GlyNAC with Glycine and N-Acetylcysteine (NAC)

GlyNAC is a dietary supplement combining glycine and N-acetylcysteine (NAC), a source of cysteine – two amino acids used by the body in the synthesis of glutathione, one of the body's major intracellular antioxidants.

This combination is the subject of growing scientific interest in the fields of antioxidant biology and Healthy Aging.

Each daily serving provides 600 mg of glycine and 600 mg of NAC. One bottle provides a 60-day supply at a serving of 2 capsules per day.

GlyNAC: Why Combine N-acetylcysteine (NAC) and Glycine?

The three components of glutathione

Glutathione is an intracellular antioxidant naturally produced by the body. It is composed of three amino acids:

• cysteine;
• glycine;
• and glutamate.

Why use NAC as a source of cysteine?

N-acetylcysteine (NAC) is an acetylated form of cysteine commonly used in dietary supplement formulations.

Once available to the body, NAC can provide cysteine, one of the amino acids required for normal glutathione synthesis.*

For this reason, NAC has been widely studied in relation to glutathione metabolism and normal cellular antioxidant processes.*

Why combine glycine with N-acetylcysteine (NAC)?

Glycine is another amino acid required for the body's normal synthesis of glutathione.

Combining glycine with NAC therefore provides two of the three amino acid components used to produce glutathione.

GlyNAC combinations have attracted scientific interest because they provide both glycine and a source of cysteine within the same nutritional formula.*

This product provides 600 mg of NAC and 600 mg of glycine per daily serving, maintaining a 1:1 ratio.

Why is glutamate not added?

Glutamate is the third amino acid component of glutathione and is naturally present in the body and in a wide variety of foods.

This formula therefore focuses specifically on supplying glycine and NAC as a source of cysteine.

GlyNAC, Glutathione and Cellular Antioxidant Defenses

Glycine and NAC as glutathione precursors

GlyNAC provides glycine and a source of cysteine, two amino acids involved in the body's normal production of glutathione.*

Glutathione participates in the body's normal cellular antioxidant systems and helps maintain normal cellular redox balance.*

What is the role of glutathione?

Glutathione is naturally present within cells and participates in several normal physiological processes.

• It participates in normal cellular antioxidant defenses and redox balance.*
• It is involved in enzymatic reactions that help cells manage reactive compounds produced during normal metabolism.*
• It serves as a cofactor for enzymes including glutathione peroxidase, which participates in normal antioxidant processes.*

What does clinical research say about GlyNAC?

GlyNAC combinations have been evaluated in human clinical research, including studies involving older adults.

These studies have investigated the effects of combined glycine and NAC supplementation on parameters including glutathione status, oxidative balance and other physiological markers associated with healthy aging (4-5).*

Clinical studies use specific populations, study durations and dosing protocols. Their results should therefore be interpreted within the context of each individual study.

4 Potential Key Benefits and Reasons to Buy our GlyNAC Formula

GlyNAC stands out for 4 key characteristics:

1. A complementary glycine + NAC formula: unlike supplements containing NAC alone, GlyNAC provides both glycine and N-acetylcysteine, supplying two amino acid components involved in normal glutathione synthesis.*
2. 600 mg of NAC and 600 mg of glycine per daily serving: the formula provides these two ingredients in a 1:1 ratio. One bottle provides a 60-day supply at 2 capsules per day.
3. Fermentation-derived NAC: the N-acetylcysteine used in this formula is obtained through a fermentation process.
4. A simple composition: the formula is provided in hypromellose vegetable capsules and contains acacia gum as the sole excipient.

Who is GlyNAC Intended For?

GlyNAC is intended for adults looking to complement their diet with glycine and NAC and support normal glutathione production and cellular antioxidant defenses.*

• Adults interested in healthy aging: GlyNAC has attracted scientific interest in research examining glutathione metabolism and physiological changes associated with aging.*
• People looking to support normal glutathione production: glycine and cysteine are two of the amino acid components required for glutathione synthesis.*
• People looking for antioxidant nutritional support: glutathione participates in normal intracellular antioxidant processes.*
• Those who prefer a combined formula: GlyNAC provides both glycine and NAC within the same daily supplement.

Which Dietary Supplements Can Complement GlyNAC?

Selenium

Selenium is an essential trace element that contributes to the protection of cells from oxidative stress.*

Selenium is also a component of glutathione peroxidase enzymes, which participate in the body's normal antioxidant systems.

Adults interested in complementary antioxidant nutrients may therefore consider a selenium supplement such as Selenium.

NAD+ precursors

NAD+ is a naturally occurring coenzyme involved in numerous cellular reactions, including normal energy metabolism.

Ingredients involved in NAD+ metabolism are also being studied in the context of cellular function and healthy aging.*

For adults interested in this complementary nutritional approach, see NAD+ Booster Formula.

PQQ and coenzyme Q10

Coenzyme Q10 participates in the mitochondrial electron transport chain involved in normal cellular energy production.*

PQQ is another compound being investigated in research relating to normal mitochondrial processes.

These ingredients are combined in PQQ & Q10 for adults interested in complementary nutritional support for normal cellular energy processes.*

Glycine, Cysteine and Glutathione Synthesis

Why are glycine and cysteine important?

Glycine and cysteine are two of the three amino acid components required by the body to synthesize glutathione.

Their availability depends on several factors, including normal metabolism, dietary intake and individual physiological requirements.

GlyNAC provides both glycine and NAC as a source of cysteine within a single formula.

Why is glutathione important?

Glutathione is naturally produced within the body and contributes to normal intracellular antioxidant and redox processes.*

Providing nutritional precursors such as glycine and cysteine supports the normal pathways involved in glutathione synthesis.*

Quality, Purity and Traceability
