Nexus NAC - Unflavoured, 120g (150 Serves)

Nexus NAC Unflavoured is a 120g powder from Nexus for anyone who wants a straightforward daily antioxidant supplement rather than a flavoured pre-workout or protein blend. Each of the 150 servings delivers 800mg of N-Acetyl-L-Cysteine, the sole active ingredient, with zero calories, protein, carbs, fat and sugar on the nutrition panel. It sits in the Health & Wellness category at $47.96 NZD, built for a general wellbeing routine around a stable, unflavoured antioxidant precursor rather than a training-day supplement.

How Nexus Health & Wellness works

N-Acetyl-L-Cysteine is the acetylated form of the amino acid cysteine, chosen because it dissolves and absorbs more reliably than plain cysteine. Once inside the body, cysteine becomes the rate-limiting building block for glutathione, the cell's own internal antioxidant, assembled alongside glutamine and glycine. Supplying 800mg of NAC per serve gives the body one of the three raw materials it needs for glutathione production, rather than supplying glutathione directly, a molecule the body breaks down poorly when swallowed whole.

Glutathione plays a role in how the liver processes everyday toxins and in general immune and respiratory function, so keeping cysteine supply steady is a practical daily input for antioxidant defence, especially when training load and everyday stress are already high.

Why choose Nexus NAC

Nexus NAC Unflavoured keeps the ingredient list to one item, N-Acetyl-L-Cysteine at 100 percent, with no fillers or added flavours to formulate around. That makes it simple to slot into a stack that already includes a protein powder or a creatine, since it adds no flavour and no calories to compete with either.

• 800mg of N-Acetyl-L-Cysteine per serve, listed at 100% and standing as the only active ingredient on the panel
• 150 servings from a single 120g tub, keeping the per-serve cost low for a supplement most people take daily
• Zero calories, protein, fat, carbs, sugar, sodium and potassium per serve, so it sits cleanly alongside a tracked macro target

Getting the most from it

Nexus NAC Unflavoured mixes into water at any time of day, with or without food, so most people fold it into whatever routine already exists rather than timing it around training. It carries no flavour and no macros, so it stirs easily into a shaker alongside a scoop from the protein range or a serve of creatine without changing the taste of either. If you are assembling a broader daily stack, browse the full shop all range to see how Nexus NAC fits alongside other everyday wellbeing products.

One 0.8g serve a day is the standard pattern for Nexus NAC, taken consistently rather than cycled, since glutathione support works best as an ongoing daily input.
