Optimizing Muscle Health in Aging Adults (Part 3)
For those of you that were wondering where the third part of this series was and if we were math challenged not to fear, Glutamine is here. Pardon the bad rhyme and without further ado here we are:
Glutamine - Progressive Labs
Glutamine is required for countless functions in the human body including maintaining muscle tissue and supporting immune system function. Glutamine is a conditionally essential amino acid, meaning that the body requircs dietary or supplemental glutamine during stressful circumstances such as prolonged exercise, surgery, or Infectious disease. Compelling evidence suggests that glutamine may be especially important for adults seeking to preserve lean tissue mass.
Glutamine is the most abundant amino acid in the body, and is highly concentrated in the skeletal muscles that make movement possible. Maintaining healthy skeletal muscle is essential to overall good health and mobility. Important research shows that glutamine can help maintain healthy muscle mass in people who are susceptible to loss of lean body mass, such as those undergoing surgery. One study showed that supplementing individuals who had major surgery with glutamine prevented the decline in muscle glutamine levels and muscle protein synthesis that can occur following such a procedure. These findings strongly suggest that glutamine can prevent the loss of muscle tissue during recovery from surgery and have important implications for all those seeking to preserve lean muscle mass.
Glutamine may offer benefits for muscle health by increasing growth hormone levels. Since youthful levels of growth hormone are associated with tissue building and repair, nutritional scientists have long sought methods of naturally enhancing growth hormone levels. In one study, scientists administered 2.000 mg of glutamine dissolved in a beverage to nine healthy adult subjects, Eight out olfthe nine subjects responded lo the oral glutamine intake with a four-fold increase in growth hormone output. These results bode well for athletes and active aging populations seeking to optimize their growth hormone levels.
Glutamine may hold important benefits for individuals who participate-in exercise training programs. Evidence suggests that glutamine may help replenish muscle glycogen stores after intense exercise.” Glycogen serves as a readily available form of fuel to power muscle action and as most athletes know, optimizing glycogen levels is important when you want to perform well.
Scientists administered glutamine to six healthy volunteers who bad just completed 90 minutes of intense exercise. Such vigorous activity depletes muscle glycogen stores. Glutamine administration increased muscle glutamine stores and increased glycogen storage alter the intense bout of exercise. While scientists are continuing to explore glutamine’s mechanism of action in increasing glycogen stores, this might just be one more benefit of this amino acid for athletes and aging populations who wish to remain active and healthy.
In addition to its benefits for muscle wellness, glutamine is also crucial for immune health, and may be especially crucial in those who exercise vigorously. Intense exercise is known to reduce glutamine stores. making less glutamine available for supporting healthy immune system Function and leaving individuals susceptible to infections. Scientists have proposed that supplementing with glutamine may help prevent the depression of immune function that can occur in those who participate in vigorous exercise programs.
Glutamine thus holds important benefits for preserving muscle mass with aging, supporting healthy growth hormone levels, optimizing muscle glycogen levels, and preventing exercise-induced immune suppression. These effects have important applications for athletes and aging populations who realize muscle is essential for healthy living and long-term functionality with advancing age.
Conclusion
The combination of whey, creatine, and glutamine powerfully supports aging muscles. Functional strength, and the aging immune system, all of which are critical factors for an active, independent life. Utilizing whey protein as a meal replacement provides critical proteins without the carbohydrates and kits that may contribute to unwanted weight gain.

Optimizing Muscle Health in Aging Adults Part 1
Happy New Year to each of you. We’re starting off the year focusing on muscle health in a three part series on “Optimizing Muscle Health with Whey, Creatine and Glutamine”. Thank you to Will Brink and the folks at Nutrition Dynamics for some good research in this area. Let’s dive in:
Many people associate protein supplementation with bodybuilders or professional athletes seeking rapid gains in muscle mass and strength. As we age however, remaining active and independent also requires strong, healthy muscles, especially since aging increases susceptibility to loss of muscle mass and muscle atrophy.
Fortunately, health-conscious adults are discovering the benefits of a combination of nutrients that can help them get the most from an active lifestyle as they get older. In order to help offset the age-related loss in muscle, whey protein offers a rich source of essential amino acids that are rapidly absorbed and utilized, helping to maintain healthy muscle. Utilizing whey protein as a meal replacement provides critical proteins without the carbohydrates and fats that may contribute to unwanted weight gain.
Two other nutrients complement the muscle-building effects of whey: creatine supports muscle strength and prevents muscle wasting with aging, while the amino acid glutamine helps preserve lean tissue mass and supports immune system health.
Together, these nutrients in combination powerfully support aging muscles, functional strength, and the aging immune system, all of which are critical factors for an active, independent life.
Whey Protein
Whey is a protein complex derived from milk with a diverse range of health benefits. Whey protein has long been a staple supplement for athletes, and is now gaining popularity among a wider population of health-conscious adults, and for good reason. It is a great protein with a wide variety of benefits, ranging from promoting muscle health to immune modulation to protection against cardiovascular disease and cancer.
Whey protein is a rich source of the essential amino acids in higher concentrations compared with vegetable sources such as soy. Compared with other protein sources, whey contains a high concentration of branched-chain amino acids, which are important for tissue growth and repair. Additionally, whey is rich in the sulfur-containing amino acids, which enhance the body’s antioxidant protection through intracellular conversion to glutathione. Other constituents of whey include beta-lacto-globulin, lactoferrin, and immunoglobulins, which hold important benefits for immune support.
Whey’s amino acids are rapidly absorbed and utilized. Quickly elevating plasma amino acids and thus contributing to the preservation of muscle mass. Studies show that whey protein helps augment the effects of resistance exercise training, particularly when it is consumed shortly before or after exercise training. In one study, 36 men followed a weight-training program for 12 weeks while supplementing with whey protein, a multi-ingredient whey protein supplement, or maltodextrin placebo. At the study’s end, men who supplemented with whev in combination with resistance training showed improvements in one or more measures of muscle strength as well as lean tissue mass, compared to placebo recipients.
Whey’s benefits for skeletal muscle go beyond those provided by its essential ammo acid content, promoting greater muscle accrual than that which occurs from ingesting the essential amino acids alone. As a rule. higher biological value proteins such as whey are superior for maintaining muscle mass compared with lower -Quality proteins, which may be of particular importance to older individuals. In fact, data suggest “fast” digesting proteins such as whey may be superior to other proteins for preserving lean body mass in older individuals. This suggests that whey holds practical applications in supporting muscle anabolism (tissue-building) in older individuals.
One of whey’s major effects is its ability to raise levels of glutathione, a powerful intracellular antioxidant. The importance of glutathione for good health cannot be overstated. Glutathione is arguably the most important water-soluble antioxidant found in the body, participating in crucial detoxification reactions in the liver. Glutathione is known to be essential to immunity, body antioxidative capacity, and general well-being, and decreased levels of glutathione arc associated with a long list of ailments such as neurodegenerative disease, cirrhosis, and the aging process itself. Boosting glutathione levels through whey supplementation may thus be beneficial for aging populations looking to avert disease and stay healthy and active.
A growing body of research suggests that whey protein may offer protection against some of the most prevalent diseases afflicting older adults. In animal and human studies, whey protein shows promise in the prevention and management of cancer. Whey may offer benefits for cardiovascular health by modulating blood pressure and promoting healthy blood lipid profiles. Supplementing with whey protein may be particularly important for those with immune health concerns as studies point to its ability to help light numerous bacterial infections as well as provide support for individuals fighting hepatitis C and HIV infections. Finally, human research has found that whey protein improves cognitive ability and helps improve coping ability in highly stressed individuals, possibly by providing tryptophan, the precursor to serotonin.
Whey’s benefits thus extend far beyond healthy muscles to overall effects in promoting a healthy body and mind. Pickup some today from our convenient online store:
