Best Glutamine Supplements for Energy and Muscle Growth in 2021
If you haven’t heard of glutamine, you might be interested to know that it can be used to assist in recovery after exercise and muscle repair. In order for your body to synthesize or create muscle tissue, you must obtain adequate protein from the diet. Glutamine is an amino acid, or “building block” that makes up longer protein chains. Getting enough amino acids such as glutamine in your diet can help the body make enough protein to support muscle repair.
The scientific name for glutamine is L-Glutamine. This amino acid is one of the most abundant amino acids in the body. It can be found in a variety of sources including meat, eggs, dairy products, and to a lesser extent, whole grains and vegetables.
Our Five Best Recommended Glutamine Supplements
Why do People Take Glutamine Supplements?
Even after eating a normal, varied diet, some people still aren’t getting enough protein to adequately rebuild muscle tissue. Especially in times of high-stress, or increased exercise, this important nutrient may be lacking.
In is important to note that any supplement, including L-glutamine, is not a magic bullet for creating six-pack abs or mountainous biceps in a few weeks. Supplements are used to support and enhance a prudent, balanced diet and a consistent workout program. As with anything, results should not be expected overnight.

Glutamine isn’t necessarily known for its muscle-building capabilities. While studies have shown that people do gain some muscle mass while taking glutamine, it’s not a cause and effect relationship. Glutamine is better known for its ability to provide the body with energy and to aid recover from soreness following exercise. Exercise supplements are just that, they supplement your fitness and nutrition regimen to help increase muscle growth.
So what makes glutamine a popular additive to protein powders and exercise supplements?
- Prevents muscle from being broken down for fuel
- Muscle breakdown occurs when people exercise intensely and eat a poor diet
- Replenishes glutamine levels that are used up during exercise
- Gives you the energy to help you through high-intensity workouts
- Promotes intestinal and digestive system health
- A healthy digestive tract insures you are able to absorb all of the nutrients in your diet
Protein is an essential nutrient that we can’t live without. Adding protein powders to the diet can help people supplement the protein they are able to obtain from food and create in their bodies. Active, muscular bodies will have a higher protein requirement as more muscle tissue is maintained and rebuilt constantly in their bodies. These are the individuals that benefit the most with extra protein supplementation.
As with all supplements, too much of a good thing can be a bad thing. How much is too much? Pay close attention to the serving sizes and recommendations on the nutrition fact panel found on your supplement. Too much protein can be hard on the digestive system and won’t actually be metabolized and used by your body anyway.
It is never okay to neglect your diet and substitute real food for glutamine or any other supplement. All of the nutrients the body requires for optimal health must be found in a variety of healthy foods. A well balanced, prudent diet is always the best way to reach your fitness goals. L-glutamine is simply an extra tool that might help you reach those goals a little faster.
