What is Leucine and why is it so special?

Leucine is a Branch Chain Amino Acid (one of the 3, along with Isoleucine and Valine). Leucine is considered the amino acid with the greatest muscle building benefits - it has been scientifically proven to boost protein synthesis, and stimulate muscle growth.

Leucine stimulates muscle growth by activating mTOR - the "mammalian target of rapamycin". What's mTOR? It's essentially an internal sensor for insulin, growth factors (such as IGF-1 and IGF-2), amino acids, cellular nutrients, oxygen, and energy levels. In other words, it senses what's happening in your body and tells your muscles when they can repair and grow! By taking Leucine, you're triggering mTOR to tell your muscles to use available dietary protein and start growing. It makes your body utilise available protein more effectively for muscle growth, and is a perfect addition to any post workout protein shake to trigger greater gains from your workout.

How much should I take?

We recommend 3 grams in your post workout protein shake. You can also include 3 grams in your intra-workout shake if you're dieting (and risk going into catabolism) or bulking and looking for maximum muscle growth.

At Bodybuilding Warehouse we pride ourselves on quality. Our Pure Leucien has been produced in-house in our own custom built factory, using ingredients from approved, audited suppliers who meet our strict quality assurance standards, and work within our principles.

I add Leucine to my pre and post workout. On non training days I mix in with pure orange juice about an hour before a meal in the morning and again early evening. Brilliant product at a brilliant price.
Personally I don't like the taste when mixed with water that's why i put it in my pre & post workouts or Pure Orange juice.
Will defenetely be ordering more.

I prefer to add extra leucine to my shakes and I have found this version mixes in perfectly and much easier to drink, you don't get that dry hit of leucine powder at the roof of your mouth. All in all I would buy again and recommend.


Leucine is a must in your supplement stack
