EAA Supplements – Essential Amino Acids for Your Body

When considering amino acid supplements, you should know that there are nine essential types which should always be included in your diet for proper health. These nine essential amino acids can be taken in the form of supplements or from food sources such as eggs and animal meat.

In case you were wondering, the nine amino acids generally regarded as essential for humans are:

  1. Threonine
  2. Phenylalanine
  3. Valine
  4. Leucine
  5. Tryptophan
  6. Methionine
  7. Lysine
  8. Isoleucine
  9. Histidine

Why are essential amino acids important?

Our bodies use them to build the proteins necessary for everything from muscles and bones, tendons and ligaments, skin and hair, internal organs and fluids, proper functioning of the immune system etc. They are also essential for the growth, maintenance, and repair of all these important parts of our bodies. This means they are essential for sustaining our lives!

Should you lack one or more of these essentials, some symptoms you may experience can include:

• Weakness and fatigue • Lack of energy • Abnormal loss of weight • Muscle loss • Frequent bodily infections or illness due to decreased activity from the immune system

You can counter some of these symptoms easily by taking supplements or by changing your diet to include more foods which contain the necessary proteins.

Who should take amino acid supplements?

The problem with eggs and animal meat intake is that there are some people who are vegans or vegetarians. Vegetarians and vegans are much more susceptible to the protein deficiency symptoms. If you are a vegetarian type, you should know that ingesting plants usually lack at least one of the essential amino acids – also, some plants are deficient in all nine. Therefore, people with these characteristics may want to take supplements in order to ensure their bodies are getting the sufficient amount to function properly. Also, women who are “too thin” or who are very conscious of their weight and should also consider taking amino supplements.

Athletes or body builders should really look into taking additional amino supplements. As stated earlier, amino acids are essential in the formation of proteins which build everything from muscles to stronger bones. Without them, athletes and body builders are limiting their performance or gains in a muscle building regime. Athletes and body builders naturally deplete amino acids from foods much quicker than the average person; therefore supplementation may help them tremendously in their routines. Three of the most important amino acids are valine, leucine and isoleucine because they maintain muscle tissues and prevent the breakdown of muscle during strenuous exercise. Many athletes have taken these specific amino supplements to improve and enhance their physical effects and performance.

For others who are undergoing stress, aging, infections, medication effects, and chemical imbalances, a decrease in amino acids may result and supplementation may be required. A blood test can detect a deficiency, but it is not always necessary as it can be corrected by taking supplements to ensure that you are getting the proper amount for your body and its functions.
