What Dorian Yates say about Ultimate Glutamine:
Dorian Yates Ultimate Glutamine Formula is the best formula available because it contains a 4:1 ratio of N-acetyl glutamine to glutamine peptides.
It incorporates the latest science and practical experience in building a lean, muscular body!
You want the best results possible in the shortest period of time. Youre looking for bigger muscles, enhanced strength, improved endurance, faster recovery, increased absorption and synthesis of protein to support quicker muscle building.
Peptide bonded amino acids, such as glutamine, can be absorbed up to 20 times more efficiently than amino acids in their free form, such as L-glutamine.
This is because the absorption mechanism for peptide-bound amino acids is much less competitive than that for free amino acids in the presence of other proteins and amino acids. This is also why it is wasteful to take L-glutamine with food or protein shakes.
N-acetyl glutamine converts to the free amino acid ONCE ABSORBED, but unique to this form, around 10% of the amount absorbed gets retained in the short term within the intestinal lumen (Arnaud et al, 2004), where it plays a key role in maintaining gut integrity, so improving the absorption of protein and other nutrients.
This also contributes to a more sustained delivery of glutamine over the L-glutamine form with the corresponding increase in effectiveness. The N-acetyl form is also more stable in water and overcomes the intolerance problems sometimes evident with L-glutamine. Glutamine is the single most abundant free amino acid in the body and the greatest pool of it tends to be found in muscle. As one of the most important amino acids in the body, it plays a direct role in building lean muscle tissue (Kreider, 1999).
By making sure your body has sufficient pools of glutamine available, particularly after exercise and before sleep, you are helping your body to build skeletal muscle. Intense training is known to compromise the effectiveness of the immune system. It seems that the well-known and often frustrating association between intense, especially prolonged, exercise and immune suppression may be linked with a depleted glutamine pool in the body.
A number of studies have shown clearly that intense training (or worse, overtraining) leads to lower blood levels of glutamine concentrations (Keast et al, 1995; Castell & Newsholme, 1997).
There is also some evidence to suggest that glutamine supplementation might enhance natural growth hormone levels (Welbourne, 1995). Growth hormone contributes to the muscle building and repair processes in the body and is strongly anti-aging, energy and immune system supportive.
