BCAA Amino Acids Drink Mix – Muscle & Endurance

BCAAs are the amino acids your muscles burn during training. Leucine, isoleucine and valine — the three branched-chain amino acids that drive muscle protein synthesis, delay fatigue, and reduce muscle breakdown during intense or prolonged exercise. Most BCAA supplements are animal-derived. This one is plant-based, vegan, halal approved, and includes citrulline malate for pump and L-citrulline for endurance on top of the amino acid base.

Why BCAAs Matter During Training (Not Just After)

Protein consumed before and after training supports muscle protein synthesis in the recovery window. BCAAs target a different problem: muscle catabolism during training itself. During sustained high-intensity exercise, your body can oxidise BCAAs for fuel — breaking down muscle tissue to do so. Supplementing BCAAs intra-session maintains elevated amino acid availability, reducing muscle breakdown and supporting endurance.

The leucine in BCAAs also directly activates the mTOR pathway — the primary signalling cascade for muscle protein synthesis — which is why BCAA supplementation is effective even in a fasted training state. Research published in the Journal of Nutrition confirms leucine-enriched BCAA supplementation significantly stimulates muscle protein synthesis, supporting the use case for intra-workout amino acid supplementation.

Why Competitors Fall Short

MyProtein Vegan BCAA — lower dose, not halal. MyProtein's vegan BCAA is a clean product but provides a lower amino acid dose per serving and carries no halal certification. This BCAA is halal approved and delivers a full 5.6g amino acid dose alongside citrulline malate.

Bulk Vegan BCAA — not halal. Bulk's vegan BCAA is competitively priced and a reasonable product, but carries no halal certification and doesn't include the citrulline malate and L-citrulline endurance/pump stack that this formula adds.

Most BCAA supplements — animal-derived. The majority of BCAA powders use fermentation from animal-derived sources, or duck feathers (a common industrial source). Vegan BCAAs require plant fermentation — a more expensive but fully plant-derived process. This formula is plant-fermented, vegan-certified, and halal approved.

What's in Every Serving

• BCAA 2:1:1 (leucine:isoleucine:valine) — 5.6g · plant-fermented · the clinically validated 2:1:1 ratio maximises leucine-driven mTOR activation while maintaining the valine:isoleucine balance for fatigue resistance
• Citrulline malate · supports nitric oxide production · increases blood flow and oxygen delivery to muscles during training · reduces time to fatigue
• L-citrulline · endurance support · reduces ammonia accumulation in muscle during exercise
• Vitamin B6 · contributes to normal protein and glycogen metabolism (EU authorised) · supports amino acid processing
• Vitamin C · contributes to protection of cells from oxidative stress (EU authorised) · antioxidant support during high-intensity exercise

Every serving is:  ✓ Halal approved  ·  ✓ Vegan  ·  ✓ Plant-fermented BCAAs  ·  ✓ Gluten-free  ·  ✓ Dairy-free  ·  ✓ UK GMP made

How to Take It

Mix 1 serving with 400–500ml of cold water and sip throughout your workout. Intra-workout use is the primary application — maintaining amino acid availability and supporting endurance during the session. Can also be used pre-workout as a stimulant-free amino acid primer.

Use alongside Intra-Workout for sessions requiring both amino acid support and creatine/energy during training. Post-session, Post-Workout Chocolate provides the carbohydrate glycogen replenishment and multi-source protein recovery formula. Stack Creatine Monohydrate daily for peak strength output across sessions.

Is This You?

• You're vegan and need a plant-fermented BCAA — most BCAAs are animal-derived (including duck feather sources)
• You need a halal certified amino acid supplement for intra-workout use
• You train fasted and want intra-session amino acid support without carbohydrates or protein
• You want BCAAs plus citrulline malate for pump and endurance in one product, not separate supplements
• You train hard and experience muscular fatigue mid-session that affects your final sets
