All About Glutamine | Daily Intake Requirement


There are plenty of various sports supplements on the market, but only a limited number of those actually have proven beneficial effects. Here, we shall examine why glutamine is beneficial, as well as how and how much it should be taken.


What Is Glutamine?

It is a substance from the class of conditionally essential amino acids and is an integral part of protein. It means that only a certain part of glutamine is synthesized by the body, so it does not cover all the need for it.  The other part should be obtained with food. Another argument for its importance is its share among all amino acids, which is about 60%.

Beneficial Properties

Some athletes regard this supplement rather skeptical, but here are its effects, to clear up any doubts:

  • strengthening of the immune system;
  • elimination of fat metabolism products;
  • liver fat deposition slowing;
  • binding of ammonia;
  • acceleration of recovery processes after physical exertion;
  • growth hormone levels increase;
  • lowering of cortisol secretion;
  • acceleration of protein synthesis due to the supply of muscle with nitrogen.

Intake Options

It’s better to determine the purpose of training before starting to take it. There are two options here:

  1. Ripping. Experiments show that taking glutamine in the context of aerobic exercise contributes to reduction of adipose tissue. The key to success is to make maximum emphasis on problematic areas and take the supplement in correct doses.
  2. Building muscle. Versatility is a feature of glutamine. It has a complex effect and is suitable for almost all athletes, beginners and professionals alike. It is due to the fact that muscles require timely restoration of glutamine regardless of the type of activity. 

If there is a shortage in glutamine, the risk of injury increases, rate of muscle growth decreases and catabolic processes begin. Moreover, deficiency of this amino acid leads to overtraining and a decrease in immunity. All this explains the importance of taking glutamine against the background of training.

Daily Dosage

Professional athletes claim optimal dosage to be 8-20 grams of glutamine daily. The more specific amount depends on several factors, like physical condition of the athlete, frequency of workouts, diet, etc. In some cases, the dosage can be increased to 30-40 grams daily, but gradually.


There are two main regimens of taking this supplement:

  1. The first one is to take amino acids in equal doses for each day (2-4 grams). Such amount is enough to maintain a relatively high level of glutamine. The supplement is supposed to be taken 3-4 times per day.
  2. The second one is to take the supplement on workout days. In this case glutamine should be taken before and after workout, and also before bedtime. For example, a portion of glutamine of 6-10 grams is taken prior to workout and right after it. The portions are washed down with liquid or together with protein shake. It is important, however, to take glutamine apart from other amino acids. In other cases, the result may be worse.

How much glutamine is needed on a low carb diet? In this case, the dosage should be increased to 25-30 grams daily to minimize the risk of catabolism. Otherwise, the body may not have enough carbs, and it will resort to using amino acids from the muscles. By the way, studies proved that about 30-40 grams of glutamine stimulates the immune system.

Where To Get Glutamine

There are two ways of getting glutamine – from food and from supplements. In the first case, the total amount of food consumed should be increased. 100 grams of beef contains about 3 grams of glutamine, cheese – 4.6 g, eggs – 1.7 g, high fat cottage cheese – 2.4 g, sea bass – 2.8 grams etc. In other words, it’s rather challenging to get a daily dose of 20-30 from food alone.


Glutamine In Action

The purpose of it is to provide a swift recovery after intense workout. For the tired and exhausted muscles, it’s one of the best remedies around. There are three major effect:

  1. strengthening of the immunity. In periods of increased stress, it’s a rather important thing;
  2. increase in performance during workout. The supplement allows to train longer and with more intensity;
  3. acceleration of recovery processes and muscle growth.

It acts as a sort of «restorer», which makes it possible not to worry too much about possible decrease in performance or health issues related to training stress.
