Here is information on the use of Glutamine for Inflammatory Bowel Disease (ulcerative colitis and Crohn’s disease) and for HIV/AIDS. These excerpts are from the University of Maryland Medical Center’s Complementary Medicine web resource, which provides an extensive and generally up-to-date database on nutritional supplements and their applications.

NYBC stocks:

 Glutamine as a bulk powder (1 kilogram)

and

Glutamine capsules 500mg/100.

Note: Glutamine is one of the main components of Juven, a patented blend that also includes L-arginine and HMB. Unfortunately “patented” = much more expensive. It’s a lot cheaper to purchase Glutamine in bulk than to buy it in the form of Juven!

Glutamine is the most abundant amino acid (building block of protein) in the bloodstream. It is considered a “conditionally essential amino acid” because it can be manufactured in the body, but under extreme physical stress the demand for glutamine exceeds the body’s ability to synthesize it.

Inflammatory Bowel Disease (IBD)
Glutamine helps to protect the lining of the gastrointestinal tract known as the mucosa. Because of this, some experts speculate that glutamine deficiency may play a role in the development of IBD, namely ulcerative colitis and Crohn’s disease. These conditions are characterized by damage to the mucosal lining of the small and/or large intestines, which leads to inflammation, infection, and ulcerations (holes). In fact, some preliminary research suggests that glutamine may be a valuable supplement during treatment of IBD because it promotes healing of the cells in the intestines and improves diarrhea associated with IBD. Not all studies have found this positive benefit, however. For this reason, more research is needed before conclusions can be drawn. In the meantime, follow the advice of your healthcare provider when deciding whether to use glutamine for IBD.

HIV/AIDS
Individuals with advanced stages of human immunodeficiency virus (HIV) often experience severe weight loss (particularly loss of muscle mass). A few studies of individuals with HIV have demonstrated that glutamine supplementation, along with other important nutrients including vitamins C and E, beta-carotene, selenium, and N-acetylcysteine, may reduce the severe weight loss associated with this condition.

Here’s a good overview of some issues related to maintenance of optimum weight for people with HIV. This is an excerpt from the University Of Maryland Medical Center’s Complementary/Alternative Medicine website.

Some of the key supplements mentioned below are:

Glutamine

Arginine

—-

Another study found that a combination of glutamine (7 g per day), arginine (7 g), and an amino acid derivative called hydroxymethylbutyrate or HMB (1.5 g) helped people gain lean body weight during 8 weeks of treatment compared to placebo. High doses of arginine however, may be linked to an increase in herpes viral outbreaks. To find the right dose that offers benefits without dangerous side effects, consult with a trained nutritionally oriented physician.

This post runs a little long, but we think it’s worthwhile to put up the FAQ about nutritional supplements recently posted by the New York Buyers’ Club. It answers a lot of (sometimes anxious) queries about supplements, and also gives a quick rundown on some of the top uses of supplements among the NYBC membership.

What are supplements?
A nutritional or dietary supplement (or just plain supplement), as defined by the Dietary Supplement Health and Education Act (DSHEA) of 1994, is “a product (other than tobacco) that is intended to supplement the diet and that contains one or more of the following: vitamins, minerals, herbs or other botanicals, amino acids, or any combination of the above ingredients,” and can be taken in tablet, capsule, powder, or liquid form.
NYBC specializes in supplements for those with HIV, hepatitis C, and other chronic conditions. Our Supplement Fact Sheets contain information on more than 100 supplements commonly used by our Members. Our nonprofit purchasing co-op stocks these supplements on a regular basis, and can also special-order many other supplements on request.
Why take supplements?
There is a great deal of research showing that supplements can help people manage serious chronic conditions such as HIV and hepatitis. Supplements can also be useful in addressing many common health issues, such as high cholesterol, diabetes, depression, arthritis pain, gastrointestinal disorders, etc. (see our short list of specifics below). Some supplements are derived from ancient traditions of use (for example, the botanicals of India’s Ayurvedic tradition), while other items (such as vitamins or amino acids) have been isolated and used as supplements much more recently. The scientific study of supplements has blossomed in recent decades, so we now have better evidence about many of them—even traditional botanicals—than we ever did in the past.
Are supplements considered “medicine”?
While supplements may have medicinal properties, they are not regulated in the same way that prescription drugs are, and are therefore accompanied by the disclaimer: “These statements have not been evaluated by the Food & Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”
The fact that supplements are not regulated in the same way that prescription drugs are naturally gives rise to concerns about purity, efficacy, and safety – so it’s good to have a knowledgeable ally like NYBC on your side! Collectively, we have many years of experience in using supplements, in researching information on them, and in evaluating suppliers to obtain the best quality product.
Are supplements “safe”?
Under current US regulations, supplements are assumed to be safe on the basis of their history of use, or because they are found in the food supply (like the microorganisms in yogurt or the vitamins and minerals in foods). The US Food and Drug Administration is responsible for removing supplements from the market if it finds evidence that they are unsafe, but it’s worth noting that this happens quite rarely. (The removal from the market of ephedra [aka the Chinese herb Ma huang], used at high dosage as a diet pill, is practically the only significant example since 1994). However, while supplements may be “assumed to be safe,” everyone who takes them needs to pay attention to the recommended dosage and any cautions or warnings. If you exceed the recommended dosage of certain supplements, there may be side effects, sometimes serious. Furthermore, a supplement may have negative interactions with other medications you are taking, or a particular supplement may not be a wise choice for you due to other health concerns. That’s why it’s always important to discuss your supplement use with your doctor.

Here are just a few examples of potentially dangerous supplement-medication interactions (from the National Center for Complementary and Alternative Medicine’s website) - further proof that consulting your physician about supplement use is crucial:

• St. John’s Wort can increase the effects of prescription drugs used to treat depression. It also dangerously interferes with drugs used for HIV, cancer, birth control, and rejection of organ transplants

• Ginseng can increase the stimulant effects of caffeine (as in coffee, tea, and cola). It can also lower blood sugar levels, creating the possibility of problems when used with diabetes drugs

• Ginkgo, taken with anticoagulant or antiplatelet drugs, may increase the risk of bleeding. Ginkgo may also interact with certain psychiatric drugs and with certain drugs that affect blood sugar levels

Of course, doing your own “homework” is also encouraged. Be sure to bring any notes or printouts from your research to share with your healthcare provider. That way, you’ll both be literally on the same page.
Identity, Purity and Potency
Safety is also a matter of product quality. Is the product what it claims to be on the label (that is, is it really fish oil)? This is the product Identity. Does the product contain any unwanted contaminants like heavy metals, insect parts, rodent droppings? All foods and medicinal products face these issues of Purity. And finally, does it have as much of the claimed amount of a substance? For example, if it says 100 mg of niacin, does it have that amount? This is the product’s Potency. These issues are of ongoing concern. NYBC has done everything possible to assure that products meet these standards. Websites such as www.consumerlab.com can help. Also indications of quality such as USP or other labels further add assurance. The good news is that the vast majority of products tested by consumerlab, for example, pass their tests. Still, NYBC believes an appropriately funded agency of the FDA could do more rigorous, routine and comprehensive testing.
What is CAM?
CAM is an acronym for complementary and alternative medicine. The use of supplements is considered CAM. Some prefer the term integrative medicine.
The National Center for Complementary and Alternative Medicine (NCCAM), a division of the US National Institutes of Health, defines CAM as “a group of diverse medical and health care systems, practices and products that are not presently considered to be part of conventional medicine.” NCCAM, like the US Office of Dietary Supplements, came into being after passage of DSHEA, and marks the federal government’s decision to commit funding to research and education about CAM. Over a billion dollars in your tax dollars have been spent by these agencies since their start.

Using Supplements
What supplements can I use to improve my immune system?
Agents such as a potent multivitamin, NAC (N-acetyl cysteine), alpha lipoic acid and whey can all help offset oxidative stress and nutrient losses caused by HIV as well as the free radical generation and inflammation-related damage that some antiretroviral drugs cause.
For those with HIV, supplementation can be a valuable assist in restoring the body’s immune system, as evidenced by many studies, such as Dr. Jon Kaiser’s HIV Micronutrient Study, which showed a significant increase (26%) in the CD4 counts of the subjects who maintained a supplement regimen in addition to their regular medications. FYI: NYBC offers a “MAC Pack” (Micronutrient - Antioxidant Combination Pack), a product very similar to the one used in the study.
What supplements can be used to improve gut function?
Acidophilus or bifidus, glutamine, whey proteins, Saccharomyces boulardii (Florastor) and a good multi can all be important to offset gastrointestinal problems, whether HIV-related or of other origin.
What supplements can I use to manage my blood fats (cholesterol and triglyceride levels)?
“Bad cholesterol” (LDL) and triglycerides can be reduced with agents such as carnitine, pantethine, and fish oils. Niacin may be an excellent option which can also help increase HDL (“good cholesterol”). For heart health in general, aside from diet and exercise, CoEnzyme Q10 may also be of help (may also be useful in countering statin-related side effects).
What supplements are used to improve mental function and/or mood?
Acetylcarnitine, 5-HTP, tyrosine, ginkgo biloba, fish oils, SAM-e, DHEA, theanine, or St. John’s Wort may help mental function and alleviate depression, though each of these must be taken with some care (and not all together!)
See also: a full dossier on Memory Loss and Other Brain Problems from our Health+HIV section of Recommended Reading on the website www.newyorkbuyersclub.org; also recommended is the NYBC info sheet on Depression and supplements on this blog, under “Depression.”
What supplements can I use to combat fatigue?
Various conditions can cause fatigue, but in general, B12 (methylcobalamin) and Eleuthero (used to be “Siberian ginseng” - don’t use with high blood pressure!) may all help to improve energy. A good start may also be as simple as a good multivitamin!
For more information about the causes and treatments for fatigue, see our Fatigue Fact Sheet on the NYBC website.
What supplements can I use to stabilize my weight?
For those experiencing weight loss, whey proteins, carnitine and creatine plus CLA may all help - but of course especially in conjunction with a good diet and routine exercise! And we agree with Dr. Jon Kaiser and many others: resistance exercise remains an important component of a successful HIV management plan.
What supplements are used to treat nausea?
NYBC recommends ginger; marijuana, while effective, is not carried by the NYBC, as it is not yet approved for medical use in New York. For detailed information about the causes and treatments for nausea, see Health+HIV section of Recommended Reading on the NYBC website.
What supplements are used to improve liver function?

Liver function can be impaired due to several reasons, including disease, alcohol abuse, and the effects of some cholesterol-lowering drugs (statins).
While making sure there aren’t any interactions with your meds, supplements like milk thistle (Silymarin), NAC, alpha lipoic acid, Hepato-C or Hepato-Detox, Hepatoplex I or II, Ecliptex, SAM-e and Clear Heat are options to consider (again, not all at once!)
What supplements can be used to treat diarrhea?
NYBC suggests supplementing your diet with glutamine and calcium. For more information about the causes and other possible treatments, see our Fact Sheet about diarrhea in Recommended Reading, at www.newyorkbuyersclub.org.
What supplements can combat neuropathy?
Much scientific evidence now points to acetylcarnitine as an effective approach to countering neuropathy (numbness, tingling, or pain, usually in the extremities, which can be caused by HIV, diabetes or by some medications).

Our friends at the Canadian AIDS Treatment Information Exchange (CATIE) have released a noteworthy new publication, freely available online:

A Practical Guide to Nutrition for People Living With HIV

CATIE has a long-standing interest in nutritional supplements and HIV, and maintains on its website a collection of info sheets on a variety of relevant topics, from individual supplements to managing and preventing side effects of HAART with supplements.

This newly-issued guide brings together a wealth of accumulated knowledge in a very readable format, so overall we recommend it highly.

In the section on Vitamins, Minerals and Supplements, the new guide gives an overview of the following topics:

–micronutrient deficiencies and HIV

–antioxidants and HIV

–key vitamins and minerals for people with HIV (B vitamins, vitamins C, D, E, Calcium, Iron, Zinc, Selenium)

–other supplements used by people with HIV (alpha lipoic acid, carnitine and acetyl-l-carnitine, NAC, glutamine, probiotics, and CoQ10)

Very useful is the chart summarizing recommendations and dosing for these supplements, especially in light of more recent findings, which, for example, lead to the recommendation of a higher daily dose for Vitamin D (1000 IU), and more caution in the use of some items (such as Vitamin E and Zinc).

In addition to these pages on nutritional supplements for HIV, we also recommend the guide’s sections on “Managing the Effects of HIV and Meds on the Body,” “Managing Symptoms and Side Effects,” and “Hepatitis C Co-infection.”

Oh, and by the way: “Appendix D: Web Resources” gives a listing for the NYBC website:

Here’s an article from 2004. 

Note the combination of probiotics, soluble fiber, and glutamine used:

Carla R. Heiser, MS, RD, LD Center for Functional Nutrition, Advocate Illinois Masonic Medical Center, Chicago, Illinois, USA ; Judith A. Ernst, DMSc, RD Indiana University, Indianapolis, Indiana, USA; James Tom Barrett, MD Howard Brown Health Center, Advocate Illinois Masonic Medical Center, Chicago, Illinois, USA; Neel French, MD  and Malte Schutz, MD Howard Brown Health Center, Advocate Illinois Masonic Medical Center, Chicago, Illinois, USA; Michael P. Dube, MD Indiana University, Indianapolis, Indiana, USA

Purpose: Highly active antiretroviral therapy (HAART) can be associated with diarrhea and other gastrointestinal (GI) side effects. Reducing these side effects may improve treatment durability and quality of life (QOL). This study assessed the impact of nutritional co-therapies known to reduce diarrhea in HIV-positive men treated with nelfinavir (NFV)- or lopinavir/ritonavir (LPV/r)-containing regimens. Methods: Thirty-five HIV-positive men treated with NFV (n = twenty-seven) or LPV/r (n = eight) with diarrhea (± two liquid stools/day [d]) participated in a 12-week prospective study. Twenty-eight subjects were randomly assigned supplements (S), seven received standard of care (C). Group S received probiotics (1.2g/d) and soluble fiber (11g/d). If diarrhea persisted at week 4, 30g/d L-Glutamine (GLN) was added. Diarrhea incidence, as well as supplement and antidiarrheal use, was assessed monthly. Results: Weight, CD4 count, and HIV RNA were unchanged in both groups. Diarrhea completely resolved in 10 of 28 (36 percent) S subjects. The mean (± SD) number of stools/d declined [3.40 ± 1.25 to 2.54 ± 1.34 (p < 0.01)]. Diarrhea (loose, watery stools/d) lessened in S from 2.84 ± 1.42 to 0.74 ± 1.03 (p < 0.0001). Fifteen S subjects did not obtain full relief with probiotics and fiber, but stools/d decreased from 4.08 ± 1.35 to 3.06 ± 1.68 (p < 0.05) after starting GLN. In C, stools/d, 4.14 ± 4.86 to 3.44 ± 1.68(p = 0.67 and incidence of diarrhea/d, 3.00 ± 4.82 to 1.36 ± 1.29 (p= 0.361) was unchanged. In S, loperamide use decreased from 1.69 ± 2.34 to 0.31 ± 0.69 mg/d (p < 0.01); 18 versus eight subjects used loperamide at 0 and 12 weeks, respectively. Conclusion: Probiotics, soluble fiber, and GLN significantly reduced diarrhea for subjects receiving NFV or LPV/r. Nutritional co-therapies show clinical benefit in HIV-positive men with diarrhea.
