What are Glycine & NAC Supplements?

Glycine is a non-essential amino acid that plays a crucial role in the synthesis of proteins, collagen, and other vital compounds in the body. It supports healthy metabolic processes, aids in muscle repair, and promotes better sleep and cognitive function. N-Acetyl Cysteine (NAC) is a supplement derived from the amino acid cysteine. It is known for its antioxidant properties, helping to replenish glutathione levels, which protect cells from damage. NAC is often used to support liver function, respiratory health, and to boost immune system performance.

The Science Behind Glycine & NAC Supplements

Glycine works by serving as a building block for proteins, collagen, and neurotransmitters, playing a crucial role in various metabolic pathways. It acts as an inhibitory neurotransmitter in the central nervous system, promoting calmness and regulating sleep. Glycine is also involved in the synthesis of glutathione, a vital antioxidant that protects cells from oxidative stress. NAC (N-Acetyl Cysteine) supplements function by replenishing intracellular levels of cysteine, a precursor to glutathione. This boosts the production of glutathione, enhancing the bodyís ability to neutralize free radicals and detoxify harmful substances. NAC also helps in breaking down mucus in the lungs, improving respiratory function by reducing the viscosity of mucus and promoting its clearance.

Glycine & NAC Benefits

  • Antioxidant Properties

    Glycine and NAC both contribute to the synthesis of glutathione, a powerful antioxidant that helps protect cells from oxidative damage.

  • Improved Detoxification

    The combined effect of Glycine and NAC enhances liver function by supporting the detoxification pathways, helping to eliminate toxins more effectively.

  • Improved Sleep

    Glycine's calming effect on the nervous system, along with NAC's ability to modulate neurotransmitters, can improve sleep quality and stabilize mood.

  • Stronger Immunity

    Together, these supplements boost immune function by maintaining optimal glutathione levels, which are crucial for a healthy immune response.

  • Reduced Inflammation

    Both Glycine and NAC have anti-inflammatory properties that can help reduce chronic inflammation, potentially lowering the risk of various inflammatory diseases.

  • Respiratory Health

    The mucolytic properties of NAC combined with the overall metabolic support of Glycine can improve respiratory function by reducing mucus build-up and promoting clear airways.

How Glycine and NAC Works


Glutathione Synthesis

Both Glycine and NAC are precursors to glutathione, a critical antioxidant in the body. NAC provides cysteine, which combines with glycine and glutamate to form glutathione. This process enhances the bodyís ability to neutralize free radicals and reduce oxidative stress, protecting cells from damage and supporting overall cellular health.


Detoxification Support

NAC enhances liver function by increasing glutathione levels, which play a vital role in detoxifying harmful substances. Glycine also contributes by forming bile salts that help process and eliminate toxins. Together, they improve the liverís capacity to detoxify the body, promoting a healthier metabolic environment.


Neurotransmitter and Metabolic Regulation

Glycine acts as an inhibitory neurotransmitter in the central nervous system, promoting relaxation and better sleep quality. NAC, through its modulation of glutamate and dopamine levels, supports mental health and cognitive function. This combination helps in regulating mood, reducing anxiety, and improving overall neurological health.

    People NAC is brilliant, but I highly recommend taking it with Glycine, it makes all the difference, hence why it is often sold as one.
