About Amino Acid Blends

There’s little chance that you’ve not heard about amino acids before. Over the last few decades, our understanding of these nutrients has been increasing exponentially, due to the fact that scientific inquiries have been made more and more frequently, mostly in the form of clinical trials. The first amino acid was discovered way back in 1806 in asparagus, and was named asparagine, for obvious reasons. Amino acids are generally classified with regards to their essentiality to the human body. For example, tryptophan—an essential amino acid—is named as such because the human body lacks the enzymes necessary to synthesize it, and, because it plays essential roles in the human body. One of these roles is the synthesis of the neurotransmitter serotonin, which is located in the gut and the brain. Therefore, an essential amino acid is one that we cannot synthesize, we need, and therefore we must consume through food or supplements in order to stay healthy.


Another essential amino acid is phenylalanine, which we need for the structure of skeletal muscle tissue proteins, and also for the synthesis of the catecholamines, which are noradrenaline, adrenaline and dopamine. In fact, the muscle uses phenylalanine solely for the purpose of creating structural proteins, and for this reason scientists use it as a marker when studying rates of muscle protein synthesis, i.e., they measure how much phenylalanine is released from muscle in response to a supplement. The rest is built into new muscle protein.  


There are also a host of non-essential amino acids and conditionally-essential amino acids, the former of which we can manufacture adequate amounts of, and the latter of which under certain physiological circumstances, our synthetic rates may not be adequate. However, some of the non-essential amino acids can be helpful during exercise to elicit a specific physiological response. One example of this is Citrulline, which often comes in the form of Citrulline malate. This amino acid has been shown to elevate blood arginine levels better than arginine itself, where it can then be used for the synthesis of nitric oxide (NO). NO is a gas—that's right, we manufacture gas inside our own bodies!—that signals the smooth muscles of the blood vessels to relax. This causes dilation of the blood vessels and enhances blood flow to the peripheries, such as skeletal muscle tissue. And with blood, comes nutrients, such as oxygen and glucose, which enhance performance and recovery between sets. This may also boost the "muscle-pump" effect that many gym-goers enjoy during and after exercise.


There are over twenty different amino acids—nine of which are essential—that all play different roles in the human body. Take your time perusing our amino acids section to find out which product meets your needs.
