Thanks a lot for pointing out.
( did not read description myself before. , It is right there)
I'm vegan. Will give it a shot. What can go wrong. hehe

So all, I'm mostly a runner doing minor strength building for 10k races. Can I ask, what's the best way to use this stuff and does it increase strength? Thanks in advance.

Glutamine supplements are worthless for bodybuilding. Every study that has ever looked at this came to the same result. Enjoy wasting your money.

is it worth getting it if someone is doing P90X? I am going to start it next weekend...

for all those asking whether it's redundant or a waste, a good part of taking supplements and nutrition in general is timing. this type of glutamine will absorb into your bloodstream a lot faster than what's packed into your protein shakes. multiple products may "overlap" in terms of their contents, but when it comes down to it, educate yourself in terms of absorption and digesting rates of whatever supplement you're taking and you will be fine.

and ignore the "haters" out there ;-)



edit: spelling.

Not a problem, it's kind of hidden

Glutamine = placebo. It's almost useless in athletic performance/recovery.

"Glutamine "works", but not for building muscle like creatine. Think of glutamine as a muscle preservative. The time to be taking glutamine isn't when you're trying to build muscle, but when you are trying to keep what you have.

For instance, many people don't like to eat a few hours before bed, especially nothing heavy like protein. This would be a good time to take glutamine, right before bed. When you awake in a fasted state, this would be a good time to take glutamine. Any time you are dieting or fasting, especially low protein diets, glutamine is a good thing.

Another good time for glutamine is at the end of a cycle. This is for two reasons, you'll be able to start eating less protein to keep from getting fat while still preserving your muscle, and second because glutamine inhiibits cortisol, and the decreased ratio of testosterone to cortisol is believed to be the cause of lost muscle mass at the end of a cycle.

The time not to be taking glutamine is when you are consuming protein and trying to build muscle. Any large dose of one amino acid has the side effect of inhibiting the absorption of all others, so don't take glutamine at the same time you consume protein, or better yet until the protien is fully digested."

Damn, just bought this for $33 the other day! Oh well, better buy some more!

Here's what I found with a quick search, sounds like the benefit is more theoretical than real:

Dosing and efficacy of glutamine supplementation in human exercise and sport training.

Abstract

Some athletes can have high intakes of l-glutamine because of their high energy and protein intakes and also because they consume protein supplements, protein hydrolysates, and free amino acids. Prolonged exercise and periods of heavy training are associated with a decrease in the plasma glutamine concentration and this has been suggested to be a potential cause of the exercise-induced immune impairment and increased susceptibility to infection in athletes. However, several recent glutamine feeding intervention studies indicate that although the plasma glutamine concentration can be kept constant during and after prolonged strenuous exercise, the glutamine supplementation does not prevent the postexercise changes in several aspects of immune function. Although glutamine is essential for lymphocyte proliferation, the plasma glutamine concentration does not fall sufficiently low after exercise to compromise the rate of proliferation. Acute intakes of glutamine of approximately 20-30 g seem to be without ill effect in healthy adult humans and no harm was reported in 1 study in which athletes consumed 28 g glutamine every day for 14 d. Doses of up to 0.65 g/kg body mass of glutamine (in solution or as a suspension) have been reported to be tolerated by patients and did not result in abnormal plasma ammonia levels. However, the suggested reasons for taking glutamine supplements (support for immune system, increased glycogen synthesis, anticatabolic effect) have received little support from well-controlled scientific studies in healthy, well-nourished humans.

Quote from thatguy3579 : The science literature has mostly debunked the need and effectiveness of L-Glutamine supplementation for the non-anemic. The average person will not bulk up faster or recover more quickly with this.

Yep..Glut is useless..
