In the body, NAC is converted to L-cysteine, which is the rate-limiting precursor for glutathione synthesis. Glutathione is the body's primary intracellular antioxidant. NAC provides cysteine to support the body's own glutathione production.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMore Stable Than L-Cysteine:\u003c\/strong\u003e The acetyl group attached to NAC makes it more stable and better absorbed than L-cysteine alone. L-cysteine is prone to oxidation and has lower oral bioavailability. NAC is the preferred supplemental form for raising cysteine and glutathione levels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMucolytic Action:\u003c\/strong\u003e NAC has a free thiol (SH) group that breaks the disulfide bonds holding mucus proteins together. Mucus gets its thick, sticky consistency from these disulfide bonds between mucin proteins. By breaking them, NAC reduces mucus viscosity, making it thinner and easier to clear. This is the basis for the mucolytic use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVegan Hypromellose Capsule:\u003c\/strong\u003e The capsule shell is made from hypromellose, a plant-derived cellulose. Suitable for vegans and vegetarians.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2-Pack Value:\u003c\/strong\u003e This listing contains 2 x 300 capsule bottles of the same NAC 600mg formula (NPN 80078286). At 1 capsule per day, this is a 600 day supply (approximately 20 months).\u003c\/p\u003e\n\u003ch3\u003eWhat This Product Does\u003c\/h3\u003e\n\u003cp\u003eNAC 600mg is a source of cysteine for the synthesis of glutathione (an antioxidant). It provides antioxidant activity. It supports liver function. It acts as a mucolytic agent to help thin and loosen mucus. These are the Health Canada approved uses (NPN 80078286). This product is not intended to diagnose, treat, cure, or prevent any disease.\u003c\/p\u003e\n\u003ch3\u003eWhat Is NAC (N-Acetyl-L-Cysteine)?\u003c\/h3\u003e\n\u003cp\u003eN-Acetyl-L-Cysteine (NAC) is a modified form of the amino acid L-cysteine. The modification is an acetyl group (a small chemical group) attached to the nitrogen of cysteine. This acetylation makes NAC more chemically stable and better absorbed by the body than L-cysteine alone.\u003c\/p\u003e\n\u003cp\u003eOnce absorbed, NAC is converted back to L-cysteine in the body. L-cysteine is then used to make glutathione, the body's most important intracellular antioxidant. Cysteine is the rate-limiting ingredient in glutathione synthesis, meaning the body can only make as much glutathione as the available cysteine allows. Supplementing with NAC provides additional cysteine to support glutathione production.\u003c\/p\u003e\n\u003cp\u003eNAC also has direct antioxidant activity through its free thiol (SH) group, which can neutralize certain reactive oxygen species directly.\u003c\/p\u003e\n\u003ch3\u003eUnderstanding the Ingredient Content\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eNAC (N-Acetyl-L-Cysteine):\u003c\/strong\u003e 600mg per capsule\u003cbr\u003e\u003cstrong\u003eSuggested Use:\u003c\/strong\u003e Adults: 1 capsule daily.

It is the most abundant antioxidant inside your cells and plays a central role in protecting cells from oxidative damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy Cysteine Is the Limiting Factor:\u003c\/strong\u003e Your body can usually get enough glutamate and glycine from food. Cysteine is the amino acid that limits how much glutathione your body can make. When cysteine is in short supply, glutathione production slows. NAC provides a stable, well-absorbed source of cysteine to support glutathione synthesis.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGlutathione and the Liver:\u003c\/strong\u003e The liver is the organ with the highest concentration of glutathione in the body. Glutathione plays a key role in the liver's detoxification processes, particularly in Phase II detoxification reactions where it conjugates (binds to) toxins and metabolic waste products to make them water-soluble for excretion. This is the biochemical basis for NAC's liver support use.\u003c\/p\u003e\n\u003ch3\u003eNAC as a Mucolytic Agent\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat a Mucolytic Does:\u003c\/strong\u003e A mucolytic is a substance that breaks down mucus, making it thinner and easier to clear from the airways.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow NAC Works as a Mucolytic:\u003c\/strong\u003e Mucus gets its thick, sticky consistency from disulfide bonds between mucin proteins. These are chemical bonds formed between sulfur atoms on adjacent mucin molecules. NAC has a free thiol (SH) group that can break these disulfide bonds, reducing the cross-linking between mucin proteins and making the mucus less viscous and easier to clear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Sulfurous Smell:\u003c\/strong\u003e NAC and cysteine contain sulfur, which gives them a characteristic smell. This is normal and does not indicate spoilage or reduced quality.\u003c\/p\u003e\n\u003ch3\u003e2-Pack vs. Single Bottle: What Is the Difference?\u003c\/h3\u003e\n\u003cp\u003eBoth listings contain the same NAC 600mg formula (NPN 80078286) in the same 300-capsule bottles. The single bottle listing provides 300 capsules (300 day supply at 1 per day). This 2-pack listing provides 2 x 300 capsules = 600 capsules total (600 day supply at 1 per day, approximately 20 months).
