What is N-acetylcysteine ?

N-acetylcysteine, often abbreviated to NAC, is a stable form of cysteine, a sulfur-containing amino acid naturally present in the body. In particular, it is known as the direct precursor of glutathione, one of the body’s most powerful antioxidants.

Initially used in medicine to thin bronchial secretions and as an antidote to intoxications (notably paracetamol), NAC is now recognized for its many benefits to overall health, particularly in the fields of liver detoxification, cellular protection, immune support and hormonal well-being.

At MiYé, NAC can be integrated into a functional approach to women’s well-being, notably to accompany hormonal imbalances, support the liver (a key organ of hormonal regulation) and combat oxidative stress.

Where does N-acetylcysteine come from ?

NAC is obtained by chemical modification of cysteine, an amino acid naturally present in animal and plant proteins. This “acetylated” form of cysteine is more stable and better assimilated by the body than free cysteine. It has been used for decades in hospitals, but is now available in food supplements for wellness use, where it is extracted using pharmaceutical-grade processes.

Properties and active ingredients

N-acetylcysteine acts on several levels: antioxidant, cellular metabolism and hepatic support. Its main actions are detailed below:

• Glutathione precursor: NAC enables the synthesis of glutathione, considered the body’s master antioxidant. It neutralizes free radicals, promotes cell repair and supports the immune system.
• Liver function support: Protects the liver against environmental toxins, excess hormones, food and medication. It is often used in gentle detoxification programs.
• Inflammation regulation: By limiting the production of certain cytokines, it helps modulate chronic inflammatory responses, notably in hormonal disorders such as endometriosis or PCOS.
• Mucolytic effect: It thins secretions, making it an interesting support for the ENT sphere or in cases of persistent respiratory infections.
• Neuroprotective support: Studies suggest that it may have a positive effect on concentration, mood and even certain neurological disorders linked to oxidative stress or inflammation.

What are the benefits of N-acetylcysteine ?

NAC offers a very comprehensive action on the body, going far beyond its initial respiratory applications. It is particularly beneficial for women exposed to chronic oxidative stress, hormonal imbalances or endocrine disruptors.

Its most recognized benefits include

• Liver detoxification: Helps eliminate excess hormones (estrogen, cortisol…) and metabolic waste, contributing to a better hormonal balance.
• Support for natural defenses: By increasing glutathione levels, it boosts immunity and helps the body to better cope with external aggressions (pollution, viruses, etc.).
• Reduces oxidative stress: By neutralizing free radicals, it protects cells from premature aging, benefiting skin, ovaries and neurons.
• Improves fertility: It is sometimes used to support fertility treatments, notably to improve oocyte quality or cervical mucus.
• Positive effect on mood and concentration: Research shows interesting effects in cases of mental fatigue, brain fog or periods of overwork.
• How should N-acetylcysteine be taken?

NAC is generally available in capsule or powder form for dilution. It is well absorbed orally and can be incorporated into a daily vitality support routine.

Directions for use :

Recommended dose: between 600 mg and 1,200 mg per day, in one or two doses as required.

Best taken on an empty stomach or between meals for better absorption.

A course of treatment lasting 1 to 3 months is often recommended for lasting effects.

Any side effects ?

NAC is generally well-tolerated, but some people, particularly those taking high doses, may experience side effects:

• Slight digestive problems: such as nausea, stomach pains or bloating at the start of the treatment.
• Sulfurous odor**: typical of the molecule, it may be noticeable in taste or breath, although this remains transitory.
• Interaction with certain medicinal products

Sources

N-acetylcysteine is supported by a vast body of scientific literature, in both the medical and nutritional fields. Its effects on glutathione, liver function and cellular protection are well documented. It has also been studied in hormonal, inflammatory and neurological contexts, making it an increasingly important ally in integrative approaches to well-being.
