Optimum Essential Amino Energy 30 serve
Optimum Nutrition Essential Amino Energy — 30 Servings
Essential AMIN.O. Energy is Optimum Nutrition's anytime-use amino acid and energy formula — a flexible, low-calorie option that combines 5g of essential and branched-chain amino acids with 100mg of natural caffeine from green tea and coffee bean per standard serving. With only 5–10 calories and zero sugar per serving, it functions as a light pre-workout, a mid-afternoon energy boost, or a between-meal recovery drink. The adjustable serving system — from 1 scoop (light energy) to 3+ scoops (pre-workout strength) — makes it one of the most versatile supplements in the category.

Key Benefits
- Flexible Amino + Energy Formula — Adjustable scoop dosing means you control the caffeine and amino acid level. Start at 1 scoop for a gentle lift, use 2–3 scoops as a light pre-workout, or go higher for a more substantial energy hit.
- 100mg Natural Caffeine at 2 Scoops — Sourced from green tea extract and coffee bean for a cleaner, less jittery energy profile than synthetic caffeine anhydrous at equivalent doses.
- 5g Amino Acid Blend — A full spectrum including BCAAs (leucine, isoleucine, valine), essential aminos, glutamine, taurine, citrulline, and tyrosine — supporting muscle recovery, blood flow, and focus.
- 5–10 Calories, Zero Sugar — One of the lowest-calorie functional supplements available. Fits any diet plan without measurable caloric impact.
- Anytime Use — Low enough in caffeine at standard serving to use mid-morning or early afternoon without disrupting sleep at bedtime.
Best For
- Athletes who want a light amino acid + caffeine supplement without a full pre-workout hit
- Between-meal use to support recovery and maintain a positive nitrogen balance
- Morning energy without the heaviness of a full pre-workout formula
- Those who want precise control over their caffeine dosing
Not Ideal For
- Athletes wanting a high-dose, fully-loaded pre-workout formula (consider a dedicated pre-workout for heavy training days)
- Evening use at higher scoop counts — natural caffeine content may still affect sleep

Who Is This For?
