Nutricost NAC Review 2026: 1,000 mg Tablets, Testing and Value

Nutricost NAC stands out for high-dose value rather than dose flexibility. The current direct-sale tablet provides 1,000 mg NAC per tablet and is sold in 120- and 240-tablet options. The 120-tablet bottle is currently listed at $19.97.

Formula and product claims

Nutricost's current direct product page lists 1,000 mg NAC per tablet with 120- and 240-tablet options. The brand labels the product vegan and gluten-free.

Price and cost per gram

The 120-tablet bottle at 1,000 mg each contains 120 grams of NAC. At the current $19.97 price, that is a very low ingredient cost per gram.

This is where Nutricost makes the strongest case: buyers who genuinely want around 1,000 mg at a time get a large amount of NAC without paying premium-capsule prices.

ConsumerLab 2026 testing

ConsumerLab's public 2026 NAC report names Nutricost NAC among the products included in its independently purchased test set.

ConsumerLab says all tested products contained their labeled amount within an acceptable margin.

We are careful not to overstate that result: the public summary does not establish that every current Nutricost bottle size or formulation is identical to the exact sample ConsumerLab tested.

The 1,000 mg trade-off

A 1,000 mg tablet is convenient when your target is 1,000 or 2,000 mg/day. It is less convenient when the evidence you are following uses 600 mg or 1,200 mg/day.

That is not a potency problem. It is a dose granularity problem.

If you want fine control, a 500-600 mg capsule or powder may fit better. See NAC powder vs capsules.

What Nutricost gets right

• Low cost per gram.
• High-dose convenience.
• Third-party testing claim.
• ConsumerLab 2026 brand inclusion.
• Large-count options.

What we would improve

• 1,000 mg is not very flexible: awkward for common 600 mg increments.
• Facility certification language can be misunderstood: “produced in an NSF-certified facility” is not the same as this NAC product being NSF Certified for Sport.

Nutricost vs NOW NAC

	Nutricost	NOW
Unit dose	1,000 mg tablet	600 mg capsule
Best feature	High-dose value	Flexible 600 mg dose + broad availability
ConsumerLab 2026	Brand included	600 mg and 1,000 mg products included
Added selenium	No headline selenium addition	25 mcg/capsule in current 600 mg U.S. formula

Who should buy it?

Best fit: value-focused buyers who specifically want a high-dose NAC tablet and do not need 600 mg dose increments.

Less ideal: someone titrating lower doses, following a 600 mg-based protocol, or wanting powder-level dosing flexibility.

Cost normalized to NAC amount

At $19.97 for 120 × 1,000 mg tablets, the bottle contains 120 g NAC. That is about $0.17 per gram, or roughly $0.10 per 600 mg equivalent. It is the lowest normalized ingredient cost among the branded products in this comparison, but the 1,000 mg tablet gives less dose flexibility.

Bottom line

Nutricost NAC is a high-dose value play. The current 1,000 mg tablet is inexpensive per gram, the brand provides quality/manufacturing claims, and Nutricost appeared in ConsumerLab's 2026 independent NAC test set. The main downside is simply that 1,000 mg tablets are less flexible than standard 500-600 mg capsules.
