Some individuals will look for specialized diet programs to achieve their goals while some will look for certain supplements to aid in their health goals. One such supplement is known as Amino Acid Supplements. But does amino acid help you lose weight? In this article, we will see the different types of amino acids that are beneficial for weight loss.

Does Amino Acid Help You Lose Weight? A Brief Overview

People who have come across amino acids may ask what they are for and what they can do for the body. As it turns out, Amino acids are protein’s building blocks. These are compounds that are organic and are used in the different biological processes and they are the main components of protein. When protein is processed or digested by the body, they are broken down into amino acids. Some of these amino acids can make the body more efficient in burning fats and improve the growth and development of muscles. This is also the main reason why people take protein shakes as these shakes can be processed by the body and converted into amino acids for muscle repair and growth.

Amino Acids And Weight Loss

Not all amino acids are created equal and some are better than others in promoting weight loss and stimulating muscle growth. Detailed below are some of the best amino acids for people to lose weight:


L-carnitine is a type of amino acid that is popular in supplements that claim to support fat burning. It is also a form of an amino acid known for aiding the body in the production of energy. The amazing thing about L-carnitine is that it can enhance the utilization of stored fats as a form of fuel and can also help in improving mental health and lowering the fatigue felt by individuals.

L-carnitine is another amino acid to help you lose weight as it can transport body fat to the Mitochondria where it can be processed as form energy to produce ATP. Once this occurs, the body’s mitochondria can be likened to a furnace that can efficiently burn fats. Individuals who train at around 75% of their actual physical capacity, L-carnitine can shift from using glycogen from carbs to fats stored to fuel physical activities. This means that more fat is used up coupled with improved energy levels.

Through the use of L-carnitine supplements, the body can better use up stored fats as a source of fuel after and during any physical activity such as exercise. The other benefits of L-Carnitine include reduced fatigue and improved levels of energy.

Some of the food items that contain significant amounts of L-carnitine are seafood, pork, chicken, and red meat. L-carnitine can also be acquired through other vegetarian sources such as Brussel Sprouts, Brocolli, Beet Greens, asparagus, and artichokes


This amino acid can elevate the production of nitric oxide in the body which is a compound that can act as a synaptic messenger for the nerves, also known or referred to as a neurotransmitter. Healthy levels of nitric oxide in the body can help in the maintenance of a nervous system that is efficient and healthy. The weight loss assistance offered by L-Arginine is that it offers individuals a chance to healthily lose weight. This is because L-arginine, as an amino acid, can promote fat burning while ensuring that lean muscle is retained. L-arginine aids in the regulation of hormones as well which can enhance the metabolism of fat and increase the body’s sensitivity to a hormone known as Lipase which is responsible for the breakdown of fats as well. A clinical study conducted on L-Arginine showed that when taken together with a healthy diet and regular exercise, this amino acid can promote better weight loss than with exercise and diet alone.

Vegetarian food sources such as watermelon seed kernels, squash seed kernels, pumpkin seed kernels are rich in L-arginine. Other food items that have significant amounts of L-Arginine include:

Plant-based  Fish and Seafood Poultry Meat
  • Lentils
  • Peanuts
  • Chickpeas
  • Mung beans
  • Soybeans
  • Pumpkin
  • Watercress
  • Spinach
  • Cod
  • Shellfish
  • Mollusks
  • Crustaceans
  • Duck
  • Chicken

One of the most numerous amino in the human body, glutamine is a form of amino acid that is non-essential. This means that the human body can naturally produce it.

When people exercise and after any exercise routines, the glutamine stored in the body is used up which means more glutamine is used up than what can be produced by the body.

Glutamine may be beneficial to weight loss. In one study, women who took glutamine supplementation experienced sustained weight loss compared to those who did not take the same supplement. In fact, test subjects who ceased taking glutamine lost the weight loss effects of the supplement.

Glutamine can also help individuals better recover after any physical activity or exercise. It can help restore utilized glutamine and maintain lean muscle. People who are obese or overweight will need more glutamine than those who are already of normal weight. If the body lacks its required glutamine, the body will use up muscle to get the amino acid it needs and as such, muscle mass is lost. Another amazing benefit of glutamine is its ability to help individuals control cravings and hunger particularly cravings for sugary foods

Some of the food items that have significant amounts of Glutamine include:

  • Eggs
  • Dairy products
  • Chicken
  • Beef

Glutamine can also be acquired through other vegetarian food sources such as kale, celery, papaya, parsley, carrots, spinach, cabbage, beets, and beans.
