Glutathione Precursors

You probably have heard of glutathione, an important antioxidant needed by the human body. However, how familiar are you with the glutathione precursors, the compounds that participate in a chemical reaction that produces glutathione?

Now, we are going to read through 3 glutathione precursors which are glutamate, glycine, and cysteine. These amino acids are also known as the building blocks of glutathione.


Glutamate isn’t merely one of the three glutathione precursors, it’s also a key molecule in cell metabolism. It is also the most abundant neurotransmitter in the brain. Glutamic acid is also present in various foods like cheese and soy sauce.

Monosodium glutamate is also a product of glutamic acid in form of its salt. There are 2 forms of glutamate, the bound form as a part of protein along with other amino acids and free form in plant and animal tissue.

Daily, an average person consumes between 10 and 20 grams of bound glutamate and 10 grams of free glutamate. In addition to that, the human body produces around 50 grams of glutamate daily. An abundance of glutamate is found in human breast milk; to the extent of 10 times the glutamate found in cow’s milk.

All meats, poultry, fish, eggs, unpasteurized dairy products, undernatured whey protein, and protein rich plants are all natural sources of glutamate.

Consuming them regularly is very important for our immune system since glutamate builds glutathione, which acts as the body immune system.


The second glutathione building block is the smallest of the 20 amino acids commonly found in proteins, called glycine. Glycine is produced in the body from the amino acid serine and threonine, but is also abundant in food.

Glycine is also found to be useful in assisting with absorption of calcium in the body. This amino acid is also important in the manufacture of hormones responsible for a strong immune system.

Glycine also plays an important role in helping slow down the degeneration of muscles since it helps to supply extra creatine in the body. In prostate fluid, large amounts of glycine are also found; indicating its vital role in prostate health.

By the industry, glycine is commonly used as a sweetener and taste enhancer while in antacids, analgesics, antiperspirants, cosmetics and toiletries, glycine acts as a buffering agent.

Food sources of glycine include abundant in high protein foods like fish, meat, beans, nut, and dairy products. Foods such as lean veal sirloin, mozzarella cheese, and lean round beef have the highest glycine content.


The third and last glutathione precursor is cysteine. Cysteine is also widely known as the most crucial component out of the three building blocks for glutathione. This means that the level of cysteine in your system is the limiting factor in how fast you can produce glutathione and how much of it you can make.

The antioxidant activity of glutathione is attributed specifically to the presence and availability of this amino acid. Patients with chronic conditions such as cataract or arthritis will greatly benefit from taking cysteine supplements. Even among healthy people, illnesses of the intestines usually increase the needs of cysteine.

Glutathione PrecursorsStress or physical strain will also lead to an increased demand in cysteine. However, don’t worry since our body produces cysteine from food sources such as all meats and poultry, fish, eggs, dairy, quinoa, buckwheat, sesame seeds, and Brazil nuts.

Meat and soy products are highly recommended as well, along with pork and chicken.

Appropriate intake of cysteine has also been proved to slow down the natural process of aging, preventing dementia, and multiple sclerosis.

Cysteine also contributes to healthier skin and hair, increasing male fertility, reduces inflammation and combats osteoporosis and illnesses. Lacking in cysteine, on the other hand, may result in infections, and in extreme cases, cancer.

Vegetables that boosts cell regeneration

Vegetables are extremely healthy for our health. Not only do they provide enough nutrients to our body but it also keeps our cells nourished. Green vegetables are rich sources of antioxidants that protect our skin cells from getting damaged in the sun.

Not only that, our skin is protected from the harmful germs and dead cells are removed.

The various enzymes present in the green vegetables regulate the moisture content in the skin cells. Circulation of proper quantity of blood to the various parts of the body is boosted by green veggies; as a result the nutrients are reached at the cellular level of our body.

Therefore, the importance of vegetables can be estimated by the benefits it provides to our skin. It is, therefore, necessary for us to add some quantity of vegetables in our diet. Let us now look at the most important vegetables.


Broccolis are the largest source of cell nourishing ingredients. The process of cell regeneration in our body is efficiently boosted by the enzymes present in this veggie.

People with bad skin must consider consuming this natural item from making their skin soft and glamorous.

The antioxidant present in the skin keeps our cells youthful and protect it from the various harmful agents available in the atmosphere.


Cabbages are the vegetables from the family of broccoli. Just like the broccolis, these green vegetables are also a high source of antioxidants. The amazing feature of this particular vegetable is that enough moisture is regulated in the cells; as a result cell damage is prevented.


Spinach is a high source of antioxidants and vitamins, which nourishes the cells present in our body. Consuming this leafy veggie regularly allows new cells to take birth. Skin damage can be treated instantly by the nutrients present in spinach.


Glutathione is the name of the antioxidant present in this particular vegetable. It destroys the pathogens from the skin, preventing the infection from happening. The cells are nourished by the nutrients, and enough blood reaches the cells. As a result, the dead cells are eradicated, giving enough space for the new cells to be born.

In various scientific researches, it has been found that people who eat vegetables live a much longer span of life than the people who consume non-vegetarian items.

It is because the nutrients present in vegetables are easily digested in our body and reaches even the remotest organs of the body.

Therefore, if you are willing to live long and healthy, vegetables must be consumed. They keep our cells nourished and provide instant protection from the harmful components of the atmosphere.

Having a healthier body is everyone’s dream, so you can definitely start today by fulfilling the recommended daily intake of glutathione precursors. By doing so, you are improving the level of glutathione in your body, resulting in a better immune system
