We’re making it easier than ever to find the products you need, whatever your goal.

That’s why we’ve changed L Leucine Essential Amino Acid to 100% L-Leucine Amino Acid - but don’t worry, we’ve definitely not changed the taste or the nutritionals, so it’s still your favourite…

L-leucine is an essential amino acid that can’t be made by your body, so must come from your diet — this can be time consuming and expensive, which is why we’ve created an easy-to-take supplement.

• Essential amino acid
• Naturally occurring in protein
• Easy to add to a smoothie or shake

Leucine is a BCAA (branched-chain amino acid) — these naturally occur in protein and help to build and repair new muscle.¹

Whether you’re a boxfit veteran, or a seasoned weight lifter, 100% L-Leucine Amino Acid is a super-simple support to your daily regime.

1. Protein contributes to the growth and maintenance of muscle mass.

Nutritionals based on Unflavoured version.

When to take 100% L-Leucine Amino Acid?

Just add 3g of leucine to water, juice, or your shake — twice a day for best results.  

What does 100% L-Leucine Amino Acid work well with?

Our leucine is fantastic to give you an amino acid boost when you need it most, but to make sure you’re getting your essential vitamins and minerals, add Alpha Men Multivitamin to your morning routine.
