Nutrex EAA ingredients provide an 8-gram full-spectrum essential amino acid matrix, featuring 6 grams of 2:1:1 BCAAs alongside 1.5 grams of hydration electrolytes. In Singapore, athletes use this stimulant-free formula to accelerate muscle protein synthesis, combat dehydration during humid gym sessions, and sustain intra-workout endurance without artificial crash.
Understanding the specific ingredients on a supplement facts panel separates clinically dosed training fuel from underdosed flavoured powders. Nutrex Research engineered EAA+ Hydration specifically for athletes who train intensely in warm environments. Whether you lift at fitness centres in Jurong, train outdoor calisthenics in Tampines, or run conditioning circuits in Bishan, maintaining amino acid saturation and fluid equilibrium dictates performance.
What Are Nutrex EAA Ingredients? Quick Label Breakdown
Nutrex EAA+ Hydration combines nine essential amino acids with an advanced hydration matrix, raw coconut water concentrate, and the patented absorption enhancer AstraGin. Unlike standard BCAA supplements that provide only three amino acids, this complete formula delivers all nine compounds the human body cannot produce on its own.

Here is the exact supplement facts breakdown per single 13-gram scoop:
- Total Essential Amino Acids (8,000 mg):
- L-Leucine (3,000 mg): The primary trigger for muscle protein synthesis through the mTOR metabolic pathway.
- L-Isoleucine (1,500 mg): Supports muscle glucose uptake and cellular energy production during lifting.
- L-Valine (1,500 mg): Helps prevent exercise fatigue and assists muscle tissue repair.
- L-Lysine HCl (885 mg): Supports structural collagen formation, tendon integrity, and immune defense.
- L-Threonine (520 mg): Facilitates nutrient absorption and protein balance in structural tissues.
- L-Histidine HCl (336 mg): A biological precursor to carnosine, buffering intracellular lactic acid accumulation.
- L-Phenylalanine (140 mg): Precursor to tyrosine and vital neurotransmitters supporting training focus.
- L-Methionine (75 mg): Supports sulphur metabolism, natural detoxification, and tissue regeneration.
-
L-Tryptophan (44 mg): Essential precursor to serotonin, balancing mood and stress recovery.
-
Hydration Complex (1,500 mg):
- Taurine (1,000 mg): Regulates intracellular water balance, cardiovascular function, and muscular contraction.
- Calci-K (345 mg): A patented calcium-potassium phosphate citrate complex delivering bioavailable minerals.
- Raw Coconut Water Concentrate (100 mg): Provides organic electrolyte trace minerals to restore cellular osmotic pressure.
-
AstraGin (50 mg): Plant extract compound clinically researched to increase intestinal absorption of amino acids.
-
Mineral Electrolytes:
- Calcium (60 mg): Essential for neuromuscular signal transmission and peak muscle contraction.
- Phosphorus (30 mg): Supports cellular ATP replenishment during high-intensity training.
- Magnesium Glycinate (20 mg): Bioavailable chelated magnesium preventing cramping and muscle spasms.
- Sodium (from Sodium Bicarbonate, 90 mg): Replaces primary sweat sodium loss and supports fluid retention.
-
Potassium (50 mg): Maintains electrolyte equilibrium and cellular membrane potential.
-
Inactive Ingredients: Citric acid, natural and artificial flavours, maltodextrin, silica, sucralose, and acesulfame potassium.
The 8g Essential Amino Acid Profile Explained
Essential amino acids (EAAs) are physiological compounds that the body cannot manufacture endogenously. While branched-chain amino acids (BCAAs) cover leucine, isoleucine, and valine, human muscle protein synthesis requires all nine EAAs simultaneously. Supplying only BCAAs without the remaining six EAAs limits systemic tissue reconstruction, because protein synthesis stalls as soon as any single essential amino acid depletes.
The 6-gram BCAA core inside Nutrex Research EAA Hydration adheres to the researched 2:1:1 ratio. Providing 3,000 mg of pure L-Leucine per scoop crosses the established 2.5 to 3-gram leucine threshold required to activate mTORC1 (mechanistic target of rapamycin complex 1). This metabolic trigger signals ribosome biogenesis and initiates new myofibrillar protein synthesis.
Meanwhile, the supporting 2,000 mg of non-BCAA essential aminos provides the biological building blocks to sustain that construction. Lysine and threonine protect joint ligaments and muscle connective sheaths under heavy barbell loads. Histidine assists internal muscle carnosine synthesis, buffering metabolic acidity when training in warm Singapore gym facilities.
Athletes who combine Nutrex EAA with quality protein sources like PVL Iso Gold ensure round-the-clock nitrogen retention and accelerated recovery between rigorous training splits.
Hydration & Absorption Matrix: Calci-K, Coconut Water, and AstraGin
Singapore's year-round ambient temperature exceeding 30 degrees Celsius and relative humidity averaging 80% create severe fluid and mineral losses during physical activity. Standard water intake alone dilutes extracellular sodium concentrations, leading to hyponatremia, muscle weakness, and premature cramping.
The hydration component of Nutrex EAA tackles this challenge on three physiological levels:
1. Osmotic Muscle Cell Volumization with Taurine
Taurine functions as an organic osmolyte. At a full 1,000 mg dose, taurine draws water directly into muscle cells rather than allowing extracellular bloating. This cellular swelling increases cellular hydration, stabilizes cell membranes against oxidative mechanical stress, and enhances muscular force output during repetitive lifts.
2. Micro-Mineral Delivery via Calci-K and Coconut Water
Calci-K is a patented, highly soluble mineral complex combining calcium, potassium, and phosphorus in a bioavailable citrate-phosphate chelate. Unlike cheap calcium carbonate or potassium chloride that frequently upset digestion during heavy exertion, Calci-K absorbs rapidly through the gut lining. Combined with 100 mg of freeze-dried raw coconut water, it delivers trace minerals that replace what is expelled through sweat during intense cardio or lifting sessions.
3. Nutrient Uptake Optimization with AstraGin
AstraGin is a proprietary botanical extract composed of highly purified Astragalus membranaceus and Panax notoginseng. In published clinical studies, AstraGin upregulates specific intestinal transport proteins, including CAT1 (cationic amino acid transporter) and SGLT1 (sodium-glucose transport protein). By activating these nutrient gates, AstraGin enhances the cellular absorption rate of amino acids by up to 30%, ensuring that the active ingredients in your shaker reach working skeletal muscle tissue intact.
Nutrex EAA vs Alternative Amino Acids in Singapore
Choosing the right amino acid supplement depends on your training volume, dietary intake, and electrolyte requirements. While Nutrex EAA Hydration offers a balanced profile for general recovery, other dedicated formulas in our intra-workout supplements catalog cater to specific athletic demands.

If your goal prioritizes maximum clinical amino dose per serving, Mutant GEAAR from the trusted Mutant collection delivers 9.4 grams of total EAAs with 7 grams of BCAAs, backed by natural electrolyte sources. It represents an exceptional choice for heavy strength athletes in Singapore seeking higher amino density.

For trainees who demand advanced training endurance with added carbohydrates and full transparency, Ghost Intra from Ghost provides a premium hybrid formula incorporating aminos, hydration, and performance pumps.
