Essential Amino Acids (EAAs) Supplementation
You’ve probably heard the term “amino acids” thrown around the gym or online, but what makes Essential Amino Acids so... essential?
Essential Amino Acids (EAAs) are the nine amino acids your body can’t produce on its own — meaning they must come from your diet or supplementation. They play a critical role in muscle growth, repair, and recovery, and are especially important around training when your muscles are under the most stress.
Whether your goal is to build muscle, support recovery, enhance performance, or maintain general wellbeing, EAAs are the foundation of any smart supplement routine.

Discover the Best EAAs for Training and Recovery
At Bulk Nutrients, we believe supplements should be clean, effective, and purpose-built. That’s why our amino acid range is made using 100% pharmaceutical grade ingredients — with no fillers, artificial colours, or unnecessary additives.
To meet your unique training needs, we offer two powerful EAA products — each designed to deliver maximum support before, during, and after your workouts.
Essential Amino Acids (EAAs) Powder
If you're looking for a pure, unflavoured EAA source, this product delivers. Our Essential Amino Acids Powder includes all nine EAAs in their free-form state: Leucine, Isoleucine, Valine, Histidine, Lysine, Methionine, Phenylalanine, Threonine, and Tryptophan. It’s the ideal choice for:
- Fasted or low-protein training
- Enhancing protein synthesis
- Minimising muscle breakdown
- Supporting lean muscle development
With no flavours or sweeteners, it’s easy to stack into your shake, pre-workout, or daily hydration mix.

Intra Workout
Formulated for peak performance during your training session, Bulk Nutrients' Intra Workout is a complete, flavoured blend of Essential Amino Acids plus performance support ingredients. Each serve delivers a powerful 21g of amino acids — covering all nine essentials — alongside key nutrients to support:
- Hydration and endurance
- Intra-session recovery
- Mental focus and reduced fatigue
It’s the ideal companion for longer or more intense sessions, keeping your body fuelled and muscles protected while you train.

Why Combine These Two?
Together, these two products offer versatility and targeted support:
- Use Intra Workout during training for hydration, amino delivery, and performance.
- Use Essential Amino Acids Powder pre- or post-workout, or on non-training days, to keep your amino intake consistent and muscle recovery supported.
Both are designed with precision dosing, maximum purity, and no unnecessary ingredients — giving your body exactly what it needs, when it needs it.
