4.0 out of 5 stars Usuall great but 1/3 of the capsules stuck together in middle of the bottle

8. · August 4, 2024

We have this on a subscription so it's delivered automatically but in this last order 1/3 of the capsules were stuck together in the middle of the bottle making them unusable, however, usually, these are great.Several capsules were broken and the powder was all over the other capsules and the inside of the bottle. I held the bottle up which you can see in the photo with the capsules stuck in the neck of the bottle in a clump. This was the first time we received a bottle like this so I sent a message to the company to let them know. We haven't had any problems before and we are really happy with Optimum Nutrition's L-Glutamine. We have found the product to be consistently good quality, good with muscle soreness. Helps with digestion and gut health so far.

5.0 out of 5 stars No More Soreness!

F. · November 7, 2014

I've used Glutamine off and on for years, mainly off, because it is really pretty expensive. However, I decided to pick up a small bottle from a local supplement store to give another try. Here is my dosing and experience:My stack is as follows:4 Arginine (2 Grams) and 1.5 scoops N.O. Explode (Non-Caffeinated) 1-1.25 hours pre workout20 grams glutamine with 3 scoops ON Amino Energy 30 minutes pre workout.This is a recently discovered God send of a stack. I increase in weight every week at a minimum of 5%, and up to 20% (The larger increase comes from the deadlift. Started at 180 and within 2 weeks was up to 240. Its been awhile since I've done them, so i needed my back to get used to it). This week alone my Deadlift increased 40 pounds (My legs are strong enough, my back isn't used to moving that kind of weight just yet). That's a 15%+ increase! Its the same for all my lifts. It sounds great, right? Well, here's the problem. When your body isn't used to constantly increasing weight, you tend to get pretty sore. That's where the magic of Glutamine comes in, well, one of the two pieces of magik anyway. The most notable is that you will either not be sore at all, or have just a trace of soreness. This allows you to lift heavier, which means increased strength and increased muscle mass. Epic.The second great part about glutamine is that if taken at 20-25 grams (Some people apparently get an upset stomach when they take this much. I've never had a problem), you will notice increased strength, compared to if you don't use it. Hooray! And, seeing how I am a vegetarian, supplementing is important since I don't eat meat. Therefore, my Glutmaine levels are lower than most people.Should you buy Glutamine? Well, I suppose that depends on your goals. Are you lifting to train? Or are you just lifting for maintenance? If for the latter, I would honestly say skip it, and maybe try Taurine and Beta-Alanine instead. But if you are training (And by training, I mean pouring every ounce of energy into every single set and pushing yourself as hard as you can, and then some), then I would say you would likely see a benefit. I know I do. And the way I see it, if you aren't ever getting sore, you're doing it wrong. (Coming from 10 years of fitness experience, and former personal trainer certification)

5.0 out of 5 stars Use it everyday!

The media could not be loaded. Big fan of glutamine because of its benefits, easy to swallow and great for protein. I use it almost every day

You don't need to take it everyday. Only take it after intense workout or when you are sore. It will help in healing and reparing your muscles. You can take it with protein powder + creatine and mixing it. Taking the glutamine alone can taste bit bland and after taste would be even bitter. Mix it with something while drinking.
