Description

Optimum Nutrition Amino Energy + Electrolytes combines a powerful blend of essential amino acids with naturally derived caffeine and key electrolytes to fuel your energy, focus, and recovery. Engineered for active New Zealanders who need an extra edge in the gym, on the field, or during a demanding workday, this versatile formula delivers clean energy without the heavy crash.

Key Benefits & Features

  • Essential Amino Acid Support: Delivers 5g of micronised free-form amino acids, including BCAAs, to support muscle recovery and lean tissue preservation.

  • Natural Energy & Focus: Contains 100mg of caffeine per serving sourced from green tea and green coffee bean extracts for a smooth, reliable performance boost.

  • Optimal Electrolyte Hydration: Formulated with essential minerals like sodium, potassium, and magnesium to replace lost electrolytes during sweat-heavy sessions.

  • Versatile & Customizable: Adjust your serving size to suit your energy needs—from a mild morning pick-me-up to an intense pre-workout kick.

  • Zero Sugar & Low Calorie: Designed to support lean fitness goals while delivering refreshing, high-quality flavour with zero guilt.

How It Works

Physical exertion depletes vital amino acid reserves and essential electrolytes through sweat, leading to premature fatigue and slowed muscle recovery. Optimum Nutrition Amino Energy + Electrolytes directly addresses these performance bottlenecks by supplying free-form essential amino acids that are rapidly absorbed to initiate muscle repair.

The inclusion of naturally sourced caffeine provides sharper mental focus and sustained stamina, while potassium, sodium, and magnesium work synergistically to maintain optimal fluid balance and cellular hydration. Whether used as an intra-workout intra-hydration drink or an afternoon energy booster, it keeps your body hydrated and your performance peak.

Recommended Use

Mix 2 scoops (approx. 9.5g) with 300–350ml of cold water. Consume 15–30 minutes prior to training for pre-workout energy, or sip throughout your workout to support hydration and amino acid delivery. For a daytime energy boost, take 2 scoops in the morning or early afternoon. Do not exceed 6 scoops within any 24-hour period.

Optimum Nutrition Amino Energy + Electrolytes Frequently Asked Questions

What is Optimum Nutrition Amino Energy + Electrolytes and how does it work?

Optimum Nutrition Essential Amino Energy + Electrolytes is a highly versatile, refreshing daily performance powder. It functions as an all-in-one matrix by combining a 5g micronised amino acid blend to support muscle conditioning and post-workout recovery, 100mg of caffeine from natural sources to sharpen mental focus, and a targeted electrolyte complex to help restore vital minerals lost during intense physical exertion or daily activity. 

What specific electrolytes are included, and why do they matter?

Each standard serving features an advanced 405mg to 440mg hydration blend consisting of Sodium Chloride, Potassium Chloride, and Magnesium Oxide. When mixed with water, these ionic elements support optimal cellular hydration and fluid balance. They help replace the critical mineral salts lost through sweat, ensuring smooth muscular function and physical endurance during long, high-sweat training sessions.

What are the exact macronutrient and caffeine metrics per serving?

Every standard 2-scoop serving (approx. 9.5g) delivers an exceptionally clean, macro-friendly profile that replaces sugary ready-to-drink energy cans:

Amino Acids: 5g of micronised aminos (including Essential Amino Acids and BCAAs like L-Leucine, L-Isoleucine, and L-Valine).

Natural Caffeine: 100mg derived cleanly from Green Tea Leaf and Green Coffee Bean extracts.

Macros: Only 5 to 10 calories, zero fat, zero carbohydrates, and completely sugar-free.

Can I adjust the serving size based on my personal energy needs?

Yes. One of the greatest features of this powder is its fully customizable dosing structure: 

The Afternoon Pick-Me-Up (2 Scoops): Delivers 100mg of caffeine and 5g of aminos—ideal for replacing an afternoon coffee or clearing a midday mental slump.

The Pre-Workout Performance Boost (4 Scoops): Supplies 200mg of caffeine and 10g of aminos to prime energy levels and focus before stepping onto the gym floor.

The Intense Training Matrix (6 Scoops): Provides a heavy-duty 300mg caffeine burst and 15g of aminos for your most grueling endurance or resistance sessions. Do not exceed 6 scoops within a 24-hour window.

Does this product contain Beta-Alanine, and will it cause a tingling sensation?

Yes, the amino blend includes premium Beta-Alanine (as CarnoSyn®), an amino acid that assists in buffering lactic acid accumulation within exercising muscle tissue to reduce physical fatigue. Because it features Beta-Alanine, first-time users or those sensitive to the ingredient may experience a mild, temporary tingling sensation on the skin (known as paresthesia). This is a completely harmless, natural physiological reaction that wears off quickly.

How many servings are in a standard tub?

A standard full-size container has a net weight of 285g and provides exactly 30 full servings based on the standard 2-scoop metric (60 individual scoops total per tub). This format delivers outstanding long-term value for daily fitness enthusiasts.

What are the top-rated customer flavors available at Sprint Fit?

Optimum Nutrition is world-famous for its crisp, light, and fruity flavor profiles that mix completely clear without any chemical aftertaste or chalky residue. High-selling consumer favorites across New Zealand include Strawberry Burst, Pineapple, Tangerine, Watermelon, and Sun-Kissed Citrus.

Love it. Has really helped my training. Great taste, very thirst quenching. The container is a little wasteful - the powder barely fills a quarter of it.

Pineapple has a nice flavour and is easy to take. I think it’s a good product but wish there was one without caffeine so I could take later in the day

Very good I got watermelon and flavour is great! Does not give you a huge effect as it is kind of low in caffeine! Which is amazing and what I was looking for you don’t feel tired a few hours later after consuming like other ones!
