Glutamine vs Creatine

creatine vs glutamine

Glutamine and creatine are two supplements that people consume for workouts. They are most commonly used to aid muscle recovery and energy in athletes. However, both substances are very different. So, why is supplementation required, and how are they used?

What Is Creatine?

Creatine is a chemical produced from amino acids in your body, as well as being found in meat and fish. It’s a quick source of energy for muscles, but during exercise, its depleted instantly. This results in a decline in energy. Supplementing your diet with creatine helps to increase stamina, muscle strength and size. However, its best for short bursts of exercise, rather than for long-distance sports or events.

What Is Glutamine?

Glutamine is the most abundant amino acid found in the body. Like creatine, glutamine can be produced in the body and while its typically a non-essential amino acid, it becomes essential when the body is under stress and strain. Glutamine can aid the healing process, boost the immune system, and help muscles to recover after exercise. Glutamine can be quickly converted into glucose, forming a source of energy for cells. Many athletes supplement with glutamine to aid sports endurance, as well as maintaining muscle mass and growth.

Glutamine VS Creatine: Which Is Better?

The best supplement for you depends on your requirements. If you intend on using creatine or glutamine for endurance, then creatine is considered to be highly effective in this regard. Creatine helps to stimulate a molecule known as adenosine triphosphate or ATP. This is the body’s main energy source, and what is required when the muscles energy stores are depleted during exercise. Studies have demonstrated that creatine supplementation has positive effects during short-term exercise. Creatine works best for sports, such as weight-lifting and high-intensity training.

Glutamine also provides energy as it can quickly convert to glucose and is known to reduce signs of stress. During exercise or stress, levels of glutamine decrease1, thus, the body requires extra glutamine to allow the body to function correctly. Furthermore, glutamine aids detoxification of the liver to convert ammonia into urea. Created by the breakdown of proteins, ammonia prevents energy production and leads to a lack of sleep. Therefore, by aiding energy levels and sleep, the body is better equipped for physical performance.

Studies have demonstrated that glutamine helps to increase recovery time after strenuous exercise as it aids the resynthesis of carbohydrates. Studies have also revealed that glutamine supplementation reduces muscle soreness after workouts, as well as aiding the immune system during heavy load training. On the other hand, studies have suggested that creatine supplementation has no effect on muscle recovery from resistance exercise. So, creatine’s greatest benefit appears to be boosting energy in short-term workouts.

Can Creatine And Glutamine Be Used At The Same Time?

Both creatine and glutamine (or L-glutamine) are safe be taken together or stacked. Many supplement brands offer both substances together. However, those new to supplementation can stack creatine and glutamine together.

How To Use Creatine And Glutamine In Your Regime

To use creatine and glutamine in your daily routine, consider taking them post-workout. The University of Maryland Medical Center suggests use creatine supplementation in two phases. The loading phase involves taking 20g of creatine per day in 5g doses for one week. This could include morning, pre-workout, post-workout and evening doses. The maintenance phase involves consuming 2 to 5g of creatine per day for as long as its recommended by your doctor.6 However, 6 months is the suggested time limit.

If you’re new to glutamine, start with 2-3 grams per dose, working up to 5 grams. Those familiar with supplements should consider taking 7 to 10 grams per dose. The University of Maryland Medical Center suggest glutamine is safe in doses of up to 14g per day.
