  • Fuel your active lifestyle—Glutamine is an amino acid your body uses for protein production. While it’s a must-have among serious athletes, glutamine is a great option for anyone who leads an active lifestyle
  • Gut healthy, immune strong—Glutamine can be found in the blood, as well as stored in the skeletal muscles and liver, and in higher concentrations than any other amino acid. It’s an important energy source for cells lining the gut and immune cells, making it critical for a healthy digestive tract and immune response.
  • Antioxidant support—Regular body movement is terrific for whole-body health. But engaging in heavy exercise can affect glutamine levels, causing stress to the body. Our L-Glutamine formula helps support antioxidant defenses to maintain muscle health.

Glutamine is the most abundant free amino acid circulating in the blood as well as stored in the skeletal muscles. Glutamine is a diverse amino acid that is utilized in numerous vital functions.

It is necessary for rapidly dividing cells, including those of the gut and immune system. It is also used as an energy source in mitochondria,180 and is a precursor of the brain neurotransmitter glutamate.

Glutamine is also needed for optimal nucleotide biosynthesis and protein synthesis. Glutamine is an important fuel for some immune cells, such as lymphocytes and macrophages, that may have specific immunostimulatory effects.

Quality and durable socks

Great quality socks. This pack was a lot taller on the cuff and bigger than previous batches I have had. Not sure what the change was, but giving it 4 instead of 5 because I preferred the smaller shorter ones they previously made. But these are great quality socks, and last a long time.

A Game-Changer for Comfort
Size: Medium, Color: Black, Number of Items: 6
I recently upgraded my workout gear with the Under Armour Training Cotton Quarter Socks, and I must say, these socks have revolutionized my exercise experience. Comfortable, durable, and stylish, they truly stand out in the crowded world of athletic socks. First and foremost, the comfort level of these socks is unparalleled. The blend of cotton and synthetic materials provides a soft and plush feel against my feet, making every step a pleasure. The quarter length strikes the perfect balance, offering ample coverage without being too restrictive or too short. It's like walking on clouds, even during the most intense workouts. One of the standout features is the moisture-wicking technology. I've worn these socks during high-intensity cardio sessions, and they have consistently kept my feet dry and comfortable. The breathability is remarkable, preventing that uncomfortable feeling of sweaty feet that often accompanies strenuous workouts. No more distractions – just focus on pushing through your fitness routine. Durability is another strong suit of these socks. After numerous washes, they maintain their shape and elasticity, showing no signs of wear and tear. The reinforced heel and toe areas provide extra support, ensuring longevity and preventing the dreaded sock holes that often plague other brands. The sleek design of the Under Armour Training Cotton Quarter Socks adds a touch of style to my workout attire. The subtle logo and choice of colors make them versatile enough to pair with any athletic shoes. Whether you're hitting the gym, going for a run, or simply running errands, these socks seamlessly blend fashion with function. In terms of sizing, I found that they fit true to size. The elastic band around the arch provides a snug yet comfortable fit, ensuring that the socks stay in place throughout any activity. While the price point may be slightly higher than some other options on the market, the quality and performance of the Under Armour Training Cotton Quarter Socks more than justify the investment. When it comes to comfort, durability, and style, these socks have become an indispensable part of my workout wardrobe.

Socks work really good. I have very rough and dry feet that tear up my bed sheets. They hold up to my destructive feet. They are soft and comfy!
