine, L-glutamine, L-arginine, L-leucine, beta-alanine, L-citrulline, L-isoleucine, L-valine, L-tyrosine, L-histidine, L-lysine, L-phenylalanine, L-threonine and L-methionine. Sweetened with sucralose. Contains soy. Beta-alanine can cause a harmless tingling feeling.

Who it suits

• Light pre-workout: 100 mg of caffeine instead of a full-strength pre-workout.
• Coffee swap: a cold, fruity drink in the morning or afternoon.
• Calorie counting: 5 calories and zero sugar per serving.
• Comparing aminos: see caffeine-free options among our BCAA and EAA supplements.

How to use

Mix 2 scoops with about 300 ml of cold water. Start with one serving to see how you react to the caffeine; ON’s label allows more scoops for a stronger serving, up to 6 scoops in any 4 hours and 10 scoops (500 mg caffeine) a day; keep your total caffeine from all sources within 400 mg a day. Each serving has 100 mg of caffeine, so count it with coffee, tea and energy drinks. Not for under-18s, pregnancy or breastfeeding, or people sensitive to caffeine.

Amino Energy questions

How much caffeine is in Amino Energy?

Each 2-scoop (9 g) serving has 100 mg of caffeine from green tea and green coffee extracts, about the same as a small cup of coffee. Count it with your other caffeine for the day.

When should I drink Amino Energy?

Any time you want a light lift: in the morning, about 30 minutes before training, after training, or in the afternoon. Avoid it in the late evening if caffeine affects your sleep.

Is Amino Energy a pre-workout?

It is a lighter alternative. With 100 mg of caffeine and no sugar per serving it gives a gentle lift, while most pre-workouts carry 200–350 mg of caffeine plus pump ingredients. ON’s label allows more scoops for a stronger serving, but no more than 6 scoops in any 4 hours or 10 scoops in a day.

What is the difference between Amino Energy and Amino Energy + Electrolytes?

Both give 5 g of amino acids and 100 mg of caffeine per serving. The + Electrolytes version adds electrolytes for long or hot sessions; the original Amino Energy has none and comes in a 270 g tub.

Does Amino Energy break a fast or add calories?

Each serving has 5 calories, 1 g of carbohydrate and no sugar, so it adds very little to your day. Food supplements don’t replace a varied diet. If you’re pregnant, breastfeeding, under 18, taking medication or have a medical condition, ask your doctor first.
