To glutamine, or not to glutamine – that is the question. Well, it’s really not much of a question, considering the potential benefits of a high quality, high purity glutamine are far too numerous to ignore.

Despite the widely held belief that the scientific jury on glutamine is out, a fair amount of evidence exists to suggest that glutamine is beneficial to the human body in a variety of applications. Most of the problem, however, arises in the paltry servings that most companies throw into their formulations – effectively relegating glutamine to the “window dressing” category.

Not us. We are proud to feature glutamine, at effective servings, in our products. And we are even prouder to provide you a high quality source of pure glutamine that you can add to your already killer stack.

Science

Glutamine is one of the body’s most abundant amino acids, and is an amino acid known as, “conditionally essential.” This means that while the body is capable of producing it under normal physiological conditions, it may require additional dietary sources under certain conditions such as athletic training or stress. In these conditions, glutamine takes on a critical role in the metabolism of muscular protein, in the volumization of cells, and the reduction of cell catabolism (particularly in stressful or traumatic situations). Glutamine has additionally been demonstrated to be immunoprotective in stressful situations, meaning that supplementation with glutamine may help to maintain immune system function.

Great shoe, horrible lace design.
Size: 13, Color: White, Size: 13, Color: White
This shoes look great and the materials for the actual shoe feel great. They run a little big that doesn't bother me. Unfortunately, the lace design is horrible. I've now have 2 pairs of these shoes and both times the bottom lace has ripped out of the stitching. The first time was on the 2nd day I wore them, and the replacement pair to those it happened after I walked 20 feet. Both times I've tied a knot in the bottom lace so that I could get through the day. Ideally these laces should be connected together and not attached to the shoe (this is how both of my Skechers Slip-ins are designed). Because I like the rest of the shoe so much I'm buying elastic laces to replace the horrible original laces.

Good value for the money.
Size: 9.5 Wide, Color: Beige
Comfortable right out of the box. Great style and well made. The more you wear the softer they get but maintain their overall appearance.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
