EFECTIV® DiLeucine
DL185™, or L-Leucyl-L-Leucine Monohydrate, consists of two L-leucine molecules that are enzymatically bonded together. Leucine is well-established as a key regulator of muscle protein synthesis (MPS). It activates the mTOR pathway, which is critical for initiating protein translation and muscle growth[1]. However, research suggests that leucine alone may not be sufficient to maximally stimulate MPS[2].
This is where DL185™ comes in, harnessing the highly established anabolic power of leucine, resulting in meaningful performance benefits when combined with training.
Dileucine is a natural dietary component that can be found in all animal and plant protein sources. Animal protein contains higher amounts of dileucine compared to plant protein. However, protein alone cannot provide the clinically validated amounts of dileucine, as one would have to consume 159 grams of Whey Protein Concentrate or even 219 grams of pea protein to get the L-leucyl-L-leucine found in one 2g serving of DL185™[3].
