EVO - N-Acetyl-L-Cysteine - cysteine

N-Acetyl-L-Cysteine - cysteine


N-Acetyl-L-Cysteine is a very underrated amino acid supplement form of cysteine, which is classified as 'semi-essential' because your body can still produce it from serine and other amino acids. However, for a lot of you reading this, you should consider it essential because many people have a poor dietary intake of amino acids in general, so they must depend on supplementation to get enough. The dangers of being deficient are you will struggle to boost antioxidants in the body, have a tough time with chronic breathing issues, have lower brain health, and much more.


N-Acetyl-L-Cysteine has many benefits that you should be excited about. The biggest one being antioxidant production in our body which suppresses and fights diseases. N-Acetyl-L-Cysteine replenishes glutathione, which freezes free radicals, causing damaged tissues and damages the good cells in our body. There is research showing it helps with anti-aging and much more.

Let's take a look at the supplement in depth, and figure out why it is so important, by listing the additional things it does:

    1. Immune boost: You might know someone who is always sick and there can be many reasons for this, including they are not getting enough proper nutrition. The good news is we have research showing that increasing N-Acetyl-L-Cysteine can not only boost the immune system but also restore it too. One particular study showed it is effective against influenza because it damages the virus. Another study showed that it contributes to cancer cell death and blocks cancer cells from multiplying.

    2. Oxidative Benefits: People who smoke or who are exposed to other environmental stresses will suffer from oxidative damage in the body. This will lead to heart problems among other things. N-Acetyl-L-Cysteine can help reduce tissue damage in the heart while also boosting nitric oxide production.
    3. Blood sugar: There is a connection to high blood sugar leading to fat tissue inflammation, which will lead to greater insulin resistance, which puts a person en route to becoming a type 2 diabetic. This trend has now reached over 25% of the USA population and growing quickly. N-Acetyl-L-Cysteine helps this problem by reducing inflammation and boosting insulin sensitivity. 
    4. Fertility: Men who use anabolic steroids will have a reduced sperm count. However, even if you do not use anabolics, we have seen a troubling trajectory of men with lower fertility across the western world thanks to environmental factors. The good news is N-Acetyl-L-Cysteine helps boost antioxidants which will fight free radicals in the reproductive system in both men and women

      Anabolic androgenic steroids (also known as AAS and steroids) are chemically modified versions or derivatives of the naturally-occurring male sex hormone, testosterone, which is produced naturally in both men and women. In other words, steroids refer to drugs (excluding estrogens, progestins, and corticosteroids) or hormonal substance(s), which are chemically related to testosterone that promotes muscle growth.

    5. Brain health: N-Acetyl-L-Cysteine boosts other amino acids, which means you protect your brain health by preventing damage to cells and reversing aging. A study showed that it slows down Alzheimer's, improves dopamine, and helps with memory.
    6. Breathing issues: If you cannot breathe you will have a tough time doing not just cardio, but also weight training. N-Acetyl-L-Cysteine not only helps with this, but it also can help you breathe while you sleep at night because it loosens mucus in the sinuses and also lowers inflammation in your lungs. A study showed people who suffered from chronic bronchitis and COPD (chronic obstructive pulmonary disease) had an improvement to their condition.
    7. Addictions and mental problems: N-Acetyl-L-Cysteine helps with this by regulating the neurotransmitter glutamate in our brain. One study showed that it helps lessen schizophrenia, while some early studies show it can help block cravings for things like marijuana and cigarettes.
    8. Organ Detox: You might be surprised to learn that N-Acetyl-L-Cysteine is sometimes included in IV's given to patients who have drug overdoses to prevent organ damage. It is a great detoxer of the liver and kidney's, which are two organs that come under tremendous stress from anabolic steroids, drugs, and alcohol.

Top foods

N-Acetyl-L-Cysteine can be boosted by consuming several types of foods:

    • Poultry: This includes turkey, chicken and other types of birds.
    • Dairy: Assuming it is derived from grass-fed animals, then raw cheese and yogurt have it.
    • Sunflower seeds: Make sure you consume it plain with no added oils.
    • Eggs: Eating humane friendly cage-free whole eggs is full of nutrition including many amino acids.

Side effects

You should never overdose on any supplements, however, N-Acetyl-L-Cysteine is safe even in high amounts. Your biggest risk when you take too much is stomach upset.

There is also a risk of slowing blood clotting if you are taking blood thinning medicine, so we don't recommend you use it if you have bleeding disorders.

It can also be taken as an IV, spray, liquid, or powder. It is considered most absorbable via IV, which is why hospitals give it with that method to patients in a dire situation.
