Glutamine and protein

[DionMacdonald]

Some places I've read that taking glutamine in a protein shake makes it less effective, other places that it boosts its effect, anyone know?!

 

[mr.cooper69]

It will be ineffective regardless of how you administer it.

 

[EasyEJL]

what effect are you talking about? glutamine's main purposes don't tend to have much to do with general protein's. And you realize that glutamine is in any protein powder anyhow right?

also, in case you don't understand that glutamic acid and l-glutamine are interchangeable

L-Glutamic Acid


L-glutamic acid is
made from a number of amino acids, including ornithine and arginine, states
Healthvitaminsguide. Glutamic acid is a non-essential amino acid, meaning it is
made by the body, a component of folic acid and a precursor to glutathione, a
powerful antioxidant. The acid also is referred to as glutamate, which is its
salt form. According to Chem-online, glutamic acid is involved in the metabolism
of sugar and fatty acids, and works as a neurotransmitter in the brain,
transporting potassium and detoxifying ammonia.

L-Glutamine


L-glutamine can be
synthesized, or made, from glutamic acid. Glutamine is the most abundant free
amino acid in the body, with most of it held in skeletal muscle cells, according
to an October 2009 study in "The Journal of Nutrition." It is metabolized in the
small intestine, where it is broken down and used as the main source of cellular
fuel, making it important in the regulation of your GI tract. The study also
states that glutamine is needed to fuel the cells of your immune
system, and at
times the kidney utilizes glutamine as well. It can be converted into glucose,
or sugar, when your body requires it, and it also helps to maintain the
acid/alkaline balance in the body, states
Healthvitaminsguide.

Synthesis


Glutamic acid and
glutamine are interconvertible, meaning that they can each make the other. Both
compounds have a similar base chain of molecules; glutamine has an amide group
while glutamic acid has a hydroxyl group attached to its chain. The study
published in "The Journal of Health" contains a diagram showing the addition of
an amide group to glutamic acid to form glutamine, and the cleaving of an amide
group from glutamine to make glutamic acid. Depending on available energy and
enzymes, the body can make use of either substance as function
demands.

Supplementation


In regards to
supplementation, L-glutamine and L-glutamic acid are typically used by athletes
and bodybuilders to promote muscle growth. L-glutamine also might be of use
post-surgery; according to Healthvitaminsguide, after surgery or extreme
illness, up to one-third of muscle stores of glutamine are released for nervous
system use. This release can lead to loss of muscle mass. L-glutamic acid is
considered excitatory, meaning tending to induce excitation, so talk to your
doctor before trying either L-glutamine or L-glutamic acid as a
supplement.

I mean for its effect on hgh production? I take 10g glutamine at night with 40g caisein , some people have told me to have my shake first then the glutamine a hour later

Again, glutamine supplementation is not needed for your typical bodybuilder. The body makes what it needs in vivo not to mention we get some through diet. A minimal spike in hgh will do nothing for composition. You're wasting time, effort, and money.

agreed with rhadam,nice info.
