N-Acetyl-Cysteine NAC (600mg) // Liver Support
F.A.Q.s
What is Leviathan NAC 600mg?
Leviathan NAC provides 600mg of N-Acetyl Cysteine per capsule in a 120-capsule bottle. NAC is a powerful amino acid derivative that supports glutathione production — the body’s master antioxidant — and is important for immune system support, liver health, and fighting cellular damage.
How does this compare to Strom NAC Powder?
Both provide high-quality NAC. Leviathan NAC offers convenient 600mg capsules, while Strom NAC Powder is more cost-effective for higher doses in the multi-gram range. Choose capsules for convenience, powder for flexibility and value at higher doses.
How many capsules should I take per day?
Follow the dosing instructions on the label. For general antioxidant and liver support, 1-2 capsules daily (600-1200mg) is common. Those seeking higher doses for enhanced support may take more — consult your healthcare professional for personalised guidance.
Who benefits from NAC supplementation?
Anyone looking to support liver health, antioxidant defence, and immune function. NAC is particularly popular among athletes under physiological stress, individuals supporting detoxification pathways, and those stacking comprehensive health protocols.
Can NAC be stacked with TUDCA and Liposomal Glutathione?
Yes. This is a powerful liver and antioxidant stack. NAC provides glutathione precursors, TUDCA protects liver cells through bile acid pathways, and Liposomal Glutathione delivers pre-formed glutathione directly. Together they provide comprehensive cellular protection.
Do you ship to New Zealand and Australia?
Yes. Strom Sports NZ is NZ-owned and operated, shipping from Ruapehu, New Zealand. We offer fast tracked shipping across New Zealand and to Australia. All orders include tracking so you can follow your delivery every step of the way.
