PRODUCT DESCRIPTION

The most important antioxidant in your body is one you cannot supplement directly – but you can give your cells exactly what they need to make it.

Glutathione sits at the centre of your entire antioxidant defence system – protecting liver cells, supporting immune function, clearing the respiratory tract, and neutralising oxidative damage at the cellular level. The problem: oral glutathione is largely broken down in the digestive tract before reaching systemic circulation. N-Acetyl Cysteine (NAC) bypasses this entirely – it is efficiently absorbed, enters cells directly, and is converted into cysteine, the rate-limiting precursor for intracellular glutathione synthesis. Within 30-90 minutes of dosing, glutathione levels measurably rise in liver, lung, and immune cells.

The 5XL Nutrition NAC delivers 600mg of pharmaceutical-grade N-Acetyl Cysteine per vegetarian capsule – the dose used across the majority of clinical research on NAC’s effects on liver health, immunity, respiratory function, and cellular antioxidant defence.

Why Choose The 5XL Nutrition NAC 600mg?

600mg – The Full Clinical Dose: Many NAC supplements use 200-400mg per capsule, requiring multiple capsules to reach a research-equivalent dose. The 5XL Nutrition NAC delivers 600mg in a single capsule – a complete clinical dose daily, or a clean foundation for twice-daily dosing at 1,200mg.
NAC Over Direct Glutathione – The Right Choice: Oral glutathione is hydrolysed by digestive enzymes before reaching circulation. NAC is absorbed as an amino acid derivative, enters cells, and synthesises glutathione exactly where it is needed. This is why NAC is consistently preferred by clinicians and researchers over direct glutathione supplementation.
Pharmaceutical-Grade Purity: Manufactured to the same quality specification used in hospital IV formulations – not industrial-grade NAC. Third-party tested for purity and potency with every batch.
Clean Vegetarian Formula: HPMC vegetarian capsule. No artificial colours, flavours, or preservatives. Non-GMO, gluten-free, and free from animal-derived excipients.

Key Benefits of NAC 600mg

Raises Glutathione – The Master Antioxidant: NAC’s primary and most fundamental benefit. Higher cellular glutathione means better neutralisation of free radicals, improved detoxification enzyme function, and stronger antioxidant protection across every tissue.
Liver Protection and Detox Support: The liver uses glutathione as its primary Phase II detoxification molecule. NAC replenishes hepatic glutathione, supporting ongoing detox capacity and protecting liver cells from oxidative injury – the same mechanism behind NAC’s use in paracetamol overdose treatment for over 50 years.
Respiratory Health and Mucus Clearance: NAC directly breaks disulfide bonds in mucin, reducing mucus viscosity and improving respiratory tract clearance – independently of its glutathione effects. Particularly relevant for anyone in high-pollution environments or with recurrent respiratory symptoms.
Immune System Resilience: Glutathione is essential for T-lymphocyte and natural killer cell function. NAC restores glutathione in immune cells, supporting faster and more effective responses to infection – especially critical during heavy training, stress, or illness.
Reduces Exercise-Induced Oxidative Stress: Intense exercise rapidly depletes glutathione and generates muscle oxidative damage. NAC reduces post-training oxidative stress markers, supporting faster recovery and reduced muscle damage per session.
PCOS and Mental Health Support: Multiple RCTs show NAC improves insulin sensitivity, menstrual regularity, and ovulation in PCOS. Emerging research also shows consistent results for OCD and compulsive behaviours through NAC’s modulation of glutamate neurotransmission. Use under medical supervision for both applications.

Take 1 capsule (600mg) once or twice daily with water, with or without food.

Goal	Daily Dose	Timing
General antioxidant & liver support	600mg (1 capsule)	Morning with breakfast
Active liver detox / pollution exposure	1,200mg (2 capsules)	Morning + evening
Athletic recovery	1,200mg	Pre- or post-workout

Stack with Astaxanthin + COQ10 for comprehensive antioxidant coverage across membrane, cytoplasmic, and mitochondrial pathways
Stack with Milk Thistle or Liver King for complete liver protection
Ensure adequate B12, B6, and folate intake at higher long-term doses to support homocysteine metabolism
Note: NAC has a natural sulphurous smell — normal, not a sign of degradation

FAQs

What is the price and how long does one bottle last?

₹1,124 – 25% off ₹1,499. 60 days at 1 capsule/day or 30 days at 2 capsules/day. Approximately ₹18.7 per day at the standard dose. Free shipping pan-India.

Why take NAC instead of glutathione directly?

Oral glutathione is broken apart by digestive enzymes before reaching the bloodstream. NAC is absorbed efficiently, enters cells directly, and synthesises glutathione intracellularly – exactly where it’s needed. This is why NAC is the gold standard for raising cellular glutathione levels.

Can NAC help with PCOS?

Yes, Multiple clinical trials show NAC at 1,200-1,800mg daily improves insulin sensitivity, ovulation rates, and menstrual regularity in PCOS – with results comparable to Metformin and fewer side effects. Consult your gynaecologist before use.

Is NAC helpful for OCD or mental health?

Multiple RCTs show significant symptom reductions in OCD, trichotillomania, and compulsive behaviours with NAC 1,200-2,400mg daily through modulation of the brain’s glutamate transporter system. Always use under psychiatrist guidance for mental health applications.

Does NAC benefit athletes?

Yes, NAC reduces exercise-induced oxidative damage markers, supports faster recovery between sessions, and has been shown to improve endurance performance. For athletes training 4+ times per week, NAC provides meaningful antioxidant recovery support.

How do I verify my NAC is genuine?

Every bottle has a unique authenticity code. Visit the5xlnutrition.com/verify-product and confirm in under 30 seconds. Pharmaceutical-grade NAC costs more to produce – always verify before your first capsule.
