is glutamine better than protien???

[gangers]

is glutamine better than protien???

and how much glutamine should you take a day???

[CHAP]

They are not the same.

You need protein

And if you want to you can supplement with glutimine

[CHAP]

When I use glutamine I take 5g at a time
upon waking
bwo
pwo
bedtime

[jamyjamjr]

glutamine is for energy, protien is for mass bulding.. your comparing apples and oranges bro..

Nicly put!!!

[eatrainrest]

glutamine should only SUPPLEMENT, an already great diet, but then again an already great diet wouldnt need glutamine

[jamyjamjr]

well said eat

I remember reading somewhere that glutamine is not a good idea post work out because it competes with your whey in your shake for digestion. I have no science to back this. Anyone with any info on this?

Energy? Please elaborate...

Glutamine

--------------------------------------------------------------------------------

Glutamine (molecular weight: 146.15 g/mol) is one of the 20 amino acids encoded by the genetic code. Glutamine is a non-essential amino acid, meaning it can be produced by the body and is involved in a variety of metabolic processes. Glutamine has recently been re-classified as a conditionally essential amino acid. This means that while the body can make glutamine, under extreme physical stress the demand for glutamine exceeds the body's ability to synthesize it. During times of stress glutamine reserves are depleted and need to be replenished through supplementation. Glutamine is the most abundant amino acid in the body. Over 61% of skeletal muscle tissue is glutamine. L-glutamine is predominantly synthesized and stored in skeletal muscle. Glutamine is converted into the excitotoxin glutamate within neurons. Glutamine is then transported to the neuron and by the enzyme glutaminase, it is converted to glutamate--the potential excitotoxin. L-glutamine accounts for 30-35 percent of the amino acid nitrogen in the plasma. It contains two ammonia groups, one from its precursor, glutamate, and the other from free ammonia in the bloodstream. Glutamine is one of the three amino acids involved in glutathione synthesis. Glutathione, an important intracellular antioxidant and hepatic detoxifier, is comprised of glutamic acid, cysteine, and glycine.


Glutamine functions, uses, and health benefits

--------------------------------------------------------------------------------

Glutamine is involved in more metabolic processes than any other amino acid. Glutamine is converted to glucose when more glucose is required by the body as an energy source. Glutamine also plays a part in maintaining proper blood glucose levels and the right pH range. It serves as a source of fuel for cells lining the intestines. Without it, these cells waste away. It is also used by white blood cells and is important for immune function. Glutamine assists in maintaining the proper acid/alkaline balance in the body, and is the basis of the building blocks for the synthesis of RNA and DNA. Glutamine regulates the expression of certain
genes, including those that govern certain protective enzymes, and helps regulate the biosynthesis of DNA and RNA. Construction of deoxyribonucleic acid (DNA) is dependent upon adequate amounts of glutamine. Glutamine increases the body's ability to secrete human growth hormone (HGH). HGH assists in metabolizing body fat and helps to support new muscle tissue growth. Glutamine is important for removing excess ammonia. In the process of picking up ammonia, glutamine donates it when needed to make other amino acids, as well as sugar, and the antioxidant glutathione. The glutamic acid-glutamine interconversion is of central importance to the regulation of the levels of toxic ammonia in the body, and it is thus not surprising that when the concentrations of the amino acids of blood plasma are measured, glutamine is found to have the highest of all.


just some wholesome info...

[alpmaster]

Glutamine is most often supplemented to help halt the stored amino acid metabolism in a hypo-caloric state, which is what you posted. However, glutamine can be used (within the body) for 'mass' building and protein can be used for energy.

[jamyjamjr]

there's a gray perspective involved... they need more research imo..

[(1*)]

i never knew glutamine could be used for energy. in short, i have been told that it helps the nitrogen balance thus helping the body use fat for energy instead of muscle...

is this wrong. is it more that the glutamine is used for energy instead of the fat or muscle?

does glutamine have any bad effects when it comes to cutting if it can be used for energy?


coming on this forum reminds me that i don't know anything compared to what i think i know. lol

L-Glutamine is an amino acid therefore it is protein. When your body uses protein as an energy source it will search for L-Glutamine which is why many bodybuilders use it prior to training.

[MuscleScience]

Protein accounts for roughly 4% of total energy expenditure during exercise. Protein is not used as an energy source nearly as much as people think it is. Glutamate is essentially glutamine with an extra NH3 group.

Needless to say unless your in a very caloric deficient state (starving to death) glutamine is probably not going to be the first amino acid that is going to be in deficit.

I agree with everthing except the last part. I have read more than once (cant remember where) that when your body does go searching for an amino acid to use for energy L-Glutamine WILL be the first it searches for. If you have something stating otherwise please post it so I can adjust my thinking.

possibly here

if you can, order some bulk glutamine (around 15-20$ for 500g) and take around 5-10g before cardio, this will give your body a large amount of glutamine to use to replenish it's amino acid pool. The reason this is important is because when your body enters a catabolic state it breaks down muscle tissue into it's constitute amino acids and transports those to your liver where they are broken down into alanine and converted into glycogen via gluconeogenesis. But this can be avoided by providing your body with either protein for it to break down into amino acids or the aminos themselves. Btw, glutamine makes up about 60% of the aminos in muscle tissue and therefore is the most used amino during gluconeogenesis, that's why i recommend it.

Yeah L-glutamine is used as a fuel source when necessary. Its just that it takes a long time and many enzymatic process compared to glycolysis for example to convert any amino acid to a usable form of energy. The brain for example can use alpha-ketoglutarate as a fuel source along with enterocytes. At any one point in time your body is using all possible fuel sources to produce energy including amino acids. Its just that amino acids under normal conditions are not in proportion to other fuel sources used nearly as much, especially during exercise when even under high exercise intensities fats can not be processed in great amounts to keep up with energy demands.

well then.. that answers that.. lol... good info guys..

I have heard or read this also....but can't find much info on it, however i did see some good stuff on adding to your PWO shake-----> It helps with insulin !

if i remember correctly there was an article in mens health a year or two ago that talked very bad about glutamine. this started a huge debate among lifters in my area.
funny thing is that another article in that magazine (i can't remember if it was the same issue or another issue on the same desk) had an article that listed glutamine as being a very important supplement.

screw fitness/health mags... i dont trust a word in them...

do people still read magazines eh?
