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
Nutritional information may vary depending on flavour.
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.
We advise that all servings are measured using an accurate set of scales. While we make every attempt to provide an accurate equivalent measure using our Myprotein scoops, these are only approximate and are not a substitute for using a standardised measuring device. Do not exceed the stated recommended daily dose. This product is a food supplement and therefore should not be used as a substitute for a varied diet and a healthy lifestyle.

Good product but rarely in stock
I think this is an excellent product but it hasn’t been in stock for at least 4 weeks. Hard to rely on steady use of a product if you can rely on a steady supply.

Not good bad batch
Received 500g of leucine. When opened I noticed a very foul smell. Strong ammonia , and strong smell of sweaty feet. Just finished an earlier pouch which was ok. Been using this product for yrs never a problem. Obviously some sort of contamination. Goes Well With:Bin

Poor packaging!
The product is ok, however, the pouche it comes in does not reseal, so I have had to empty the contents into my own container - to maintain freshness. The pouches they use have always been difficult to reseal, in my experience. Annoying! Goes Well With:Another container.
