Leucine is an Essential Amino Acid; that means, unlike Non Essential Amino Acids, Leucine can\u2019t be produced in the body and must be ingested through the diet. This is one reason why supplementing with Leucine has become so popular, as obtaining higher Leucine quantities through the diet can be difficult.<\/p>\n<p>The research focus on <a href=\"https:\/\/www.bulk.com\/uk\/leucine.html\">Leucine<\/a> has been on its role in stimulating protein synthesis. According to Tipton et al (2009), \u201cLeucine is known to stimulate muscle protein synthesis and anabolism.\u201d Even in diets that contain sufficient protein, Leucine has been shown to chronically improve protein synthesis (Casperson et al, 2012). While the subjects for this study weren\u2019t typical sports nutrition consumers (the study looked at sarcopenia in older adults), it shows the additive benefit of Leucine.<\/p>\n<p>Interestingly, Tipton found that adding Leucine to Whey Protein didn\u2019t result in a greater anabolic response than Whey alone. This is likely to be due to the already high Leucine content of Whey Protein. Norton et al (2012) investigated four different protein sources, all with different Leucine concentration (Wheat, Soya, Egg and Whey) and found that \u201cLeucine content is a critical factor for evaluating the quantity and quality of proteins necessary\u2026for stimulation of maximal protein synthesis.\u201d<\/p>\n<p><strong>References<br \/>\n<\/strong>Casperson, S.L., Sheffield-Moore, M., Hewlings, S.J. &amp; Paddon-Jones, D.
