: Glutamine and recovery

L-glutamine and recovery | Holland & Barrett	However, there's far more to it than that. Glutamine significantly affects BCAA metabolism, gut barrier maintenance, normal immune function, glucose formation, water transport, neurotransmission, and more. Your kidneys are a primary consumer of glutamine use that's where the ammonia cleaved from glutamine works to maintain your body's acid-base balance. Anywhere you find ammonia, you'll find glutamine. As metabolic acidosis increases—as in response to intense training or a high-protein diet—renal uptake of glutamine soars. In fact, one study found that just four days of a high-protein, high-fat diet, was enough to cause a 25 percent drop in glutamine levels in the plasma and muscle tissue. If all of these competing uses begin to outpace your body's ability to produce glutamine, then you may start to show signs of deficiency, including muscle wasting, depleted energy, and increased susceptibility to infections. Despite glutamine's various functions, little evidence suggests it will directly result in increased muscle mass, reduced body fat, or gains in muscle strength or power in normal, healthy people. However, given how stressful intense training is on the human body, athletes may see certain benefits from supplementing with significant levels of glutamine, or from stacking it with other supplements. One study found that when athletes suffered from mild dehydration, supplemental glutamine increased exercise performance and enhanced fluid and electrolyte uptake when combined with a glucose and electrolyte beverage. Supplementation has also been shown to raise levels of growth hormone in response to cycling to exhaustion. Extracellular concentrations of glutamine have also been shown to activate the signaling pathway mTOR, which is known to be responsible for increasing muscle size. However, here again, the benefits of glutamine supplementation required that other conditions be met: in this case, mTOR signaling appeared to require the presence of BCAAs leucine, most importantly , as well as some threshold level of cellular hydration. In another case, collegiate track and field athletes who consumed four grams of glutamine per day for eight weeks, along with a loading and maintenance dose of creatine, saw greater gains in lean body mass than those who used creatine alone. This may sound significant, but it's hard to draw conclusions over a mere eight weeks at such a low dosage. Whether higher doses or a longer study would have resulted in significant differences is anyone's guess. Other than your stack, the most important thing to consider when selecting a glutamine product is the delivery system. If you're purchasing a powder, capsule or tablet, then free form L-glutamine works best. However, because glutamine is unstable, avoid ready-to-drink beverages or protein bars claiming to contain supplemental L-glutamine. If you favor RTDs and bars, look for the peptide-bound forms of glutamine, such as L-alanyl-L-glutamine, glycyl-L-glutamine hydrate, or an ingredient listed as "glutamine peptide. In other words, there's only about 6. Dose accordingly. Regardless of the form, up to 90 percent of ingested glutamine is eliminated during first pass. A mere fraction of the glutamine you consume will make it beyond your liver. The majority of the glutamine you consume being eliminated by the digestive enterocytes and immune cells within your gut. It's best to avoid products that contain n-acetyl-l-glutamine not to be confused with N-acetyl glucosamine or alpha-ketoisocaproyl-glutamine also known as aKIC-glutamine. Both the acylated and aKIC forms may be stable, but the existing evidence suggests that they're both poor delivery forms for glutamine. Consider stacking glutamine with sodium and other electrolytes first and foremost. Glutamine transport occurs via a sodium-dependent mechanism, and it has been shown to significantly increase cell volume, electrolyte absorption, and hydration. This might be helpful for both endurance and physique athletes, the latter because cell water volume is one of the many aspects of muscle hypertrophy. Significant decreases in cell water volume can also inhibit mTor signaling, which is crucial to building muscle. It appears that the daily intake of supplemental glutamine needs to be high—at least g per day, consumed frequently—in order to raise plasma glutamine concentrations. To provide some perspective, consider that critically ill patients usually receive a constant intravenous infusion of between g of glutamine per day. However, the bioavailability of infused glutamine they receive is percent. It's no more than 30 percent from orally consumed glutamine. Thus, I recommend up to 30g of glutamine per day in divided doses throughout the day, preferably with meals or snacks containing carbohydrates to support glucose utilization. On training days, I recommend you consume glutamine prior to or during exercise to support hydration, electrolyte transport , and BCAA metabolism. You could take 10g before, during, and after your workout, or you could reduce those dosages to 5g if you also dose in the hours leading up to or following exercise. On non-training days, consume at least 5g of glutamine at frequent intervals, at least every hours, to sustain an increase in plasma glutamine concentrations. There appears to be no need to cycle glutamine. Pakd Sports Nutrition Glutamine. Confident Sports Glutamine. Believe Supplements Fermented Glutamine - Unflavoured.

Glutamine and recovery -

Additionally, it is important for the normal growth and maintenance of the cells in the intestine 6 , Due to the major role of the intestines in the immune system, glutamine may benefit your overall immune health by supporting the intestinal cells 19 , Summary Your intestines are a major part of your immune system.

Glutamine is an energy source for intestinal and immune cells. It also helps maintain the barrier between the intestines and the rest of your body and aids with proper growth of intestinal cells.

Due to its role as a building block of protein, some researchers have tested whether taking glutamine as a supplement improves muscle gain or exercise performance.

In one study, 31 people took either glutamine or a placebo during six weeks of weight training By the end of the study, both groups showed improved muscle mass and strength. However, there were no differences between the two groups. Additional studies have also shown that it has no effects on muscle mass or performance 30 , However, some research has reported that glutamine supplements may decrease muscle soreness and improve recovery after intense exercise In fact, one study found that glutamine or glutamine plus carbohydrates can help reduce a blood marker of fatigue during two hours of running It has also been used to try to boost the immune function of athletes, but results vary 34 , 35 , Other research has found that it did not improve the recovery of carbohydrate stores glycogen in muscle when added to carbohydrates and certain amino acids In the end, there is no evidence that these supplements provide benefits for muscle gain or strength.

There is some limited support for other effects, but more research is needed. Summary There is little support for the use of glutamine supplements for muscle gain or strength performance.

However, they may reduce fatigue or decrease muscle soreness during and after exercise. It has been estimated that a typical diet may contain 3 to 6 grams per day, although this amount could vary based on the types and quantities of foods consumed Studies on glutamine supplements have used a wide variety of doses, ranging from around 5 grams per day up to high doses of approximately 45 grams per day for six weeks Although no negative side effects were reported with this high dosage, blood safety markers were not specifically examined.

Other studies have reported minimal safety concerns regarding short-term supplementation of up to 14 grams per day Overall, it is believed that the short-term use of supplements is likely safe. However, some scientists have raised concerns about their sustained use Adding glutamine to a regular diet may cause a variety of changes in the way the body absorbs and processes amino acids.

Yet, the long-term effects of these changes are unknown Therefore, more information is needed concerning long-term supplementation, particularly when high doses are used.

It is possible that glutamine supplements may not have the same effects if you eat an animal-based, high-protein diet, compared to a plant-based, lower-protein diet. If you follow a plant-based diet with low glutamine content, you may be able to consume supplements while still receiving a normal daily amount of it overall.

If you decide to take a glutamine supplement, it is probably best to start with a conservative dose of around 5 grams per day. Summary Intake of the glutamine found in foods, as well as the short-term use of supplements, is safe.

However, glutamine supplements can affect how your body processes amino acids. More studies on their long-term use are needed. L-glutamine is the important form, which is produced naturally in the body and found in many foods.

It is estimated that a typical diet contains 3 to 6 grams per day. It provides fuel for immune and intestinal cells and helps keep the connections in the intestines strong. During times when your body cannot produce optimal amounts, such as during injury or severe illness, supplementing with it may be beneficial for your immune health and recovery.

Glutamine is also frequently used a sports supplement, but most research does not support its effectiveness. Supplementing appears to be safe in the short-term, but more research is needed on its long-term effects. Before taking a glutamine supplement, consider whether the reason for taking it is supported by current evidence.

There appears to be no need to cycle glutamine. In fact, there's more evidence to support the need for chronic ingestion of glutamine during periods of extreme physiological stress.

There's a considerable amount of data supporting the lack of adverse reactions to glutamine doses as high as 30g per day. A recent week toxicity study concluded that the "no-observed adverse effect level" NOAEL for L-glutamine occurred at the highest daily dose provided to male and female rats.

In a human, this dose equates to roughly 0. For a pound adult, that's a little more than 52g of glutamine per day. Again, this dose was shown to result in an extremely high level of safety with no documented adverse effects. Yes, glutamine is a key player in a whole host of functions that dramatically impact your ability to achieve your overall health and fitness goals.

However, if you're depending solely upon glutamine or aren't using enough, you may be disappointed. Maximizing glutamine's effects on your body requires you to use your head first.

If you're not training hard, your body probably can supply you all you need. But if you're the type who punishes your body regularly, taking it in the right way could help you keep performing at an elite level.
