5.0 out of 5 stars A Great Product, August 22, 2010
Amazon Verified Purchase(What's this?)
This review is from: Source Naturals L-Glutamine Powder, 16 Ounce (Health and Beauty)
Considering that this product is only so much money it is very well worth the price but let me tell you about what it does. I'm a bodybuilder only a teen though. Glutamine in my experience helps recover so much faster. I don't know how to explain in how it does that but I feel much more energized. Not so much like caffeine energy but it even helps me foucslike doing simple things like driving, and become alert as it is a Neuro-transmitter.

Another important thing to note is that if you live in the U.S or in the western side of the world then this may benefit you highly since most foods on the western side are acidic. Glutamine ups the alkaline reserves in your body so you don't metabolize your muscles, and have and acidic ph level in your system.

In the end this is great product. I've felt better by using it, but I don't know how much muscle growth I really got helped from it since muscle growth is great there is no real way to shrink my muscles and re-test.

5.0 out of 5 stars Glutamine for Irritable bowel and ulcerative colitis, April 21, 2011
Amazon Verified Purchase(What's this?)
This review is from: Source Naturals L-Glutamine Powder, 16 Ounce (Health and Beauty)
All my online research about IBS and other forms of colitis, recommend l-Glutamine for healing the intestines. It helps restore the lining. After my original diagnosis, I started using this brand of L-glutamine daily, and it helped immediately.

It also cuts down on sugar cravings. You can't beat that!

5.0 out of 5 stars Noticed an immediate weight gain, September 20, 2009
By 
J. M. Gates (White Plains, NY United States) - See all my reviews
(REAL NAME)   
Amazon Verified Purchase(What's this?)
This review is from: Source Naturals L-Glutamine Powder, 16 Ounce (Health and Beauty)
I lift weights five days a week and drink tons of whey protein and yet I've had problems gaining significant amounts of muscle mass. This is probably due to lack of sleep and proper nutrition necessary for hypertrophy. The second I started taking this product I started gaining. In just two weeks I packed on eight pounds! None of it fat!

On the down side it added a funny chemical taste to my shake. The taste went away when I doubled the amount of milk though. This is what I take:

2 servings ( 60 grams) whey protein

2 servings (16 fl. oz.) skim milk

3 grams l-glutamine

1 gram Phosphatidyl serine

1/2 gram GABA

(1/4 teaspoon is approx. one gram)

That's one shake and I take it four times a day. Once in the morning, immediately following a workout, one hour after post-workout, and the last shake in the evening. I also take one gram of beta-alanine and one gram of creatine an hour before exercise. I take a 1200 mg omega 3 capsule (x2 a day), 2000 IU vitamin d, and one vitamin b complex pill.

If anyone decides to try my recipe remember to drink plenty of water afterwards. All that protein will give you heartburn.
