Give Back Health Clinic Collection NAC is a practitioner-only nutritional supplement that provides fermented, vegan and 100% pure medicine-grade NAC. Boasting a popular natural orange flavour for improved patient compliance, it comes in powder form and is designed for extemporaneous compounding and prescribing under practitioner supervision. N-acetyl cysteine (NAC) is a sulfur containing amino acid that helps normalise compromised glutamatergic neurotransmission. It is a precursor for cysteine – a building block and rate-limiting step in glutathione (GSH) formation. NAC shows a high degree of promise in preconception care, endometriosis, mental health, detoxification and as a bio-film disruptor.

• Normalises compromised glutamatergic neurotransmission, making it highly effective as a mental health nutrient.
• Helps optimise fertility for both males and females.
• It is a major anti-inflammatory, mucolytic and bio-film disruptor.
• Helps reduce cravings and relapse risk in addiction.

Potent antioxidant

• Precursor for cysteine- a building block and rate-limiting step in GSH formation.
• GSH is a substrate for various antioxidant enzymes.
• Direct antioxidant via thiol (SH) content to NO2 and HOX.
• Restores thiol pools.
• Involved in redox homeostasis and signalling networks.

Mental health

• Normalises compromised glutamatergic neurotransmission.
• Cerebral oxidative stress is mitigated by NAC via the upregulating of Nrf2 (Nuclear factor erythroid 2-related factor 2) and providing the cysteine required for GSH generation within the brain.
• Improves the efficiency of the cysteine-glutamate exchange system.
• Benefits NMDA receptor functions.
• Improves cerebral mitochondrial function and reduces neuroinflammation.

Potent anti-inflammatory

• Antioxidant action in Cox-2 pathway.
• Inhibits NF-kB activation.
• Specific anti-inflammatory effect on IL-6.
• Decreases pro-inflammatory cytokines.
• Downregulates inflammatory protein activity and modulates redox-sensitive transcription factors.

Anti-angiogenic

• Inhibition of vascular endothelial growth factor (VEGF).
• Inhibition of metalloproteinase (MMP) expression.

Detoxification

• NAC involved in the detoxification of semiquinones (phenoxyl radicals), hypochlorous acid (HOCl), nitroxyl (HNO), and heavy metals.
• Promotes phase II detoxification via specific GSH S-transferases which mediate the conjugation of GSH and the removal of various xenobiotic compounds.

Mucolytic

• NAC provides free sulfhydryl groups (-SH) which break open mucin disulphide bonds and other cross-linked disulphide bridges in the tertiary structure of the mucoproteins, which increases the fluidity of the mucous.

Anti-infective actions

• Normal, fluid mucus in airways allows soluble antibacterial factors and neutrophils (or antibiotics) access to the infecting bacteria.
• Bacterial adherence is inhibited in fluid mucous.
• NAC provides direct bacteriostatic action by breaking disulphide bonds of bacterial proteins.
• Potent anti-oxidant and antiinflammatory.
• Reduces pathological mucus formation by protecting airways from oxidative stress and inflammation.

Biofilm disruptor

• Reduces the opportunity for biofilm producing bacteria (such as Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae) to flourish.
• Decreases production of extracellular polysaccharides which are required for biofilm formation.

Autism Spectrum Disorder

• Normalises oxidative stress and antioxidant systems.

Craving and addiction

• Improves the efficiency of the cysteine-glutamate exchange system (which are implicated in craving and addiction).
• Restores the Glial Glutamate transport (GLT1) system and improves NMDA receptor function (disruptions may be associated with drug-seeking behaviour).
• Restores glutamate levels; low glutamate is a determinant of relapses in addiction.
• Reduces local tissue damage caused by exposure to drugs.
• Stabilises mesolimbic dopamine release.
• Increases glutathione which reduces oxidative stress and neuroinflammation.
• Reduces pro-inflammatory cytokines which reduces relapse vulnerability.

Fertility and reproductive health optimisation

• Reduced sperm quality and damaged sperm DNA linked to excess ROS damage.
• Oxidative stress is linked to unexplained infertility, pregnancy complications, spontaneous abortion, and recurrent pregnancy loss, endometriosis and PCOS have all been linked to oxidative stress.
• NAC has multiple antioxidant actions against a range of free radicals.
• Intra and extracellular glutathione (GSH) precursor.
• Major anti-inflammatory (inhibits proinflammatory cytokines).
• Antiangiogenic action.

Environmental, lifestyle and xenobiotic detoxification

• Restores intracellular and extracellular glutathione levels.
• Supports phase II detoxification pathways.
• GSH is a substrate or cofactor for many detoxifying cellular enzymes.
• Glutathione levels are reduced in pro oxidant environments and due to ageing.

Mucolytic and bio-film disruptor

• Viscous mucous disrupts immune system response to infection and encourages biofilm formation.
• NAC reduces the viscosity of mucous by disrupting crosslinked bonds in muco-glycoproteins.
• NAC has anti-infective properties.
• Intra and extracellular glutathione precursor.
• Major anti-inflammatory (inhibits pro-inflammatory cytokines).

When selecting an NAC product, key factors include clinical research on the raw material, clinical dosing, purity, excipient profile and manufacturing standards. Unlike herbal ingredients, which are complex and vary significantly across the many different grades available, single nutrients are far simpler to assess. Source and quality are still essential, but they are much easier to control and verify. If a material is authenticated and genuinely pure, the body can be expected to respond the same way regardless of supplier or brand name. Where this cannot be confirmed, the supplier and manufacturing process become critical.

The key questions to ask are: Is it pure? Has every batch been independently tested to confirm this? Is it free from impurities? Is it the correct isomer, where relevant? Is it stable over time and in combination with other ingredients?

Our NAC meets every one of these criteria. It is authenticated, independently tested on every batch, free from impurities, the correct isomer where relevant, and stable, so you can be confident you are receiving the full clinical dose stated on the label.

This product has been specifically developed for practitioner use and compounding, with:

• High-quality, verified raw materials with full traceability.

• Manufacturing in a TGA-licensed GMP facility in Australia.

• Rigorous third-party testing to ensure potency, purity and absence of contaminants.

• Patient compliance. NAC has quite a sulphury profile (as it contains a high content of sulphur, which is in part why it is such an effective ingredient) and our natural orange flavour has proved popular with patients.

This is a clean formula with 95% pure biofermented vegan NAC powder. The remaining 5% is made up of sulfite free natural orange flavour, a small amount of stevia leaf extract plus a very small quantity of riboflavin to help with the orange colour. This 5% excipient content, containing natural orange flavour, sweetener and riboflavin is to help with patient compliance as NAC is otherwise such a strong tasting ingredient. Citrus goes very well with NAC to balance the organoleptic properties and sulphur taste and we’ve had many practitioners and patients tell us that this is their favourite tasting NAC to date. 

In short, yes. Powders for extemporaneous compounding sit in a unique therapeutic category with its own set of rules. When you choose to use a compounding powder, the expectation is that you will be combining this with other therapeutic nutrients and ingredients to create a personalised medicine. Single ingredient prescribing is, however, possible with extemporaneous compounding ingredients with best practice to ensure that the amount of product in the jar represents the full course for the patient. The quantity of any ingredient you use will be calculated in relation to the prescription length and daily required dose, which is completely specific to an individual patient’s presentation and needs.

• Nitroglycerin: NAC can increase the risk of hypotension and headaches when taken with intravenous or transdermal nitroglycerin.

NAC has been studied in pregnant women for specific applications including preeclampsia and threatened preterm labour. When used orally, N-acetyl cysteine crosses the placenta, but has not been associated with adverse effects to the foetus. N-acetyl cysteine should only be used in pregnancy when clearly indicated.

• As NAC can be very strong on the stomach, general recommendations are to take it with a small amount of food. In certain instances taking on an empty stomach is absolutely applicable. Check with the literature relating to the indication.
• The common range for NAC is 1,000 mg – 3,000 mg per day. It is generally well tolerated at these levels, but monitor.
• Without knowing your patient’s presentation and requirements, we cannot provide guidelines around appropriate daily dosing and suggest you refer to the literature and common dosage ranges when creating your prescription. Our team of naturopaths are also available for further guidance.

Results are generally seen within 2-4 weeks, with further improvement by 6-12 weeks.
