  • L-Leucine is an essential amino acid‚ specifically classified as a "branched-chain amino acid" (BCAA). BCAAs‚ especially leucine‚ stimulate muscle protein synthesis and may be the major fuel involved in anabolic reactions. This makes them especially important for body builders and other athletes in sports that demand explosive strength.

    This one isn't for me

    L-Leucine Powder by Source Naturals is hard to mix with water. I had a lot of inflammation and frequent urination taking this. Works better if I take with whey powder and eat with a meal.


      I trust Source Naturals quality.


      Powder very hard to mix with water.

    The main BCAA for building muscle

    I take it daily to help build muscle. No bad side effects. Hard to mix in water, but the taste is neutral.


      Nice to take when there's a large time between meals. Could be beneficial on low carb diets where the body might try to take some of your protein sources away to use as glycogen. Will help build and mantain lean muscle. Recommended on the carb back loading program.


      Hard to mix in water! A blender would come in handy here, but it's not necessary.

    I would recommend this item to a friend.
