What are Amino Acids Good For?

Amino Acids

Ok, so you may be aware that there’s a lot of talk about amino acids these days and for good reason! That’s because they are essential for supporting good health and in synthesising proteins.

There are many amino acids but for the purpose of today’s blog I won’t mention them all (though we do talk about many).


This amino acid is involved in the biosynthesis of proteins and helps the body to convert glucose (great to help stabilise blood sugar levels for hypoglycemics). Not only that but it’s also used by the liver to help eliminate surplus toxins in the liver.

When taken with glycine and glutamic acid, alanine is known to support prostate health. It’s also been shown (through various research) that taking an oral dose of L-alanine (alanine) can be more efficient for insulin-dependent diabetics rather than reaching for a snack before bedtime.

Alanine is necessary for the metabolism of tryptophan (the amino acid needed in the production of mood-regulating serotonin). It (alanine) is also important for your body’s immune system because it produces antibodies.

Food sources for alanine

  • Meat, poultry, eggs and dairy products
  • Avocados, beans, bran, brewer’s yeast, brown rice, collagen powder, corn, legumes, mushrooms (raw), nuts, seeds, watercress, whole grains, and spirulina.


L-arginine (arginine) cannot be made by the body alone, we need to get it from the foods we eat and if we aren’t getting enough from those foods then it might be a good idea to take it in a supplement form.

The main benefit of L-arginine is it’s ability to help the body’s circulation of blood and the widening of blood vessels (therefore it may be of benefit to people suffering from Raynaud’s disease/phenomenon or peripheral circulation issues/disorders.)

Because the possible benefits are so many it’s hard to know where to begin?

  • Inflammation-fighter
  • May help to lower the risk of arteriosclerosis and heart attack
  • Blood vessel repairer
  • Lower blood pressure
  • Can help athletic performance
  • Increases immune function
  • Reduce muscle pain
  • Improve kidney function
  • Improve mental clarity and focus
  • Help to fight Dementia
  • Beneficial in correcting impotence, erectile dysfunction and male fertility
  • Useful for preventing the common cold
  • Can help fight effects of ageing

Food Sources for arginine

The most common food sources for arginine are beef, lamb, poultry, fish, eggs, hydrolyzed collagen and dairy (similar to many other amino acids).

Aspartic Acid

This amino acid is used by our body to generate adenosine triphosphate (ATP) which is the main cellular energy source.

Our bodies can produce aspartic acid so this one is not considered an essential amino. Just make sure that you’re getting enough though protein in your diet so that you don’t become deficient. If you need a protein boost try this.

For the synthesis of arginine, lysine, methionine, isoleucine and asparagine to occur, L-aspartic acid (aspartic acid) must be present.

Aspartic acid may be liver-protecting because it has hepa-protective properties (‘hepa’ meaning liver).

Food sources for aspartic acid

Foods such as asparagus, fish, soy and spirulina are good sources of aspartic acid and so is Hydrolyzed collagen.


This is another amino acid that can be synthesised by our liver so it’s not considered an essential one. However, in saying that, supplementation should be considered to cover your needs.

L-cystine contributes to overall well being because it helps to fulfil many important bodily functions. Chronic conditions such as cataracts and arthritis can be helped by the correct supplementation.

If you have a lot of stress (emotional/mental or emotional) this can actually use up more cystine therefore depleting your body of this important amino.

Extreme diets such as reduction diets can have a negative impact on both vitamins and aminos so proceed with caution if considering one of these diets.

Another potential benefit of L-cystine, is that it helps support synthesis of glutathione. Glutathione can be powerful for our immune health as it acts to strengthen it. It does this through inhibiting inflammation.

If you’re interested in ageing gracefully, you will be interested and excited to know that it’s also been shown to naturally slow down ageing (can I get a hell yeah?!?).

What else?

  • Improving hair & skin
  • Increase male fertility
  • Reduce inflammation
  • Preventing illness & disease
  • Combat osteoporosis

What food sources for cystine

Meats such as chicken and pork contain high amounts of L-cystine, and then raw salmon and eggs would follow closely behind. Make sure to source organic meat and wild salmon if possible.

Soy is the plant source but again, make sure it’s organic and non-GMO. The best sources of soy are organic tempeh and cooked soy beans. The problem with much soy on the market (unless certified organic) is that it is genetically modified (GM) and this has been believed to alter our DNA.

Hydrolyzed collagen powder is another source of cysteine (you get 4mg per serve).

Glutamic Acid

Glutamic acid is a non-essential amino acid that can be produced in the body with the aid of other amino acids. Glutamic acid plays an important role in the metabolism of sugars and fats and aids in potassium transport into the spinal fluid and across blood brain barrier and also acts as fuel for the brain.

This amino acid is beneficial for healthy brain function and it is mostly metabolised in the brain. If the person cannot produce the proper amount of glutamic acid, this can cause some serious brain disorders such as schizophrenia. Glutamic acid is also beneficial to mentally challenged individuals, those with muscular dystrophy and Parkinson’s Disease.

Food sources for Glutamic Acid

Foods such as soybeans, chicken, eggs, seeds, cheese, fish and hydrolyzed collagen powder.


This amino acid is useful for many different muscle, cognitive and metabolic functions. It aids in the breaking down and transport of nutrients such as glycogen and fat that are used as energy by the cells in our body. It supports a strong immune, nervous and digestive system. Glycine is found mostly in the skin, connective tissues of the joints and muscle tissue. This amino acid is one of the nutrients that gives bone broth it’s amazing healing component, considered as superfood.

Benefits of Glycine

  • Builds lean muscle mass
  • Important in the human growth hormone production
  • Improve memory and focus
  • Prevent strokes and seizures
  • Reduce joint pains and protect collagen in joints

This amino acid is essential to the body for bone, tendons, cartilage and skin strength. It is necessary in the strengthening and building of the body’s major structural protein which is collagen. When collagen is not well supported this can lead to gum and skin bleeding and symptoms of scurvy. A deficiency of hydroxyproline occurs only when there is lack of vitamin C in the body.

Food Sources

Hydroxyproline is a nonessential amino acid and is manufactured from other amino acids in the liver, this means that the body can produce it. This amino acid does not have to be obtained directly through the diet in order to be healthy, though you can get it from hydrolyzed collagen powder also.


This amino acid has the ability to increase endurance, repair muscle tissue and encourage clotting on the injury site. This is essential for athletes and bodybuilders because it primarily boost energy and help the body recover easily after physical exertion.

Isoleucine cannot be manufactured in the body and can only be acquired through food sources.


  • Keeps energy levels stable by regulating blood sugar

  • Leucine functions on the skeletal muscle through the two anabolic effects which are: protein synthesis stimulation and protein lysis inhibition.
  • Maintain muscle proteins  

Leucine is found in the following food source

High leucine foods include cheese, soybeans, beef, chicken, pork, nuts, seeds, fish, seafood, beans and again, hydrolyzed collagen powder.


Lysine is an essential amino acid used as building block by the body for many different functions essential for health maintenance and growth. This can’t be manufactured by the body unlike other types of amino acids.

Valine works well together with isoleucine and leucine to increase muscle mass especially for body-builders.

It is an amino acid used by bodybuilders because in association with other two amino acids – isoleucine and leucine – can help increase muscle mass.


This amino acid is helpful in giving the body energy that it needs, it also rebuilds muscle tissue, improve healing process of wounds, calm the nervous system, prevent stress and insomnia, increase physical strength, improve body’s metabolism and boost immune system.

Food Sources

The following are food sources of Valine

  • Soy
  • Grains
  • Peanuts
  • Mushrooms
  • Nuts, beans and sesame seeds
  • Spirulina
  • Dried Parsley
  • Pumpkin seeds
  • Dairy products
  • Fish
  • Eggs
  • Hydrolyzed collagen

So as you can see from this article, amino acids are very important for good health. They are used for so many functions and processes. You may have also noticed that one really simple way to get all the amino’s in one ‘foul swoop’ is to take them through a high quality hydrolyzed collagen powder such as the Perfect Hydrolyzed collagen.

The difference with this one and many other collagen supplements on the market is the way the cows are raised (pasture-fed, non-GMO and hormone/chemical-free), the product contains nothing else but pure collagen with no fillers or any nasties. It is also extracted through a safe enzyme bath process (unlike other collagens that are processed with acid).
