Because it is an essential amino acid, humans cannot synthesize it. This means it must be obtained through diet or supplements. Some foods containing L-leucine include eggs, fish, chicken, lentils, almonds and cashews.As an essential amino acid, leucine is not synthesized in animals, hence it must be ingested, usually as a component of proteins. It is synthesized in plants and microorganisms via several steps starting fromAs a dietary supplement, leucine has been found to slow the degradation of muscle tissue by increasing the synthesis of muscle proteins.Leucine is utilized in the liver, adipose tissue, and muscle tissue. In adipose and muscle tissue, leucine is used in the formation of , and the combined usage of leucine in these two tissues is seven times greater than its use in the liver.ItemSpecificationResultAssay98.5 - 100.5% l-leucine98.5 - 100.5% l-leucineAppearanceWhite crystals PowderconformsOdorCharacteristicconformsTasteCharacteristicconformsParticle SizeNLT 100% Through 80 meshconformsLoss on Drying<2.0%0.47%Heavy metalsTotal Heavy metals≤10ppmconformsArsenic≤3ppmconformsLead≤3ppmconformsMicrobiological TestsTotal Plate Count≤1000cfu/gconformsTotal Yeast & Mold≤100cfu/gconformsE.ColiNegativeNegativeSalmonellaNegativeNegative
