Pure Essential Amino Acids Tablets for Muscle Growth And Repair

Fuel your muscles with 5g of all 9 essential amino acids in every serving. Our EAA tablets deliver research-backed ratios including 2,000mg of L-Leucine to maximise muscle protein synthesis and recovery.

Each bottle contains 300 tablets, 30 to 60 servings depending on whether you take 5 or 10 tablets a day. Each 5-tablet serving gives the same amino acid profile your muscles need for optimal growth and repair.

Why Choose Our EAAs Supplement Over Others

Unlike most amino acid supplements packed with fillers, ours are 100% filler-free. No magnesium stearate, silicon dioxide, or bulking agents—just pure fermented amino acids from natural corn glucose.

Our direct-compression grade amino acids are vegan-friendly with zero artificial sweeteners, flavours, or colours. Made in the UK under strict GMP and BRC standards, then third-party tested for purity and potency.

Best EAA Supplement for Serious Athletes

Whether you're training fasted, between meals, or need convenient on-the-go nutrition, these amino acid tablets provide complete essential amino acid coverage without the hassle of mixing powders.

Perfect for anyone following plant-based diets or looking for clean vegan amino acids that actually work. The research-aligned ratios ensure maximum uptake and utilisation.

EAAs During Cutting and Calorie Deficits

When calories are aggressively restricted — through fasting, low-calorie dieting, or appetite-suppressing approaches — the body breaks down both fat and muscle for fuel. Research shows that without adequate protein intake (1.6g per kg of bodyweight or higher), up to 40% of total weight lost can come from lean muscle mass.

Lean muscle drives resting metabolic rate, physical function, and long-term weight maintenance once restriction ends. Losing it makes regain almost inevitable.

The challenge across all these scenarios is the same — what's now widely called the protein gap: hitting 1.6g/kg/day from whole food becomes nearly impossible when satiety hits at 25–30g of protein per sitting. This is particularly pronounced for those using GLP-1 medications, where slowed gastric emptying compounds the issue.

EAAs close that gap. Each 5-tablet serving delivers 5g of essential amino acids and 2g of leucine — the dose research identifies as the threshold for triggering muscle protein synthesis (MPS). Fast-absorbing, near-zero calories, no digestive load.

Whether you're fasting, in a fat-loss phase, or supporting your nutrition during a structured nutrition programme, EAAs are an efficient way to protect lean mass without breaking your deficit.

Amino Acid Breakdown (Per 5g Serving)

Each serving of our Essential Amino Acids Tablets provides all 9 essential amino acids in precise, research-aligned ratios. These fermented EAAs work synergistically to support muscle repair, recovery, energy and training performance.

• L-Leucine – 2,000 mg
  The primary activator of the mTOR pathway, leucine is the key trigger for muscle protein synthesis and is essential for muscle repair and growth. Critical during any period of reduced calorie or protein intake, including appetite-suppressed states.
• L-Lysine (HCl) – 750 mg
  An essential amino acid your body cannot make, used in collagen formation and protein synthesis.
• L-Valine – 550 mg
  Helps reduce central fatigue, supports stamina and enhances overall training endurance.
• L-Isoleucine – 500 mg
  Improves glucose uptake and utilisation during exercise, helping stabilise energy levels and support endurance.
• L-Threonine – 415 mg
  Important for protein metabolism and normal connective tissue.
• L-Phenylalanine – 400 mg
  An essential amino acid used in normal protein synthesis.
• L-Methionine – 250 mg
  A sulphur-containing amino acid used in the synthesis of creatine and glutathione.
• L-Histidine (HCl) – 81.5 mg
  Precursor to carnosine, which buffers lactic acid during training.
• L-Tryptophan – 53.5 mg
  An essential amino acid and one of the nine your body cannot make.

This full spectrum delivers 5,000 mg (5g) of essential amino acids per serving, making this one of the most balanced and effective EAA supplements for supporting muscle, performance and recovery.
