Glutamine is an amino acid that serves as a building block for proteins. It is also an important fuel for immune cells that promote optimal immune function.
What Is L-Glutamine?
Glutamine supplements are often associated with serious athletes, but it can be beneficial for anyone who wants to not only maintain muscle health, but also immune and gut health.
Glutamine is the most abundant free amino acid found in the body.
L-Glutamine Benefits
- Supports healthy muscle mass
- Helps maintain energy levels under heavy stress
- Helps maintain optimal immune function & gut health
Glutamine can be found circulating in the blood, as well as stored in the skeletal muscles and liver, in concentrations ranging from 10- to 100-fold higher than any other amino acid.
Glutamine is utilized in a number of vital functions, including protein synthesis and production of the nucleotide units that make up DNA and RNA. Because of its importance in many cellular functions, glutamine is consumed at especially high rates during activities involving intense exercise. It is an important energy source for cells lining the gut and immune cells and critical for healthy gut and immune function. It is also a precursor of the brain neurotransmitter glutamate.
The function of glutamine in stimulating glycogen synthase, the enzyme that controls the synthesis and storage of glycogen fuel in muscles and liver, may provide a mechanism by which glutamine supplements promote enhanced fuel stores.
People who engage in heavy exercise can affect their glutamine levels, causing stress to their body and immune systems. Supplementing with glutamine can be important to a serious athlete, someone challenged with muscle loss or someone who wants to help maintain optimal immune function and energy level under heavy stress.
Studies indicate supplementing with glutamine can effectively raise glutamine concentrations in circulation and in muscle tissue, promote a healthy inflammatory response and support antioxidant defenses to maintain muscle health.

FAQ
What is in Creatine Powder?
Each scoop of this powder supplement contains 5 grams of creatine monohydrate, a well-studied amino acid derivative for muscle strength and recovery support.
Who is Creatine Powder intended for?
Creatine Powder is intended for individuals who want to support muscle function, exercise performance, and energy metabolism by supporting ATP (adenosine triphosphate) production, the cells’ primary source of energy.
Is creatine monohydrate beneficial for women?
Yes! Studies show that creatine supplementation may help improve strength and exercise performance throughout hormone-related changes in pre-and postmenopausal women.
Creatine monohydrate vs. micronized
Both forms of creatine support muscle strength, stamina, performance, and recovery. The only difference between creatine monohydrate and micronized is the particle size. Micronized creatine is processed into smaller particles that may help dissolve it faster, but there is no evidence that it’s more effective than regular creatine monohydrate. Our Creatine Powder is unflavored and mixes easily into 8 ounces of water or your choice of beverage.

The body produces creatine primarily in the liver and kidneys from the amino acids arginine and glycine, with help from S-adenosylmethionine. Creatine circulates through the bloodstream to help support energy for cells throughout the body, but healthy levels tend to decline as we age.
Lean muscle mass, exercise performance and recovery
Creatine is one of the best-studied nutrients for lean muscle mass, strength, and power. It is a staple of both professional and amateur athletes, and a must-have for almost any regular exercise routine.
Cellular energy production
Creatine helps cells produce their primary source of energy, ATP (adenosine triphosphate), which is essential for supporting an array of biological processes that keep you healthy. In the body, creatine helps recycle ATP to create energy that cells can use.
Creatine and women
Women have 70-80% lower internal creatine stores than men and may consume lower dietary amounts of creatine. And during times of hormone-related changes, creatine kinetics may be altered in the body. Creatine supplementation may help improve strength and exercise performance throughout these changes, in both pre- and postmenopausal women.
Creatine as you age
Numerous clinical trials have demonstrated creatine has positive effects on upper and lower body strength, physical performance, and body composition and supports muscular performance in older adults, especially when combined with resistance training, with best effects generally seen after 12 weeks.
Add this easy-mix, unflavored powder to eight ounces of water, a protein smoothie or your preferred beverage. Supplies 5 g of easily absorbed creatine monohydrate in every scoop.
